Abstract:
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(allP＜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.
