What is the classification of the aortic dissection?
In the Stanford classification of aortic dissection: Type A involves the ascending aorta and may progress to involve the arch and thoracoabdominal aorta. Type B involves the descending thoracic or thoracoabdominal aorta distal to the left subclavian artery without involvement of ascending aorta.
What is the difference between Stanford and DeBakey classification systems?
The DeBakey classification divides dissections into 1-5: type I: involves ascending and descending aorta (= Stanford A) type II: involves ascending aorta only (= Stanford A) type III: involves descending aorta only, commencing after the origin of the left subclavian artery (= Stanford B)
What is Stanford classification?
Stanford Classification. The Stanford classification divides aortic dissection into two groups, A and B: Group A – includes DeBakey Types I and II and involves the ascending aorta and can propagate to the aortic arch and descending aorta; the tear can originate anywhere along this path.
How many types of aortic dissection are there?
Are there different types of aortic dissection? There are two main types: Stanford Type A Aortic Dissection: This type of dissection occurs in the first part of the aorta, closer to the heart, and can be immediately life-threatening.
What is the difference between Type A and B aortic dissection?
Type A which is the more common and dangerous of the two and involves a tear in the part of the aorta where it exits the heart or a tear in the upper, or ascending aorta, which may extend into the abdomen. Type B which involves a tear in the lower, or descending, aorta only, which may also extend into the abdomen.
What is the difference between Type A and Type B dissection?
Aortic dissections are classified into two types: type B dissection involves a tear in the descending part of the aorta and may extend into the abdomen, whereas type A dissection develops in the ascending part of the aorta just as it branches off the heart.
Is aortic dissection the same as aortic aneurysm?
An aortic aneurysm occurs when a weak spot in the wall of the aorta begins to bulge, as shown in the image on the left. An aneurysm can occur anywhere in the aorta. Having an aortic aneurysm increases the risk of a tear in the aortic lining (aortic dissection), as shown in the image on the right.
What is a type 3 aortic dissection?
A “complicated” Type III aortic dissection is defined as one that causes malperfusion of the viscera, kidneys or lower extremities, or as evidenced by rupture and occurs in 25–40% of cases.
Which is worse Type A or Type B aortic dissection?
Type A Aortic Dissection Type A is the most common type of aortic dissection and is more likely to be acute than chronic. This makes it more dangerous than type B dissections because it is more likely to cause the aorta to rupture, leading to a potentially fatal heart condition.
Which arm has a higher blood pressure in aortic dissection?
After being admitted to the Intensive Care Unit, the mean arterial pressure on the left arm was noted to be significant higher. On physical examination, both lower limbs were dusky in appearance because of poor perfusion.
