Abstract:
Intravenous leiomyomatosis (IVL) is defined as the extension into the venous channels of histologically benign smooth muscle tumors originating either from a uterine myoma or from the walls of a uterine vessel. We report a case of IVL extending to the right atrium and right ventricle through the right internal iliac vein and the inferior vena cava. The patient was a 43-year-old woman. The tumor was extirpated by simultaneous median sternotomy and laparotomy with the use of cardiopulmonary bypass. It was necessary to use cardiopulmonary bypass in order to open the right atrium. However, it proved difficult to insert the venous cannulae into the inferior vena cava due to the presence of the tumors. In order to perform the cannulation, a trans-right atrial excision of this tumor was necessary. Nevertheless, hemodynamic deterioration tended to occur during the procedure because of unexpected bleeding. We believe that to safely carry out this operation, it would be better to ensure circulatory arrest before trans-right atrial excision of the tumor. We have been continuing preventive antiestrogen therapy because recurrence would be very likely if any tumorous tissue remained after surgery. Fortunately, no intravenous infiltration of the tumor has been detected by either pelvic computed tomography or ultrasonography during the 26-month follow-up period. Surgical excision of the tumors and postoperative medication are now believed to have been effective.
