Low-Flow Vascular Malformations in the Head and Neck: Safety and Feasibility of MR Imaging-guided Percutaneous Sclerotherapy—Preliminary Experience with 14 Procedures in Three Patients

Abstract

Fourteen percutaneous sclerotherapy procedures with magnetic resonance (MR) imaging guidance were performed in three patients with low-flow vascular malformations. All targeted vascular malformation compartments were filled with sclerosing agent without complications in a mean procedural time of 29 minutes. Follow-up imaging demonstrated reduction in size of the treated portions in all patients. In conclusion, sclerotherapy with MR imaging guidance can be performed safely and allows monitoring of injection.
