Definition:
Dissecting aneurysm is also called an aortic dissection, characterized as a serious condition in which a tear develops in the inner layer of the aorta, the large blood vessel branching off the heart.
Diagnosis:
The widening of the aorta on chest x-ray, sudden tearing or ripping chest pain and blood pressure difference between right and left arms are among the signs and symptoms that will lead to the suspicion of doctors of an aortic dissection.
Treatment:
Immediate treatment is required for an aortic dissection since it is a medical emergency. Medications or surgery may be included as therapy, depending on the area of the aorta involved.
Symptoms and Signs:
Other heart problems such as a heart attack may be similar to the symptoms of aortic dissection. The usual signs and symptoms of aortic dissections include stroke, sudden severe chest or upper back pain, often described as a tearing, ripping or shearing sensation that radiates down the back; weakness, loss of consciousness (fainting) and shortness of breath.
Causes:
Dissecting aneurysm or aortic dissection happens in a weakened area of the aortic wall. Chronic high blood pressure may make the aortic tissue more susceptible to tearing because of stress. Aortic dissections may be caused rarely by traumatic injury to the chest area as that during motor vehicle accidents.
