title: [Resection of Recurrent Leiomyosarcoma of the Inferior Vena Cava with Extention into the Right Atrium and Z stent implantation；Report of a Case].
abstract: 79-year-old woman, who had undergone resection of a leiomyosarcoma of the inferior vena cava(IVC)[at 68 years old], was admitted to our hospital due to local recurrence of the leiomyosarcoma with extention into the right atrium (RA). She had progressive dyspnea and bilateral edema of the lower extremities. A computed tomography (CT) scan revealed a tumor that obstructed the IVC. A transthoracic echocardiography showed a large mobile right atrial mass. To prevent sudden death, a reoperation was performed. The tumor in the IVC and the RA was resected under deep hypothermic circulatory arrest. A postoperative CT scan showed stenosis of the IVC by residual tumor, and a Z-stent was therefore implanted in the IVC. Postoperative recovery was uneventful and the patient no longer showed any symptoms.
