ABSTRACT
Objective To review the three-dimensional characteristics and configuration of cranial base arteries of patients with intracranial berry aneurysms. Methods All the 70 patients with intracranial berry aneurysms (83 cases)were admitted from January to December in 2007. Their images of spiral computer angiography (CT) were presented and analyzed retrospectively. The site, size and figures of aneurysms were recorded, especially the variations of cranial base arteries were analyzed. Results Cerebral anterior communicating artery (ACoA) was the frequent site where aneurysms located. Incidence of ACoA aneurysms was 43.37%(36/83), that of posterior communicating artery (PCoA) was 28.92%(24/83), that of internal carotid artery was 9.64% (8/83), that of middle cerebral artery was 6.02% (5/83), that of A1-A3 was 3.61% (3/83), that of basilar artery was 3.61% (3/83), that of posterior cerebral artery was 2.41% (2/83), that of posterior inferior cerebellar artery was 1.20% (1/83),that of anterior choroidal artery was 1.20% (1/83).The shape of many berry aneurysms was regular. Mutational rate of cranial base arteries among aneurysms were 56.63% (47/83) and ACoA ancurysms with A1 dysplasia rate was 72.22% (26/36). Conclusions The solid shape and vascular variation of intracranial berry aneuryams can be optimally identified by spiral computer angiography. The occurrence of berry aneurysms might be associated with variation of cranial base arteries.
