Abstract
Vascular malformations (VM) are classified by flow characteristics and channel content. They can involve any organ and tissue plane, and occur in focal and diffuse forms. Slow-flow vascular malformations (venous and lymphatic malformations) are typically treated by sclerotherapy, whereas fast-flow lesions (arteriovenous malformations) are managed with embolizations. Some VMs, such as VMs of the rectum or uterus, are best dealt with surgically. This review will present a summary of the conditions, their imaging features, and some useful endovascular therapeutic techniques.
