[On the classification of dissecting aortic aneurysms]
Insights
Aortic dissection classification is updated to include antegrade/retrograde patterns and fenestration location. This new system aids in tailoring surgical strategies for distal aortic dissecting aneurysms.

Abstract:
Aortic dissections are most commonly categorized into types A and B depending on the involvement of ascending or descending aorta based on the Stanford system and into types I, II and III using DeBakey classification. The latest classification was proposed by the European Society of Cardiology in 2001. The authors present their own classification of distal aortic dissecting aneurysms that takes into account antegrade and retrograde dissection of the aorta, besides localization of proximal fenestration. Surgical strategies for the treatment of different variants of aortic dissecting aneurysms are considered.

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...
