“…Intracranial AV malformations are reported frequently [ 2 – 5 ], but extracranial AV malformations are relatively rare [ 6 ]. They often occur in the maxillofacial neck [ 7 ], torso, and extremities [ 8 , 9 ]. AV malformations appear during embryonic vascular development; most of the cases showed local red skin lesions after birth, with a slightly higher skin temperature, and several cases showed no obvious abnormal changes after birth.…”

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.

Endovascular Management of a Giant High-Flow Lower Limb Arteriovenous Malformation

Abstract: Endovascular therapy could be a safe and effective option for AVM as long as it includes not only feeding vessels embolization but also complete occlusion of the nidus.
