Techniques for Embolization of the Ovarian Vein and Pelvic Reservoir

Pelvic venous disorders are a common and under diagnosed cause of chronic pelvic pain in women, presenting with chronic, noncyclical pelvic pain for greater than 6 months and the presence of pelvic varicosities. Pelvic varices and ovarian vein reflux are a strong indicator of venous origin chronic pelvic and may benefit from embolization. This most commonly occurs in multiparous, premenopausal women with symptoms of gravity dependent pelvic pain and postcoital pain. Additional causes of pelvic venous disorders include iliac vein compression, internal iliac vein reflux, and renal vein compression, however for the purposes of this article we will focus on ovarian vein insufficiency. The mainstay of treatment for pelvic venous insufficiency is Ovarian Vein Embolization and embolization of the pelvic venous reservoir. This article will focus on the patient presentation and workup, followed by a detailed summary of how to perform this procedure, current research to support treatment, possible technical challenges and complications, and finally future research priorities.
