Abstract:
The wall of a true aneurysm is composed of all histologic layers of the aorta. A false aneurysm represents a small, contained rupture of aorta followed by bulging of the corresponding area that is usually sustained by a fibrous peel. Aortic dissection is defined as a separation of the lamellae of the aortic wall. Herein, we describe an unusual clinical presentation of aortic dissection in a 37-year-old male patient that presented severe aortic regurgitation and unusual bulges with linear intimal fissures in ascending aorta underwent mechanical aortic valve replacement and interposition of tubular vascular graft in ascending aorta.

The Aorta
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...
