ABSTRACT

Objective: To analyze the treatment and clinical prognosis of lower extremity arterial injury caused by trauma. Methods: The clinical data of 77 patients with traumatic lower extremity arterial injury admitted to Department of Vascular Surgery,Yichang Central People's Hospital from January 2013 to June 2021 were collected retrospectively. There were 65 males and 12 females, with an average age of 47.4 years (range: 7 to 75 years). Among the 77 patients, 56 cases (72.7%) had open injury and 21 cases (27.3%) had closed injury. Iliac artery was injured in 9 cases (11.7%), common femoral artery in 7 cases (9.1%), superficial femoral artery in 1 case (1.3%), popliteal artery in 11 cases (14.3%) and inferior knee artery in 49 cases (63.6%). The treatment methods and clinical effects were analyzed. Results: One case with pelvic fracture combined the internal iliac artery injury and 1 case with multiple injuries involving the common femoral artery died of circulatory failure before surgery. Seventy-five cases received vascular-related operations, including arterial ligation in 24 cases, arterial reconstruction in 40 cases, stent graft implantation in 1 case, primary amputation in 2 cases, and arterial embolization in 8 cases. The overall mortality rate was 6.5% (5/77), all of which were closed injuries. Except for 2 cases who died before surgery, 3 cases with pelvic fracture combined the internal iliac artery injury died of multiple organ failure after internal iliac artery embolization. There were 8 cases received amputation (10.4%, 8/77), 5 cases with closed injury and 3 cases with open injury. In addition to 2 cases with primary amputation, 6 cases underwent secondary amputation due to ischemia-reperfusion injury after revascularization (4 cases with popliteal artery injury and 2 cases with subpatellar artery injury). The average followed-up time was 17 months (range: 2 months to 8 years). One patient with femoral artery injury underwent autologous great saphenous vein bypass, and lower limb artery CT angiography was re-examined 6 months after the operation, and 30% distal anastomotic stenosis was found. Ankle brachial index<0.8 was found in two patients 1 year after popliteal artery repair, but none of the patients had intermittent claudication symptoms, and no further intervention was performed. Five patients suffered delayed healing due to severe lower limb injury, fracture and skin injury. Among them, 2 cases had poor wound healing at the stump of amputation, which gradually healed 3 to 5 months after several debridements. The other 3 vascular injury combined with tibial fracture patients had delayed tibial healing after surgery, but no symptoms of vascular ischemia occurred. All the other patients recovered well and no other serious complications occurred. Conclusions: The proportion of death and disability in patients with lower limb artery injury caused by trauma is high. Active and orderly surgical repair according to the site and type of injury can reduce the mortality, save the function of the affected limb, and promote the healing of injury.

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

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

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

Abstract Vascular bypass is a surgical procedure widely used to treat peripheral vascular disease. The intraoperative anesthetic technique and the most appropriate postoperative analgesia for these high-risk patients remain controversial. We present the case of a patient undergoing femoropopliteal-distal bypass in our service, presenting with relevant comorbidities to the choice of anesthetic technique. This patient had several determining factors of difficult airway, especially thoracic kyphoscoliosis, which prevented him from being properly positioned for airway management, and chronic lung disease. This patient was also taken antiplatelet drugs, which is a contraindication for neuraxial block. So, we chose the anesthetic technique of peripheral nerve block, specifically the blockade of femoral and sciatic nerves.


Resumo A cirurgia para bypass vascular é um procedimento amplamente usado para o tratamento da insuficiência vascular periférica. A técnica anestésica para o intraoperatório e para analgesia pós-operatória mais apropriada para esses pacientes de alto risco ainda permanece controversa. Apresentaremos o caso de um paciente submetido a bypass femoropoplíteo distal no nosso serviço, que apresentava comorbidades relevantes para a escolha da técnica anestésica. Esse paciente apresentava fatores determinantes de via aérea difícil, principalmente cifoescoliose da coluna torácica, que o impedia de ser posicionado adequadamente para o manejo da via aérea, além de ser portador de patologia pulmonar crônica. Também fazia uso de antiplaquetários que contraindicavam o bloqueio de neuroeixo. Por isso, optou-se como técnica anestésica pelo bloqueio de nervos periféricos, especificamente o bloqueio dos nervos femoral e isquiático.

