Vertebral Artery Hypoplasia | Stroke - AHA/ASA Journals
Apr 3, 2014 · Vertebral artery hypoplasia (VAH) is supposed to be a risk factor for posterior circulation ischemia (PCI), particularly in the territory of the posterior inferior cerebellar artery (PICA). The aim of our study was to determine whether VAH impedes perfusion in the dependent PICA territory even in the absence of manifest PCI.
Vertebral artery hypoplasia as an independent risk factor of ...
Vertebral artery hypoplasia (VAH) is a frequent anatomical variation of vertebral arteries, with emerging evidence suggesting that it contributes to posterior circulation ischemia. However, the relationship between VAH and ischemic stroke remains unknown.

May 19, 2024 · Among the various possible alterations that can affect the VA, vertebral artery hypoplasia (HAV) emerges as a significant variant. This study aims to discern the anatomical features of HAV and its correlation with the clinical conditions of the posterior cerebral circulation.
Vertebral Artery Hypoplasia: Frequency and Effect on ...
The study provides basic information about the relative frequency and potential clinical importance of vertebral artery hypoplasia. It suggests that vertebral artery hypoplasia confers an increased probability of ischemic stroke in the PICA and lateral medullary distributions.
The clinical relevance of vertebral artery hypoplasia - PubMed
Congenital vertebral artery (VA) hypoplasia is an uncommon embryonic variation of posterior circulation. The frequency of this congenital variation was reported to be 2-6% from autopsy and angiograms.
