ABSTRACT

Abstract Objective To review knee magnetic resonance imaging (MRI) scans for the analysis of the location of neurovascular structures (NVSs), and to define the risk of bicortical fixation. Methods Distances between the posterior cortex and the popliteal NVSs were measured on the MRI scans of 45 adolescents (50 knees) at 3 levels (C1: center of the proximal tibial epiphysis; C2: 10 mm distal to the physis; and C3: 20 mm distal to the physis). The NVSs located between 5 mm and 10 mm from the incision were considered in a zone of moderate risk for damage, while those less than 5 mm from the incision were considered in a zone of high risk for damage, and those more than 10 mm from the incision were considered to be in a zone of low risk for damage. The independent Student t-test was used for the comparison of the NVS distance 0with gender, skeletal maturity, and the tibial tubercle-trochlear groove (TT-TG) distance. Values of p < 0.05 were regarded as statistically significant. Results The path of the C1 screw posed an increased risk of damage to the popliteal artery and vein compared with other screw paths (p < 0.001). The popliteal artery has a high risk of damage at the level of C1 (4.2 ± 2.2mm), and a moderate risk at C2 (9.6 ± 2.4mm), and the popliteal vein has a moderate risk at C1 (6.0 ± 2.7 mm), and a low risk at C2 and C3 (10.8 ± 3.1mm, and 12.05 ± 3.1mm respectively). The C3 position presented the lowest risk of damage to these structures (p < 0.001). The distance between the posterior tibial cortex and the posterior tibial nerve was < 15 mm at the 3 levels analyzed (C1: 11.0 ± 3.7 mm; C2:13.1 ± 3.8 mm; and C3:13 ± 3.9 mm). Conclusions The present study clarifies that the popliteal vessels are at risk of injury during tibial tubercle screw fixation, particularly when drilling the proximal tibial epiphysis. Monocortical drilling and screw fixation are recommended for the surgical treatment of tibial tubercle fractures. Level of Evidence III Diagnostic study.


Resumo Objetivo Revisar estudos de ressonância magnética (RM) do joelho para análise da localização das estruturas neurovasculares (ENVs) e definição do risco de fixação bicortical. Métodos As distâncias entre o córtex posterior e as ENVs poplíteas foram medidas nas RMs de 45 adolescentes (50 joelhos) em 3 níveis (C1: centro da epífise proximal da tíbia; C2:10 mm distalmente à fise e C3: 20 mm distalmente à fise). Considerou-se que as ENVs entre 5mme10mmda incisão estavam na zona de risco moderado de lesão, as ENVs a menos de 5 mm da incisão, na zona de alto risco de lesão, e as ENVs a mais de 10 mm da incisão, na zona de baixo risco de lesão. O teste t de Student independente foi usado para comparar a distância até as ENVs com o gênero, a maturidade esquelética e a distância entre a tuberosidade tibial e a garganta (fundo) da tróclea (TT-GT). Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados A trajetória do parafuso em C1 apresentou maior risco de lesão à artéria e à veia poplítea em comparação com outras trajetórias (p < 0,001). A artéria poplítea apresenta risco de lesão alto em C1 (4,2 ± 2,2 mm) e moderado em C2 (9,6 ± 2,4 mm), e a veia poplítea tem risco moderado em C1 (6,0±2,7 mm) e baixo em C2 e C3 (10,8±3,1 mm e 12,05±3,1mm, respectivamente). A posição C3 apresentou o menor risco de lesão dessas estruturas (p < 0,001). A distância entre o córtex tibial posterior e o nervo tibial posterior foi inferior a 15 mm nos 3 níveis analisados (C1: 11,0±3,7mm; C2: 13,1±3,8 mm; e C3: 13±3,9mm). Conclusões Este estudo esclarece que os vasos poplíteos correm risco de lesão durante a fixação do parafuso na tuberosidade tibial, principalmente durante a perfuração da epífise proximal da tíbia. A perfuração monocortical e a fixação com parafusos são recomendadas para o tratamento cirúrgico das fraturas da tuberosidade tibial. Nível de Evidência III Estudo diagnóstico.

ABSTRACT

El aneurisma de la arteria poplítea es el principal aneurisma periférico y el segundo en frecuencia después del aneurisma de la aorta abdominal. Su incidencia se desconoce. Posee un patrón característico de presentación que corresponde a personas del sexo masculinos, mayores de 65 años, con múltiples comorbilidades, donde la hipertensión arterial representa la más frecuente. La definición de aneurisma corresponde a una dilatación del 50 por ciento del diámetro del vaso, en el caso de la arteria poplítea, mayor de 1,5 cm. El 50 por ciento de los aneurismas poplíteos resulta asintomático, el resto presenta síntomas isquémicos (trombosis, embolismos periféricos), compresivos y la ruptura. El tratamiento es quirúrgico: convencional (vías medial-posterior) y endovascular. El objetivo del artículo fue presentar este caso por la infrecuencia del aneurisma de la arteria poplítea unilateral. Se trata de un paciente masculino de 62 años, con aumento de volumen localizado a nivel de la fosa poplítea izquierda con latido y expansión a la palpación, diámetro transversal aproximado de 3 cm y longitudinal de 4 cm, presencia de soplo sistólico a la auscultación con diagnóstico ecográfico y arteriográfico de aneurisma de la arteria poplítea izquierda. La evolución del paciente fue satisfactoria y se mantiene bajo seguimiento médico para evaluar la permeabilidad del injerto sintético(AU)


