Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are female patients aged 18 and older who have been diagnosed with pelvic congestion syndrome and are undergoing gonadal vein embolization.

Probably not a fit

Patients with pelvic congestion syndrome caused by factors unrelated to venous insufficiency or those who have had prior surgical interventions for PCS may not benefit from this study.

What this trial studies

This observational study aims to quantify the pain relief experienced by female patients undergoing gonadal vein embolization for pelvic congestion syndrome (PCS). It will also identify clinical and imaging factors that may predict a positive or poor response to the treatment. Chronic pelvic pain affects a significant number of women, and this study seeks to provide insights into the effectiveness of coil embolization as a treatment option. The study will involve patients treated at the University of Kansas Medical Center over a specified period.

Why it matters

Potential benefit: If successful, this study could provide valuable data on the effectiveness of gonadal vein embolization in relieving chronic pelvic pain for women suffering from PCS.

How similar studies have gone: Previous studies have indicated that gonadal vein embolization can reduce pain in patients with PCS, suggesting that this approach has shown promise in similar contexts.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Female patients 18 years of age or older
* Meet the clinical and imaging criteria for the diagnosis of PCS and have no contraindications to coil embolization of the gonadal veins.
* Patients who are treated with coil embolization of the gonadal veins in the Interventional Radiology division between October 1, 2018 to October 1, 2019.

Exclusion Criteria:

* Patients less than 18 years of age.
* Patients who are found to have an underlying cause of pelvic congestion syndrome unrelated to venous congestion and insufficiency. This includes, but is not limited to, nutcracker syndrome, or a mass resulting in extrinsic compression of the gonadal veins.
* Patients who have received prior surgical therapy for PCS, including bilateral salpingo-oophorectomy (TAH-BSO), gonadal vein resection, or gonadal vein ligation.
