PurposeTo evaluate radiofrequency ablation (RFA) for closure of marginal veins in pediatric and adult patients with venous malformations.Materials and methodsMedical records, imaging and procedure details were retrospectively reviewed in patients who underwent RFA of the marginal vein in a 17-month period. Additional sclerotherapy (n=19) and coil embolization of the marginal vein were performed (n=2).ResultsA total of 23 marginal veins were treated in 20 patients. Mean age at treatment was 16years9.4 (1-37years). Pre-procedural magnetic resonance imaging revealed thoracoabdominal marginal veins in 3 patients. A type I marginal vein (draining in the great saphenous vein below the popliteal vein) was identified in 1 and type IIa/IIb (draining in a median/lateral accessory saphenous vein) in 2/8 cases. Type III (draining into the profunda femoral vein) was detected in 8, and type IV (draining into gluteal veins) in 1. Mean diameter of the marginal veins was 13.2mm4 (7-20mm). Patency was found in 1 during follow-up (22months +/- 9.8). Complete or partial occlusion was achieved in 94.5% of the veins. One patient showed signs of thrombophlebitis after the procedure, and another incomplete paresis of the peroneal nerve.Conclusion RFA is effective as minimally invasive treatment of the marginal venous system. These veins should be treated early in life. Marginal veins with large diameter, residual tributaries and the intrafascial courses usually require adjunct coil embolization and sclerotherapy.Level of Evidence p id=Par5 Case series, Level IV.
