AbstractThis multicentric Serbian study presents the treatment of 91 extracranial carotid artery aneurysms in 76 patients (13 had bilateral lesions). There were 61 (80.3%) male and 15 (19.7%) female patients, with an average age of 61.4 years. The aneurysms were caused by atherosclerosis in 73 cases (80.2%), trauma in six (6.6%), previous carotid surgery in six (6.6%), tuberculosis in one (1.1%), and fibromuscular dysplasia in five (5.5%). The majority (61 cases or 67%) of the aneurysms involved the internal carotid artery, 29 (31.9%) the common carotid artery bifurcation, and one (1.1%) the external carotid artery. Forty-five (49.4%) aneurysms were fusiform, while 46 (50.6%) were saccular. Twenty-nine (31.9%) cases were totally asymptomatic at the time of diagnosis. The remainder presented with compression in 14 (15.4%) cases, stroke in 11 (12.1%) cases, transient ischemic attack in 33 (36.3%) cases, and rupture in four (4.4%) cases. In cases where the aneurysm involved the internal carotid artery, four surgical procedures were performed: aneurysmectomy with end-to-end anastomosis in 30 (33.0%) cases, aneurysmectomy with vein graft interposition in 20 (22.0%) cases, aneurysmectomy with anastomosis between external and internal carotid artery in eight (8.8%) cases, and aneurysmectomy followed by arterial ligature in three cases. One case of external carotid artery aneurysm also was treated by aneurysmectomy and ligature. Aneurysm replacement with Dacron graft was performed in 29 (31.9%) cases where common carotid artery bifurcation was involved. Two (2.2%) patients died after the operation due to a stroke. They had ruptured internal carotid artery aneurysm treated by aneurysmectomy and ligature. Including these, a total of five (5.5%) postoperative strokes occurred. In two (2.2%) cases, transient cranial nerve injuries were found. Excluding the five patients who were lost to follow-up, 69 other surviving patients were followed from 2 months to 12 years (mean 5 years and 3 months). In this period, there were no new neurological events and all reconstructed arteries were patent. Three patients died more than 5 years after the operation, due to myocardial infarction. Aneurysms of the extracranial carotid arteries are rare vascular lesions that produce a high incidence of unfavorable neurological sequelae. Because of their varied etiology, location, and extension, different vascular procedures have to be used during repair of extracranial carotid artery aneurysms. In all of these procedures, an aneurysmectomy with arterial reconstruction is necessary.
