Ovarian and Internal Iliac Vein Embolization as a Treatment of Pelvic Congestion Syndrome
Pelvic congestion syndrome (PCS) is a condition of chronic pelvic pain of variable location and intensity that lasts for six or more months. It can be associated with persistent low-back pain, vaginal discharge, dyspareunia, postcoital pain and is aggravated by standing. PCS occurs when valves in the veins of the pelvic region leak and cause blood to flow backward and pool in the veins. Blood pooling in pelvic or ovarian veins may cause engorgement or thrombosis, leading to pain and discomfort. Risk factors associated with PCS include congestion of veins in the lower extremities, hormonal imbalance, multiple pregnancies, and polycystic ovarian disease.
Initial treatment includes psychotherapy and medical therapy (e.g., nonsteroidal anti-inflammatory drugs) and hormonal therapy. For individuals who fail initial therapy, surgical ligation of the ovarian vein may be considered. Embolization therapy of the ovarian and internal iliac veins has been proposed as an alternative to surgical ovarian vein ligation. Vein embolization can be performed using a variety of materials including coils, glue and gel foam.
Ovarian and internal iliac vein embolization for the treatment of pelvic congestion syndrome is considered investigational.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
It is difficult to draw conclusions from the current data due to a lack of placebo control or comparative data from alternative interventions. Moreover, definitions of pelvic congestion syndrome vary, making it challenging to clearly define a patient population with symptoms arising from pelvic congestion. Randomized controlled trials using well-defined eligibility criteria are needed. The evidence is insufficient to determine the effects of the technology on health outcomes.