Popliteal artery aneurysm is the main peripheral aneurysm and the second in frequency after abdominal aortic aneurysm. Its incidence is unknown. It has a characteristic presentation pattern that corresponds to male people, over 65 years of age, with multiple comorbidities, where arterial hypertension represents the most frequent. The definition of aneurysm corresponds to a dilation of 50 percent of the diameter of the vessel, in the case of the popliteal artery, greater than 1.5 cm. 50 percent of popliteal aneurysms are asymptomatic, the rest have ischemic symptoms (thrombosis, peripheral embolisms), compression and rupture. Treatment is surgical: conventional (medial-posterior pathways) and endovascular. The objective of the article was to present this case due to the infrequency of the unilateral popliteal artery aneurysm. This is a 62-year-old male patient, with localized volume increase at the level of the left popliteal fossa with heartbeat and expansion on palpation, approximate transverse diameter of 3 cm and longitudinal diameter of 4 cm, presence of systolic murmur at auscultation with ultrasound and arteriographic diagnosis of aneurysm of the left popliteal artery. The patient's evolution was satisfactory and he remains under medical follow-up to evaluate the permeability of the synthetic graft(AU)

ABSTRACT

Abstract Background Despite significant improvements in outcomes, traumatic arterial limb injuries remain a significant cause of limb loss and mortality. Objectives This study sought to identify predictors of mortality and major amputation in patients undergoing revascularization after femoropopliteal arterial trauma. Methods This was a retrospective review of a trauma registry from an urban trauma center in Brazil. All patients admitted to our hospital with a femoropopliteal arterial injury from November 2012 to December 2017 who underwent vascular reconstruction were included. Univariate analyses and logistic regression analyses were conducted to identify factors independently associated with the primary outcome of amputation and the secondary outcome of mortality. Results Ninety-six patients were included. Eleven patients (11.5%) had an amputation and 14 (14.6%) died. In the logistic regression model for amputation, patients with ischemia duration greater than 6 hours were approximately 10 times more likely to undergo an amputation compared to those with ischemia duration less than or equal to 6 hours (adjusted odds ratio (AOR) [95% confidence interval (CI)]: 9.6 [1.2-79.9]). The logistic regression model for mortality revealed that patients with ischemia duration greater than 6 hours were approximately 6 times more likely to die compared to those with ischemia duration less than or equal to 6 hours (AOR [95% CI]: 5.6 [1.3 to 24.7). Conclusions Ischemia duration remains the most important factor independently associated with limb loss and mortality for patients undergoing femoropopliteal arterial revascularization after traumatic injuries. Physiological status on admission and trauma scores are also important.


Resumo Contexto As lesões arteriais traumáticas de membros ainda permanecem uma causa significativa de perda de membros e mortalidade, apesar de melhorias significativas observadas nos resultados após a ocorrências dessas lesões. Objetivos Este estudo buscou identificar preditores de mortalidade e amputações em pacientes submetidos à revascularização após trauma arterial femoropoplíteo. Métodos Esta é uma revisão de um Registro de Trauma Vascular. Todos os pacientes com lesão arterial femoropoplítea internados em nosso hospital de novembro de 2012 a dezembro de 2017 e submetidos a reconstrução vascular foram incluídos. Análises univariadas, seguidas de análises de regressão logística, foram realizadas para identificar fatores independentemente associados com os resultados primários de amputação e mortalidade. Resultados Foram incluídos 96 pacientes, com média de 27 anos. O Revised Trauma Score (RTS) foi, em média, 7,152; já o Injury Severity Score (ISS) foi, em média, 15. Onze pacientes (11,5%) tiveram amputação, e 14 pacientes (14,6%) morreram. Observou-se que pacientes com o tempo de isquemia maior que 6 horas apresentaram aproximadamente 10 vezes mais chance de amputação do que aqueles com tempo igual ou menor que 6 horas (intervalo de confiança de 95% [IC95%]: 1,2 a 79,9). O tempo de isquemia maior que 6 horas aumentou em aproximadamente 6 vezes a chance de mortalidade (IC95%: 1,26 a 24,77). A instabilidade hemodinâmica aumentou em 9 vezes a chance de mortalidade (IC95%: 2,36 a 36,67). Conclusões O tempo de isquemia continua sendo o fator mais importante independentemente associado a amputação e óbito em pacientes submetidos à revascularização arterial femoropoplítea após traumas. O estado fisiológico e os escores de trauma são importantes.

