摘要

由于30%的缺血性脑卒中病例可以通过早期干预和脑组织再灌注来控制,因此脑血管供应一直引起研究人员的兴趣。脑底侧动脉圈或威利斯圈的变化并不罕见,可追溯到胚胎学原因。该研究的目的是更新变化,并提出临床适用的简单分类威利斯环的完整性。本研究是在65个用福尔马林固定的成年男女的大脑上进行的。仔细观察圆的每个组成部分,并测量外径。据此,根据血管的直径将其分为经典、狭窄和发育不良三类。没有考虑到任何部分。因此,这些圈子按假定的职能范围分为I、II、III和IV类。30.8%的圆是完整的。在前节段,最常见的变异是脑动脉融合和交通动脉再生。后段以狭窄的大脑动脉和胎儿型交通动脉最为常见。发育不全和发育不全多见于右圆后段。左右侧变异均值的P值有统计学意义(P

Morphological evaluation of completeness of Circle of Willis.

The cerebral vascular supply has always stirred interest among researchers since ischemic stroke in 30% cases can be managed by early intervention and reperfusion of brain tissue. Variations of collateral arterial circle at the base of brainor Circle of Willis are not uncommon which can be dated back to embryological causes. The aim of the study is to update the variations and to propose a clinically applicable simple classification for completeness of Circle of Willis. The present study was done on 65 formalin fixed adult human brains of both genders. Each component of the circle was observed carefully and the external diameters were measured. Accordingly, the vessels were defined into different categories as classical, narrow and hypoplastic as per their diameter. Absence of any segment was taken into account. Consequently, the circles were classified into Type I, II, III and IV as per presumed functional competence. 30.8% of the circles were found to be complete. In anterior segment fused cerebral artery and aplastic communicating artery were the commonest variations. In the posterior segment, narrow cerebral artery and fetal type of communicating artery were encountered most frequently. Hypoplasia and aplasia were more on the right posterior segment of the circle. P value for means of right and left side variations was statistically significant (p < 0.0001). Fetal PCoA was the most common variation noted. Incidence of hypoplasia was more common in cerebral arteries as opposed to aplasia, which was more common in communicating arteries. Type II was the most common variant. Left posterior quadrant had the highest incidence of incompleteness.

期刊介绍: The official English journal of the Japanese Association of Anatomists, Anatomical Science International (formerly titled Kaibogaku Zasshi) publishes original research articles dealing with morphological sciences. Coverage in the journal includes molecular, cellular, histological and gross anatomical studies on humans and on normal and experimental animals, as well as functional morphological, biochemical, physiological and behavioral studies if they include morphological analysis.
