[Simultaneous carotid and vertebral revascularization in the aged].

Five patients of a mean age of 76, have been submitted to combined vertebral and carotid artery revascularization for a severe vertebro-basilar insufficiency. Vertebral artery revascularization consisted of a transposition to the common carotid artery in one case and of a carotid-distal vertebral artery saphenous bypass graft. The associated carotid artery revascularization consisted of a carotid endarterectomy with patch in 4 cases and without patch in one case. There were no postoperative mortality and no postoperative stroke. Postoperative morbidity included a transitory revascularization syndrome, a myocardial ischemia and a Horner's syndrome. Complete relief of vertebrobasilar symptoms was obtained in 4 patients whereas in one patient only a mild positional vertigo persisted. All vascular reconstructions have been assessed with postoperative arteriography and duplex-scan every six months. At 11 months mean follow-up, all revascularizations are patent. Combined carotid and vertebral artery surgery is effective in well selected cases, and it does not enhance the risk of the two operations performed separately. It also eliminate the possibility of failure of isolated carotid revascularization for vertebrobasilar symptoms.
