Veno-lymphatic (slow-flow) vascular malformations typically present in children and young adults with various combinations of pain, localized dysfunction, and disfigurement. They may also bleed or result in fatal coagulopathy. The treatment is often challenging with high recurrence after surgery or traditional x-ray fluoroscopy guided sclerotherapy. This work describes our experience with 46 sclerotherapy procedures performed exclusively within a high-field interventional MRI suite, highlights the necessary technical aspects, demonstrates the safety features related to MRI guidance as compared to traditional x-ray guidance, and reports the long-term efficacy of these procedures as observed on extended follow-up durations of up to 36.1 months.
