dissection occurs when a small tear develops in the wall of the aorta. The tear forms an additional pathway for
blood flow within that section of the aorta and causes the layers of the aorta
to separate and weaken. In some cases,
the tear can extend through all layers of the aorta resulting in massive blood
loss or death. Chronic high blood pressure, Marfan Syndrome or atherosclerosis may increase your risk for aortic dissection.
Surgical treatment for aortic
dissection involves the removal of the most severely damaged portion of aorta
and replacement of the damaged section with a graft. An alternative, minimally invasive approach
referred to as thoracic endovascular aorta repair, is with the use of a stent
graft. This type of graft is inserted, via
catheter, inside the damaged portion of the aorta to strengthen it and prevent
blood from flowing between the layers of the aortic wall.
