Arch replacement for acute type A aortic dissection using a single fenestrated frozen elephant trunk technique

摘要

A 42-year-old man who presented with back pain and paralysis of the left lower extremity was diagnosed with acute type A aortic dissection and transferred to our hospital for surgery. His past medical history included hypertension; however, he denied a family history of aortic disease. Contrast-enhanced computed tomography (CT) revealed type A aortic dissection with an entry tear in the transverse aortic arch and compression of the true lumen of the abdominal aorta. The patient’s vital signs were stable, however muscular weakness of the left lower extremity was noted. Transthoracic echocardiography revealed preserved left ventricular function without aortic regurgitation.
