Educational ExhibitAbstract No. 665 - Real-time MRI guided percutaneous sclerotherapy of low-flow venous malformations
Section snippets
Learning Objectives
1. To discuss appropriate patient preparation and positioning prior to real-time MRI guided percutaneous sclerotherapy 2. To become familiar with MRI sequence planning and sclerotherapy agents used for real-time MRI guided percutaneous sclerotherapy 3. To interpret MRI studies in the context of procedure planning of patients with low-flow venous malformations
Background
1. Low-flow venous malformations are congenital soft-tissue lesions that can be found throughout the body of adults and children; approximately 40% are in the head and neck. 2. Clinical symptoms are location-dependent and include pain, cosmetic defects, oral bleeding, focal thrombosis, muscle fibrosis, hemarthrosis, local compression effects, and cranial nerve palsy. 3. MRI guided sclerotherapy is an evolving and novel approach for low-flow venous malformation treatment. 4. MR imaging is used
Clinical Findings/Procedure Details
Real-time MRI guided sclerotherapy treatment of low-flow venous malformations will be explained in a stepwise approach based on our own experience. We will share our institutional experience and demonstrate a variety of cases performed with this MR based interventional technique.
Conclusions
1. MRI protocol and interpretation for planning of the procedure 2. Patient preparation prior to procedure including the need for anesthesia or conscious sedation 3. Patient positioning in the MRI magnet for MRI guided treatment 4. Real-time MRI sequences for low-flow venous malformation identification, needle placement, and treatment success assessment using sclerosant-Gadolinium mixture injections
