Uterine Leiomyomatosis With Intracardiac Extension: One-Stage Surgical Approach.

Intravenous leiomyomatosis is a rare benign vascular tumor. Intracardiac extension is infrequently but can lead into a threating-life situation. We report a 41-year-old woman who has undergone previous hysterectomy due to uterine myomatosis and now presents with a pelvic mass contacting the venous system through the right internal iliac vein and extending up to the right pulmonary artery. Surgical resection of the pelvic mass and intravenous tumor removal was successfully performed in a single-stage approach with cardiopulmonary bypass. Patient recovered satisfactorily, being asymptomatic at hospital discharge time. One-stage surgical approach needs a multidisciplinary surgical team and needs a longer operative time than two-stage approach. However it can be a safety treatment option for patients with good general condition. Furthermore cardiopulmonary bypass guarantees a safe procedure, avoiding renal and hepatic ischemia and potential embolizations into pulmonary circulation during mass or ilio cava venous sector manipulation.
