We report on a 45-year-old woman with intimal sarcoma of the pulmonary artery. She presented with a chief complaint of shortness of breath. Computed tomography (CT) of the chest showed an intraluminal hypoattenuated area extending from the main pulmonary artery into the right main pulmonary artery and bilateral lobar pulmonary arteries. She underwent(More)
We report a case of unstable angina pectoris and alcohol-related Child-Pugh class B cirrhosis. The patient was a 60-year-old man who was admitted to hospital with chest pain. He had previously been diagnosed to have Child B cirrhosis due to alcoholic liver dysfunction at 58 years of age. He also had experienced ruptured esophageal varices, moderate ascites,(More)
Aorto-esophageal fistula (AEF) is a rare complication of esophageal carcinoma. Left untreated, it may be lethal due to massive upper gastrointestinal bleeding, while open thoracic surgery is associated with high operative mortality and morbidity. In contrast, thoracic endovascular aortic repair (TEVAR) for AEF is less invasive than open thoracic surgery.(More)
BACKGROUND Many histologic classifications of thymic epithelial tumors have been reported to date, but to the authors' knowledge, none of them closely reflect the clinical behavior or prognosis of the tumor. Therefore, it is necessary to establish a biologic marker for thymic epithelial tumors. Variants of CD44 may be important in promoting tumor(More)
A case of a large primary cardiac sarcoma on the left ventricular free wall is reported. Although the definitive diagnosis of this tumor was not made preoperatively, total excision was planned for rapid diagnosis and optimal procedure. However, the operation was discontinued due to intraoperative diagnosis of malignancy. As a result, the patient suffered(More)
Moderate hypothermic circulatory arrest with selective cerebral perfusion has been developed for cerebral protection during thoracic aortic surgery. However, visceral organs, particularly the kidneys, suffer greater tissue damage under moderate hypothermic circulatory arrest, and acute renal failure after hypothermic circulatory arrest is an independent(More)
Cerebrospinal fluid (CSF) drainage is a routinely used adjunct in operation of thoracoabdominal aortic aneurysm (TAAA), which may reduce the incidence of perioperative paraplegia by improving spinal cord perfusion. Neurological complications of CSF drainage have been reported, possibly due to excessive CSF drainage, and acute subdural hematoma (SDH) in(More)
Subepicardial aneurysm is a rare complication of acute myocardial infarction (AMI) and is associated with the risk of spontaneous rupture. We present two patients with subepicardial aneurysms detected after 1 day and 6 weeks after AMI. Both lesions were successfully treated by patch repair.
Mitral valve repair is preferred to replacement in infective endocarditis, but in the active phase, it often requires extensive debridement of infected tissue and complex reconstruction. We investigated 22 consecutive native mitral valve operations during active-phase infective endocarditis. The time from initiation of medical treatment to operation was(More)
Surgical treatment is effective to exclude all infected tissue in patients with infective endocarditis. Although various techniques have been reported, it has remained a great challenge for patients with extensive infected regions. A patient with extensive bivalvular endocarditis including the aortic and mitral valve and aorto-mitral continuity is(More)
