Diagnosis and treatment of five cases with venous leiomyomatosis involving the heart / 中国综合临床

ABSTRACT

Objective:To investigate the diagnosis and treatment of intravenous leiomyomatosis involving the heart.Methods:From March 2009 to December 2018, 5 patients with intravenous leiomyomatosis with cardiac involvement were collected from The First Hospital of Lanzhou University.All patients were admitted to the hospital as space occupying lesions of right atrium.The relevant data such as echocardiography, CT and MRI were recorded.The preoperative diagnosis, surgical methods and therapeutic effect of the patients were analyzed and summarized.Results:All the 5 patients were female with an average age of (45.8±2.2) years old.Their clinical manifestations were chest tightness and shortness of breath.Three patients had a history of giant hysteromyoma.Echocardiography was performed in all patients, and 3 of them obviously extended to the inferior chamber.Cardiopulmonary bypass was established and thoracoabdominal incision was performed, and the tumors were completely resected in 5 patients, and the origin of tumors was consistent with the result of MRI in 3 cases.The tumor originated from the right uterine vein in 3 cases, and 2 cases originated from the right ovarian vein and was intubated in the femoral vein.The operation was smooth and the postoperative recovery was good.All patients were discharged smoothly.No tumor recurrence was found in pelvic cavity, inferior vena cava and heart after 1 year follow-up.Conclusion:Venous leiomyomatosis involving the heart is rare and easy to be misdiagnosed.Most of them are diagnosed as right atrial space occupying lesions.The diagnosis can be improved by echocardiography, CT and MRI before operation.The operation mode should be adjusted according to the intraoperative findings and different origins, and the tumor should be completely removed as far as possible, and combined with gynecology consultation if necessary.The short-term follow-up showed good prognosis.
