Of all aortic disruptions diagnosed, the majority are found at which location?

The majority of aortic disruptions are found at the isthmus. This location, situated between the left subclavian artery and the ductus arteriosus or ligamentum arteriosum in adults, is a common site for aortic injuries due to its anatomical features. The isthmus has relatively less surrounding tissue support, making it more susceptible to traumatic events, particularly in high-impact situations like vehicular accidents or falls from heights.

The isthmus is also less mobile than other segments of the aorta, which contributes to its vulnerability during significant mechanical forces. Additionally, injuries at this location can quickly lead to significant hemorrhage and complications, often requiring prompt surgical intervention.

Other regions of the aorta have different characteristics and risks, making the isthmus stand out as the location where most disruptions occur. Understanding the anatomical predispositions of the aorta can be crucial for effective diagnosis and management of aortic injuries.
