Role of Vasa Vasorum in the Pathogenesis of Aortic Dissection

Abstract

Vasa vasorum forms a network of capillaries and veins on the outer surface of the aortic tunica media and adventitia, which plays an important role in the structure and function of the aortic wall, but it has long been argued that its dysfunction may contribute to tissue hypoxia and hypotrophy, leading to degeneration and weakening of the aortic tunica media and eventually aortic dissection. In this review, we would like to discuss the role of vasa vasorum in the pathogenesis of aortic dissection based on previous literature.
