Résumé

An 82-year-old woman fell into a state of shock during the treatment for a urinary tract infection. Computed tomography and transthoracic echocardiography revealed massive pericardial effusion. Pericardiectomy was performed in the operating room and hemorrhagic effusion was observed. Emergent sternotomy was performed, and the bleeding site was located at the posterior portion of the left ventricular outflow. We diagnosed a rupture of a left ventricular outflow tract pseudoaneurysm after infectious endocarditis. A pericardium patch closure of the pseudoaneurysm and an aortic valve replacement were performed. The patient was discharged 35 days after the operation without recurrence of infection. Left ventricular outflow tract pseudoaneurysms is an uncommon complication following infective endocarditis, aortic valve surgery or chest trauma. Transesophageal echocardiography and multidetector-row computed tomography (MDCT) is useful for identifying such lesions.

Résumé

A 65-year-old man had received closure of the entry and false lumen Stanford type B acute aortic dissection via left thoratectomy 23 years previously. The patient underwent emergency graft replacement for a ruptured aneurysm of the thoraco-abdominal aorta 10 years previously. Enhanced computed tomography (ECT) revealed that the residual aortic dissection of the distal arch and the descending aorta were dilated. Reoperation via left thoracotomy usually requires a long cardiopulmonary bypass time and intraoperative bleeding. So we selected to perform open stent-grafting through median sternotomy alone, avoiding a left thoracotomy.
