Intravenous Leiomyomatosis Extending into the Right Ventricular Cavity: One-Stage Radical Operation Using Cardiopulmonary BypassA Case Report
Department of Surgery, Division Kobe University School of Medicine 7-5-2, Kusunoki-cho, Chuo-ku Kobe, 650, Japan The authors describe a 47-year-old woman with intravenous leiomyomatosis (IVL) extending into the right ventricular cavity. This rare entity is a neoplasm originating from smooth muscle of the uterus, with vermiform extensions into the inferior vena cava. The patient underwent a one-stage operation under simultaneous sternotomy and laparo tomy, and radical excision of the tumor was successfully achieved with use of normoth ermic cardiopulmonary bypass. Although this tumor is histologically benign, it sometimes extends into the cardiac cavity and causes sudden death due to incarceration into the atri oventricular orifice. Moreover, recurrence or lung metastasis of IVL has been reported. The authors recommend a one stage-radical resection of the tumor or a two-staged operation within a short interval. In the literature, 24 surgical cases of the intravenous leiomyomatosis with intracardiac extension have been reported. The diagnosis and surgical treatment of this tumor are reviewed and discussed.
