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

Popliteal artery aneurysms is the most frequent peripheral aneurysm, predominantly affects men over 60 years of age and has a high morbidity associated to his complications, among which are ischemic complication, which can often end in amputation of the limb. Less frequent complications such as neuropathic and venous complications, particularly deep vein thrombosis, are equally relevant. Case presentation: Patient with an aneurysm of the popliteal artery complicated by thrombosis of the adjacent popliteal vein. Color Doppler ultrasound plays a fundamental role in the diagnosis.

ABSTRACT

Introducción: La indicación más clara de revascularización en las extremidades inferiores lo constituye la presencia de lesiones isquémicas y el tratamiento de elección, siempre que sea posible, es el endovascular debido a su buena permeabilidad, baja morbilidad y mortalidad. Objetivo: Presentar un caso en el que se utilizó la angioplastia transluminal percutánea del sector fémoro-poplíteo. Presentación del caso: Se presenta un caso con diagnóstico de enfermedad arterial periférica en la extremidad inferior derecha. La angioplastia transluminal percutánea se utilizó para cicatrizar lesiones isquémicas aún en presencia de oclusiones no revascularizables de las arterias infra-poplíteas. El paciente presentaba al examen físico lesión isquémica en el primer dedo y patrón esteno-oclusivo fémoro-poplíteo. Se detectó disminución de los índices de presiones en poplítea y distales. En la arteriografía se apreciaron lesiones esteno-oclusivas en la femoral superficial y oclusión de las arterias infra-poplíteas. Se realizó angioplastia transluminal percutánea de la femoral superficial y el paciente recuperó pulso poplíteo con mejoría hemodinámica. Evolucionó satisfactoriamente y egresó con tratamiento médico. A los cinco meses de operado mantiene su pulso poplíteo presente y la lesión cicatrizada. Conclusión: La angioplastia del sector fémoro-poplíteo es beneficiosa para la cicatrización de la lesión isquémica aún en presencia de oclusiones infra-poplíteas no revascularizables(AU)


Introduction: The clearest indication for revascularization in lower limbs is the presence of ischemic lesions. The treatment of choice, whenever possible, is the endovascular one, due to its good permeability, as well as low morbidity and mortality. Objective: To present a case in which percutaneous transluminal angioplasty of the femoro-popliteal sector. Case presentation: A case is presented with a diagnosis of peripheral arterial disease in the right lower limb. The percutaneous transluminal angioplastywas used to heal ischemic lesions even in the presence of nonrevascularizable occlusions of the infra-popliteal arteries. On physical examination, the patient presented an ischemic lesion on the first finger and a femoro-popliteal steno-occlusive pattern. Decrease in pressure indices was detected in the popliteal and the distal ones. Arteriography showed steno-occlusive lesions in the superficial femoral and occlusion of the infra-popliteal arteries. Percutaneous transluminal angioplasty of the superficial femoral artery was performed and the patient recovered the popliteal pulse with hemodynamic improvement. The patient evolved satisfactorily and was discharged with medical treatment. Five months after surgery, the patient maintains popliteal pulse and the lesion has cicatrized. Conclusion: Angioplasty of the femoro-popliteal sector prove beneficial for the healing of the ischemic lesion even in the presence of nonrevascularizable infra-popliteal occlusions(AU)

