[Mediastinal Hematoma after Intravenous Thrombolytic Therapy for Cerebral Infarction in a Patient with a History of Total Aortic Arch Replacement].

ABSTRACT

An 80-year-old male patient with a history of total arch replacement for thoracic aortic aneurysm 5 years before was introduced to our hospital with a chief complaint of chest pain. Tissue plasminogen activator (t-PA) had been administrated because of acute brain infarction. A contrast-enhanced computed tomography (CT) scan demonstrated a large hematoma in the posterior mediastinum extending from the level of distal aortic arch to the descending aorta together with left pleural effusion. On the next day after admission, CT scan revealed that the hematoma became smaller. This is a rare case of a posterior mediastinal hematoma caused by t-PA with a history of total aortic arch replacement.
