What is a Type B aneurysm?

What is a Type B aneurysm?

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.

What is Stanford classification?

Answer. The Stanford classification divides dissections into 2 types, type A and type B. Type A involves the ascending aorta (DeBakey types I and II); type B does not (DeBakey type III). This system helps to delineate treatment.

What are the odds of surviving aortic dissection?

Prognosis for Aortic Dissection Hospital mortality rate for treated patients is about 30% for proximal dissection and 10% for distal. For treated patients who survive the acute episode, survival rate is about 60% at 5 years and 40% at 10 years.

Is an aortic tear the same as an 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 the most widely used aneurysm classification?

The more commonly used system is the Stanford classification, which is based on involvement of the ascending aorta and simplifies the DeBakey classification.

Can you survive an aortic dissection?

Aortic dissection is life threatening. The condition can be managed with surgery if it is done before the aorta ruptures. Less than one half of people with a ruptured aorta survive. Those who survive will need lifelong, aggressive treatment of high blood pressure.

What are the odds of surviving an aortic dissection?

Can you survive an aortic dissection without surgery?

The well-known complications of acute type A aortic dissection, for example, intrapericardial rupture, acute aortic valve insufficiency, coronary ischemia, and branch vessel occlusion, are often lethal without prompt surgical intervention.

What is the life expectancy after repairing an aortic aneurysm?

On average, patients who underwent repair for a ruptured aneurysm lived 5.4 years after surgery. Researchers found no significant differences in relative five-year survival rates between men and women or between age groups. However, researchers found differences in the repair of intact aneurysms.

What size aneurysm requires surgery?

When the aneurysm grows to 5-6 cm, the annual risk increases to as much as 12% per year, and at 7cm it exceeds 25% per year. Given these risks, surgery is usually recommended for patients with aneurysms 5-5.5cm in diameter. Once an aneurysm reaches 5 to 6 cm in diameter, the risk of rupture is very high.

How long does it take to repair an aortic aneurysm?

The aortic aneurysm repair or surgery itself will take one to two hours depending on the type of repair and complications associated with the patient. Doctors recommend for the AAA i.e. abdominal aortic aneurysm repair surgery to provide an effective treatment of aortic aneurysm.

What is the recovery time for aortic aneurysm surgery?

Recovery time following thoracic aortic aneurysm surgery varies based on the size and location of the aneurysm and on the length of the operation. Most people need at least four to six weeks to recover from the surgery.