ABSTRACT

ABSTRACT Endovascular treatment for femoropopliteal arterial disease has made revascularization procedures less invasive, but the self-expanding stents used can suffer great wear in arteries with extreme mobility. Objective: to evaluate the prevalence of fractures in stents implanted in the femoropopliteal segment, to identify predisposing factors and consequences on arterial patency. Method: between March and June 2019, thirty patients previously operated for femoropopliteal obstruction underwent stent X-rays in anteroposterior and lateral views to detect fractures and Doppler to analyze arterial patency. Results: we observed 12 cases with fractures (33.3%): 1 type I (2.8%), 3 type II (8.3%), 5 type III (13.9%), 3 type IV (8.3%) and no type V. According to the TASC II we had 1 in group B (8.3%), 6 in group C (50%) and 5 in group D (41.6%) p <0.004. The number of stents per limb was 3.1 (± 1.3) in cases of fracture versus 2.3 (± 1.3) in cases without fracture (p = 0.08). The extension was 274.17mm (± 100.94) in cases of fracture and 230.83mm (± 135.44) in cases without fracture (p = 0.29). On Doppler we had: 17 patients (47.2%) without stenosis, 9 patients (25%) with stenosis> 50% and 10 patients (27.8%) with occlusion (p = 0.37). There was no correlation between fracture and arterial obstruction (p = 0.33). Conclusion: stent fractures are a frequent finding in the femoropopliteal area (33.3%), being more prevalent in cases of more advanced disease (C and D). There was no association between the finding of fracture and arterial obstruction.


RESUMO Os tratamentos endovasculares para a doença arterial obstrutiva fêmoro-poplítea tornaram os procedimentos de revascularização menos invasivos, porém os stents metálicos autoexpansíveis utilizados podem sofrer grande desgaste em artérias com extrema mobilidade. Objetivo: avaliar a prevalência de fraturas em stents implantados no segmento fêmoro-poplíteo, identificar fatores predisponentes e possíveis consequências sobre a patência arterial. Métodos: entre março a junho de 2019, trinta pacientes previamente operados por obstrução fêmoro-poplítea realizaram RX dos stents em incidências ântero-posterior e perfil para detectar fraturas e eco Doppler para analisar a patência arterial. Resultados: observamos 12 casos com fraturas (33,3%): 1 do tipo I (2,8%), 3 do tipo II (8,3%), 5 do tipo III (13,9%), 3 do tipo IV (8,3%) e nenhuma tipo V. Segundo a classificação TASC II, tivemos 1 no grupo B (8,3%), 6 no grupo C (50%) e 5 no grupo D (41,6%) p<0,004. O número de stents por membro foi de 3,1 (±1,3) nos casos de fratura contra 2,3 (±1,3) nos casos sem fratura (p = 0,08). A extensão tratada foi 274,17mm (±100,94) nos casos de fratura e 230,83mm (±135,44) nos casos sem fratura (p=0,29). No Doppler tivemos: 17 pacientes (47,2%) sem estenose, 9 pacientes (25%) com estenose>50% e 10 pacientes (27,8%) com oclusão (p=0,37). Não houve correlação entre fratura e obstrução arterial (p=0,33). Conclusão: as fraturas de stents são um achado frequente no setor fêmoro-poplíteo (33,3%) sendo mais prevalentes nos casos de doença mais avançada TASC II C e D. Não houve associação entre o achado de fratura e obstrução arterial.

ABSTRACT

ABSTRACT The present study aimed to evaluate the acute behavior of the brachial artery resistance index (BARI) and popliteal artery resistance index (PARI) in response to low intensity strength exercises involving small (SMG) and large muscle groups (LMG) performed with and without blood flow restriction. Eleven men (age 23 ± 3.29 years) underwent a four-arm, randomized, cross-over experiment: Small muscle group exercise (SMG), small muscle groups with blood flow restriction (SMG+BFR), large muscle groups (LMG) and large muscle groups with blood flow restriction (LMG+BFR). The behavior of BARI and PARI was evaluated at rest, immediately after exercise, and at 15 and 30 minutes during recovery. Data analysis showed a significant reduction of the BARI from rest to post-exercise only in the protocols involving SMG, regardless of the BFR (p <0.05). Protocols involving LMG, with or without BFR, did not affect PARI (p> 0.05), but were efficient to promote significant increases in BARI (p <0.05) immediately after exercise. Our findings indicate that the exercises involving SMG, regardless of BFR, are efficient to promote local vasodilatation (brachial artery), but without systemic effects. None of the analyzed protocols affected the PARI behavior.


