By definition, an aneurysm is swelling of the blood vessel. They commonly occur in an artery or vein after a heart attack. An aneurysm can cause a blood clot, which can lead to major damage to the heart and brain.
Identifying an aneurysm is very difficult. There are very little symptoms that can be detected. The symptoms change depending on where the artery is located:
A Thoracic aneurysm produces a dry cough; pain in the chest neck, back and abdomen. The pain may be sudden and sharp.
Abdominal aneurysm produces back pain, appetite and weight loss, and a pulsating mass in the abdomen.
Aneurysm in a leg artery causes poor circulation in the leg, with weakness and pallor or swelling and bluish color. A pulsating mass may appear in the groin or behind the knee.
Aneurysm in a brain artery produces headache, weakness, paralysis or numbness, pain behind the eye, vision change or partial blindness, and unequal pupils.
