Is Vertebral Artery Hypoplasia a Predisposing Factor for Posterior Circulation Cerebral Ischemic Events? A Comprehensive Review

Abstract: Vertebral artery hypoplasia is not currently considered an independent risk factor for stroke. Emerging evidence suggest that vertebral artery hypoplasia may contribute to posterior circulation ischemic events, especially when other risk factors coexist. In the present literature review, we present published data to discuss the relationship between a hypoplastic vertebral artery and posterior circulation cerebral ischemia. Despite difficulties and controversies in the accurate definition and prevalence estimat… Show more

“…Hypoplasia and arteriosclerosis stenosis of the vertebral artery are commonly associated with ischemic stroke, especially accompanied with other risk factors (Katsanos, Kosmidou, & Kyritsis, 2013; Park, Kim, & Roh, 2007; Zhang et al., 2017). In our study, 65.2% of patients with acute vertigo or dizziness due to cerebral infarction had vertebral artery abnormalities, which was significantly higher than that found in the noninfarction group.…”

“…Įvairių autorių SA hipoplazijos apibrėžimai skiriasi, t. y. skiriasi spindis, už kurį siauresnė SA vadinama hipoplastiška. Autoriai [2,3,4,5] SA vadina hipoplastiška, jei jos spindis mažesnis negu 2 mm, kiti autoriai [6,7], jei jos spindis mažesnis negu 2,5 mm, o autoriai [8,9], jei jos spindis mažesnis nei 3 mm. Duomenys apie SA hipoplazijos paplitimą populiacijoje svyruoja nuo 2-3 proc.…”

“…iki 30 proc. populiacijos [2]. Iš dalies tokius didelius svyravimus nulemia ir skirtingas SA hipoplazijos apibrėžimas, ir skirtinga tyrimo metodika (ultragarsinis tyrimas, magnetinio rezonanso ar kompiuterinės tomografijos angiografija), skirtingi SA segmentai (V1-V4), kuriame matuojamas kraujagyslės spindis.…”
