We hypothesized that multivessel intracranial dolichoectasia may represent a distinct phenotype from single-territory vertebrobasilar dolichoectasia. Elongation is indicated by abnormal laterality or height, ectasia is indicated by abnormal diameter, and doliechoectasia is indicated by the presence of both elongation and ectasia 6. 4 Vertebrobasilar dolichoectasia (VBD) refers to the significant expansion, extension, distortion, or angulation of the vertebral basilar artery caused by various factors. The intracranial vertebral and basilar arteries are preferentially involved. Dolichoectasia of the vertebrobasilar system, a finding of uncertain pathogenesis, is an elon-gation and dilatation of the major arteries of the posterior fossa. 05% to 18% [1,2]. most commonly affected is the vertebrobasilar artery, see: vertebrobasilar dolichoectasia (VDBE) internal carotid artery (ICA) is also at high risk to be affected.

Jun 17, 2016 · The authors review the relevant anatomy and disease origin of VBD; pertinent imaging findings, including intraluminal thrombus and relation to the cranial nerves; and imaging pitfalls, such as the hyperintense vessel sign on MR images and artifacts related to slow flow in the dolichoectatic vessel. There have been relatively few studies following the progression of VBD in patients presenting with a variety of diverse clinical features. 5 mm 1. Vertebrobasilar dolichoectasia (VBD) is diagnosed when the vertebral artery is dilated and tortuous with intraluminal diameter more than 4. Case presentation Here, we report a case study of a male with progressive VBD who was Aug 13, 2024 · Radiographic features. Methods: We present four patients with dolichoectasia that exemplify therapeutic challenges worth discussing in the context of the current literature. Classification Basilar artery diameter Vertebrobasilar dolichoectasia (VBD) is a distinct arteriopathy characterized by an increase in the diameter and length of the basilar artery (BA) and the vertebral artery (VA). Its prevalence in patients with stroke ranges from 7. The purpose of this study was to characterize clinical characteristics and angiographic Apr 20, 2018 · Background Vertebrobasilar dolichoectasia (VBD) is a clinical entity associated with ischemic stroke, compression of cranial nerves or brainstem, and hydrocephalus. Dolichoectasia most frequently involves the vertebrobasilar arteries, and or basilar arteries. [4 39 ] In our case, we report a rare case of dolichoectasia of both anterior and posterior circulation associated with Jan 31, 2023 · Vertebrobasilar dolichoectasia (VBD) is defined as a marked dilation, extension, distortion, or angulation of the vertebrobasilar artery caused by various factors. The objectives of this study are to summarize vestibulocochlear manifestations in subjects with VBD through a case series and to discuss the needs of thorough oto-neurotologic dition, clinical manifestations, the role of radiology in diagnosis and VBD = vertebrobasilar dolichoectasia RadioGraphics 2016; 36:1129–1146 Published online 10. 7, Radiology 207, 103–111 (1998). To be classified as dolichoectasia, in the vertebrobasilar system, the basilar arterial diameter should be >4. 6% to 18. AJNR Am.

Apr 22, 2022 · Therefore, therapeutic interventions aimed at slowing down arterial dilatation and preventing thrombosis could hypothetically play a role in treating patients with dolichoectasia. J. "dolichos") and distension (G. Vertebrobasilar dolichoectasia refers to ectatic and elongated vertebral or basilar arteries, it is usually associated with deterioration of the tunica intima, which causes abnormal vessel distention, atheromatosis and low blood flow velocity that may favor ischemic disease. Until today, the value of computed tomography (CT)/CT angiography (CTA) compared with magnetic resonance imaging (MRI)/time-of-flight MR angiography (TOF-MRA) has not been studied systematically. Nikolaev P, Vertebrobasilar artery dolichoectasia. This condition can affect nearby structures, including the cranial nerves.
