Abstract: Objective To observe the therapeutic effect of endovascular embolization for perimedullary arteriovenous fistula(PMAVF).Methods Data of 8 PMAVF patients who underwent endovascular embolization were retrospectively analyzed.Findings of digital subtraction angiography(DSA)immediately and 6 months after treatment were reviewed,and the modified Aminoff-Logue score(mALS)was compared before and 6 months after treatment.Results Among 8 cases of PMAVF,there were 2 cases of type Ⅰ,5 cases of type Ⅱand 1 case of type Ⅲ,among them 3 were treated with Onyx glue while 5 with Glubrane glue.The immediate DSA results after treatment showed complete embolization of the fistula in all 8 cases,while those 6 months after treatment showed no recurrence.One case recovered and the other 7 cases improved,and mALS(2.25±2.12)6 months after treatment was lower than that(5.50±2.39)before treatment(P＜0.05).Conclusion Endovascular embolization could safely and effectively treat PMAVF.
