Definition of aneurysm in English English dictionary
An abnormal blood-filled swelling of an artery or vein, resulting from a localized weakness in the wall of the 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
(Tıp, İlaç) aneurysm is an abnormal widening or ballooning of a portion of anartery due to weakness in the wall of the blood vessel
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
A ballooning out of a segment of artery caused by disease or weakness in the vessel wall It may lead to rupture and serious or fatal bleeding
An enlargement of an artery In the case of the Marfan syndrome, an aneurysm often involves the tissue around the aortic valve
A weakness of the wall of a cardiac chamber or blood vessel Often associated with previous surgical or transcatheter interventions
a weakness in a wall of an artery, vein, or the heart, causing dilatation of that part
a sac-like widening of a blood vessel, especially an artery resulting from disease of the vessel wall
Weakness or injury to the wall of a blood vessel causing dilatation or ballooning and, in severe cases, threatening the integrity of the circulatory system resulting in hemorrhage or stroke A weakened point of an artery, vein or the heart
A balloon-like deformity in the wall of a blood vessel The wall weakens asd the balloon grow larger, and may eventually burst, causing a hemorrhage
A balloon-like deformity in the wall of a blood vessel The wall weakens as the balloon grows larger, and may eventually burst, causing a hemorrhage
a cardiovascular disease characterized by a sac-like widening of an artery resulting from weakening of the artery wall
An aneurysm in which an infectious agent, mostly bacteria grows through the wall of a blood vessel. It leads to an irreversible dilatation of an artery due to destruction of the vessel wall by infection