ABSTRACT

Abstract Peripheral vascular injuries are uncommon in civilian trauma but can threaten the patient's life or the viability of the limb. The definitive control of the vascular injury represents a surgical challenge, especially if the patient is hemodynamically unstable. This article proposes the management of peripheral vascular trauma following damage control surgery principles. It is essential to rapidly identify vascular injury signs and perform temporary bleeding control maneuvers. The surgical approaches according to the anatomical injured region should be selected. We propose two novel approaches to access the axillary and popliteal zones. The priority should be to reestablish limb perfusion via primary repair or damage control techniques (vascular shunt or endovascular approach). Major vascular surgeries should be managed post-operatively in the intensive care unit, which will allow correction of physiological derangement and identification of those developing compartmental syndrome. All permanent or temporary vascular procedures should be followed by a definitive repair within the first 8 hours. An early diagnosis and opportune intervention are fundamental to preserve the function and perfusion of the extremity.


Resumen El trauma vascular periférico no es común en el contexto civil, pero representa una amenaza para la vida del paciente o de la extremidad. El control definitivo de la lesión vascular representa un desafío quirúrgico, especialmente en pacientes con inestabilidad hemodinámica. Este artículo describe la propuesta de manejo del trauma vascular periférico de acuerdo con los principios de la cirugía de control de daños. Se debe identificar los signos sugestivos de lesión vascular y realizar oportunamente maniobras temporales para el control del sangrado. Se debe elegir el abordaje quirúrgico dependiendo del área anatómica lesionada. Se proponen dos nuevas incisiones para acceder a la región axilar y poplítea. La prioridad es restablecer la perfusión de la extremidad mediante el reparo primario o técnicas de control de daños (shunt vascular o abordaje endovascular). Los pacientes sometidos a cirugías vasculares mayores deben ser manejados postoperatoriamente en la unidad de cuidados intensivos para corregir las alteraciones fisiológicas e identificar aquellos que desarrollen un síndrome compartimental. Todos los procedimientos vasculares permanentes o temporales deben contar con un reparo definitivo en las primeras 8 horas. El diagnóstico temprano e intervención oportuna son fundamentales para salvaguardar la perfusión y funcionalidad de la extremidad.

ABSTRACT

Introducción. El síndrome de atrapamiento poplíteo es una entidad infrecuente, cuya incidencia oscila entre 0,17 y 3,5 %, representando una de las principales causas de isquemia en miembros inferiores en adultos jóvenes. Suele manifestarse con claudicación intermitente (69 %) o isquemia aguda (26 %), siendo muy rara su presentación con isquemia crítica de miembros inferiores. Caso clínico. Paciente de 30 años quien presentó úlcera subungueal en primer dedo de pie derecho con dolor intenso. En la exploración física no se palpaban pulsos distales y se observó palidez cutánea intensa y frialdad. Se realizó arteriografía donde se observó defecto de repleción de bordes regulares y desplazamiento medial de la arteria poplítea. La resonancia magnética mostró una inserción anómala del gastrocnemio medial, con lo que se hizo diagnóstico de síndrome de atrapamiento poplíteo tipo I. Mediante abordaje posterior se realizó reconstrucción vascular con injerto venoso y sección tendinosa del gastrocnemio medial. En el postoperatorio inmediato el paciente recupera pulso pedio y en el seguimiento a un año el paciente no presenta clínica de isquemia de miembros inferiores, encontrándose el baipás permeable. Discusión. A pesar de su baja incidencia, es importante incluir el síndrome de atrapamiento poplíteo en el diagnóstico diferencial de isquemia en miembros inferiores en adultos jóvenes. Su presentación con isquemia crítica es excepcional, encontrando muy pocos casos publicados en la literatura. La reconstrucción arterial precoz mediante injerto o plastia con material autólogo constituye el tratamiento de elección


Introduction. The popliteal entrapment syndrome is an infrequent entity, whose incidence ranges between 0.17 and 3.5%, representing one of the main causes of lower limb ischemia in young adults. It usually manifests with intermittent claudication (69%) or acute ischemia (26%), being very rare its presentation with critical ischemia of the lower limbs.Clinical case. A 30-year-old patient with a history of smoking, with no other risk factors, who presented with a subungual ulcer on the first right toe. On physical examination, distal pulses are not palpated, intense skin paleness and coldness are observed. Magnetic resonance imaging showed an anomalous insertion of the medial gastrocnemius with extrinsic compression of the popliteal artery, confirming a diagnosis of popliteal entrapment syndrome type I. Vascular reconstruction with venous graft and tendon section of the medial gastrocnemius was performed through a posterior approach. In the immediate postoperative period, the patient recovers a pediatric pulse and in the one-year follow-up the patient does not present symptoms of lower limb ischemia, finding the bypass patent. Discussion. Despite its low incidence, it is important to include popliteal impingement syndrome in the differential diagnosis of lower limb ischemia in young adults. Its presentation with critical ischemia is exceptional, finding very few cases published in the literature. Early arterial reconstruction by graft or plasty with autologous material is the treatment of choice

