Abstract:
Objective:To explore the relationship between the degree of devascularization and clinical outcomes after interventional embolization and sclerotherapy for peripheral arteriovenous malformations.Method:A retrospective analysis was conducted on the data of 37 patients with peripheral arteriovenous malformations admitted at Department of Cardiovascular Surgery, China-Japan Friendship Hospital from July 2021 to June 2023. All patients received the treatment of "nidus" and/or outflow veins embolization combined with sclerotherapy injection. Two experienced physicians evaluated the degree of devascularization before and after treatment, and conducted a correlation study with clinical outcomes after follow-up.Result:All 37 patients were symptomatic. Swelling and pain accounted for 75.7% of all the cases. Twenty-six patients received only one procedure, 3 patients received re-interventional treatments. The average follow-up time was（13.3±5.0）months. Clinical symptoms were completely relieved in 14 patients, and partial relief in 22 patients. The overall effective rate was 97%. There were 6 patients with degree of de vascularization<50% during procedure, 16 patients with degree of 50%-75%, and 5 patients with degree of 75%-90%, 10 cases with degree over 90%. Patients with devascularization degrees less than 60% can not achieve clinical symptom relief.Conclusions:There is a positive correlation between the degree of devascularization and clinical outcomes in the interventional embolization and sclerotherapy of peripheral arteriovenous malformations, and 60% of the degree of devascularization can serve as the "threshold" for effectiveness of treatment.
