[Leiomyosarcoma of the inferior vena cava: literature review and surgical treatment. Apropos of 2 retrohepatic localizations].

Two cases of leiomyosarcoma of retrohepatic inferior vena cava are reported. The two patients are women and are currently alive with metastases one, seven years, and the other one year postoperatively. Leiomyosarcoma of inferior vena cava s a rare tumor which has an unexplained predilection for women. Clinical symptoms are non specific and depend mostly on the segment of the vessel involved. Preoperative diagnosis is based on ultrasonography, computed tomography and cavography. Although the prognosis is poor due to local recurrence and metastasis, we recommend an aggressive approach by radical tumor resection and caval reconstruction.
