| 目的 观察脑动静脉畸形(AVM)相关癫痫血管构筑特征。方法 回顾性分析70例AVM的常规MRI、全脑时间飞跃MR血管成像(TOF MRA)及数字减影血管造影(DSA)资料,根据有无癫痫发作划分癫痫组(n=22)与非癫痫组(n=48);比较组间临床资料、AVM常规影像学表现及血管构筑特征,以多因素logistic回归分析筛选AVM癫痫发作的独立危险因素。结果 组间病灶位置、是否位于功能区及引流静脉长度差异均有统计学意义(P均＜0.05)。病灶位于功能区[OR(95%CI)=16.409(2.142,125.733),P=0.007]及引流静脉较长[OR(95%CI)=1.350(1.143,1.594),P＜0.001]均为AVM癫痫发作的独立危险因素。结论 病灶位于功能区及引流静脉较长均为AVM癫痫发作的独立危险因素。引流静脉长度可作为识别癫痫高风险AVM的简单、可重复的量化指标。 |

| Objective To explore the angioarchitectural characteristics of brain arteriovenous malformations (AVM) associated with epilepsy. Methods Data of conventional MRI, whole brain time of flight MR angiography (TOF MRA) and digital subtraction angiography (DSA) of 70 cases of AVM were retrospectively analyzed. The patients were divided into epilepsy group (n=22) and non-epilepsy group (n=48) based on presence or absence of epileptic seizures, and clinical data, conventional imaging findings and angioarchitectural characteristics of AVM were compared between groups. Multivariate logistic regression analysis was employed to identify independent risk factors of seizures associated with AVM. Results Significant differences of lesion’s location, located in functional area or not, as well as of the length of draining vein were found between groups (all P＜0.05). Lesion located in functional area (OR[95%CI]=16.409[2.142, 125.733], P=0.007) and longer draining vein length (OR[95%CI]=1.350[1.143, 1.594], P＜0.001) were both independent risk factors of AVM related seizures. Conclusion Lesion located in functional area and longer draining vein length were both independent risk factors of AVM related seizures. The length of drainage vein was a simple and repeatable quantitative indicator for identifying AVM at high risk of epilepsy. |
