Abstract
A 74-year-old woman with massive hemoptysis and shock who had been diagnosed with thoracic aortic rupture underwent in situ replacement of the thoracic aorta using an equine pericardial roll graft. The lower lobe of the left lung was resected because of a massive hematoma and adhesion to the wall of the thoracic aorta. Intraoperative microscopic examination of the resected aortic wall revealed Gram-positive bacteria (α-streptococcus in bacterial cultivation). Histology of the resected aorta revealed abscess formation in the media and adventitia of the aortic wall associated with disruption of the media (dissection). Postoperative computed tomography revealed no fluid collection around the graft 1 month after surgery, and magnetic resonance imaging showed no significant graft dilation 20 months after operation. The equine pericardium can be an option of alternative graft materials for in situ replacement of the thoracic aorta in patients with an aortobronchial fistula due to aortic rupture.
