摘　　要：目的探讨脑动静脉畸形（CAVM）在多层螺旋cT血管造影（MSCTA）中的表现及MSCTA的临床价值。方法收集36例行MSCTA检查的CAVM患者的资料，采用容积再现重组（VR）血管生长技术（AV）进行血管重建，分析供血动脉、引流静脉的表现。结果36例CAVM患者中，病变累及枕叶10例，颞叶9例，额叶2例，顶叶3例，枕叶、小脑半球7例，颞、枕叶3例，额、顶叶2例，均清楚显示畸形血管团、供血动脉及引流静脉；4例合并血管畸形内动脉瘤，2例合并血管畸形外动脉瘤，3例蛛网膜下腔出血，6例脑出血。结论MSCTA能清楚显示CAVM的畸形血管团、供血动脉、引流静脉及合并的动脉瘤。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.
