Abstract: PURPOSE: To investigate the effect of combination of radiofrequency ablation with DSA-guided sclerotherapy of polidocanol foam in patients with oral and maxillofacial venous malformations. METHODS: The clinical data of 38 patients with venous malformation in Xuzhou Central Hospital from 2019 to 2020 were retrospectively analysed. All patients underwent combined therapy of radiofrequency ablation with DSA-guided sclerotherapy of polidocanol foam. The curative effect was observed in follow-up of minimum 6 months. RESULTS: The patients were divided into 2 groups according to Puig's classification, type Ⅰ(n=20) and type Ⅱ(n=18). All patients underwent radiofrequency ablation as well as DSA-guided sclerotherapy of polidocanol foam for 2-4 sessions. Polidocanol foam was made by means of Tessari's method with the ratio of 1:3(1% polidocanol vs air). Eight cases were cured, 29 cases were basically cured and 1 was less effective. The cure rate was 21.05%(8/38), and the total effective rate was 97.37%(37/38). All 38 cases had mild swelling after sclerotherapy, and the swelling gradually subsided after 3 days. Two cases had skin tension blisters, and 1 case had mild skin ulceration cured after symptomatic treatment. No serious complications such as allergic reaction, ectopia embolism, local or systemic infection occurred. Postoperative follow-up was conducted for 6-12 months. No recurrence, choke, skin rupture, fistula and other serious complications were found. CONCLUSIOINS: According to Puig's classification, it is safe and effective to select combination of radiofrequency ablation with DSA-guided sclerotherapy of polidocanol foam in patients with oral and maxillofacial venous malformations.
