Abstract:
A 46-year-old male developed a Stanford type B aortic dissection. At age 48, he underwent left open thoracic descending aorta replacement because of the enlargement of the descending thoracic aorta. At 51 years old, he underwent abdominal aorta replacement because of ischemia in the right lower extremity and the enlargement of an abdominal aortic aneurysm. The septum between the true and false lumens was submitted to histopathological examination, which revealed bilateral intimal tissue with the tunica media lying in between.
