Carotid artery grafting for restenosis after carotid endarterectomy.

The paper analyzes outcomes of 12 internal carotid artery (ICA) graftings for repeat stenosis after carotid endarterectomy (CEA) in 11 patients. In 6 cases restenosis occurred after eversion CEA, in 5 - after conventional patch CEA, and in 1 case - after ICA patch angioplasty for post-CEA restenosis. Critical restenosis >75% in reconstruction area was an indication for surgical intervention. There was 1 case of graft thrombosis in early postoperative period with hemispherical stroke and lethal outcome. Eight patients were examined in late postoperative period. Mean follow-up was 34?+/-?8.44 months (from 16 to 48 months). No cerebrovascular disturbances in operated ICA feeding area were detected. In 6 patients graft patency was good, while 2 smoking patients with diabetes mellitus and hyperlipidemia demonstrated repeat restenosis of proximal anastomosis >70%.
