Objective: To explore the diagnostic features and therapeutic methods of intravenous leiomyomatosis with a potential of heart invasion.
Methods: Eight cases of cardiac involvement with intravenous leiomyomatosis treated at our hospital from November 2002 to August 2011 were analyzed and compared.
Results: Either imaging or surgery confirmed that in all 8 patients the pelvic lesions originated from the inferior vena cava and heart involvement without pulmonary embolism. In 3 cases, palpitations and chest tightness were noticed. Four cases showed lower extremity edema and abdominal distension while no obvious clinical symptom was found for 1 case. All 8 cases had a history of uterine fibroids and 6 underwent previous hysterectomy. Among 8 patients, there were 5 cases of cardiopulmonary bypassing right heart, inferior vena cava tumor resection and pelvic involvement vein ligation and 2 cases of routine off-pumping of inferior vena cava with pelvic tumor resection. Palliative therapy was administered in 1 case. Two patients were resection the right heart and inferior vena cava tumor in the cardiopulmonary bypass, 3 months later were resection gynecologic uterine, double-accessories and broad ligament and were not treated with hormone. After operation, another 5 surgery patients received high-dose hormone treatments. 2 cases of recurrence in each group were found by ultrasound follow-ups from 15 - 90 months.
Conclusion: Invasion of the heart intravenous leiomyomatosis is a rare case, which can be tackled with a good effect by completely surgical resection and a limited effect on hormone therapy to prevent recurrence.
