[Bilateral thrombosis of a femoral pseudoaneurysm].

One case has been described of acute thrombosis of bilateral femoral anastomotic pseudoaneurysm. The clinical finding of bilateral acute ischemia of the lower limbs required urgent surgical treatment. The operative technique consisted of excision of anastomotic aneurysms and replacement by a new segment of prosthesis with an end-to-end anastomosis to the deep femoral artery. Pathogenesis of the pseudoaneurysms at the femoral anastomosis generally recognized numerous factors such as mechanical, graft or suture defects, hypertension, wound complications. Recognition of femoral anastomotic aneurysms is usually simple, when a pulsative mass is noted. In such a case (reported) of thrombosis of bilateral femoral pseudoaneurysms, preoperative diagnosis was more difficult. Anastomotic aneurysms of little size that occur later after original intervention require observation by echography and angiodinography. When rapid enlargement arises, urgent surgical treatment is required, before rupture or thrombosis. The surgical intervention consists of excision of the anastomotic aneurysm and replacement by a new segment of prosthesis between the prosthesis and the common or deep femoral artery. If the reconstruction at the level of femoral artery is not possible, the anastomosis is performed more distally, at the level of popliteal artery. The results are affected by the degree of urgency of surgery, with significant difference in favour of the patients Who underwent elective procedures.
