Abstract
Pelvic venous circulation is complex and the pathophysiology remains poorly understood. Pelvic venous disorders is the general term for a variety of syndromes caused by venous stasis in the pelvic region, including pelvic congestion syndrome, May-Thurner syndrome, and Nutcracker syndrome. Because these syndromes have been named after specific symptoms and have been treated separately by various departments, pelvic venous disorders have not been systematically treated or studied. Generally, women who has given birth with pelvic venous dilatation are often asymptomatic. However, the symptoms may vary depending on the site of venous reservoir, and it is fact that a standardized treatment plan is not possible. The Symptoms-Varices-Pathophysiology (SVP) classification proposed by the American Vein & Lymphatic Society is an attempt to comprehensively understand pelvic venous disorders based on symptoms, varices, and pathophysiology. In this article, we will discuss the usefulness of the SVP classification based on our own experience.
