<jats:sec><jats:title>Purpose</jats:title><jats:p>To describe a novel ultrasound-guided technique for percutaneous radiofrequency ablation of vascular malformations—the “moving shot technique.”</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Preliminary observational cohort study, conducted from June 1, 2019, to January 31, 2021, including all consecutive patients diagnosed with vascular malformations who were treated with ultrasound-guided radiofrequency ablation using the moving shot technique. Only patients who had undergone at least one unsuccessful previous treatment were included (sclerotherapy with ethanol/aethoxysklerol or embolization/surgery).</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Eight patients with a median age of 22 years (interquartile range, 13–31) were included. Patients had different vascular malformations consisting of 1 arteriovenous malformation, 4 venous malformations, and 1 each a mixed venous-lymphatic malformation, a glomuvenous malformation and a FAVA (fibroadipose vascular anomaly). Malformations were located at the limbs in 5 patients (62.5%), the subcutaneous/intramuscular tissue of the body in 2 patients (25%) and at the chin in 1 patient (12.5%). Clinical symptoms were pain in 8 patients (100%), swelling in 6 patients (75%), and partial immobility in 4 patients (50%). All patients showed an improvement of clinical symptoms after treatment with 7 (87.5%) being completely asymptomatic and 1 (12.5%) showing improvement of immobility and pain. No procedural complications, such as nerve damage or skin burns occurred.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>The moving shot technique using ultrasonography-guided radiofrequency ablation is a promising technique for the interventional treatment of vascular malformations and should be validated in multicenter-approaches.</jats:p></jats:sec>