ABSTRACT

A artéria tibial anterior, originária da artéria poplítea, normalmente se ramifica abaixo da articulação do joelho, passando posteriormente ao músculo poplíteo. Desta forma, a existência da artéria tibial aberrante ocorre quando sua ramificação está alterada, podendo se formar em diferentes alturas da artéria poplítea e realizar cursos alterados em relação aos músculos e articulações. Essas variações podem aumentar o risco de lesões intra-operatórias. O objetivo deste estudo foi realizar revisão de literatura sobre o tema pouco abordado, visando promover maior conhecimento e prevenção de iatrogenia nos atos operatórios. Foi realizada busca em bases de dados eletrônicas (PubMed, Scielo e Biblioteca Virtual em Saúde) utilizando os seguintes descritores: artérias da tíbia, artéria poplítea, e variação anatômica. Para a seleção dos artigos, foram utilizados os seguintes critérios de inclusão: resultados de pesquisa com relevância ao tema proposto, por meio de leitura crítica de cada artigo selecionado e em seguida, foram realizadas comparações das informações de cada um deles. Foram selecionados 10 artigos. Em conclusão, a presença de artéria tibial anterior aberrante é alteração anatômica de baixa incidência, mas é responsável por intercorrências durante procedimentos cirúrgicos, devido à sua localização próxima à tíbia. Sugere-se realização de exames de imagens para diagnóstico pré-operatório dessa anormalidade anatômica.


The anterior tibial artery, originating from the popliteal artery, normally branches below the knee joint, passing posteriorly to the popliteal muscle. In this way, the existence of the aberrant tibial artery occurs when its branch is altered, being able to form at different heights of the popliteal artery and carry out altered courses in relation to the muscles and joints. These variations can increase the risk of intraoperative injuries. So, the proposal to this review was to promote greater knowledge and prevention of iatrogenesis in surgical procedures. A search was performed in electronic databases (PubMed, Scielo and Virtual Health Library) using the following descriptors: tibial arteries, popliteal artery, and anatomical variation. For the selection of articles, the following inclusion criteria were used: research results with relevance to the proposed topic, through a critical reading of each selected article and then comparisons of the information on each of them were carried out. 10 articles were selected. In conclusion, the presence of an aberrant anterior tibial artery is an anatomical alteration of low incidence, but it is responsible for complications during surgical procedures, due to its location close to the tibia. It is suggested to perform imaging tests for preoperative diagnosis of this anatomical abnormality.

ABSTRACT

Abstract The SAFARI technique or Subintimal Arterial Flossing with Antegrade-Retrograde Intervention is an endovascular procedure that allows recanalization of Chronic Total Occlusive (CTO) lesions when conventional subintimal angioplasty is unsuccessful. Retrograde access is usually obtained through the popliteal, anterior tibial, dorsalis pedis artery, or posterior tibial arteries and may potentially provide more options for endovascular interventions in limb salvage. The case of an 81-year-old man with a history of uncontrolled hypertension, diabetes mellitus, and dyslipidemia is presented. He presented with a cutaneous ulcer on the right lower limb with torpid evolution and poor healing. The Doppler ultrasound and arteriographic study revealed a CTO lesion of the popliteal artery that was not a candidate for antegrade endovascular revascularization, but was successfully treated using the SAFARI technique. The patient had no perioperative complications, the wound showed better healing, and he was discharged with an indication of daily dressings and control by an external outpatient clinic.


Resumo A técnica SAFARI, ou Subintimal Arterial Flossing with Antegrade-Retrograde Intervention, é um procedimento endovascular que permite a recanalização de lesões por oclusão total crônica (OTC) em caso de fracasso da angioplastia subintimal convencional. O acesso retrógrado é geralmente obtido através da artéria poplítea, tibial anterior, pediosa ou tibial posterior e pode fornecer mais alternativas de intervenções endovasculares para o salvamento do membro. É apresentado o caso de um homem de 81 anos com histórico de hipertenção não controlada, diabetes melito e dislipidemia. Ele apresentava uma lesão ulcerativa cutânea no membro inferior direito com evolução tórpida e má cicatrização. O ultrassom Doppler e o estudo arteriográfico revelaram uma lesão por OTC na artéria poplítea. O paciente não era candidato a revascularização endovascular anterógrada; sendo assim, esta foi realizada com successo utilizando a técnica SAFARI. O paciente não apresentou complicações perioperatórias e recebeu alta com indicação de cuidados diários com a ferida e controle em um ambulatório externo. Além disso, a ferida apresentou melhor cicatrização.

ABSTRACT

Abstract Moyamoya disease is a rare disorder that involves the cerebrovascular system. Usually, it leads to occlusion of the arteries of the cerebral system and causes cerebral circulatory complaints. A 48-year-old female patient was admitted to our clinic with intermittent claudication in both legs. Biphasic and monophasic waveform patterns were detected bilaterally in distal (trifurcation arteries) lower extremities with Doppler sonography. The patient therefore underwent systemic vascular examination. Computed tomography angiography revealed bilateral carotid occlusion at the level of supraclinoid segments, and opacifications were detected at the distal segments of the bilateral anterior cerebellar and middle cerebellar arteries. The patient was diagnosed with moyamoya disease, and anticoagulant treatment was started. In conclusion, most previous reports have presented the cerebrovascular involvement of moyamoya disease. However, this disease can involve different peripheral vascular systems and careful and systemic vascular examination is necessary for an exact diagnosis.