ABSTRACT

Aneurismas de artéria poplítea (AAPs) correspondem a 70,00% dos aneurismas periféricos. A indicação cirúrgica é para aneurismas com diâmetros maiores que 2,0 cm ou sintomáticos. O tratamento é feito por técnicas cirúrgicas convencionais ou endovasculares. Esta última tem ganho muitos adeptos, mas ainda não há consenso estabelecido sobre sua indicação. Objetivo Apresentar a experiência da Divisão de Cirurgia Vascular e Endovascular do Hospital das Clínicas de Ribeirão Preto da Universidade de São Paulo no tratamento dos AAPs. Método Foram revisados casos de reparo convencional e endovascular de AAPs tratados nos últimos cinco anos, avaliando dados demográficos, comorbidades, indicação cirúrgica, complicações pré e pós-operatórias precoces e tardias, tempo de internação e de perviedade em até um ano. Resultados Foram realizadas no período dez cirurgias endovasculares (CE) e 21 cirurgias abertas (CA). O grupo CE teve maior frequência de comorbidades. Houve maior frequência de pacientes sintomáticos no grupo CA (85,00%) do que no grupo CE (40,00%). O Grupo CE apresentou menor número de complicações clínicas e cirúrgicas. A idade entre os grupos e o tempo de internação de cada grupo não apresentaram diferença estatística. A perviedade primária em um ano no Grupo CE foi de 80,00%, enquanto no Grupo CA foi de 75,00%. Conclusão O tratamento endovascular para AAPs apresenta bons resultados, em termos de perviedade com taxas de complicações aceitáveis, em pacientes com risco cirúrgico elevado e anatomia favorável, justificando, assim, a necessidade de mais estudos controlados para modificar a posição da técnica endovascular como uma terapia alternativa para casos selecionados.


Popliteal artery aneurysms (PAAs) account for 70% of peripheral aneurysms. Surgery is indicated for aneurysms that have diameters greater than 2.0 cm or are symptomatic. Repair can be achieved by conventional surgical techniques or using endovascular methods, which are becoming increasingly popular, but for which there is not yet a consensus on indications. Objective To describe the experience of treating PAAs at the vascular and endovascular surgery department of the Hospital das Clínicas de Ribeirão Preto, affiliated to the Universidade de São Paulo (Brazil). Method A review was conducted of cases of conventional and endovascular repair of PAAs over the last 5 years, analyzing demographic data, comorbidities, surgical indications, preoperative and early and late postoperative complications, length of hospital stay and patency, during follow-up of up to 1 year. Results During the period analyzed, ten endovascular surgeries (ES) and 21 open surgeries (OS) were performed. The ES group exhibited a higher frequency of comorbidities. There was a higher frequency of symptomatic patients in the OS group (85%) than in the ES group (40%). The ES group exhibited a lower number of clinical and surgical complications. There were no statistical differences between the groups in terms of age or length of hospital stay. Primary patency at 1 year was 80% in the ES group and 75% in the OS group. Conclusions Endovascular treatment for PAAs offers good results in terms of patency, with acceptable complication rates, in patients with high surgical risk and favorable anatomy. Controlled studies are therefore warranted to validate the endovascular technique and afford it the status of an alternative procedure for use in selected cases.

ABSTRACT

A Síndrome de Ehlers-Danlos (EDS) é uma rara doença hereditária do tecido conjuntivo proveniente de uma alteração da síntese do colágeno. A principal característica da EDS é a extrema fragilidade do tecido conjuntivo, que pode resultar em rotura uterina, perfuração intestinal espontânea e várias doenças vasculares como aneurismas, pseudoaneurismas, dissecções arteriais e roturas espontâneas. Os autores relatam o caso de um paciente de 11 anos de idade que apresentava tumor pulsátil na fossa poplítea esquerda após trauma leve com bola de futebol. Diagnosticado pseudoaneurisma de artéria poplítea pelo doppler arterial, confirmado através da angiografia, optou-se pela exploração arterial e devido à fragilidade da parede não foi possível a sua reconstrução. Realizada a ligadura simples da artéria proximal. Evoluiu com isquemia grave do membro e após autorização da família foi realizada a sua amputação. No segundo dia do pós-operatório o paciente apresentou uma dissecção aguda da aorta torácica, evoluindo a óbito.