RESUMO O presente estudo objetivou avaliar o comportamento agudo do índice de resistência da artéria braquial (IRAB) e da artéria poplítea (IRAP) em resposta a exercícios de força de baixa intensidade envolvendo pequenos (PGM) e grandes grupos musculares (GGM), realizado com e sem restrição de fluxo sanguíneo. Onze homens (idade 23 ± 3,29 anos) realizaram um experimento randomizado, cruzado, com quatro braços: Exercício para pequenos grupos musculares (PGM), pequenos grupos musculares com restrição de fluxo sanguíneo (PGM+RFS), grandes grupos musculares (GGM) e grandes grupos musculares com restrição de fluxo sanguíneo (GGM+RFS). O comportamento de IRAB e IRAP foi avaliado em repouso, mediatamente após o exercício, e aos 15 e 30 minutos da recuperação. A análise dos dados mostrou uma redução significativa do IRAB do repouso para o pós-exercício apenas nos protocolos de PGM com ou sem RFS (p <0,05). Protocolos envolvendo GGM, independentemente do BFR, não afetaram o IRAP (p> 0,05), porém, foram eficientes para promover aumentos significativos do IRAB (p <0,05) imediatamente após o exercício. Nossos achados indicam que os exercícios envolvendo PGM, independentemente da BFR, são capazes de promover a vasodilatação local (artéria braquial), porém, sem efeitos sistêmicos. Nenhum dos protocolos analisados afetou o comportamento do IRAP.

ABSTRACT

Adventitial cystic disease of the popliteal artery is a rare condition of uncertain etiology, which presents as intermittent claudication of the lower extremity in middle-age patients. We report a 44-year-old man presenting with intermittent claudication of his left leg. MR angiography showed cystic parietal lesions that caused compression with partial occlusion of the left popliteal artery. Surgical resection of the affected segment was performed, with venous graft interposition. The histopathological analysis of the surgical specimen was consistent with cystic adventitial disease.

ABSTRACT

O stent primário é uma opção de tratamento bem estabelecida para a doença arterial periférica em território femoropoplíteo. Estudos nacionais são escassos. Objetivos Avaliar desfechos clínicos e radiológicos em curto e médio prazo em pacientes classificados como Rutherford 3-6, tratados com o uso de stent em lesões femoropoplíteas. Métodos A análise foi realizada com base em um banco de dados prospectivamente mantido de doentes tratados entre julho de 2012 e julho de 2015. O objetivo primário foi a perviedade. Os objetivos secundários foram melhora na classificação de Rutherford, índice tornozelo/braço, revascularização do vaso-alvo, taxa de salvamento do membro e óbito em até 24 meses. Resultados Foram incluídos 64 pacientes, sendo 61 com lesões TASC II A/B (95%). A taxa de perviedade primária em 6, 12 e 24 meses foi de 95,2%, 79,1% e 57,9%, respectivamente. A análise de regressão de Cox revelou uma menor perviedade em pacientes com doença oclusiva (RR, 6,64, IC 95%, 1,52-28,99, p = 0,02), bem como uma perda de perviedade cerca de seis vezes maior em doentes TASC B do que TASC A (RR, 5,95, IC 95%, 1,67-21,3, p = 0,0061). Em 12 meses, 90,38% dos doentes permaneceram assintomáticos. A taxa de salvamento do membro em 24 meses foi de 94,3% (IC 95%, 87,9-100%). A ausência de revascularização do vaso-alvo em 24 meses foi de 90,5% (IC 95%, 82,8-98,9%). Conclusões Os resultados foram compatíveis com estudos internacionais, apesar do estágio mais avançado da doença vascular observada em nosso grupo. Piores desfechos foram associados a doença oclusiva e lesões complexas


