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

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

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

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

Resumo A doença cística da adventícia é uma entidade rara que acomete principalmente a artéria poplítea. A ocorrência em veias é muito rara, e sua etiologia é desconhecida. Clinicamente, apresenta-se como isquemia, trombose ou dor a depender do território acometido. Apresentamos o caso de um paciente masculino jovem referindo nódulo no braço esquerdo. A angiorressonância magnética do membro mostrou lesão cística em contato com a veia basílica, com conteúdo homogêneo e sem realce pós-contraste. Foi realizada ressecção da lesão em bloco com o segmento venoso envolvido. O estudo anatomopatológico foi sugestivo de cisto de adventícia de veia basílica.


Abstract Cystic adventitial disease is a rare entity that most often involves the popliteal artery. It rarely occurs in veins. Its etiology is unknown. Clinically, it presents with ischemia, thrombosis or pain, depending on the vessel affected. Here we present the case of a young male with a nodule in the left arm. Magnetic resonance angiography showed a cystic lesion in contact with the basilic vein, with homogenous content without post-contrast enhancement. The lesion was resected en bloc together with the venous segment involved. The results of microscopic analysis were suggestive of basilic vein cystic adventitial disease.

ABSTRACT

ABSTRACT Objective To analyze the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO2 as primary contrast in patients with no formal contraindication to iodine, aiming to decrease allergic reactions and potential nephrotoxicity in high-risk patients. Methods We describe the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO2 as primary contrast in patients with high risk for open revascularization and no formal contraindication to iodine. We analyzed feasibility of the procedures, complications, quality of the angiographic images, clinical and surgical outcomes, and costs of C and D lesions treated using CO2 as contrast medium. Results The use of CO2 in C and D lesions needed iodine complementation in most of the cases (nine cases) but decreased the potential nephrotoxicity of iodine contrast medium by the reduction of its volume in this group of high-risk patients. The extension of the arterial lesions was the factor that most contributed to the need for iodine supplementation due to the difficulty to visualize the refill after a long arterial occlusion. Conclusion The use of CO2 as contrast in patients with C and D lesions with no restriction for iodine contrast medium was an alternative that did not dismiss the need of iodine supplementation in most of the cases, but could decrease the potential nephrotoxicity of iodine constrast medium.


RESUMO Objetivo Analisar os resultados de dez angioplastias de lesões fêmoro-poplíteas TASC C e D utilizando CO2 como meio de contraste primário em pacientes sem restrição ao meio de contraste iodado com o objetivo de diminuir reações alérgicas e potencial de nefrotoxicidade em pacientes de alto risco. Métodos Descrevemos os resultados de dez angioplastias de lesões fêmoro-poplíteas TASC C e D utilizando CO2 como meio de contraste primário em pacientes de alto risco para revascularização aberta e sem contraindicação formal a iodo. Analisamos possibilidade de execução dos procedimentos, complicações, qualidade das imagens obtidas, desfechos clínicos e cirúrgicos e custos das lesões C e D tratadas com CO2 como meio de contraste. Resultados O uso de CO2 nas lesões C e D necessitou de complementação de iodo na maioria dos casos (nove casos), porém reduziu o potencial de nefrotoxicidade do meio de contraste iodado, diminuindo seu volume nesse grupo de pacientes de alto risco. A extensão das lesões arteriais foi o fator que mais contribuiu para necessidade de suplementação de iodo, devido à dificuldade de visualizar o reenchimento após oclusão arterial longa. Conclusão O uso de CO2 como contraste em pacientes com lesões C e D sem restrição ao meio de contraste iodado foi uma alternativa que não excluiu a necessidade de suplementação com iodo na maioria dos casos, porém pôde diminuir o potencial de nefrotoxicidade do meio de contraste iodado.
