Type B Aortic Dissection
Treatment of type b aortic dissection may include. It occurs when the upper aorta called the ascending aorta tears.
The procedure is similar to that used to correct a type a aortic dissection.
Type b aortic dissection. Type b aortic dissection the descending aorta is involved debakey type iii this system also helps delineate treatment. This more common and dangerous type involves a tear in the part of the aorta where it exits the heart or a tear in the upper aorta ascending aorta which may extend into the abdomen. Type a aortic dissections usually must be treated surgically whereas type b aortic dissections are managed medically under most conditions 9.
Type b refers to a tear in. Sometimes stents small wire mesh. This is a special case of type b dissection and should be called retro a dissection.
Type a is the most common and dangerous form of aortic dissection. This involves a tear in the lower aorta only descending aorta which may also extend into the abdomen. Long term outlook for people with dissection of the aorta.
