Which type of dissection involves the entire thoracic aorta including the ascending part?

Type I DeBakey dissection is characterized by the involvement of the entire thoracic aorta, including the ascending aorta, and extending beyond it. This type of dissection begins in the ascending aorta and can extend downwards to include the aortic arch and the descending aorta.

This classification is important in clinical practice because it informs the urgency and approach for surgical intervention. In cases of Type I dissection, the involvement of the ascending aorta indicates a higher risk of complications such as rupture or cardiac tamponade, necessitating prompt surgical management.

Understanding the nuances of the DeBakey classification, including Type I's comprehensive effects, helps clinicians effectively assess and treat patients experiencing aortic dissections.