Resumo A doença de moyamoya é um distúrbio raro que envolve o sistema cerebrovascular. Normalmente, leva à oclusão das artérias do sistema cerebral e causa problemas circulatórios no cérebro. Uma mulher de 48 anos foi admitida em nossa clínica com claudicação intermitente em ambas as pernas. Na ultrassonografia com Doppler, foram detectados padrões de formato de onda bifásico e monofásico nas extremidades inferiores distais (artérias da trifurcação) de forma bilateral. Portanto, realizou-se o exame vascular sistêmico na paciente. A angiografia por tomografia computadorizada revelou oclusão carotídea bilateral no nível dos segmentos supraclinoides, e opacificações foram detectadas nos segmentos distais das artérias cerebelares anteriores e médias de forma bilateral. A paciente foi diagnosticada com doença de moyamoya, e o tratamento anticoagulante foi iniciado. Em conclusão, a maioria dos relatos anteriores apresentou o envolvimento cerebrovascular da doença de moyamoya. No entanto, essa doença pode envolver diferentes sistemas vasculares periféricos, e um exame vascular sistêmico minucioso é necessário para um diagnóstico exato.

ABSTRACT

Resumo A artéria poplítea é o principal local para a ocorrência de aneurismas periféricos. Suas formas de apresentação agudas são potencialmente ameaçadoras à viabilidade do membro e à vida, dentre as quais destacamos a sua rotura. Apesar de ser um evento raro, sua rotura demanda rápida proposta de intervenção para satisfatório desfecho terapêutico. O tratamento padrão-ouro é o cirúrgico convencional e se dá pela interposição de veia safena magna. Trabalhos feitos nas últimas décadas vêm encontrando associações entre a síndrome de Marfan e aneurismas periféricos. Este relato apresenta um caso de um aneurisma de artéria poplítea esquerda roto tratado com sucesso em um paciente de 82 anos diagnosticado clinicamente como portador de síndrome de Marfan previamente desconhecida.


Abstract The popliteal artery is the main site of occurrence of peripheral aneurysms. Acute presentations constitute a potential threat to limb viability and to life, especially in the event of rupture. Rupture is a rare event, but one that demands an immediate intervention decision to achieve a satisfactory treatment outcome. The gold standard treatment is conventional surgery, effecting repair by interposition of a great saphenous vein graft. Studies conducted in recent decades have found associations between Marfan Syndrome and peripheral aneurysms. This report presents a case of a ruptured left popliteal artery aneurysm successfully treated in an 82-year-old patient clinically diagnosed with previously unknown Marfan syndrome.

ABSTRACT

Los aneurismas de la arteria poplítea son los más frecuentes de todos los que afectan a las arterias periféricas y corresponde a un aumento del diámetro de esta arteria mayor de 1,5 cm. El diagnóstico fue de aneurisma de la arteria poplítea de ambos miembros inferiores, con mayor diámetro en la izquierda. Lo poco frecuente en este caso son las dimensiones que alcanzó la arteria poplítea izquierda. El paciente presentaba dolor en la fosa poplítea izquierda e imposibilidad de extensión de la pierna. Se detectó disminución importante de los índices de presiones dístales de ambos miembros inferiores y en la angiotomografía realizada al paciente se apreciaron dilataciones aneurismáticas trombosadas en ambas regiones poplíteas. Se realizó la aneurismectomía con sustitución protésica desde la arteria femoral superficial al tronco tibio-peroneo en el miembro inferior izquierdo. El paciente egresó con evolución satisfactoria(AU)


The popliteal artery´s aneurysms are the most frequent of all those that affect outlying arteries and it corresponds to an increase bigger than 1,5 cms of the diameter of this artery. A not very frequent case is presented due to the dimensions that the popliteal left artery reached. The case presented a diagnosis of aneurysm of the popliteal artery in both inferior limbs, with bigger diameter in the left which is infrequent. The patient presented pain in the left popliteal area and impossibility of extending the leg. Important decrease of the distal pressures indexes of both inferior limbs was detected, and in the performed angiotomography there was evidence of thrombosed aneurisms in both popliteal regions. The patient was attended in the operating room and an aneurismectomy with prosthesis substitution of femoral superficial artery to tibial- peroneal arterial trunk in left lower limb was carried out. The patient was discharged with satisfactory evolution(AU)

ABSTRACT

Objetivo: Evaluar y describir los resultados clínicos de la técnica Angioplastia de rescate en pacientes con isquemia crítica de miembros inferiores con enfermedad arterial infrapoplítea en un centro de atención nivel IV. Materiales y métodos: Estudio de cohorte ambispectivo analítico observacional. Resultados: Se realizaron angioplastias infrapoplíteas en el Servicio de Radiología de FOSCAL y FOSCAL Internacional entre septiembre de 2013 y abril de 2016, a 65 pacientes. Previo al procedimiento, en el 89 % de los pacientes se observó claudicación y dolor; en el 88 %, frialdad de la extremidad; en el 81 %, úlcera y en el 64 %, infección. En el 63 % de la población se encontraron tres síntomas asociados. Se dividieron los pacientes en dos grupos: el primero, aquellos a quienes se les había realizado angioplastia en un solo vaso y el segundo, a quienes se les había realizado angioplastia en dos o más vasos. Se encontró que el tiempo libre de amputación fue mayor en el grupo uno, comparado con el dos, con valor de P estadísticamente significativo. Conclusión: La angioplastia de vasos infrapoplíteos en pacientes con enfermedad arterial periférica (EAP) e isquemia crítica de miembros inferiores disminuye el dolor, la claudicación y la infección en los pacientes. Favorece una tasa baja de amputaciones mayores posteriores a la terapia como medida de salvamento de la extremidad. La probabilidad de supervivencia de la extremidad a los 573 días es del 50 %.


