Background: The majority of extratruncular high flow arteries are treated with endovascular therapy, specifically embolization and sclerotherapy. Objective: This study aimed to evaluate the efficacy as well as safety of endovascular management of high-flow arteriovenous malformation (HFAVM). Patients and methods: In a clinical trial we conducted this trial on 12 cases with high-flow AVM at Vascular Surgery and Interventional Radiology Department, Zagazig University and International Medical Center. Endovascular intervention was done to all patients. Results: There was 25% of the cases (3 cases) had complications. One case had a contracture scar, one case had transient ischemia and one case had necrosis, 83.3% of the cases had the complete technique, successful clinical results and very good outcomes while 16.7% were poor. There were no statistically significant differences between cases with poor clinical results and cases with successful clinical results in demographic data, history, clinical data, laboratory findings, or treatment data. Conclusion: Embolosclerotherapy appears to be a safe and effective intervention for high-flow AVMs.
