Long-term follow-up of patients with popliteal artery entrapment syndrome treated by endoluminal revascularization


Meier, T O; Schneider, E; Amann-Vesti, B (2010). Long-term follow-up of patients with popliteal artery entrapment syndrome treated by endoluminal revascularization. VASA, 39(2):189-195.

Abstract

The popliteal artery entrapment syndrome (PAES), a rare cause for leg ischemia, is usually treated by surgical removal of the compressing structure and either venous bypass or interposition graft. However, endovascular revascularization followed by surgery to release the artery has been reported as a feasible alternative. So far long-term results of this approach are not known. We report the follow-up of three patients with PAES and thrombotic occlusion of the popliteal and calf arteries treated by local lysis, percutaneous thrombembolectomy and angioplasty followed by musculotendinous dissection. One patient had an uneventful follow-up of 11 years while the second patient developed a popliteal aneurysm four months after the index procedure. In the third patient, angioplasty of a stenosis of the popliteal artery was performed after two years. However, occlusion of the artery occurred two years later due to a small popliteal aneurysm. Endovascular revascularization followed by surgical release of the artery may be a viable alternative in the treatment of PAES especially in cases with distal embolization. However, careful follow-up by duplex ultrasound is mandatory because of the high risk of reocclusion or development of a popliteal aneurysm.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
