Thrombectomy of the inferior vena cava from recurrent low-grade endometrial stromal sarcoma: case report and review of the literature.

摘要

We report a rare case in which a patient successfully underwent surgical removal from the inferior vena cava of a neoplastic thrombus induced by a recurrent low-grade endometrial stromal sarcoma. The patient was admitted with severe acute renal failure and a large edema on the right lower extremity. One year previously she had undergone hysterectomy and adnexectomy due to an endometrial stromal sarcoma with involvement of the tuba. Because of complete thrombosis of the right internal and common iliac veins and the inferior vena cava, she underwent thrombectomy of the inferior vena cava. The postoperative course was complicated by hydruric renal failure induced by a acute tubular necrosis. At 6-month follow-up, the patient was asymptomatic with normal renal function. The ileocaval axis was patent on magnetic resonance imaging. Only 5 cases of intracaval extension of endometrial stromal sarcoma have been reported. Surgical treatment is viable due to excellent prognosis of the low-grade endometrial stromal sarcoma (80-100% 5-year survival) and likely fatal heart failure in untreated cases.
