Aortic rupture is a rare, extremely dangerous condition that is considered a medical emergency. [1] The most common cause is an abdominal aortic aneurysm that has ruptured spontaneously. Aortic rupture is distinct from aortic dissection , which is a tear through the inner wall of the aorta that can block the flow of blood through the aorta to ...
Aortic dissection; Stanford type B dissection of the descending part of the aorta (3), which starts from the left subclavian artery and extends to the abdominal aorta (4). The ascending aorta (1) and aortic arch (2) shown in the image are not involved in this condition. Specialty: Vascular surgery, cardiothoracic surgery: Symptoms
Traumatic aortic rupture, also called traumatic aortic disruption or transection, is a condition in which the aorta, the largest artery in the body, is torn or ruptured as a result of trauma to the body. The condition is frequently fatal due to the profuse bleeding that results from the rupture.
Arterial dissections become life-threatening when growth of the false lumen prevents perfusion of the true lumen and the related end organs. For example, in an aortic dissection, if the left subclavian artery orifice were distal to the origin of the dissection, then the left subclavian would be said to be perfused by the false lumen, while the left common carotid (and its end organ, the left ...
Rupture is defined as a forcible disruption of tissue. Some disagree with the usage of rupture as they believe it implies that a tear is incompatible with life; however, the term accurately gauges the severity of tears in the aorta. A rupture can be either complete or partial, and can be classified further by the position of the tear. [5]
At the superior end, the ligamentum attaches to the aorta—at the final part of the aortic arch (the isthmus of aorta) or the first part of the descending aorta. [2] On the other, inferior end, the ligamentum is attached to the top of the left pulmonary artery.
Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta. [1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. [2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
Rupture of the aneurysm results in a subarachnoid hemorrhage and a very severe headache. Aortic dissection – Dissection along the length of the aorta between the layers of the aortic wall. Dissection of the ascending aorta (type A) is a surgical emergency while dissection of the descending aorta (type B) can possibly be managed medically.
