An abdominal aortic aneurysm is abnormal dilatation of the abdominal aortic trunk to 1.5 times is normal diameter (The word “aneurysm” is derived from the Greek “aneurysma” meaning “widening”). These “widenings” tend to develop, typically, within the tunica media of the arterial wall. This degeneration of the media hinders smooth muscle cell function causing widening of vessel lumen and loss of structural integrity.
This aneurysm commonplace occurs just below the level of the renal arteries and above the bifurcation of the common iliac arteries. Rupture of the vessel wall may occur causing severe hemorrhaging into the abdominal cavity. More than 80% of people who have a ruptured abdominal aneurysm will expire. It is vitally important for those at risk to receive frequent and watchful monitoring, especially as they age. click here for more details of aortic aneurysm screening ireland
There are several symptoms that may present with this condition but it isn’t uncommon for a person to present with no symptoms at all. Abdominal aneurysms occur predominately in men over 60 who have a history of tobacco smoking. They are attributed with atherosclerosis and the vast majority present as asymptomatic. Currently, ultrasound screening seems to be the most effective preventative diagnostic measure.
