Abstract: PURPOSE: To investigate the efficacy and safety of interventional embolization in the treatment of frontal arteriovenous malformation (AVM). METHODS: A retrospective study was used to analyze 9 patients with frontal AVM who were treated in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. The patients were treated with interventional embolization under the guidance of DSA. The scope of lesions was observed through DSA, and the injection dose of sclerosing agent was predicted so that the drug could be injected into the lesion cavity. The efficacy, adverse reactions and complications of all patients were observed and analyzed. RESULTS: Among the 9 patients, there were 7 males(77.8%) and 2 females(22.2%), aged from 1.5-20 years old. Local swelling or mass was the main reported symptom(66.7%). The blood supply arteries of the cases involved in this study included superficial temporal artery and ophthalmic artery. All patients received interventional embolization treatment under general anesthesia, a total of 19 times (each patient received 1-6 times, average 2.1 times/person), and the average single dose of absolute ethanol was 9.0 mL. A total of 80 coils (4.2 coils/time on average) were used for 5 times (80 coils/19 times) with absolute ethanol embolization. In addition, bleomycin was used 3 times, pingyangmycin was used 2 times, and 3% polydocanol was used 1 time to assist embolization. Among the 9 cases included in this study, 4 cases were cured, 3 cases were basically cured, 2 cases were improved, and the effective rate of treatment was 100%. No local or systemic complications were reported in all patients. CONCLUSIONS: In the treatment of frontal arteriovenous malformation, correct diagnosis according to clinical and imaging manifestations, and interventional embolization with anhydrous ethanol according to DSA angiography results can reduce trauma, improve symptoms, control lesions, and obtain relatively satisfactory treatment results. This scheme is safe and effective.