Primary stenting is a well-established treatment option for femoropopliteal arterial obstructive disease. There is a shortage of Brazilian studies of the subject. Objectives To evaluate short and mid-term clinical and radiological outcomes in patients classified as Rutherford 3-6 and treated with stenting of femoropopliteal lesions. Methods Analysis based on a prospectively populated database of patients treated from July 2012 to July 2015. The primary endpoint was primary patency. Secondary endpoints were clinical and ankle/brachial index changes. Target Vessel Revascularization, limb salvage rate and death, within a 24-month follow-up period. Results 64 patients were enrolled, including 61 TASC II A / B lesions (95%). The primary patency rates at 6, 12, and 24 months were 95.2%, 79.1% and 57.9%, respectively. Cox regression analysis revealed lower patency rates in patients with occlusive disease (hazard ratio [HR], 6.64; 95% confidence interval [CI], 1.52-28,99, p = 0.02), as well as patency loss about 6 times higher in TASC B than in TASC A patients ([HR], 5.95, 95% CI, 1.67-21.3, p = 0.0061). At 12 months, 90.38% of the patients remained asymptomatic. The limb salvage rate at 24 months was 94.3% (95% CI, 87.9-100%). Freedom from TVR at 24 months was 90.5% (95% CI 82.8-98.9%). Conclusions Results of primary patency were compatible with international studies, despite the more advanced stage of the vascular disease observed in our group. Occlusive disease and complex lesions were both associated with worse outcomes

ABSTRACT

A 58-year-old male patient with severe claudication due to thrombosis of the left ilio-femoro-popliteal artery aneurysm. He also had a venous stasis ulcer with a history of multiple embolotherapy of arteriovenous malformation. Duplex sonography revealed reflux and varicose veins of the left great saphenous vein (GSV). A sequential bypass surgery was performed that consisted of excision of the left external iliac and common femoral artery aneurysm, external iliac to deep femoral interposition with an expanded polytetrafluoroethylene graft, and femoro-posterior tibial artery bypass with the reversed left GSV. Symptoms of claudication were alleviated and the chronic ulcer was healed in time. To our knowledge, this is the first report of successful bypass in a patient with arterial aneurysm, arteriovenous malformation, and venous insufficiency that can be diagnosed as an atypical case of Parkes Weber syndrome. Long-term follow-up is needed to define the fate of aneurysms and varicose vein graft.

ABSTRACT

PURPOSE: The clinical characteristics and results of femoropopliteal artery injury (FPAI) remain unclear. In this study, we evaluated the outcomes and risk factors of limb loss in patients treated for FPAI. MATERIALS AND METHODS: We retrospectively reviewed data from a database of patients who underwent revascularization for an FPAI at a single institution between January 2013 and December 2017. We reviewed and analyzed the characteristics, postoperative results, and factors that influence amputation rates. RESULTS: Twenty-four femoropopliteal arterial reconstructions in 24 patients were included in this study. Among the patients were 20 (83.3%) male with a first-quartile age of 28 years and a third-quartile age of 45 years (range, 15–68 years). The mean injury severity score (ISS) was 16 (range, 4–55), and 5 patients (20.8%) had ISSs of >20 points. The mean mangled extremity severity score (MESS) was 3.8 (range, 1–11), and 8 patients (33.3%) had MESSs of >5 points. In terms of arterial reconstruction methods, autogenous saphenous vein grafting, vein patching, and primary closure were performed in 9 patients (37.5%), 4 patients (16.7%), and 11 patients (45.8%), respectively. Despite arterial reconstruction, 5 patients (20.8%) underwent above-knee amputation. ISSs of >20, MESSs of >7, and orthopedic fixation were statistically significant factors associated with amputation. CONCLUSION: In cases of FPAI with ISSs of >20, MESSs of >7, and orthopedic fixation, amputations should be considered. We were also careful to attempt limb salvage in such cases.

