Abstract | BACKGROUND: The aim of the present study is to evaluate the short-term efficacy and feasibility of radiofrequency ablation in the treatment of complex diffuse arteriovenous (AV) malformations. METHODS: The data of 18 patients (8 male and 10 female) with complex AV malformations treated between December 2014 and June 2019 were analyzed retrospectively. The lesion area was 10 × 7 cm ~ 28 × 30 cm. Under duplex ultrasound guidance, the site with the most abundant blood flow signals in the lesion was percutaneously punctured with the radiofrequency ablation needle ( electrode). The impedance automatic adjustment mode was adopted, and ablation was monitored usingduplex ultrasoundduring the entire process. RESULTS: Of the included patients, 1 had a high fever after two rounds of treatment, 2 had transient hemoglobinuria, and 1 had tissue necrosis in the original ruptured tumor area as well as a penetrating defect in the cheek, which was repaired with a pedicled trapezius myocutaneous flap. In 9 patients who experienced bleeding, the bleeding stopped after one round of treatment. During the follow-up period of 1-5 years, there were 0 grade I (poor) cases, 0 grade II (medium) cases, 7 grade III (good) cases, and 11 grade IV (excellent) cases. CONCLUSION: The "high power and continuous" radiofrequency ablation technique conducted under real-time duplex ultrasoundmonitoring can completely destroy the deep core lesions of AV malformations and effectively control life-threatening massive hemorrhage; it is an effective alternative treatment method for complex diffuse AV malformations in which interventional embolization, sclerotherapy, and surgery are ineffective.
