Temporary Clamping of Uterine and Ovarian Vessels During Minimally Invasive Myomectomy

Official title: Impact of Uterine and Ovarian Vessel Occlusion on Blood Loss in High Burden Minimally Invasive Myomectomy.

Run by The University of Texas Health Science Center, Houston · NCT07182045 · Data updated 2026-11-12

This study tests whether temporarily blocking blood flow from the uterine and ovarian arteries during minimally invasive myomectomy reduces blood loss for patients with large or multiple fibroids.

Is this trial a fit for you?

Likely a good fit

Adults undergoing minimally invasive myomectomy for a single fibroid >5 cm or multiple fibroids (≥5) without pregnancy or other exclusions.

Probably not a fit

Patients with fibroids not requiring MIS or in whom vascular occlusion is not beneficial may not see a reduction in blood loss.

What this trial studies

This interventional study investigates whether placing temporary clamps on the uterine and utero-ovarian arteries during minimally invasive myomectomy can lower intraoperative blood loss in patients with a high fibroid burden. The approach builds on existing evidence supporting reduced blood loss with vessel occlusion techniques and aims to specifically evaluate outcomes in high-burden cases. Eligible participants include adults undergoing MIS myomectomy for large intramural or submucosal fibroids or multiple fibroids, excluding those with pregnancy, under 18, concurrent gynecologic procedures, or suspected malignancy. The study will compare outcomes with and without the temporary vascular occlusion during the procedure. The lead sponsor is The University of Texas Health Science Center, Houston, at Memorial Hermann Hospital.

Why it matters

Potential benefit: If successful, patients may experience less blood loss during surgery and potentially smoother recovery.

How similar studies have gone: Prior vascular occlusion approaches have suggested reduced blood loss, but this study specifically targets high-fibroid-burden cases.
