Intravenous leiomyomatosis of the inferior vena cava / 中华普通外科杂志

ABSTRACT

Objective To summarize the experience on the diagnosis and therapy of intravenous leiomyomatosis(IVL)of the inferior vena cava.Methods Eight IVL patients were treated in our hospital from March 1998 to April 2007. Results The diagnosis of IVL of the inferior vena cava was established histologically by biopsy during inferior vena eavagram before operation in 4 patients.Seven patients received open surgery.Except one patient dying of massive hemorrhage during operation and one IVL recurrence during follow-up,postoperative course was uneventful and an average follow-up of 29 months found no recurrence in the other five patients. Conclusion The final diagnosis of IVL of the inferior vena cava depends on venogram and biopsy,and it is an estrogen dependent tumor originating from uterus leiomyoma.Total surgical extirpation of the tumor is the only effective treatment for IVL.
