A case of in-situ reconstruction with a rifampicin-bonded gelatin-sealed woven dacron graft for prosthetic graft infection with pseudoaneurysms after ascending aortic replacement for type a dissection.

A 74-year-old woman underwent replacement of the ascending aorta for acute type A aortic dissection. The patient suffered from bacteremia postoperatively and repeated computed tomography showed an increasing diameter of pseudoaneurysms at the site of the proximal anastomosis due to graft infection. Re-mechanical Bentall operation and arch replacement were therefore performed using a composite graft of a rifampicin-bonded gelatin-sealed 24-mm woven Dacron graft and a mechanical valve. The postoperative course was uneventful. We report the successful in situ reconstruction using the above-mentioned Dacron graft and describe the preparation of the rifampicin solution using a surfactant.

Successful detection and surgical treatment of cardiac hemangioma with right ventricular invasion.

Cardiac hemangiomas are extremely rare benign tumors. These tumors are usually asymptomatic but they can present symptoms such as palpitations, shortness of breath, and arrythmia. We report the case of a 73-year-old man who presented with an abnormal shadow on chest computed tomography during follow-up for lung metastatic tumor after resection of his rectal cancer. A cardiac tumor was detected, and surgical resection and right ventricular plasty were successfully performed with the patient under cardiopulmonary bypass. Histopathologic examination revealed a benign cardiac hemangioma, which was categorized as a hemangioma of the mixed cavernous and capillary type.
