胚胎型大脑后动脉与基底动脉形态及其缺血事件之间的关系

Relationship between the embryonic posterior cerebral artery, and basilar artery morphology and its ischemic events

摘要

摘要:
目的应用磁共振动脉成像（MRA）技术探讨胚胎型大脑后动脉的存在与基底动脉形态及基底动脉缺血事件发生概率的关系。
方法随机选择行MRA检查的脑血管病病人148例。其中有胚胎型大脑后动脉病人48例，无胚胎型大脑后动脉病人100例。观察胚胎型大脑后动脉的开放情况，测量基底动脉上、中、下三段处的内径，及后循环缺血事件发生情况，进行统计学分析。
结果有胚胎型大脑后动脉组基底动脉上、中、下三段血管内径均小于无胚胎型大脑后动脉组（P < 0.01）。后循环缺血事件患病组基底动脉上、中、下三段血管内径均小于不患病组（P < 0.05）。
结论胚胎型大脑后动脉存在的情况下，基底动脉内径较小且缺血事件发生率增高。

Abstract:
ObjectiveTo investigate the relationship between the embryonic cerebral artery, and morphology of basilar artery and probability of basilar artery ischemic events using magnetic resonance angiography.
MethodsA total of 148 patients with cerebrovascular disease diagnosed by magnetic resonance angiography examination were randomly selected.There were 48 patients with embryonic posterior cerebral artery and 100 patients without embryonic posterior cerebral artery.The openness of the embryonic cerebral artery was observed.The inner diameters of the upper, middle and lower basal artery, and occurrence of posterior circulation ischemic events were measured and analyzed.
ResultsThe diameters of the upper, middle and lower basilar artery in embryonic posterior cerebral artery group were smaller than those in non-embryonic posterior cerebral artery group(P < 0.01).In the posterior circulation ischemic event, the diameters of the upper, middle and lower basilar artery were smaller than those in non-disease group(P < 0.05).
ConclusionsUnder the presence of the embryonic cerebral artery, the inner diameter of basilar artery is smaller, and the incidence rate of ischemic event increases.
