Atherosclerosis, throm number of important vascular disorders that are encountered in bosis, hypertension, and their clinical sequelae, including clinical practice, including aortic aneurysms and dissection, myocardial infarction, disabling claudication, limb loss, and peripheral arterial occlusive disease, renovascular hypertension, stroke, occur far too frequently. Indeed, vascular pathology in cerebrovascular disease, vasospasm, venous thromboembolism, one form or another is responsible for over one hundred billion venous insufficiency, and lymphedema. For each major vascular dollars of costs annually in the United States for medical condition, the pathophysiology, clinical presentation, associated expenses and lost productivity. conditions (eg, atherosclerosis, hypertension, and vasculitis), There have been rapid advancements in vascular biology, contemporary diagnostic testing (eg, vascular ultrasonography, pharmacology, and technology for vascular disease. Basic magnetic resonance imaging, and angiography), and therapeutic science discoveries have led to our recognition of the human strategies are discussed. One of the most perplexing issues vasculature as not simply a passive conduit, but as a complex to face the clinician is how to manage the patient undergoing organ that responds to both intrinsic and extrinsic stimuli with vascular surgery, since many of these patients have coexisting definable pathologic processes. In addition, technologic coronary artery disease. Therefore, we have devoted a chapter advances have redefined the role of imaging modalities. The to preoperative risk assessment, decision analysis, and enhanced resolution of techniques such as ultrasonography, medical management. computed tomography, and magnetic resonance angiography The chapter on vascular neoplasms logically categorizes and has enabled the clinician to accurately diagnose vascular beautifully illustrates the pathology of these blood vessel diseases noninvasively, thereby avoiding the risks inherent to tumors. We have also dedicated a chapter to Kawasaki disease, invasive procedures. As diagnostic modalities have become less an important infectious disease that affects blood vessels, invasive, therapeutic options have moved from the purely particularly in children, and one that is of growing interest surgical arena. Innovations in endovascular intervention have to clinicians. provided less invasive therapeutic strategies for patients Our understanding of vascular biology is increasing rapidly and affected by clinically significant atherosclerosis of peripheral our ability to favorably influence outcome in patients with vascular and renal arteries. Endovascular placement of stented grafts is disease has never been greater. This atlas is designed to provide the now employed for selected patients with aortic aneurysms. physician with a practical and informative framework, illustrating Advances in surgical techniques coupled with perioperative the clinical options in a logical and algorithmic fashion. In addition, cardiac risk assessment and management have yielded lower it will serve as a useful teaching aid for those who educate medical operative mortality and morbidity rates and consequently students, house staff, fellows, and colleagues. It is hoped that this improved the outcome for patients with arterial aneurysms, atlas will enable the readers to deal effectively with a broad range ischemic extremities, and cerebrovascular disease. of vascular diseases that are encountered in practice.

Halperin, and Mark A. Creager The aorta is the body's major conductance vessel, through which all oxygenated blood passes. As an elastic artery, the aortic wall consists of three layers: intima, media, and adven titia. The arteries arising along its course give rise to the vasa vasorum, which supply a capil lary network to the adventitia and media of the thoracic aorta; however, vasa vasorum do not supply the media of the abdominal aorta. Systolic ejection of blood from the left ventricle creates a pressure wave that traverses the aorta producing radial expansion and contraction and transfer of energy to the aortic wall. During diastole, the aortic wall recoils, transforming potential to kinetic energy and driving blood into the peripheral vessels. The term aneurysm originates from the Greek aneurysma, for dilation. The pathologic concept is distinct from ectasia, the modest generalized arterial dilation that normally accompanies aging. Aneurysms may be classified anatomically or etiologically; true aneurysms may be either fusiform or saccular. The limited orifice of a saccular aneurysm may protect the thin wall from aortic pressure, thereby reducing the risk of rupture, while the entire circumference of a fusiform aneurysm is exposed to distending forces. Infrarenal aortic aneurysms, the most common type, are almost exclusively fusiform. Aneurysms are classified according to the segment of aorta affected, since clinical features depend largely on location. Aneurysms of more peripheral arteries carry a lower risk of rupture than those of the aorta, but a greater propensity to thromboembolic complications. A pseudoaneurysm, or false aneurysm, is essentially a contained arterial rupture, in which the wall of the aneurysm is composed of thrombotic material; the relatively narrow communication between the sac and main lumen may resemble a saccular true aneurysm. Dilatation of the aorta may occur as a consequence of aging, as well as of atherosclerosis, infection, inflammation, trauma, congenital anomalies, and medial degeneration. The patho logic changes that accompany these conditions cause the aorta to thicken, thin, bulge, tear, rupture, stenose or dissect, or be altered by combinations of these conditions. Atherosclerotic lesions occur more extensively in the abdominal aorta than in any part of the arterial tree and initially affect only the intima, but fibrocaIcific degeneration leads to secondary atrophy of the medial layer. The ascending aorta is generally spared by atherosclerosis until the most advanced stages, and aneurysmal disease of the ascending aorta is more often nonathero- sclerotic.
