[Adult endocardial blood cyst; report of a case].

We report herein a rare case of endocardial blood cyst (EBC) in an adult patient. A 63-year-old asymptomatic woman underwent echocardiography, which incidentally detected a cardiac tumor in the right atrium. On echocardiography, the tumor was revealed to be a 30-mm round mass with thin, hyperechogenic walls and heterogeneously hypoechogenic contents.

Reconstruction of the right ventricular outflow tract after surgical removal of a cardiac hemangioma.

An asymptomatic 73-year-old man underwent resection of a cardiac tumor arising from the right ventricular outflow tract, and reconstruction of the right ventricular outflow tract using an expanded polytetrafluoroethylene sheet. Histological examination revealed a cavernous-capillary type cardiac hemangioma, which is a very rare cardiac tumor.

A case of biatrial multiple myxomas with glandular structure.

A 45-year-old male, who had been indicated by brain magnetic resonance imaging to have cerebral infarctions, was found by echocardiography to have a tumor in the left atrium. He had experienced several of the constitutional disturbances associated with myxoma. At the ages of 19 and 35 he had had two episodes associated with embolisms, and at the later one he was diagnosed as having multiple cerebral aneurysms.

Femoral arteriovenous fistula: a complication of temporary hemodialysis catheter placement.

The femoral vein is increasingly being used as a temporary route for dual-lumen hemodialysis catheter placement because it is thought to be safer than the internal jugular or subclavian vein sites. However, several factors preclude the wider use of indwelling femoral catheters for hemodialysis, including interference with ambulation and concern over bleeding, infection, and deep thrombosis. Herein we describe a case of right superficial femoral arteriovenous fistula as a complication of the insertion of a dual-lumen hemodialysis catheter into the right femoral vein.

Acute pulmonary thromboembolism induced by prophylactic heparin use and a heparin-coated catheter: a case of heparin-induced thrombocytopenia and thrombosis syndrome.

Heparin-induced thrombocytopenia and thrombosis syndrome (HITTS) is a potentially life-threatening side effect of heparin therapy, triggered by an immune response, and has been reported to be related not only to the therapeutic use of heparin but also to heparin-coated catheters. A 45-year-old woman with intrapelvic malignancy developed an acute pulmonary thromboembolism (PE) after hysterectomy despite prophylactic heparin use. Subsequent large doses of heparin for treatment of the PE exacerbated the thrombocytopenia and, moreover, a large thrombus formed around the heparin-coated central venous catheter.
