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

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.
