How is aortic aneurysm diagnosed?
Aortic aneurysms can be diagnosed from their symptoms when they occur but this is often too late. They are usually found on routine physical examination and chest and abdominal X-rays. On examination, your doctor may feel a pulsating mass in your abdomen which may be tender if an abdominal aortic aneurysm is large. If your doctor suspects an aneurysm, he or
she will probably request that an ultrasound scan is carried out. Other scans such as computerised tomography (CT) and magnetic resonance imaging (MRI) may also be performed: these are very useful for determining the exact position in the chest of a thoracic aortic aneurysm.
Dissecting aneurysms are diagnosed initially from their symptoms and physical examination of the pulses in the arms and legs. Other tests include chest X-rays, ultrasound scans, CT (often using injected dyes that show the flow of blood) and MRI.Sometimes a doctor feels the bulge of an aortic aneurysm during a routine examination of the abdomen. But, many aortic aneurysms are too small to feel. An x-ray of the abdomen (often done for other reasons) will show calcium deposits lining the wall of the aneurysm in some, but not all, cases.
An ultrasound scan is the easiest way to detect an aortic aneurysm. This is a painless test. (It is the same type of scan that pregnant women have to look at the baby in the womb.) The size of the aneurysm can also be measured by ultrasound. As discussed later, it is important to know the size. More detailed scans, such as a CT scan, are only needed if your doctor needs to know whether the aneurysm is affecting any of the arteries that come off the aorta. For instance, if the aneurysm involves the arteries to the kidneys then surgeons need this information if they plan to operate.
More information on aortic aneurysm and other aortic valve diseases
What 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.
