Aortic dissections that occur in the ascending part of the aorta are called type A; those in the descending aorta are type B. These types of dissections are further classified by two categories: acute and chronic. Doctors diagnose both type A and type B aortic dissections as being either acute or chronic.

2022年12月12日 · The Stanford classification divides aortic dissection into two groups, A and B: Type A – involves the ascending aorta and can propagate to the aortic arch and descending aorta (i.e. DeBakey Types I and II) ; the tear can originate anywhere along this path

2024年10月18日 · Both the Stanford and DeBakey systems can be used to describe all forms of an acute aortic syndrome (dissection, aneurysm, penetrating atherosclerotic ulcer, and intramural hematoma). The Stanford classification divides dissections by the most proximal involvement:

2024年10月6日 · Aortic dissections are classified anatomically by 2 systems: the Stanford and DeBakey classification systems. The Stanford system categorizes dissections into 2 types based on whether the ascending or descending part of the aorta is involved (see Image. Stanford Classification of Aortic Dissection).

2024年9月26日 · Each year, 5 to 30 people per 1 million have an aortic dissection. There are two main aortic dissection types: Stanford Type A Aortic Dissection: This type starts in the first (upper) part of your aorta, closer to your heart. It can be immediately life-threatening.

2021年8月6日 · Aortic dissections are divided into two groups, depending on which part of the aorta is affected: Type A. This more common and dangerous type involves a tear in the part of the aorta where it exits the heart. The tear may also occur in the upper aorta (ascending aorta), which may extend into the abdomen. Type B.

2024年8月7日 · Types of Aortic Dissection. There are two kinds of aortic dissections. The difference is where the dissection is located. Type A. This is the more common of the two, and more dangerous.

2024年9月28日 · Type A dissection: chest pain ~80%, back pain ~50%, abdominal pain ~20%. Type B dissection: chest pain ~60%, back pain ~60%, abdominal pain ~40%. Chest pain may radiate to the back or epigastrium.

Aortic dissections are divided into three types. The type depends on which part of the aorta is affected.

Aortic dissection reconsidered: type, entry site, malperfusion classification adding clarity and enabling outcome prediction.

There are multiple systems of aortic dissection classification. The most common is the Stanford system, which classifies aortic dissections into two types according to the location of the tear. Type A: The aorta is shaped like a candy cane or an upside-down J.
