Abstract:
A 59-year-old man was admitted to our hospital with left hemiplegia. A computed tomography( CT) scan and echocardiography revealed a cerebral infarction in the right middle cerebral artery's territory, as well as a large pseudoaneurysm (4×3 cm) of the lateral left ventricular wall. The patient agreed to undergo cardiac surgery because of the high risk of rupture and recurrent cerebral infarctions. Owing to the high probability of damaging the posterior papillary muscle and coronary arteries, an extracardiac approach was used, and the pseudoaneurysm cavity was closed using double-patch repair. The patient was discharged from the hospital on the 12th postoperative day without any complications. Both postoperative CT and echocardiography showed closure of the cavity.
