Of 59 cases of vertebrobasilar junction aneurysms diagnosed and treated from January 1977 to April 1986, 21 (35.5%) saccular aneurysms arose in a fenestration of the proximal basilar artery. Defects of the media at the junctures of the fenestrated segments, as well as the possible presence of turbulent flow at the vertebrobasilar junction, may explain the high incidence of vertebrobasilar aneur...

OBJECTIVE To study the efficacy, safety, and feasibility of stent-assistant angioplasty (SAA) in the treatment of symptomatic vertebrobasilar artery stenosis in the elderly. METHODS SAA was performed in 26 elderly patients with symptomatic vertebrobasilar artery stenosis. The success rate, perioperative complications, and long-term effectiveness were evaluated. RESULTS A total of 29 balloon...

N Engl J Med 2005;352:2618-26. Copyright © 2005 Massachusetts Medical Society. ighty percent of strokes are ischemic. twenty percent of ischemic events involve tissue supplied by the posterior (vertebrobasilar) circulation (Fig. 1). The paralysis of vertebrobasilar stroke can be devastating, and some forms have high rates of death. 1 Many cases of vertebrobasilar disease remain undiagnosed or a...

background: vertebrobasilar arterial territory nourishes one-quarter of human brain. it constitutes some vital and strategic parts of the central nervous system. methods: a number of keywords (vertebral, basilar, artery, and territory) were searched in medline (ovid and pubmed) as well as google, proquest, scopus, cochrane library, and science direct online databases. only articles containing a...

Cervical manipulation occasionally causes serious vertebrobasilar complications. The usual cause is vertebral artery dissection, however in some cases there has been no obvious arterial injury. The present paper reviews the mechanisms by which complications occur, particularly when the applied force is trivial or there is no injury to the vertebral arteries, and the factors that increase risk o...

The primitive carotid-vertebrobasilar anastomoses are primitive embryonic cerebral vessels that temporarily provide arterial supply from the internal carotid artery to the longitudinal neural artery, the future vertebrobasilar artery in the hindbrain. Four types known are the trigeminal, otic, hypoglossal, and proatlantal intersegmental arteries. The arteries are accompanied by their correspond...

BACKGROUND The goal of this study was to determine the reliability of TCD in evaluation of vertebrobasilar arteries in comparison with brain MRA in patients suffering from acute vertebrobasilar stroke. METHODS Samples were patients with definite clinical diagnosis of vertebrobasilar stroke. For all patients brain MRI, MRA and TCD were performed during the first 48 hours of admission. Basilar ...

BACKGROUND AND PURPOSE Dissecting vertebrobasilar aneurysms are challenging to treat, and standard treatment modalities remain controversial. We retrospectively evaluated our experience using endovascular techniques to treat these aneurysms. MATERIALS AND METHODS From February 1997 to December 2007, 42 patients with intradural vertebrobasilar dissecting aneurysms underwent endovascular treatm...
