Successful Complete Surgical Resection of a Large Venous Malformation of the Lower Extremity: A Case Report.

Venous malformations (VMs) are the most common type of vascular malformations, resulting from errors in vascular morphogenesis. Because of the wide variety in their presentations, selecting the appropriate treatment, especially for large VMs, may be challenging. Herein, we report a case of a 59-year-old man with a large VM in the lower extremity who achieved favorable outcomes by complete surgical resection. Even large VMs can be successfully treated with surgery when patients are properly selected. An accurate and careful evaluation is essential for achieving optimal outcome in patients with VMs.
