What Is A Dissecting Aortic Aneurysm
Serious condition: An aortic dissection is when a tear develops in the inner layer of the aorta [which is a large blood vessel that branches from the heart] and blood enters between the inner and middle layers, causing them to separate. If the wall ruptures, then it is often fatal. If detected and treated early on, your chances of survival improves. With appropriate treatment your risk of death is 10%. ...Read moreSee 2 more doctor answers
Aortic aneurysm is a medical condition in which there is an balloon like outpouching in the wall of the aorta, which is the largest blood vessel in the body. Most commonly, this aneurysm occurs in the segment of the aorta that runs through the abdomen. Rupture can lead to massive ...Read more
Tear of the aorta: The aorta is the largest blood vessel in the body running from the heart to the top of the pelvis. It has a smooth lining and a muscular wall. A dissection of the aorta is a tear of the lining of the aorta allowing blood to pass between the lining and the wall which can cause problems in blood flow and in some cases can be life-threatening. Acute aortic dissection typically produces sharp sever. ...Read moreSee 1 more doctor answer
Hospitalization: Acute dissection of an aortic aneurysm in the chest requires emergency care. There are different types, but dissection of an ascending aortic aneurysm will fatal over 90% of the time in hours to days unless treated with emergency surgery. Acute dissection of the descending aorta may be treated with surgery or medical care depending on the circumstances, but always requires hospitalization. ...Read moreSee 1 more doctor answer
No: About 2000 new cases/yr in the US. Very high mortality. Hard to estimate actual occurrence, 1-3%of all autopsies or 1/350 cadavers. Very high mortality if ascending aorta involved. High index of suspicion, symptoms not consistent. If ascending aorta involved, emergency surgery needed. Most of descending aorta dissections can be managed medically into chronic. Periodic cat scans to monitor needed. ...Read moreSee 1 more doctor answer
Most: Most patients with a dissection aortic aneurysm have a sensation of tearing in their chest that is painful and distressing. However, between 5-15% of patients with aortic dissection have a painless dissection, making detection more difficult. Unexplained hypotension with dyspnea and heart failure usually lead to a diagnostic echocardiogram... But missed diagnosis are common in this group. ...Read moreSee 1 more doctor answer
TO THE O.R.!: Aortic dissection may be treated with medical management or emergent surgery. With the improvement of endovascular grafts, surgical repair seems more common. A vascular surgeon will advise based on anatomy and location of dissection, vessels/organs involved. I've seen a few interventional radiologists do things also. Most important is immediate evaluation! ...Read moreSee 1 more doctor answer
No: Aneurysm is the dilation of your artery that can rupture if it gets too big overtime. A dissection is when the layers of your artery separate - generally associated with traumatic injuries (blunt or sharp), it is usually an acute event. Sometimes you can see dissection when the aneurysm starts to leak. Make friend with a vascular surgeon. ...Read moreSee 1 more doctor answer
Aneurysm/Dissection: An aneurysm is an area where the aorta has ballooned out compared to the aorta below and above. The more expanded the greater the risk of rupture. Dissection is when there is a disruption of the inner layer of the aorta and blood can flow between the layers. This often will cause blockages of aortic branch vessels resulting in stroke, heart attack, and bowel/kidney infarction, etc. ...Read moreSee 1 more doctor answer
No: An aortic dissection is a tear in the lining of the aorta, causing blood to leak into the aortic wall, causing pain and possibly hemodynamic issues. An aneurysm is an enlargement of the vessel to more than 2 times its normal size. Dissections may occur in aneurysms, and may become aneurysmal, but can occur independent of each other. ...Read more
