Primary leiomyosarcoma of the inferior vena cava necessitating radical resection and reconstructionHansel, Jan (Avtor) Mrđja, Božidar (Avtor) Flis, Vojko (Avtor) leiomiosarkomspodnja votla venaradikalna resekcijapooperativna tromboza žilne protezePrimary leiomyosarcoma of the vena cava is a rare tumor. We describe a 63-year-old female in whom a mass was found upon ultrasonographic examination of the abdomen after persistent pain in the right upper quadrant. CT and MRI revealed a malignant intraluminal growth in the inferior vena cava. Radical resection was undertaken to remove the tumor. The inferior vena cava was reconstructed using a PTFE graft. Resection margins were free of tumor. Postoperative complications included extended thrombosis below the surgical site and smaller pulmonary emboli. A vena-cava filter was inserted to prevent further complications. Twelve months after the first procedure local subcutaneous metastases were observed. Metastases were subsequently removed. We discuss our case to deepen our understanding of this extremely rare disease.Medicinska fakulteta20132015-12-30 12:30:26Znanstveno delo56834sl