ABSTRACT

Giant popliteal artery aneurysm is an uncommon entity. If untreated, it results in life-threatening complications. It is usually seen in older patients (over 60 years of age), and atherosclerotic disease is its main cause. Few cases have been reported in young adults, and its incidence in teenagers is exceptionally rare, with scarce case reports in the literature. We report a case of left popliteal artery aneurysm in a 16-year-old and its successful surgical treatment through resection and repair with a synthetic interposition graft.

ABSTRACT

BACKGROUND: This study aimed to determine the optimal location of local anesthetic injection in the interspace between the popliteal artery and posterior capsule of the knee (iPACK), using the anatomical pattern of the articular branch of tibial nerve (ABTN). We hypothesized that injection at the level of ABTN forming a popliteal plexus would mainly spread throughout the popliteal fossa without contacting the tibial or peroneal nerves. METHODS: The anatomical study included 30 soft cadavers. Ultrasound-guided dye injection was performed in legs of 10 cadavers after identifying the position of the ABTN and surrounding structures, followed by dissection to assess its spread. Clinical study was conducted in 15 patients undergoing total knee arthroplasty (TKA) with ultrasound-guided injection in the iPACK. All patients also received continuous adductor canal block. Sensorimotor function of the tibial and common peroneal nerves was determined. RESULTS: In the distal portion of the popliteal fossa, the tibial nerve and popliteal vessels ran superficially and closely together. The trajectory of ABTN ran lateral to the popliteal vasculature, forming a plexus towards the posterior capsule of the knee below the medial side of the upper edge of lateral femoral condyle. In cadavers, the ABTN and surrounding area of the popliteal plexus were stained with dye after injection. In the clinical study, no patients experienced complete motor or sensory blocks. CONCLUSIONS: We described a modified iPACK technique injection at the level of the ABTN forming the popliteal plexus, and it may constitute an optional anesthetic regimen to promote early ambulation following TKA.

ABSTRACT

BACKGROUND: The Infiltration between the Popliteal Artery and Capsule of the Knee (IPACK) block is a new anesthesiologist- administered analgesic technique for controlling posterior knee pain that has not yet been well studied in total knee arthroplasty (TKA) patients. We compared pain outcomes in TKA patients before and after implementation of the IPACK with the hypothesis that patients receiving IPACK blocks will report lower pain scores on postoperative day (POD) 0 than non-IPACK patients. METHODS: With Institutional Review Board approval, we retrospectively reviewed data for consecutive TKA patients by a single surgeon 4 months before (PRE) and after (POST) IPACK implementation. All TKA patients received adductor canal catheters and peri-operative multimodal analgesia. The primary outcome was pain on POD 0. Other outcomes were daily pain scores, opioid consumption, ambulation distance, length of stay, and adverse events within 30 days. RESULTS: Post-implementation, 48/50 (96%) of TKA patients received an IPACK block, and they were compared with 32 patients in the PRE group. On POD 0, the lowest pain score (median [10th–90th percentiles]) was significantly lower for the POST group compared to the PRE group (0 [0–4.3] vs. 2.5 [0–7]; P = 0.003). The highest patient-reported pain scores on any POD were similar between groups with no differences in other outcomes. CONCLUSIONS: Within a multimodal analgesic protocol, addition of IPACK blocks decreased the lowest pain scores on POD 0. Although other outcomes were unchanged, there may be a role for new opioid-sparing analgesic techniques, and changing clinical practice change can occur rapidly.

ABSTRACT

Atherosclerosis-related diseases have increasingly become health concerns with the increased living conditions and aging.Globally,about 200 million people have suffered from arteriosclerosis obliterans(ASO),which can even be life-threatening in some cases.The past seven decades have witnessed the rapid advances in the treatment of ASO,which has developed from surgery to endovascular interventions including plain balloon angioplasty,bare metal stent placement,drug-coated balloon,and drug-eluting stent.However,the roles of these new techniques for femoral-popliteal lesions,especially their real-world clinical outcomes and indications,remain unclear.This article reviews the latest evidences on the use of drug-eluting devices in treating femoral-popliteal arteriosclerosis obliterans.

