Aneurysm

Aneurysm is an abnormal bulging along an artery or blood vessel wall. Aneurysms occur from blood pressure at places with deteriorated or thin vessel walls. Aneurysms appear like a balloon bulging out from the outer wall of the artery. Numerous genetic diseases, medical conditions or trauma may injure the artery walls making them feeble and thin.

Aneurysms are of two main kinds, intracranial (cerebral) aneurysm that progresses within the brain and aortic aneurysms that progress within the aorta, the main blood vessel transporting oxygenated blood from the heart to the body. Aneurysms frequently go undetected until they grow large enough to push on the adjoining nerves and tissues causing the blood to ooze into nearby areas (subarachnoid hemorrhage). Cerebral aneurysms may produce pain near the eyes, numbness, weakness or paralysis on one side of the face. In instances of aneurysm rupture, you may undergo a rigorous head ache, double vision, nausea, vomiting, rigid neck, and/or loss of consciousness.