Objective: To evaluate and describe the clinical results of percutaneous transluminal angioplasty of critical limb ischemia in a level IV care center. Materials and methods: Observational analytical ambispective cohort study. Results: An infra-popliteal angioplasty was performed in the Radiology service of FOSCAL and FOSCAL International between the months of September 2013 and April 2016 to 65 patients. Prior to the procedure, 89% of the patients presented claudication and pain, 88% coldness of the limb, 81% of the patients presented ulceration and 64% infection, noting that 63% of the population had 3 associated symptoms. The patients were divided into two groups; the first, those who had undergone angioplasty in a single vessel and the second group who had undergone angioplasty in two or more vessels. We found that the amputation-free time was greater in the group one compared to group two, with a statistically significant P value. Conclusion: Angioplasty of infrapopliteal vessels in patients with peripheral arterial disease (PAD) and critical lower limb ischemia reduces pain, claudication and infection in patients. There is a low rate of major amputations after therapy as a measure of salvage of the limb. The probability of survival of the limb at 573 days is 50%.

ABSTRACT

ABSTRACT Objective: Identify the clinical and surgical complications associated with the use of a tourniquet in total knee arthroplasty in patients with or without calcification of the popliteal artery. Methods: The study was performed retrospectively, analyzing 58 patients with calcification of the popliteal artery and 57 patients as a control group. Results: The case group patients were significantly older than patients in the control group; however, this had no impact on the clinical outcome in the analyzed period.There were no complications during surgery in the groups studied, as there were no statistically significant differences between the incidence of local or systemic intercurrences in the analyzed period. Conclusion: This study found low rates of complications in patients undergoing total knee arthroplasties with use of a tourniquet, with or without calcification of the popliteal artery.


RESUMO Objetivo: Identificar as complicações clínicas e cirúrgicas associadas ao uso de torniquete na artroplastia total de joelho em pacientes com ou sem calcificação da artéria poplítea. Métodos: O estudo foi feito de modo retrospectivo, analisou 64 pacientes com calcificação da artéria poplítea e 57 pacientes como grupo controle. Resultados: Os pacientes do grupo de casos eram significativamente mais velhos do que os pacientes do grupo controle. Entretanto, tal fato não teve repercussão quanto ao desfecho clínico no período analisado. Não houve complicações durante o ato cirúrgico nos grupos estudados, bem como não houve diferenças estatisticamente significantes entre a incidência de intercorrências locais ou sistêmicas no período analisado. Conclusão: O presente estudo observou baixos índices de complicações em pacientes submetidos a artroplastia total do joelho com uso de torniquete com ou sem calcificação da artéria poplítea.

ABSTRACT

ABSTRACT Tibiofemoral unilateral knee dislocations are uncommon, making bilateral dislocations even rarer injuries. Knee dislocation is considered one of the most serious injuries that can affect this joint. Associated complications such as popliteal artery injury are responsible for the important morbidity in these patients. The authors report the case of a 52-year-old man with a traumatic bilateral knee dislocation with associated bilateral popliteal arterial injury. His clinical presentation along with radiographic and angiographic findings are described. Surgical and non-surgical treatment and functional outcomes are also reported.


RESUMO As luxações unilaterais tibiofemurais do joelho são incomuns, o que torna as luxações bilaterais ainda mais raras. A luxação do joelho é considerada um dos ferimentos mais graves nessa articulação. As complicações associadas, tais como a lesão da artéria poplítea, são responsáveis pela importante morbidade observada nesses pacientes. Os autores relatam o caso de um homem de 52 anos com luxação traumática bilateral do joelho associada a lesão bilateral da artéria políptea. O estudo descreve a apresentação clínica e os achados radiográficos e angiográficos. Os tratamentos cirúrgico e não cirúrgico e os resultados funcionais também são relatados.

ABSTRACT

Os aneurismas de artéria poplítea correspondem a 70% dos aneurismas periféricos e o tratamento é cirúrgico, com controvérsias sobre os resultados da via endovascular. Este estudo objetivou realizar uma revisão da literatura sobre a comparação entre cirurgia aberta e endovascular no tratamento dos aneurismas da artéria poplítea. A pesquisa foi realizada utilizando os termos apropriados nos portais de periódicos LILACS e MEDLINE, com a seleção de 15 artigos. Um total de 5.166 procedimentos cirúrgicos foram comparados, sendo 3.930 cirurgias abertas e 1.236 cirurgias endovasculares. A cirurgia aberta com bypass venoso continua sendo o padrão-ouro. A cirurgia endovascular apresenta menor tempo de internação e é uma opção viável em pacientes eletivos, com baixa expectativa de vida, alto risco cirúrgico, comorbidades e mais idosos, desde que tenham anatomia favorável para o procedimento. Contudo, são necessários estudos de longo prazo para estabelecer os reais benefícios e indicações das duas técnicas, como o ensaio clínico randomizado controlado


