BACKGROUND Embolization via a persistent trigeminal artery, one of the embryonic vascular connections that may persist between the carotid and basilar arteries, is an unusual occurrence. CASE DESCRIPTION We describe a 76-year-old man with bilateral occipital infarctions presumably related to an ulcerated left carotid stenosis. Clinically, a left inferior homonymous quadrantanopia was present....

Using technetium-99m-labeled hexamethylpropyleneamineoxime [( 99mTc]HM-PAO) and single-photon emission computed tomography, we measured changes in regional cerebral blood flow in a 58-year-old man during an attack of vertebrobasilar insufficiency. Angiography demonstrated compression of the left vertebral artery by the osteophytes of cervical spondylosis when the patient turned his head to the ...

BACKGROUND AND PURPOSE Fusiform vertebrobasilar giant aneurysms are a rare (<1% of all intracranial aneurysms) but challenging aneurysm subtype. Little data are available on the natural history of this aneurysm subtype and the impact of the use of flow-diverting stents on the long-term clinical and imaging follow-up. In this article, we present our experience with the treatment of fusiform vert...

VERTEBROBASILAR ischemia is a common disorder which is now frequently diagnosed by medical students, house officers, practitioners, and consultants alike. Although brainstem softening was recognized in the 19th century, the underlying pathology was not understood until the classic report of Kubik and Adams in 1946.' These authors called attention to the clinical features in patients discovered ...

BACKGROUND Tortuous blood vessels are commonly seen in the cerebral arteries. The association between vertebrobasilar artery tortuosity and vascular vertigo remains obscure. CASE PRESENTATION We describe two patients with vascular vertigo who had bilateral curving and spiral looping in multiple segments of the vertebral arteries and also exhibited basilar artery tortuosity. Both patients had ...

Treatment options of ruptured vertebrobasilar fusiform aneurysms (VFA) are limited and often carry significant mortality and morbidity. We report the use of Pipeline Embolization Device (PED) to successfully treat a patient with a ruptured vertebrobasilar fusiform aneurysm (VFA) who presented with subarachnoid hemorrhage (SAH). A 73 year-old man with a history of cardiac stent placement seven d...

BACKGROUND Vertebrobasilar dolichoectasia (VBD) is a rare vasculopathy. The etiology of this disease is unknown. Transient ischemic attacks (TIAs) of vertebrobasilar system refer to a transient (< 24 hours) lowering of blood flow in the posterior circulation of the brain. We present a case of dolichoectasia in the vertebrobasilar artery that presented with TIAs. CASE REPORT A hypertensive 54-...

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...
