Balloon occlusion as an adjunctive technique during sclerotherapy of Puig's classified advanced venous malformations

Objective Puig types 2 through 4 venous malformations (VMs) are challenging to treat with sclerotherapy given their robust systemic outflow. Endovenous balloon occlusion offers a means of temporarily occluding systemic venous outflow to allow for more complete sclerotherapy. This study reviews our experience of implementing this technique in patients with Puig advanced (types 2 through 4) VMs. Methods An IRB approved review of treated venous...
