What're the complications of aortic aneurysm?Rupture is a feared problem. Half of all persons with untreated abdominal aortic aneurysms die of rupture within 5 years. Abdominal aortic aneurysms are the 13th leading cause of death in the U.S. Peripheral embolization of clot within the
aneurysm can occur when a piece of clot comes loose and travels further out in the arterial system. This clot fragment can lodge in a smaller artery and block the flow of blood. Infection of aneurysms can occur from turbulent blood flow from the rough inner surface. Spontaneous blockage of the aorta can also occur.
The chance of rupture is low if an aortic aneurysm remains small (less than 55 mm wide measured by ultrasound). There is about a 1 in 100 chance of rupture per year for a small aneurysm. If the aneurysm is wider than 55 mm then the chance of rupture rises sharply, and the risk increases with increasing size. (Much like a balloon - the larger you blow it up, the greater the pressure, the greater the chance it will burst.)
Symptoms that an aortic aneurysm has ruptured - which is a medical emergency - include sudden, intense and persistent abdominal pain that may radiate to the back or legs, with sweatiness, clamminess, dizziness, low blood pressure, fast pulse and possible loss of consciousness. Aortic aneurysms can house small blood clots. These clots may break loose and block a blood vessel downstream from the aneurysm, causing pain or potentially life-threatening problems, such as a ministroke (transient ischemic attack, or TIA) or a full-blown stroke.
More information on aortic aneurysm and other aortic valve diseasesWhat is an aortic aneurysm? - An aortic aneurysm is a localized dilatation or aneurysm of the aorta, usually representing an underlying weakness in the wall of the aorta at that location.
What causes an aortic aneurysm? - Most aortic aneurysms occur in the abdominal aorta, the main cause being arteriosclerosis. There is a familial tendency to aortic aneurysms.
What're the symptoms of aortic aneurysm? - Most intact aortic aneurysms do not produce any symptoms. The ballooning of the aneurysm does not cause any symptoms unless it becomes large enough.
What're the complications of aortic aneurysm? - Half of all persons with untreated abdominal aortic aneurysms die of rupture within 5 years. Spontaneous blockage of the aorta can also occur.
How is aortic aneurysm diagnosed? - Aortic aneurysms can be diagnosed from their symptoms. An ultrasound scan is the easiest way to detect an aortic aneurysm.
What's the treatment for aortic aneurysms? - Medical therapy of aortic aneurysms involves strict blood pressure control. Symptomatic aneurysms require surgical treatment to prevent complications.
What's an abdominal aortic aneurysm (AAA)? - An abdominal aortic aneurysm (AAA) is a bulge in the aorta in abdomen. Most AAAs occur in association with advanced atherosclerosis.
What're the symptoms of abdominal aortic aneurysm? - Symptoms of abdominal aortic aneurysm include a pulsing sensation in the abdomen, and pain ranging from mild to severe.
How is abdominal aortic aneurysm diagnosed? - Because abdominal aortic aneurysms may not cause any symptoms at the beginning, they are diagnosed by chance during a physical examination.
What's the treatment for abdominal aortic aneurysm? - Treatment of abdominal aortic aneurysm depends upon the size of the aneurysm. Surgical treatment of abdominal aortic aneurysm is often preformed.
What is aortic valve disease? - An aortic valve disorder usually does not cause any symptoms in its early stages. Infection on an abnormal aortic valve leads to a disease called infective endocarditis.
What is aortic insufficiency? - Aortic insufficiency is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole.
What's aortic valve regurgitation? - Aortic valve regurgitation develops hen the valve leaflets fail to close properly during the heart's relaxation phase.
What causes aortic valve regurgitation? - Causes of aortic valve regurgitation include being born with a defective aortic valve, wear and tear from aging, infection of the lining of the heart.
What're the symptoms of aortic regurgitation? - Symptoms of aortic regurgitation include chest pain, excessive sweating, palpitations, shortness of breath that worsens with exertion or lying down.
How is aortic valve regurgitation diagnosed? - A doctor diagnoses aortic valve regurgitation by hearing a heart murmur or other abnormal noises when listening with a stethoscope.
What're the treatments for aortic regurgitation? - Medicines to improve the pumping action of the heart may be given to reduce the severity of the regurgitation. Valve replacement surgery is usually recommended.
What is aortic stenosis? - Aortic valve stenosis is a heart condition caused by narrowing of the aortic valve. Aortic stenosis is the inability of the aortic valve to open completely.
What causes aortic stenosis? - Congenital aortic stenosis is caused by improper development of the aortic valve in the first 8 weeks of fetal growth. Age related calcification of the valve is the most common cause.
What're the symptoms of aortic stenosis? - Symptoms of aortic stenosis include shortness of breath (dyspnea), passing out (syncope), and chest pain (angina pectoris).
How is aortic stenosis diagnosed? - Aortic stenosis is often diagnosed due to the presence of a heart murmur. The gold standard for diagnosis is an echocardiogram.
What's the treatment for aortic stenosis? - Patients with mild aortic stenosis do not require treatment. Valve replacement surgery is indicated for patients with severe aortic stenosis.
Aortic valve replacement surgery - Aortic valve replacement surgery is an open heart procedure for treatment of narrowing (stenosis) or leakage (regurgitation) of the aortic valve.
