Surgery is usually necessary to repair or remove the type of aneurysm you describe. An aneurysm is an abnormal widening of an artery.
Blood pumping through it stretches the weakened wall of the artery often creating a bulge.
An aneurysm can occur in almost any location but is more likely to occur in the aorta, the main blood vessel that carries blood from the heart. An aneurysm of the radial artery one of two main arteries to the forearm is uncommon. In this situation, it's important to identify the cause of the aneurysm, such as injury or infection. Aneurysms often cause no symptoms. However, an aneurysm in the wrist may lead to cold fingers or a pulsating mass at the location of the aneurysm usually at the pulse point in the wrist.