Ehlers-Danlos Syndrome (EDS) is a rare inherited connective tissue disease arising from an abnormality of collagen synthesis. The main feature of EDS is the extreme fragility of connective tissues, which can result in uterine rupture, spontaneous intestinal drilling and vascular diseases such as aneurysms, pseudoaneurysms, arterial dissections and spontaneous ruptures. This paper describes the case of an 11-year-old patient who presented a pulsatile mass in the left popliteal fossa after a minor trauma caused by a soccer ball. A pseudoaneurysm of the popliteal artery was diagnosed with arterial Doppler ultrasound and confirmed using angiography. An exploratory investigation revealed that the artery wall was too weak to allow reconstruction and the proximal artery was ligated. The patient developed severe limb ischemia and after authorization by the family the limb was amputated. Two days after surgery, the patient died as a result of acute thoracic aortic dissection.

ABSTRACT

As intervenções endovasculares na artéria femoral superficial para o tratamento da doença arterial oclusiva periférica têm crescido nas últimas décadas. A primeira e a segunda geração de stents na artériafemoral superficial falharam em demonstrar a melhora da perviedade do vaso tratado, devido às altas taxas defratura. O objetivo deste estudo foi avaliar os desfechos clínicos no curto prazo com o uso de stents de nitinolsuperflexíveis de terceira geração no tratamento de lesões ateroscleróticas na artéria femoral superficial. Métodos: Trata-se de um estudo retrospectivo, realizado em único centro, no período de junho de 2013 a maio de 2014. Um total de 27 pacientes foi submetido à angioplastia com stents de nitinol superflexíveis de terceira geração em lesões ateroscleróticas da arterial femoral superficial. Resultados: A média de idades foi de 68 ± 12 anos, 55,6% eram do sexo feminino e 74,1%, diabéticos. Os pacientes foram classificados em TASC B e C em 77,7% dos casos. O sucesso técnico foi de 100%. Houve aumento do índice tornozelo-braquial de 0,35 ± 0,1 pré-intervenção para 0,75 ± 0,2 na alta hospitalar. O seguimento médio dos pacientes foi de 6,7 ± 2,3 meses. A taxa de patência primária foi de 96,3%. A taxa de salvamento de membro foi de 100%. Não ocorreram fraturas de stent documentadas por raios X. Conclusões: A angioplastia com uso de stent de nitinol superflexível de terceira geração demonstrou ser efetiva no tratamento das lesões ateroscleróricas da artéria femoral superficial...


Endovascular interventions in the superficial femoral artery for the treatment of peripheral arterial occlusive disease have increased over the last decades. The first- and second-generation stents in the superficial femoral artery have failed to demonstrate improved patency of the treated vessel due to high fracture rates. The aim of this study was to evaluate the clinical, short-term outcomes of using third-generation superflexible nitinol stents in the treatment of atherosclerotic lesions in the superficial femoral artery. Methods: This was a retrospective study carried out in a single center, from June 2013 to May 2014. A total of 27 patients underwent angioplasty with third-generation superflexible nitinol stents in atherosclerotic lesions of the superficial femoral artery. Results: The mean age was 68 ± 12 years, 55.6% were females, and 74.1% were diabetics. Patients were classified as TASC B and C in 77.7% of cases. Technical success was 100%. There was an increase in the anklebrachial index from 0.35 ± 0.1 before the intervention to 0.75 ± 0.2 at hospital discharge. The mean followupof patients was 6.7 ± 2.3 months. The primary patency rate was 96.3%. The limb salvage rate was 100%. There were no stent fractures documented by X-rays. Conclusions: Angioplasty with third-generation superflexible nitinol stent placement was shown to beeffective in the treatment of atherosclerotic lesions of the superficial femoral artery...