ABSTRACT

INTRODUCCIÓN: La luxación expuesta de rodilla es compleja, de incidencia baja con grandes secuelas funcionales. Existen escasos reportes de series en la literatura relativos a su manejo y resultados. OBJETIVO: El objetivo de este trabajo fue describir los resultados obtenidos de todos los pacientes con luxación expuesta de rodilla tratados durante las últimas dos décadas en nuestro hospital bajo un mismo estándar de tratamiento. MÉTODO: Estudio descriptivo retrospectivo en una serie quirúrgica de 11 pacientes con luxación expuesta de rodilla, tratados entre 1994 y 2015. Todos fueron estudiados y manejados según esquema estandarizado: Angiografía/ angioTC, aseo quirúrgico, fijador externo y reparación neurovascular en casos necesarios. Revisión de registros clínicos e imagenológicos consignando datos demográficos, lesiones concomitantes, número y tipo de cirugías, y complicaciones asociadas. Seguimiento promedio fue de 10,7 años con evaluación mediante encuesta funcionales SF-12/IKDC durante el mes de marzo de 2015. RESULTADOS: Diez pacientes eran hombres, 1 mujeres. Edad promedio al accidente 38,6 años. Mecanismo lesional de alta energía; como referencia la clasificación de Schenck, 1 lesión III-M, 4 tipo IV y los 6 restantes una tipo V. 4 lesiones vasculares (36.4%) y 7 lesiones neurológicas (63.6%). Tratamiento definitivo consistió en 4 reconstrucciones ligamentarias, 2 prótesis, 3 artrodesis y 2 amputaciones supracondíleas. Evaluaciones funcionales dieron como resultados un puntaje promedio de 37 y 48,5 para SF-12 físico y mental respectivamente, y de 44,1 para IKDC. CONCLUSIÓN: La luxación expuesta de rodilla es una lesión infrecuente, muy compleja, asociada a accidentes de alta energía, con complicaciones severas, lo que determina resultados funcionales relativamente malos. La estandarización permite sistematizar las distintas etapas de atención, racionalizar los recursos disponibles evitando la improvisación en momentos críticos, lo que podría incidir en la obtención de resultados.


INTRODUCTION: Open knee dislocation is a complex lesion of low incidence and large functional sequelae. There are few series reports in the literature regarding its management and outcomes. OBJECTIVE: Describe the results obtained from all patients with open knee dislocation treated during the last two decades in our hospital under the same treatment standard. METHOD: Retrospective descriptive study in a surgical series of 11 patients with open knee dislocation, treated between 1994 and 2015. All were studied and managed according to a standardized protocol: Angiography/angioCT, surgical debridement, external fixation and neurovascular repair in necessary cases. Review of clinical and imaging records, recording demographic data, concomitant injuries, number and type of surgeries and associated complications. Average follow-up was 10.7 years, with an evaluation through functional surveys SF-12/IKDC during March 2015. RESULTS: 10 patients were men, 1 woman. Average age at accident 38.6 years. High-energy trauma mechanism of injury; Schenk classification as reference, 1 lesion type III-M, 4 type IV and the remaining 6 type V. 4 vascular lesions (41.7%) and 7 neurological lesions (63.6%). Definitive treatment consisted in 4 ligamentous reconstructions, 2 prostheses, 3 arthrodesis and 3 supracondylar amputations. Functional evaluations showed an average score of 37 and 48.5 for SF-12 physical and mental respectively, and 44.1 for IKDC. CONCLUSION: Open knee dislocation is a rare, very complex, associated to high-energy trauma, with severe complications, which determines relatively poor functional outcomes. Standardization allows to systematize the different stages of attention and rationalize available resources avoiding improvisation at critical moments, which could affect the results.

