摘要
目的:研究脑动静脉畸形(AVM)的临床特点和影像学特征。方法:回顾性分析104例AVM患者的临床和影像学资料。结果: 104例AVM患者平均年龄为32．13岁。主要表现为颅内出血、头痛、癫痫、肢体瘫痪等。主要累及双侧额叶30例、颞叶28例、顶叶 16例、枕叶14例、颞-顶区9例、基底节12例、小脑9例、胼胝体5例等。典型表现为畸形蜂窝状血管团及增粗的供血动脉和引流静脉。DSA诊断AVM的敏感性为97．5％,其次为MRI,敏感性为74％,头颅CT的敏感性为43％。结论:DSA是诊断AVM的最敏感的方法,对于突发的颅内出血、头痛、抽搐、瘫痪的青少年患者应行头颅DSA和MRI俭查,以便及时发现AVM病灶。
Objective： To study the clinical and imaging feature of cerebral arteriovenous malformations（AVM） . Methods： Retrospective analyses of the materials of clinical and imaging were performed on 104 cases. Results： The average age of patients was 32. 13 years . The main clinical manifestations were intracranial hemorrhage,headache, epilepsy and limb paralysis. There were 30 cases with lesions located in frontal lobe, 28 cases in temporal lobe, 16 cases in parietal lobe, 14 cases in occipital lobe, 9 cases in temporal-occipital zone, 12 cases in basal ganglia, 9 cases in cerebellum and 5 cases in corpus callosum, etc. The typical AVM showed a characteristic honeycomb mass appearance with row feeding arteries and draining veins. The diagnostic sensitivity of DSA was 97. 5%, while the sensitivity of MRI was 74%, and the sensitivity of CT was 43%. Conclusion： DSA examination is the most sensitive in diagnosing of AVM. DSA and MRI examinations are necessary for young patients with intracranial hemorrhage, headache, epilepsy and limb palsy to find AVM in time.
