  • Title: Vertebral artery reconstruction: results in 106 patients.
    Author: Habozit B.
    Journal: Ann Vasc Surg; 1991 Jan; 5(1):61-5. PubMed ID: 1997078.
    Abstract:
    Between January 1982 and December 1989, we performed 109 revascularizations of the vertebral artery in 106 patients. Eighty-six patients (81%) had isolated vertebrobasilar insufficiency, 18 (17%) had associated carotid and vertebrobasilar pathology while two (2%) had isolated carotid symptoms. The procedures performed included 98 revascularizations of the proximal vertebral artery and 11 reconstructions of the distal vertebral artery. One distal revascularization was required after early failure of proximal revascularization. In 36 cases (34%), a concomitant ipsilateral carotid artery revascularization procedure was performed, and in one case, an ipsilateral subclavian artery aneurysm was excised. Two patients (1.9%) died postoperatively and five patients (4.7%) had nonfatal neurologic complications. Four of these seven complications occurred after combined vertebral and carotid surgery. One hundred early follow-up arteriograms were obtained (92% of reconstructions). There were four occlusions, two of which were associated with neurologic deficits. Three patients were lost to follow-up. Mean follow-up was 48 months (4-100 months). Seven patients died in the late follow-up period (after one month). Actuarial five year survival was 91%. Overall patency at five years was 96%. The study of late neurologic events showed that 63% of patients had complete recovery, 30% improvement, and 7%, failure or aggravation of symptoms.
