	Abdominal Aorta \| World of Anatomy and Physiology
		The abdominal aorta is a region of the descending aorta, originating superiorly as a continuation of the thoracic aorta as it passes through an opening in the diaphragm, and terminating inferiorly as the abdominal aorta bifurcates (divides into two structures) into the left and right common iliac arteries.
		Lateral to the aorta are the inferior phrenics, middle supernal, renal, and ovarian or testicular arteries.
		Because the branches from the abdominal aorta are large, the aorta rapidly decreases in size as it courses downward (inferiorly) through the abdomen.

	VI. The Arteries. 5a. 2. The Abdominal Aorta. Gray, Henry. 1918. Anatomy of the Human Body.
		—The abdominal aorta is covered, anteriorly, by the lesser omentum and stomach, behind which are the branches of the celiac artery and the celiac plexus; below these, by the lienal vein, the pancreas, the left renal vein, the inferior part of the duodenum, the mesentery, and aortic plexus.
		The right is longer than the left, on account of the position of the aorta; it passes behind the inferior vena cava, the right renal vein, the head of the pancreas, and the descending part of the duodenum.
		Sometimes one is derived from the aorta, and the other from one of the renal arteries; they rarely arise as separate vessels from the aorta.

		Abdominal aorta: The abdominal aorta is the final section of the aorta, the largest artery in the body.
		Aorta: The largest artery in the body, the aorta arises from the left ventricle of the heart, goes up (ascends) a little ways, bends over (arches), then goes down (descends) through the chest and through the abdomen to where ends by dividing into two arteries called the common iliac arteries that go to the legs.

	University of Chicago Hospitals: Abdominal Aortic Aneurysm
		An abdominal aortic aneurysm, also called AAA or triple A, is a bulging, weakened area in the wall of the aorta (the largest artery in the body) resulting in an abnormal widening or ballooning greater than 50 percent of the normal diameter (width).
		The aorta extends upward from the top of the left ventricle of the heart in the chest area (ascending thoracic aorta), then curves like a candy cane (aortic arch) downward through the chest area (descending thoracic aorta) into the abdomen (abdominal aorta).
		An abdominal aortic aneurysm may be caused by multiple factors that result in the breaking down of the well-organized structural components (proteins) of the aortic wall that provide support and stabilize the wall.

	Aorta
		Recent recognition of familial clustering of patients with abdominal aortic aneurysm, the identification of genetic defects in collagen in a family with multiple aneurysms' and the detection of abnormal collagenase and elastase in tissue from aortic aneurysms resected at operation have led some to the assumption that atherosclerosis is invariably the underlying pathophysiologic mechanism.
		Dilatation of the aortic knob and descending thoracic aorta is typical of distal disease.
		For ascending aortic dissection, the procedure consists in transection of the ascending aorta with use of cardiopulmonary bypass, obliteration of the false lumen by approximation of the inner and outer walls of the false channel, and end-to-end anastomosis of the transected aorta.

	Clinics - Different patterns of atherosclerotic remodeling in the thoracic and abdominal aorta (Site not responding. Last check: )
		The objective of this study was to separately evaluate the relationship between the aortic diameter in the thoracic and abdominal segments, and the extent and histological characteristics of atherosclerosis in patients presenting with atherosclerotic disease.
		Table 1 presents age, gender, diameter of thoracic and abdominal segments of the aorta, percentage atrophy of the medial layer, and semiquantitative scores of the cases.
		In the abdominal segment, atherosclerosis is less likely to be associated with fat deposition and compensatory dilation, thus explaining the development of the obliterative form of the disease, with the significant reduction of the arterial diameter and chronic distal ischemia.

	Information on Abdominal aortic aneurysm produced by medical doctors
		An aortic aneurysm involves the aorta, one of the large arteries that carries blood from the heart to the rest of the body.
		The aorta is first called the thoracic aorta as it leaves the heart, ascends, arches, and descends through the chest until it reaches the diaphragm (the partition between the thorax and abdomen).
		The aorta is then called the abdominal aorta after it has passed the diaphragm and continues down the abdomen.

	Abdominal aortic aneurysm - abdominal aortic aneurism
		An aortic aneurysm is a general term for any swelling (dilatation or aneurysm) of the aorta, usually representing an underlying weakness in the wall of the aorta at that location.
		Aortic aneurysms commonly occur in the abdominal aorta (Abdominal Aortic Aneurysm (AAA)), where the walls are thinner.
		In individuals with Marfan syndrome, surgical treatment of an ascending aneurysm should be performed when the diameter of the aorta reaches 5cm, while treatment of a descending thoracic aneurysm should be performed when the diameter of the aorta reaches 6 cm.
