Carotid endarterectomy (CEA) is the gold standard for treatment of carotid artery stenosis. CEA can be challenging, even technically impossible. Prosthetic carotid bypass grafting is a proven and safe alternative when CEA is hazardous. An alternative technique that is prosthetic carotid bifurcation resection and interposition of a polytetrafluorethylene graft (BRIG) is described in this article. In our Department of Vascular Surgery, between January 2007 and October 2014, 103 BRIG procedures were performed. The outcome of conventional CEA and patients treated by the BRIG procedure were compared. Within the same period of time 50 CEA procedures (32.7%) were performed. Morbidity, mortality, and postoperative restenosis were compared. The 30-day mortality was 1% for the BRIG group and 0% in the CEA group (P value, 0.4839). The 30-day stroke rate was 1.9% for the BRIG group and 0% in the CEA group (P value, 0.3222). One patient died in the early postoperative period from acute myocardial infarction. A total of 13 (8.5%) patients died during follow-up, none of which were surgery related. Median follow-up was 29.1 months. There was a statistically higher restenosis rate in the CEA group compared with the BRIG group (16.0% vs. 1.9%, P value, 0.0053). Other complications were comparable. Mean operating and clamping time were significantly shorter in the BRIG group. BRIG appears to be a safe and feasible surgical alternative to CEA. The technique allows for shorter operating time, shorter clamping time, and appears to result in lower restenosis rates. Complication rates seem to be comparable to CEA. Prospective, randomized controlled trials on this topic are needed. To perform bilateral procedures, a bifurcation graft should be created to revascularize both the internal and external carotid artery.
