Successful one-stage resection of intracardiac intravenous leiomyomatosis: A case report.

This case report is about a 47-year-old patient, who was diagnosed with intracardiac intravenous leiomyomatosis and received treatment at our institution. Intravenous leiomyomatosis is a rare, histologically benign, uterine neoplasm, which is characterized by non-invasive intravascular proliferation of smooth muscle cells. Intravenous leiomyomatosis arises from the myometrium and, in its most extensive form, can reach the heart via the pelvic veins and the inferior vena cava, causing hemodynamic complications. Treatment of choice is the complete resection of the tumor, even though there is no consensus on the optimal surgical approach. In this case, complete resection of the tumor was accomplished in a one-stage procedure. The patient recovered well and CT scan did not show any signs of recurrence after five months.
