In Situ Replacement for a Mycotic Aneurysm on the Porcelain Aorta Using the Superficial Femoral Artery as a Vascular Graft / 日本心臓血管外科学会雑誌

Infected thoracic aortic aneurysms are rare. Standard treatment methods have not yet been established for medical treatment, timing of surgery, or surgical techniques. In this study, we report a case in which an ascending aortic reconstruction using an autologous superficial femoral artery was successfully performed for an infected pseudoaneurysm of the thoracic aorta without the use of artificial materials. The patient was a 78-year-old man with bacteremia caused by Staphylococcus aureus and an infected pseudoaneurysm of the thoracic aorta. The patient underwent replacement of the ascending aorta and coronary artery bypass grafting. The patient was discharged from the hospital with no recurrence of infection and no abnormality of the reconstructed aorta.

A Case of Primary Right Atrial Angiosarcoma / 日本心臓血管外科学会雑誌

Primary cardiac angiosarcoma is extremely rare and its prognosis remains poor. We present a 61-year-old woman with angiosarcoma who was admitted with exertional dyspnea and considerable hemodynamic compromise. Computed tomography showed a large tumor in the right atrium and multiple liver metastases. The cardiac tumor invaded from the superior vena cava to the atrial septum. After the cardiac tumor was removed, the right atrium, the atrial septum and the superior vena cava were reconstructed with a bovine pericardial patch. The pathological diagnosis was angiosarcoma, and the cut-end was positive for sarcoma. The patient survived 14 months after surgery with the aid of adjuvant chemotherapy.