ABSTRACT

A fístula arteriovenosa (FAV) é uma comunicação anormal e permanente entre uma artéria e uma veia devido a traumas penetrantes e lesões iatrogênicas. O trauma penetrante na parede arterial pode levar à formação de pseudoaneurismas (PSA) e, se houver lesão venosa concomitante, à formação de uma FAV. Os autores apresentam o caso de um paciente portador de FAV complexa de vasos poplíteos associada a pseudoaneurisma de artéria poplítea, sugeridos a partir de exames clínicos e exames de imagem, e tratados por cirurgia convencional devido à indisponibilidade de um stent graft com diâmetro apropriado, além de a cirurgia endovascular não estar disponível no serviço em que o paciente foi operado


An arteriovenous fistula (AVF) is an abnormal and permanent communication between an artery and a vein caused by penetrating traumas or iatrogenic injuries. A penetrating trauma to the endothelial wall can lead to formation of pseudoaneurysms (PSA) and to formation of an AVF. Here, the authors present the case of a patient with a complex AVF of popliteal vessels, associated with popliteal artery pseudoaneurysm, suggested by clinical features and imaging exams, and treated with conventional surgery due to unavailability of a stent graft with appropriate diameter and because endovascular surgery isn't provided at the service where this patient was operated

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

A doença cística adventicial da artéria poplítea é uma doença pouco frequente, que deve ser considerada no diagnóstico diferencial de pacientes jovens com claudicação intermitente e sem fatores de risco para doença arterial periférica aterosclerótica. Apresentamos um caso de claudicação intermitente de membros inferiores em paciente masculino de 51 anos no qual essa doença foi diagnosticada. Foi submetido a ressecção do segmento de artéria comprometido e interposição de safena autóloga ipsilateral. Discutimos alternativas diagnósticas e terapêuticas


Adventitial cystic disease of the popliteal artery is an uncommon pathology that should be considered in differential diagnostic of younger patients with intermittent claudication and without risk factors for peripheral atherosclerotic arterial disease. We report the case of a 51 year-old male patient presenting with lower-limb intermittent claudication in whom this pathology was diagnosed and who was treated with segmental arterial resection and autologous saphenous vein interposition. We also discuss diagnostic and therapeutic alternatives

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

O tratamento convencional do aneurisma da artéria poplítea é a cirurgia aberta de exclusão do aneurisma e revascularização do membro acometido. Nos últimos anos, o tratamento endovascular vem ganhando popularidade e interesse. O tratamento endovascular é menos invasivo e de menor morbidade; porém, é de alto custo e sua perviedade é incerta. O objetivo desta revisão é comparar os dois tratamentos através da análise de desfechos abordados em estudos primários e secundários. Realizou-se uma revisão narrativa da literatura publicada nos últimos 5 anos. Foram selecionados seis estudos retrospectivos, duas metanálises, um ensaio clínico e uma revisão sistemática Cochrane. Número limitado de pacientes e curto período de seguimento não nos permitem extrair conclusões consistentes. Não há evidência clara que sugere melhores resultados entre um ou outro tratamento eletivo. Novos ensaios randomizados devem ser realizados para determinar o papel do tratamento endovascular desse aneurisma


he conventional treatment for a popliteal artery aneurysm is open surgery to exclude the aneurysm and revascularization of the affected limb. Over recent years, endovascular treatment has grown in popularity and has been attracting increased interest. Endovascular treatment is less invasive and associated with lower rates of morbidity, but it is expensive and patency is uncertain. The aim of this review is to compare these two treatments by analyzing the outcomes reported in primary and secondary studies. A narrative review is conducted of the literature published over the last 5 years. Six retrospective studies, two meta-analyses, one clinical trial and one Cochrane systematic review were selected. We were unable to draw firm conclusions because of small patient samples and short follow-up periods. There is no clear evidence to indicate that the outcomes of one or another elective treatment are superior. New randomized trials should be conducted to determine the role endovascular treatment has to play in management of this type of aneurysm

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.
