In 48 patients, the symptoms occurred as multiple repeated events, five of which resulted in permanent deficits. The remaining seven patients had single events, four of which caused permanent deficit. These patients had been treated unsuccessfully with antiplatelet agents (37 cases) and with anticoagulant drugs (15 cases) before surgery. Most patients had multiple angiographic abnormalities, including bilateral vertebral stenosis in 19 cases, unilateral vertebral stenosis and contralateral occlusion in 18, unilateral vertebral hypoplasia and contralateral stenosis in 10, subclavian artery stenosis with steal in seven, and bilateral vertebral artery occlusion in one case. Posterior communicating arteries could not be demonstrated angiographically in 18 patients. Thirty-four patients had associated stenotic or occlusive lesions of the internal carotid artery. Forty-eight underwent a vertebral-to-carotid artery transposition. Of these, 18 had an associated carotid endarterectomy and seven had a vertebral artery endarterectomy immediately before the transposition. Two patients had saphenous vein grafts, one from the subclavian and one from the common carotid artery to the vertebral artery. Other surgical procedures included vertebral artery ligation in one case, transposition of the vertebral artery to the thyrocervical trunk in two cases and to the subclavian artery in one case, and endarterectomy of the origin of the vertebral artery in one case. All but two patients had complete resolution of their symptoms: one had persistent dizziness and the other had syncopal episodes. Complications included transient Horner's syndrome (30 cases) which became permanent in four cases, vocal cord paralysis (three cases), elevated hemidiaphragm without respiratory difficulty (two cases), and superficial wound infection (one case). There were no deaths.<\/jats:p>\n<jats:p content-type=\"fine-print\">Although the presentation of patients with vertebrobasilar insufficiency is generally characteristic, we believe that a specific diagnosis can be established only by angiographic means. Anticoagulants have been used to alleviate symptoms in some cases but are ineffective in solving the primary hemodynamic problem. Surgical reconstruction of the affected area deserves further evaluation in the management of these patients.<\/jats:p>","DOI":"10.3171\/jns.1984.61.5.0874","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T16:20:37Z","timestamp":1241799637000},"page":"874-881","source":"Crossref","is-referenced-by-count":51,"title":["Surgical reconstruction of the proximal vertebral artery"],"prefix":"10.3171","volume":"61","author":[{"given":"Fernando G.","family":"Diaz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James I.","family":"Ausman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raul A.","family":"de los Reyes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey","family":"Pearce","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carl","family":"Shrontz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hooshang","family":"Pak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean","family":"Turcotte","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"56","DOI":"10.1227\/00006123-198101000-00011","article-title":"Microsurgical endarterectomy of the intracranial vertebral artery for vertebrobasilar transient ischemic attacks.","volume":"8","author":"Allen","year":"1981"},{"key":"b2","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"307","DOI":"10.1161\/01.STR.12.3.307","article-title":"Long-term outcome in cerebrovascular disease in relation to findings at aortocervical angiography.
