Results of surgical management of internal carotid artery aneurysm by the cervical approach.
From 1981 to 1995 a total of 14 patients with a mean age of 52 years (range: 23-71) underwent surgery for 15 aneurysms of the extracranial internal carotid artery. Fusiform aneurysms of the carotid bifurcation were not included in this study. Aneurysm led to brain ischemia in 10 cases and rupture in one case. In the remaining four cases, aneurysm was asymptomatic including three that were detected following hemispheric stroke related to a contralateral aneurysm. The etiology was spontaneous dissection in four cases, blunt trauma in three cases, fibromuscular disease in five cases, and atheroma in three cases. The upper limit of the aneurysm was located at C1-C2 in six cases, at C1 in three cases, and above C1 (at the base of the skull) in six cases. The cervical approach was used to successfully perform 12 revascularizations and three ligations (including one after extra-intracranial bypass). There were no postoperative deaths. One transient ischemic attack (TIA) occurred after ligation. Peripheral facial paralysis (PFP) occurred in four of the nine cases in which an extended cervical approach was used. No patients were lost to follow-up. Mean duration of follow-up was 4 years (range: 2 months-10 years). Two patients died at 2 and 4 years of causes unrelated to the procedure. All carotid reconstructions are currently patent and no neurologic manifestations have occurred. PFP persisted in one case. The results of this series confirm that surgical therapy of aneurysms of the extracranial internal carotid artery achieves satisfactory short- and medium-term results and that the extended cervical approach allows treatment of lesions near the base of the skull.