ABSTRACT

An 83-year-old female patient with a history of prior endovascular treatment to repair an abdominal aortic aneurysm presented with intense pain and edema in the left leg, with hyperemia and localized temperature increase. Doppler ultrasonography revealed a voluminous aneurysm of the popliteal artery with a contained rupture, and hematoma involving the popliteal fossa and the medial and anterior surfaces of the knee causing compression of the popliteal vein. Endovascular repair was accomplished with covered stents and the rupture was confirmed. during the procedure The aneurysm was excluded and the signs and symptoms it had caused resolved completely, but during the postoperative period the patient developed sepsis of pulmonary origin and died.


Mulher de 83 anos, com tratamento endovascular prévio de aneurisma de aorta abdominal, iniciou com quadro de dor intensa e edema de perna esquerda, evoluindo com hiperemia e calor local. Ao exame eco-Doppler, apresentou aneurisma volumoso de artéria poplítea roto contido, com hematoma abrangendo fossa poplítea, nas faces medial e anterior de joelho, causando compressão da veia poplítea. Durante a correção endovascular com stent recoberto, foi confirmada a presença de rotura do aneurisma. O aneurisma foi excluído e a paciente teve regressão completa dos sinais e sintomas decorrentes dele; porém, evoluiu no pós-operatório com sepse de origem pulmonar e óbito.

ABSTRACT

The authors describe treatment of a patient who presented an arteriovenous fistula between the popliteal vessels more than 20 years after a gunshot wound. The patient underwent endovascular treatment using Viabahn (Gore®) stent grafts, but, because of the large disparity in popliteal artery diameters proximal and distal of the fistula, the endovascular treatment was unsuccessful. The superficial femoral artery was then banded around the stent graft that was deployed previously. This improvised strategy allowed an open surgical approach to be performed far from the fistula site, reducing the risks of operating in a region with anatomic distortions and significant enlargement of the surrounding venous structures, which would certainly have increased the likelihood of iatrogenic injuries.


Os autores descrevem o tratamento de um paciente portador de fístula arteriovenosa entre vasos poplíteos com mais de 20 anos de evolução, após ferimento por projétil de arma de fogo. O paciente foi submetido a tratamento endovascular pelo implante de stents revestidos Viabahn (Gore®), porém o mesmo não foi bem sucedido devido à diferença de diâmetro entre a artéria poplítea proximal e a distal à fístula. A artéria femoral superficial foi submetida à cerclagem com fios de sutura ao redor do stentgraft previamente implantado. Esse recurso de improvisação permitiu uma abordagem distante do sítio da fístula, diminuindo os riscos do acesso cirúrgico em uma região com distorções anatômicas e vasos sanguíneos ectasiados, o que certamente acarretaria maior risco de lesões iatrogênicas.

ABSTRACT

Pseudoaneurysms or false aneurysms of the popliteal artery are uncommon arterial disorders. These disorders most commonly result from trauma and iatrogenic lesions following orthopedic procedures. The authors report a rare case of popliteal artery pseudoaneurysm in which etiology was unknown. The authors also demonstrate that Doppler ultrasonography may be sufficient for planning vascular surgical procedures and that the open surgical approach is the treatment of choice for cases in which the symptomatic lesion causes local compression...

ABSTRACT

A claudicação intermitente está frequentemente associada à doença aterosclerótica, mas diagnósticos diferenciais devem ser pesquisados em pacientes sem fatores de risco tradicionais. A doença cística adventicial, de etiologia incerta, acomete em maior proporção a artéria poplítea e, eventualmente, apresenta-se como claudicação intermitente. Apresentamos um caso da doença e seu manejo cirúrgico, e discutimos a etiopatogenia, os aspectos diagnósticos e terapêuticos da enfermidade.


Intermittent claudication is frequently associated with atherosclerotic disease, but differential diagnosis must be sought in patients with no traditional risk factors. Cystic adventitial disease, of unknown etiology, most frequently affects the popliteal artery, and occasionally presents as intermittent claudication. We report a case of this disease and the surgical treatment, and discuss some aspects related to etiopathogenesis, diagnosis and treatment of this condition.

