What type of aortic dissection is treated with surgical excision of the tear?

The treatment for aortic dissection classified as Stanford A involves surgical intervention, specifically surgical excision of the tear in the aorta. Stanford A dissections originate in the ascending aorta and are characterized by their potential to cause severe complications like aortic rupture or compromise of aortic blood flow to vital organs. Because of these heightened risks, immediate surgical repair is often required to address the underlying issues and ensure the integrity of the aorta.

In contrast, dissections classified as Stanford B typically originate in the descending aorta and are usually managed medically unless complications arise. The DeBakey classification further refines the categorization but aligns similarly, where DeBakey I (which involves both the ascending and descending aorta) and DeBakey II (which involves only the ascending aorta) necessitate surgical intervention, similar to the Stanford A classification. However, DeBakey III, involving the descending aorta, follows the treatment path of Stanford B.

Understanding the distinction between the various classifications and their respective treatment implications is crucial for effectively managing patients with aortic dissections.
