Abstract

Vascular malformations (VMs) are a heterogeneous group of arterial, venous, capillary, and/or lymphatic networks that typically are present at birth and grow with the patient. Signs and symptoms associated with VM range from absent to severe, with a broad spectrum of pain, cosmetic disfigurement, and local tissue destruction. Treatment options for these malformations extend from observation to surgical reconstruction. Each treatment modality has a role in the management of vascular anomalies, but also has specific challenges. Observation is not always sufficient, medical therapies may only be available for a subset of patients and are ultimately not curative, and surgical excision may itself be disfiguring or incomplete/not definitive. Sclerotherapy and/or embolotherapy have become a cornerstone of treatment for many types of VMs. These techniques are applicable to a wide range of VMs, are less invasive, have a shorter recovery period, and are repeatable. Although some VMs may not be amenable to percutaneous or endovascular treatment given their location, and multiple sessions may be required for select large and complex VMs, these minimally invasive treatments are often first line and may be definitive in treating VMs. Various agents may be used in sclerotherapy and embolotherapy, each with their own risks and benefits. Although there is a paucity of Level 1 evidence supporting the superiority of one agent over another, longstanding case series and expert experience exist, informing our knowledge of the safety and efficacy of sclerotherapy and embolotherapy. A brief overview of the most used sclerotherapy and embolotherapy agents and their uses is provided.