ABSTRACT

Degeneração cística da artéria poplítea é uma doença vascular rara, de etiologia desconhecida, na qual um cisto com conteúdo mucinoide compromete a artéria e desenvolve estenose ou oclusão do vaso. Apresentamos um caso de um paciente do sexo masculino, 45 anos, admitido na emergência hospitalar, que apresentava quadro de isquemia aguda no membro inferior esquerdo. Submetido à EcoDoppler, angiorressonância magnética e angiografia pré-operatória. Realizada arterectomia com enxerto fêmoro-poplíteo infrainguinal de safena invertida. O exame patológico foi consistente com o diagnóstico de doença cística da artéria poplítea. O paciente encontra-se em acompanhamento ambulatorial e foi acometido pela doença cística no membro contralateral. Os autores descreveram os melhores métodos de diagnóstico e tratamento para a doença, discutindo se o procedimento de urgência foi o mais adequado e se haveria opções terapêuticas alternativas para o caso, além de qual seria a melhor conduta a ser realizada no membro contralateral também acometido pela doença.


Cystic adventitial disease of the popliteal artery is a rare vascular disease of unknown etiology in which a mucin-containing cyst may compromise the artery and, because of the compression, develops stenosis or occlusion of affected artery. We report the case of a 45-year-old male with cystic adventitial disease of the left popliteal artery, after admission for an acute limb ischemia in his left leg, diagnosed non-invasively with EcoDoppler vascular dual scan, magnetic resonance angiography, angiography. Performed complete removal of the cyst with arteriectomy and venous replacement. The pathologic result ware consistent with the diagnostic of cystic adventitial disease. The patient is in ambulatory follow up and was affected by cystic disease in the contralateral limb. The authors described the best methods of diagnosis and treatment for cystic adventitial disease, discussing if the urgency procedure was the most appropriate and whether there was an alternative treatment for the case. Finally, questioning what would be the best procedure to be performed in the other limb.

ABSTRACT

A síndrome do aprisionamento da artéria poplítea caracteriza-se pela compressão desta artéria sendo a principal causa de claudicação intermitente em jovens. Homem, 18 anos, branco, apresentava parestesia, frialdade e palidez do pé direito, iniciada 24 horas após exercício físico. Em membro inferior direito, ausência de pulsos tibial posterior e dorsal do pé. À flexão dorsal e flexão plantar forçadas, houve diminuição dos pulsos tibial posterior e dorsal do pé à esquerda. Tratado cirurgicamente, o paciente apresentou pulso em ambas as artérias. A síndrome é mais frequente em homens e a prevalência varia entre 0,16 e 3,5 por cento. O aprisionamento da artéria poplítea tipo III é mais comum. A falta de tratamento pode levar à embolia, trombose e aneurismas pós-estenóticos. Esta síndrome deve ser lembrada como causa de dor na perna, especialmente em homens jovens e de prática esportiva intensa.


Popliteal artery entrapment syndrome is the compression of the popliteal artery and is the main cause of intermittent claudication in young patients. An 18-year-old man was admitted at our service complaining of right foot paresthesia, coldness, and pallor that appeared 24 hours after physical activity. Posterior tibial and dorsal artery of foot pulses were not present in right lower limb. Diminished posterior tibial and dorsal artery of the foot pulses were found in left lower limb at dorsal flexion and forced plantar flexion. After surgery, both pulses were present. This syndrome is more frequent in men and its prevalence varies between 0.16 and 3.5 percent. Popliteal artery entrapment type III is most common. Non-treated entrapment can lead to embolism, thrombosis and post-stenotic aneurysms. The syndrome must be considered as a cause of lower limb pain specially in young men with intense sport practice history.

