[A case of aortic dissection after the termination of cardiopulmonary bypass]

We report, a case of aortic dissection after the termination of cardiopulmonary bypass (CPB), which was diagnosed by transesophageal echocardiography (TEE). A 70-year old male with aortic regurgitation received aortic valve replacement. After the termination of CPB, the aortic dissection was diagnosed by TEE. Furthermore wall motion abnormality was found by TEE, and aorto-coronary bypass was performed after observation by TEE. This case report suggests that TEE is useful not only for diagnosis but also for therapeutic orientation of aortic dissection.
