RESUMO
We report the successful treatment of a rare case of chronic expanding hematoma and visceral pericardium thickening constrictive pericarditis with no history of trauma or surgery. A 70-year-old woman, who had no history of trauma or surgery was admitted for exertional dyspnea. An echocardiographic study demonstrated a mass located anterior to the right ventricle that severely compressed the right ventricle toward the ventricular septum. Enhanced chest computed tomography demonstrated pericardial calcification and a 125-mm heterogeneous mass in the middle mediastinum. A mosaic pattern was seen on T1, T2-weighted magnetic resonance imaging. Surgical resection of the mass and removal of the visceral pericardium were planned to treat heart failure and to confirm the diagnosis of the mass. The mass was old degenerated coagula. Histopathological examination confirmed the diagnosis of chronic expanding hematoma. The postoperative course was uneventful. There has been no sign of recurrence 19 months after the operation.
RESUMO
A 62-year-old man with Marfan syndrome had a modified Bentall procedure and total arch replacement for annuloaortic ectasia, aortic insufficiency and thoracic aortic aneurysm fifteen years ago at another hospital. A follow-up CT revealed bilateral coronary artery aneurysms and an aortic root pseudoaneurysm, and thus he was referred to our hospital. The previous prosthetic valve was removed, followed by the re-Bentall procedure. Coronary artery aneurysms were resected and consequently coronary arteries were reconstructed directly. Although the shortcoming of the Bentall procedure was pseudoaneurysm, the outcomes of the modified Bentall procedure have shown some improvements. However, as there is still a high risk of postoperative complication in connective tissue diseases, long-term follow-up is required.
