An abnormal blood-filled swelling of an artery or vein, resulting from a localized weakness in the wall of the vessel
(Tıp, İlaç) aneurysm is an abnormal widening or ballooning of a portion of anartery due to weakness in the wall of the blood vessel
Blood-filled protrusion in the wall of a blood vessel (usually an artery, and particularly the aorta). Disease or injury weakens the wall so that normal blood pressure makes it balloon out. Typically, the two inner layers rupture and the outer layer bulges. In a false aneurysm, all three layers rupture and surrounding tissues hold the blood in place. Symptoms vary with size and location. Aneurysms tend to enlarge over time, and blood-vessel walls weaken with age. Many aneurysms eventually burst, causing serious, even massive, internal bleeding; aortic aneurysm rupture causes severe pain and immediate collapse. Rupture of an aneurysm in the brain is a major cause of strokes. Treatment can consist of simply tying off a small vessel; more serious aneurysms require surgery to replace the diseased section of artery with a plastic graft
An abnormal blood-filled dilation of a blood vessel resulting from disease of the vessel wall
An abnormal balloon-like bulging of an artery's wall that can cause a hemorrhagic stroke (if the aneursym is in the brain) or life-threatening loss of blood
A balloon-like sac in the wall of an artery, vein, or heart caused by a weakening of the wall by injury, disease, or abnormality present at birth
A localised pathological dilatation of a blood vessel An aneurysm may be congenital or may occur secondary to weakness of the blood vessel wall due to cardiovascular disease (atheroma etc )
An abnormal, balloon-like bulging of the wall of an artery The bursting of an aneurysm in a brain artery or blood vessel causes a hemorrhagic stroke