Popliteal artery aneurysms account for 70% of peripheral aneurysms and must be treated surgically. The results of endovascular treatment are controversial. The objective of this study is to conduct a literature review on comparisons between open surgery and endovascular treatment for popliteal artery aneurysms. Searches were run on the LILACS and MEDLINE databases using the appropriate search terms and 15 articles were selected. A total of 5,166 surgical procedures were compared, 3,930 open surgeries and 1,236 endovascular surgeries. Open surgery with venous bypass is still the gold standard. Endovascular surgery offers shorter length of hospital stay and is a viable option for elective patients, those with short life expectancy, high surgical risk, comorbidities, and more advanced age. However, long-term studies are needed to establish the true benefits and indications for the two techniques, such as randomized clinical trials

ABSTRACT

Las lesiones vasculares en cirugía artroscópica corresponden a menos del 1% de todas las complicaciones. En la reconstrucción del ligamento cruzado posterior, dada la relación anatómica existente entre el mismo y las estructuras neurovasculares de la región poplítea, el riesgo de lesión de la arteria poplítea es alto, aunque infrecuente según lo informado en la literatura médica. Dado la baja incidencia de esta complicación, pero su potencial gravedad, presentamos un caso de un pseudoanerurisma de la arteria poplítea luego de la reconstrucción artroscópica del ligamento cruzado posterior. Tipo de estudio: Reporte de caso. Nivel de evidencia: IV.


Vascular lesions in arthroscopic surgery correspond to less than 1% of all complications. In the reconstruction of the posterior cruciate ligament, given the anatomical relationship between it and the neurovascular structures of the popliteal region, the risk of injury to the popliteal artery is high but infrequent as reported in the medical literature. Given the low incidence of this complication, but its potential severity, we present a case of a pseudoanerurysm of the popliteal artery after the arthroscopic reconstruction of the posterior cruciate ligament. Type of study: Case report. Level of evidence: IV.

ABSTRACT

Introducción. La enfermedad arterial periférica es una patología de difícil diagnóstico dado que su manifestación, en general, es asintomática, hecho que condiciona el avance significativo en su historia natural y el diagnóstico en estadio avanzado en la mayoría de los casos. Su prevalencia varía entre 3 y 18, mayor que la percibida por los profesionales de la salud, así como sus repercusiones clínicas, sociales y económicas, convirtiéndola en un importante problema de salud. Materiales y métodos. Estudio de cohorte retrospectiva con pacientes llevados a procedimiento endovascular para manejo de obstrucciones arteriales en miembros inferiores entre febrero de 2010 y agosto de 2016, en el que se evaluó la nueva obstrucción arterial en un seguimiento a un año. Se realizó un análisis de supervivencia no paramétrico a través del método de Kaplan-Meier para describir la frecuencia (tasa de incidencia e incidencia acumulada) de nueva obstrucción arterial. Resultados. Ingresaron 102 pacientes de 183 llevados a angioplastia, con edad promedio de 70,7 años (DE: 9,6) y predominio del sexo masculino con 56 pacientes (54,9 %). Durante el primer año de seguimiento, 18 pacientes (17,7 %) presentaron reestenosis (tasa de incidencia de 19,9 eventos por cada 100 pacientes al año). El mayor periodo de reestenosis fueron los primeros 120 días del seguimiento, con posterior estabilidad y presentación de mayor tasa de reestenosis nuevamente en los últimos 120 días del seguimiento, y en pacientes con intervención mixta (supra e infragenicular). Conclusión. La incidencia de reestenosis al año fue del 17,7 %, con permeabilidad superior al 80 %. Los procedimientos endovasculares son una estrategia segura que ofrece resultados similares a los reportados en la literatura


Peripheral arterial disease is a pathology difficult to diagnose, since it mainly remains asymptomatic, which conditions the significant advance in its natural history and why at diagnosis it appears advanced in most patients. The prevalence of the disease has been determined in multiple studies, and varies from 3 to 18, higher than that perceived by health professionals, as well as its repercussions, both clinical, social, and economic. It constitutes a major health problem and remains an underestimated and underdiagnosed disease. Endovascular interventions of peripheral vascular pathologies are considered a fundamental treatment tool. However, there is no complete clarity regarding the patency time after endovascular interventions in the management of arterial occlusion, nor on methods that increase the degree of effectiveness of the procedure

ABSTRACT

Total knee arthroplasty has increased substantially, however anatomical studies of the genicular arteries (GAs) in this region are rare. The aim of this study was to identify the pattern and branching points of GAs and their relationship. In 42 lower limbs, the pattern and branching points of GAs were confirmed. The horizontal line which extends between the most prominent point of the lateral and medial margins of patella was defined as a reference line. The distance of branching point of the GAs from the reference line was measured, and the correlations between these points were analyzed. The superior lateral and medial genicular arteries (SLGA and SMGA) were located at + 38.17 ± 3.10 mm and + 32.68 ± 3.83 mm from the reference line, respectively. The middle genicular artery (MGA) was originated from + 7.57 ± 3.98 mm. The inferior lateral and medial genicular arteries (ILGA and IMGA) were located at - 18.46 ± 2.63 mm and - 24.09 ± 3.52 mm, respectively. The branching points of the SLGA changed significantly according to the arterial branching pattern with the MGA. In addition, the branching point of the MGA had positive relationships with that of the IMGA (r = 0.385, p <0.05) and that of the ILGA (r = 0.348, p <0.05), respectively. In this study, topography of the GAs and its anatomical association were demonstrated for the first time in Korean cadavers. Knowledge of the topography about frequent variation would be useful for safe surgery and clinical procedures.


