The aorta is the main blood vessel leaving the heart and providing blood flow to the rest of the body. This blood vessel is made up of many layers. In certain circumstances, a tear develops in the middle layer, which allows blood to travel down the layer, setting up two channels - the "true" lumen or opening through the blood vessel and the new "false" lumen. Aortic dissection can be a life-threatening emergency, in some situations requiring emergency surgery to repair or replace that segment of the aorta.
Division of the aorta into a number of smaller vessels.
a disease characterized by tear of aortic intima, hematoma formation and separation of the arterial wall
a life-threatening disease that must be recognised early because it is an absolute indication for emergency surgery
a medical emergency requiring immediate treatment
an abnormal separation of the walls of the thoracic or abdominal aorta
a serious condition in which a tear develops in the inner layer of the aorta, the large blood vessel branching off of the heart
a sudden catastrophic tearing of the inner most layer of the wall of the aorta, the large, main arterial vessel leaving the heart
a tear in the inner layer of the aorta , the largest blood vessel in the body
a tear in the inner layer of the wall of the aorta
a tear in the wall or lining of the aorta
The aorta, the main blood vessel leading from the heart to the rest of the body, has a wall made of three layers. Rare, the layers of the aorta can separate, much as plywood left in the rain will separate between layers. When this happens to the aorta, it is called aortic dissection. Aortic dissection is a surgical emergency and patients who suffer it are at significant risk of death. Several conditions like high blood pressure ( hypertension) and Marfan's syndrome may lead to an aortic dissection.
Aortic dissection is a tear in the wall of the aorta (the largest artery of the body). This tear causes blood to flow between the layers of the wall of the aorta and forces the layers apart. Aortic dissection is a medical emergency and can quickly lead to death, even with optimal treatment.
