腫瘍からの出血で心タンポナーデをきたした心臓血管腫の1例

Acute Cardiac Tamponade Caused by Hemorrhage from Cardiac Hemangioma：Report of a Case

はじめに　心臓血管腫は心臓腫瘍全体の約3％を占める良性腫瘍であるが，失神や突然死などの症例が報告がされている1）．われわれは，腫瘍からの出血で心タンポナーデを発症し，緊急手術となったまれな症例を経験したので，文献的考察を加えて報告する．

A 68-year-old man with acute chest pain was transported into the emergency room in our hospital. He was in shock, with a systolic blood pressure of 63 mmHg and a heart rate of 115 beats per minute. Echocardiography revealed a cardiac tamponade, but no signs of acute aortic dissection were found by computed tomography. He immediately underwent pericardial fluid drainage and was transferred to the operation theatre. Pericardiotomy was performed and hemorrhage from the right atrium was found. Then, a mass of 35 mm in diameter was also detected by transesophageal echocardiography. Resection of the right atrial tumor was performed under cardiopulmonary bypass. A bovine pericardial patch was used for the repair of the defect in the right atrium. The pathological diagnosis was cardiac hemangioma with no malignant signs.