La artroplastía total de rodilla ha aumentado sustancialmente, sin embargo los estudios anatómicos de las arterias geniculares (AGs) en esta región son escasos. El objetivo de este estudio fue identificar los patrones y puntos de ramificación de las AGs y sus relaciones. En 42 miembros inferiores, se identificaron el patrón y los puntos de ramificación de las AGs. La línea horizontal que se extiende entre el punto más prominente de los márgenes lateral y medial de la patela se definió como una línea de referencia. Se midió la distancia entre el punto de ramificación de las AGs y la línea de referencia, y se analizaron las correlaciones entre estos puntos. Las arterias geniculares superiores lateral y medial (AGSL y AGSM, respectivamente) se situaron a + 38,17 ± 3,10 mm y + 32,68 ± 3,83 mm de la línea de referencia, respectivamente, y la arteria genicular media (AGM) se originó a partir de + 7,57 ± 3,98 mm. Las arterias geniculares inferiores lateral y medial (AGIL e AGIM, respectivamente) se localizaron a - 18,46 ± 2,63 mm y - 24,09 ± 3,52 mm, respectivamente. Los puntos de ramificación de la AGSL cambiaron significativamente de acuerdo con el patrón de ramificación arterial con respecto a la AGSM. Además, el punto de ramificación de la AGSM tuvo relaciones positivas con el de la AGIM (r = 0.385, p <0.05) y el de la AGIL (r = 0.348, p <0.05). En este estudio, la topografía de las AGs y su asociación anatómica se demostraron por primera vez en cadáveres coreanos. El conocimiento de la topografía sobre la variación frecuente sería útil para su aplicación en el desarrollo de cirugías y procedimientos clínicos seguros.

ABSTRACT

La enfermedad quística de la adventicia es una rara alteración de las arterias periféricas, caracterizada por la acumulación de contenido mucoso en la adventicia del vaso. Tiene predilección por la arteria poplítea, donde se localiza en cerca de 85 % de los casos. La mayoría de los afectados son hombres entre los 40 y los 50 años de edad, que presentan claudicación intermitente de inicio brusco y rápida progresión, sin evidencia de enfermedad ateroesclerótica. Se describe el caso un hombre de 57 años de edad en el que se diagnosticó esta entidad, con énfasis en las imágenes diagnósticas y el abordaje quirúrgico


Cystic adventitial disease is a rare vascular disorder of the peripheral arteries characterized by the collection of a mucinous substance inside the adventitia of the vessel. It has a predilection for the popliteal artery, being this localization about 85% of cases. Most of those affected are male between 40 to 50 years old, presenting with intermittent claudication of sudden onset and rapid progression without evidence of atherosclerotic disease. We describe the case of a 57 years old male who was diagnosed with this entity, with emphasis on the diagnostic imaging and surgical approach

ABSTRACT

Abstract The posterior tibial artery normally arises from tibial-fibular trunk at the popliteal fossa, together with the fibular artery. The classic course of the posterior tibial artery is to run between the triceps surae muscle and muscles of the posterior compartment of the leg before continuing its course posteriorly to the medial malleolus, while the fibular artery runs through the lateral margin of the leg. Studies of both arteries are relevant to the fields of angiology, vascular surgery and plastic surgery. To the best of our knowledge, we report the first case of an anastomosis between the posterior tibial artery and the fibular artery in their distal course. The two arteries joined in an unusual “X” format, before division of the posterior tibial artery into plantar branches. We also provide a literature review of unusual variations and assess the clinical and embryological aspects of both arteries in order to contribute to further investigations regarding these vessels.


Resumo A artéria tibial posterior e a artéria fibular se originam do tronco tibiofibular, na fossa poplítea. A trajetória clássica da artéria tibial posterior é correr entre o tríceps sural e os músculos do compartimento posterior da perna, e, então, seguir posteriormente ao maléolo medial. Já a artéria fibular corre na margem lateral da perna, seguindo profundamente aos músculos. O estudo dessas artérias é relevante para o campo da angiologia, cirurgia vascular e cirurgia plástica. O presente trabalho é o primeiro relato de caso de uma anastomose entre ambas artérias, na porção distal de suas trajetórias. Tais artérias se anastomosaram em formato de “X”, antes da divisão da artéria tibial posterior em ramos plantares. Foi feita uma revisão de literatura das variações de tais artérias, dando ênfase ao aspecto clínico e embriológico, de modo a contribuir para novas investigações sobre esses vasos.
