Since the aorta branches directly from the heart to supply blood to the rest of the body, the pressure within it is very great, and blood may be pumped out of a tear in the blood vessel very rapidly . This can quickly result in shock and death.
About 40% of patients die immediately from complete rupture and bleeding out from the aorta . The risk of dying can be as high as 1% to 3% per hour until the patient gets treatment. If you have symptoms of aortic dissection, severe chest pain, or symptoms of a stroke, call 911 or seek emergency care.
If a large aneurysm bursts, it causes huge internal bleeding and is usually fatal . The bulging occurs when the wall of the aorta weakens. Although what causes this weakness is unclear, smoking and high blood pressure are thought to increase the risk of an aneurysm. AAAs are most common in men aged over 65.
An aortic dissection is a serious condition in which a tear occurs in the inner layer of the body's main artery (aorta). Blood rushes through the tear, causing the inner and middle layers of the aorta to split (dissect). If the blood goes through the outside aortic wall , aortic dissection is often deadly.
If the ruptures occur in the anterior areas, up to 90% of patients suddenly die within 48 hours if left untreated or treated improperly.
Ruptured abdominal aortic aneurysms (RAAAs) continue to be a significant cause of death in the United States. Mortality rates after repair of an RAAA have not significantly changed in the literature in the past 20 years, still ranging between 30% and 70% in the most recent reports.
Less than one half of people with a ruptured aorta survive . Those who survive will need lifelong, aggressive treatment of high blood pressure. They will need to be followed up with CT scans every few months to monitor the aort
A ruptured aneurysm can cause massive internal bleeding, which is usually fatal . Around 8 out of 10 people with a rupture either die before they reach hospital or don't survive surgery. The most common symptom of a ruptured aortic aneurysm is sudden and severe pain in the abdome
