title: A surgical case report of off-pump onlay patch grafting for pseudoaneurysm with diffusely calcified coronary artery.
abstract: Coronary pseudoaneurysm usually occurs after catheter-based intervention as a result of traumatic dissection or perforation of a coronary artery in 4%-5% of cases. Here, we report the successful case of pseudoaneurysm occurring after percutaneous coronary angioplasty (PTCA) against the severely calcified coronary artery treated with off-pump long onlay patch bypass technique using internal thoracic arteries. We report the case of a 59-year-old woman treated with off-pump onlay patch grafting for pseudoaneurysm after coronary angioplasty against the diffusely calcified coronary lesion. The portion of the endoarterectomized left anterior descending coronary artery proximal to the resected aneurysm extending 5cm distally was successfully reconstructed with long onlay patch using the internal thoracic arterial graft.
