The presence of severe tortuosity of the vertebral arteries (VAs), both at their origin from the subclavian artery and at the level of the third segment, impeded navigation of the catheter for embolization of the aneurysm with Guglielmi detachable coils (GDCs).<\/jats:p>\n<jats:p content-type=\"fine-print\">A direct surgical approach was considered to be a high-risk procedure because of the bilateral occlusion of the ICAs and the size of the aneurysm. The following therapeutic strategy was therefore adopted: 1) balloon occlusion test of the left VA; 2) vertebro\u2014vertebral bypass with saphenous vein graft to provide a pathway for subsequent embolization; 3) ICA\u2014left middle cerebral artery bypass to ensure blood flow in the event that embolization resulted in closure of the PCoA; and 4) GDC embolization of the aneurysm via the posterior circulation graft to ensure complete exclusion of the lesion from the arterial circulation and preservation of the PCoA. At 3-month follow-up review the patient did not present with any neurological deficits; at 1-year control examination, magnetic resonance (MR) imaging and MR angiography both confirmed complete exclusion of the aneurysm and patency of the two bypasses.<\/jats:p>","DOI":"10.3171\/jns.2002.96.1.0135","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:51:36Z","timestamp":1242237096000},"page":"135-139","source":"Crossref","is-referenced-by-count":20,"title":["Bypass combined with embolization via a venous graft in a patient with a giant aneurysm in the posterior communicating artery and bilateral idiopathic occlusion of the internal carotid artery in the neck"],"prefix":"10.3171","volume":"96","author":[{"given":"Antonio","family":"Santoro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emiliano","family":"Passacantilli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giulio","family":"Guidetti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mauro","family":"Dazzi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guido","family":"Guglielmi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giampaolo","family":"Cantore","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"392","DOI":"10.1016\/0090-3019(95)00033-X","article-title":"Microsurgical anatomy of the atlantal part of the vertebral artery.","volume":"44","author":"Abd el-Bary","year":"1995"},{"key":"b2","series-title":"Acta Neurol Scand","doi-asserted-by":"publisher","first-page":"207","DOI":"10.1111\/j.1600-0404.1991.tb04939.x","article-title":"True posterior communicating artery aneurysm.","volume":"84","author":"Akimura","year":"1991"},{"key":"b3","series-title":"No To Shinkei","first-page":"517","article-title":"[A case of bilateral absence of internal carotid with cerebral aneurysm.]","volume":"39","author":"Anegawa","year":"1987"},{"key":"b4","series-title":"Neurol Med Chir","doi-asserted-by":"publisher","first-page":"860","DOI":"10.2176\/nmc.36.860","article-title":"Intracranial aneurysms associated with moyamoya disease.","volume":"36","author":"Borota","year":"1996"},{"key":"b5","series-title":"J Neurosurg Sci","first-page":"71","article-title":"Treatment of aneurysms unsuitable for clipping or endovascular therapy.","volume":"42","author":"Cantore","year":"1998"},{"key":"b6","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"216","DOI":"10.1097\/00006123-199901000-00132","article-title":"Spontaneous occlusion of a supraclinoid aneurysm after the creation of extra-intracranial bypasses using long grafts: report of two cases.","volume":"44","author":"Cantore","year":"1999"},{"key":"b7","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"955","DOI":"10.1097\/00006123-199605000-00021","article-title":"Aneurysm clipping after endovascular treatment with coils: a report of eight patients.","volume":"38","author":"Civit","year":"1996"},{"key":"b8","series-title":"Clin Neurol Neurosurg","doi-asserted-by":"publisher","first-page":"S238","DOI":"10.1016\/S0303-8467(97)00082-6","article-title":"Guidelines for the diagnosis and treatment of spontaneous occlusion of the circle of Willis (moyamoya disease).
