TEIXEIRA, Gabriela et al. Superficial Femoral Artery Aneurysmal Degeneration - Sixteen years after superficial femoral artery endarterectomy and vein patch angioplasty. []. , 15, 3, pp.215-218. ISSN 1646-706X.

^len^aSuperficial femoral artery (SFA) aneurysms are rare clinical disorders, with few case reports and small series published concerning atherosclerotic aneurysms. We report a clinical case a giant aneurysm of the SFA, in a patient previously submitted to extensive SFA endarterectomy and vein angioplasty. A 73-year-old man presented at a routine vascular surgery consultation. The patient had been submitted to a right SFA endartectomy and vein patch angioplasty, sixteen years ago, for intermittent claudication. Physical examination demonstrated a large pulsatile mass of the right thigh. His right pedal pulse was palpable. Ultrasound and computed tomography scan confirmed a 78x71x240mm aneurysm of the right superficial femoral artery. He was proposed to aneurysmectomy and femoro-popliteal bypass. During operative intervention, proximal and distal control was obtained and the aneurysm opened. A large amount of thrombus was removed and a femoro-popliteal bypass was performed using the ipsilateral great saphenous vein. The postoperative period was uneventful, as was the patient recovery. In our report, the aneurysmal area matched precisely to the endarterectomised area and no other aneurysms were found. So we are facing an uncommon case of a SFA degeneration into a giant aneurysm after extensive endarterectomy and vein angioplasty.^lpt^aOs aneurismas da artéria femoral superficial (AFS) são entidades clínicas raras, com poucos casos clínicos e pequenas séries publicadas, normalmente relativas a aneurismas de etiologia aterosclerótica. Nós reportamos o caso clínico de degenerescência aneurismática da artéria femoral superficial, num doente previamente submetido a endarterectomia da AFS e encerramento com patch de veia grande safena. Um homem de 73 anos apresentou-se numa consulta de rotina de cirurgia vascular. O paciente tinha sido submetido a endarterectomia da AFS e angioplastia com patch de veia, dezasseis anos atrás, por claudicação intermitente. Ao exame físico, o doente apresentava uma massa pulsátil na coxa direita. O pulso pedioso era palpável e amplo. O ecodoppler e AngioTC confirmaram o diagnóstico de aneurisma da AFS com 78x71x240mm. O doente foi proposto para aneurismectomia e pontagem femoro-poplítea. Durante o procedimento, foi realizado o controlo proximal e distal da AFS, e o aneurisma foi aberto. Após remoção de quantidade considerável de trombo, foi realizado uma pontagem femoro-poplítea inlay, com recurso à veia grande safena ipsilateral. No caso descrito, a zona aneurismática coincidia precisamente com a extensão de AFS endarterectomizada e nenhum outro aneurisma foi detectado. Este é um caso incomum de degenerescência aneurismática da AFS após endarterectomia e angioplastia com patch de veia.
