Pathology definition - Abdominal Aortic Aneurysm
Abdominal aortic aneurysm
Abdominal aortic aneurysm maybe asymptomatic or present with signs and symptoms such as pulsating painless mass on the abdomen. Imaging technique may reveal the present of double lumen on the aorta.
The risk factors for developing abdominal aortic aneurysm may include coronary artery disease, hypertension, atherosclerosis, smoking, male, familial disorders, ( Marfan syndrome, Ehler Danlos syndrome) cystic medial necrosis and elderly age.
There are few forms of aneurysm which may include syphilitic aneurysm, inflammatory aneurysm and hereditary form of aneurysm.
Aneurysm usually affecting the descending aorta below the renal arteries. Aneurysm mostly affecting the areas of the wall which is weak. Atherosclerotic plaque may lead to weakness of the wall due to destruction of the tunica media. Aneurysm may also appear as localized dilation of the arteries and veins.
In emergency setting such as during the rupture of the abdominal aortic aneurysm, the patient may complain of severe abdominal pain which is tearing in nature that radiates to the back.
The treatment of abdominal aortic aneurysm may include surgical repair. Beware of the complication of abdominal aortic aneurysm such as occlusion of the mesenteric arteries, iliac arteries and renal arteries with thrombosis or emboli. Mesenteric arteries, iliac arteries and renal arteries may also ruptured.
