Remote endarterectomy for long segment superficial femoral artery occlusive disease. A systematic review

Background: Remote endarterectomy is a minimally invasive procedure which combines open and endovascular surgery for the treatment of tong segment superficial femoral artery (SFA) occlusive disease. We conducted a systematic review of the medical literature to analyze the indications, technical limitations and the outcome of remote SFA endarterectomy (RSFAE). Methods: The English literature was searched using the MEDLINE electronic database up to February 2008. We considered studies comprising at least 10 patients treated with RSFAE and reporting on the primary and/or secondary patency rates. Average primary and secondary patency rates were obtained by weighting the data of each study by the number of limbs treated. Results: Our search identified 19 retrospective or prospective case series; no randomized controlled trials comparing RSFAE with another treatment modality were identified. The average technical success rate was 94% and the procedure-related complication rate was 14.7%. The weighted mean cumulative primary patency rates were 60%, 57% and 35% at 1, 2 and 5 years, respectively. The weighted mean assisted primary patency rates were 75%, 77% and 50% at 1, 2 and 5 years, respectively. The weighted mean secondary patency rates were 88% and 62% at 1 and 2 years, respectively. Conclusions: RSFAE has acceptable short-, medium- and long-term results but patients should undergo intensive surveillance postoperatively. Randomized controlled trials are needed to assess the durability of this procedure as compared to conventional open bypass Surgery. (C) 2008 European Society for Vascular Surgery.
