	Aneurysm - Wikipedia, the free encyclopedia
		Aneurysms most commonly occur in arteries at the base of the brain (the circle of Willis) and in the aorta (the main artery coming out of the heart) - this is an aortic aneurysm.
		While most aneurysms occur in an isolated form, the occurrence of berry aneurysms of the anterior communicating artery of the circle of Willis is associated with autosomal dominant polycystic kidney disease (ADPKD).
		For aortic aneurysms or aneurysms that happen in the vessels that supply blood to the arms, legs, and head (the peripheral vessels), surgery involves replacing the weakened section of the vessel with an artificial tube, called a graft.

	Abdominal Aortic Aneurysm [May 1996; 27-3]
		Aneurysm was defined as maximum aortic diameter of 3 cm or more.
		The prevalence of aneurysm in the screened population was higher in men than women, and highest (at about 9%) in men in their eighth decade.
		The incidence of ruptured aortic aneurysm in men over the follow-up period of five years showed a fall of more than 50% (9 of 3205 in scanned plus refused scan versus 20 of 3228 in control).

	Abdominal aortic aneurysm Encyclopedia Search - Drug Price Search
		Abdominal aortic aneurysm is an abnormal ballooning of the abdominal portion of the aorta, which is the major artery from the heart.
		Abdominal aortic aneurysm may be caused by infection, congenital weakening of the connective tissue component of the artery wall, or trauma.
		Because surgery for abdominal aortic aneurysm is risky, the surgeon may wait for the aneurysm to expand to a certain size before operating (that is, when the risk of complications exceeds the risk of surgery).

	aneurysm - HighBeam Encyclopedia
		ANEURYSM [aneurysm], localized dilatation of a blood vessel, particularly an artery, or the heart.
		An aneurysm may be asymptomatic or it may cause varying symptoms, depending upon its location and size and on whether the expanding mass is pressing on adjacent nerves or vital organs.
		Aneurysms occur most commonly in the large arteries; the aorta, the largest vessel in the body, is the one most often affected.

		An intracerebral aneurysm is a small, thin walled outpouching or dilatation of one of the large blood vessels that supply the brain.
		Aneurysms pose a risk to health from the potential for rupture and subsequent bleeding into the substance of the brain and/or the fluid-filled spaces that surround the brain (the subarachnoid space).
		The surgical clipping of an intact and accesible aneurysm is usually a procedure of low risks without the future development of postoperative ischemia or vasospasm, which are often encountered with the clipping of ruptured aneurysms (leading to risk of death or disability).

		An atrial septal aneurysm is an abnormal dilatation of the atrial septum with bulging of the septum at least half the distance to the left atrial wall.
		Atrial septal aneurysms are usually lost shortly after birth as left atrial pressure rises and eventually surpasses that of the right atrium, resulting in compression of the septum against the foramen ovale.

	Aneurysm
		An abdominal aortic aneurysm, which is usually located in the infrarenal portion of the vessel, is defined as an enlargement that exceeds the normal diameter by 50% or more.
		The lesion in the middle portion of the left anterior descending coronary artery was stented with a conventional tubular, slotted, stainless-steel stent, and the stenosis and aneurysm in the proximal portion of the artery were treated with a polytetrafluoroethylene-covered stent.
		If the aneurysm is present in the wall between the atria (the atrial septum), it is also known as an atrial septal aneurysm (ASA), an aneurysm of septum primum or an aneurysm of the septum secundum.

	Aneurysms and Dissections - Texas Heart Institute Heart Information Center
		An aneurysm occurs when the pressure of blood passing through part of a weakened artery forces the vessel to bulge outward, forming what you might think of as a blister.
		Aneurysms in the lower chest and the area below your stomach (the descending thoracic and abdominal parts of the aorta) may not be as life-threatening.
		For aortic aneurysms or aneurysms that happen in the vessels that supply blood to your arms, legs, and head (the peripheral vessels), surgery involves replacing the weakened section of the vessel with an artificial tube, called a graft.

	Brain Aneurysm and Aneurysms Information
		A brain aneurysm, also called a cerebral or intracranial aneurysm, is an abnormal bulging outward of one of the arteries in the brain.
		Brain aneurysms are often discovered when they rupture, causing bleeding into the brain or the space closely surrounding the brain called the subarachnoid space, causing a subarachnoid hemorrhage.
		The main goals of treatment once an aneurysm has ruptured are to stop the bleeding and potential permanent damage to the brain and to reduce the risk of recurrence.
