	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.

	eMedicine - Thoracic Aortic Aneurysm : Article by Elaine Tseng, MD
		Surgical treatment of ascending aortic aneurysms depends on the extent of the aneurysm both proximally, ie, involvement of the aortic valve, annulus, sinuses of Valsalva, or sinotubular junction, and distally, ie, involvement to the level of the innominate artery.
		Ascending aorta aneurysms with a healthy aortic valve, annulus, and sinuses of Valsalva are typically replaced with a simple Dacron tube graft from the sinotubular junction to the origin of the innominate artery, with the patient under cardiopulmonary bypass.
		The coronary ostia are reimplanted in the graft.

		Linear artifacts in the ascending aorta, seen in 44% of patients, were shown in vitro to be multiple path artifacts caused by reflection of ultrasound within the left atrium.
		CONCLUSIONS: An atherosclerotic ascending aorta is an important predictor of postoperative renal dysfunction, possibly because atheroembolism to the kidneys occurs in the perioperative period (ie, during surgical manipulation of an atherosclerotic aorta) or because the diseased aorta may be a marker of widespread atherosclerotic disease that may predispose to perioperative renal dysfunction.
		The detection of atherosclerotic plaque in the thoracic aorta by transesophageal echocardiography appears to be a marker for the identification of obstructive coronary artery disease and deserves further investigation.

		Another anatomic classification designates dissection involving the ascending aorta as type A and that confined to the descending thoracic aorta as type B. Many physicians simply refer to dissection of the ascending aorta as proximal, and that of the descending aorta as distal.

		An aortic aneurysm is the ballooning, enlargement or dilation of the aorta, the main blood vessel that carries blood away from the heart.
		The thoracic aorta consists of the ascending aorta leading up from the heart, the aortic arch and the descending aorta leading down from the heart.
		In addition to absolute size, the rate of growth of the aorta, function of aortic valve and family history of dissection are used to determine timing of elective repair.

	V. Thoracic Aortic Surgery: State of the Art and Future Developments
		Since each area of the aorta warrants special consideration because of unique factors with regard to operative indications and issues related to organ preservation, the discussion which follows will be divided to allow separate consideration of the ascending aorta, the aortic arch, and the descending thoracic and thoracoabdominal aorta.
		However, in older patients, in whom an ascending aortic aneurysm may begin above the sinotubular junction, isolated replacement of the ascending aorta, with or without a simple valvuloplasty, is an excellent option.
		The central issue in operations on the descending thoracic and thoracoabdominal aorta is the preservation of spinal cord integrity.

		Normal aortic flow in the descending aorta comprises forward flow during most of the systole, followed by late systolic and early diastolic flow reversal caused by the elastic recoil of descending aorta in the downstream.
		Reversal of the blood flow in descending aorta during most of the diastole is seen in severe aortic regurgitation.
		When classical peripheral signs of aortic regurgitation are present (indicating rapid diastolic runoff) it is always associated with halodiastolic flow reversal in the descending aorta.