ABSTRACT

Contexto: A terapia endovascular tem avançado muito como tratamento para a doença arterial oclusiva infrainguinal, principalmente com o desenvolvimento dos materiais e dos stents autoexpansíveis de nitinol. Objetivo: Avaliar os resultados e os fatores determinantes da angioplastia fêmoro-poplítea em pacientes portadores de isquemia de membros inferiores. Métodos: Foram tratados, através de angioplastia com ou sem stent, 114 pacientes, e acompanhados por um período médio de 12 meses. A média de idade foi de 66 anos; 53 por cento eram do sexo feminino; 23,7 por cento eram portadores de claudicação incapacitante; 8,8 por cento, de dor isquêmica de repouso; e 67,5 por cento, de lesão trófica. As lesões foram classificadas segundo o TransAtlantic Inter-Society Consensus II em A (53 por cento), B (34 por cento), C (5 por cento) e D (9 por cento). Resultados: A análise angiográfica do leito distal mostrou uma média de 1,4±1,0 artérias infrapoplíteas pérvias. O sucesso inicial foi de 97 por cento. No seguimento de 1, 6, 12 e 24 meses, a perviedade primária foi de 94, 78, 48 e 31 por cento, e a primária assistida, de 94, 84, 73 e 61 por cento, respectivamente (p = 0,005). O leito distal pobre e a presença de diabetes melito foram associados a uma menor perviedade primária (p = 0,01), enquanto a extensão da lesão não influenciou os resultados. As taxas de salvamento de membro em 6, 12 e 24 meses foram de 95, 90 e 90 por cento, respectivamente. Conclusões: A extensão das lesões tratadas não foi um fator determinante em nossa casuística para o menor sucesso da angioplastia, o que pode sugerir que as indicações para o tratamento endovascular possam ser ampliadas para pacientes com lesões TransAtlantic Inter-Society Consensus II C/D.


Background: Endovascular techniques have undergone major advances with regard to the treatment of infrainguinal arterial occlusive disease, mainly as a result of development of new devices and self-expanding nitinol stents. Objective: To evaluate the results and determinant factors of femoropopliteal angioplasty in patients with critical lower limb ischemia. Methods: During the study, 114 patients were submitted to angioplasty or stenting and followed during an average of 12 months. Mean age was 66 years, and 53 percent were female; 23.7 percent presented disabling claudication, 8.8 percent ischemic rest pain and 67.5 percent tissue loss. Lesions were classified as A (53 percent), B (34 percent), C (5 percent) and D (9 percent) according to the TransAtlantic Inter-Society Consensus II. Results: Angiographic run-off analysis showed an average of 1.4±1.0 patent infrapopliteal artery. Initial success rate was 97 percent. At 1, 6, 12 and 24 months of the follow-up period, primary patencies of 94, 78, 48 and 31 percent, and assisted primary patencies of 94, 84, 73 and 61 percent were achieved (p = 0.005). Poor run-off and diabetes mellitus were directly associated with lower primary patency rates (p = 0.01), while angiographic severity of the lesions did not influence results. Limb salvage rates calculated at 6, 12 and 24 months were 95, 90 and 90 percent, respectively. Conclusions: Lesion length was not a determinant factor of lower success rates for angioplasty or stenting, which may suggest that indications for endovascular treatment can be extended to patients with TransAtlantic Inter-Society Consensus II C/D lesions.

ABSTRACT

El aneurisma de arteria poplítea es una entidad patológica que afecta a hombres mayores de 65 años con múltiples morbilidades, siendo la hipertensión arterial la más frecuente. Se asocia a aneurisma contralateral y aneurisma en otras áreas, principalmente la arteria femoral y la aorta abdominal. El diagnóstico en la mayoría de los casos se realiza en pacientes sintomáticos, principalmente debido a complicaciones trombo-embólicas. En este grupo la amputación se realiza hasta en el 20 por ciento de los casos y la mortalidad alcanza el 5 por ciento. La cirugía abierta es el procedimiento de elección, la cual se realiza mayoritariamente por un abordaje medial aislando el aneurisma mediante ligaduras y realizando un bypass con vena autóloga. En el tratamiento de urgencia puede asociarse trombolisis intraoperatoria, la cual mejora el resultado de la cirugía. La cirugía endovascular no ha demostrado ser mejor, sin embargo, posee resultados similares en el tratamiento de pacientes asintomáticos. Existe, actualmente, su indicación en la cirugía de urgencia en aquellos casos en los que la cirugía abierta no se puede efectuar.
