Endovascular repair of popliteal artery aneurysms: techniques, current evidence and recent experience.
Endovascular repair of popliteal artery aneurysms is a new technique, which has emerged as an alternative to open surgical bypass. However, evidence to support its use is limited. We present a review of current literature relevant to this technique. The MEDLINE search terms were popliteal artery, aneurysm, endovascular, endoluminal and stent. Fifty-eight articles were yielded, of which 21 were studies of endovascular repair by implantation of stent or stent graft of true aneurysms of the popliteal artery. There was only one randomized study. Small numbers of endovascular interventions are reported, with variations in study design and endovascular techniques. Long-term follow-up data is lacking; however, early results have been promising with high rates of initial treatment success. Early thrombosis of stent grafts occurs in approximately 10%, but this does not herald limb loss. Endovascular treatment offers potential benefits over traditional surgery, but needs to be studied further with a large-scale multicentre randomized trial.
