Abstract
Objective To evaluate the manifestation of cerebral arteriovenous malformations (CAVM) on multi-slice spiral CT (MSCT) angiography and the clinical value of this examinaion.Methods The data on 36 patients with CAVM undergoing MSCT angiography were collected.Vascular reconstruction were performed by volume rendering and AV.The manifestations of feeding arteries and draining veins were then analyzed.Results Among these 36 patients with cerebral arteriovenous malformations,ten patients had the lesion in occipital lobe,nine in temporal lobe,two in frontal lobe,three in parietal lobe,seven in occipital lobe and cerebellar hemisphere,three in occipital and temporal lobe,and two in frontal and parietal lobe,with a clear display of masses of deformed vessels,feeding arteries and draining veins; 4 patients were complicated by intra-aneurysm of CAVM,2 were complicated by extra-aneurysm of CAVM,3 concurred with subarachnoid hemorrhage,and 6 concurred with cerebral hemorrhage.Conclusions Multi-slice spiral angiography can clearly detect masses of deformed vessels,feeding arteries,draining veins,and coexisting aneurysms. Key words: Cerebral arteriovenous malformations; CT angiography
