Functionally significant, nonatherosclerotic, noninflammatory, concentric and tubular stenoses of the abdominal aorta, 4 to 16 cm in length, were encountered in five male and five female patients 11 to 49 years old. Seven patients were younger than 19 years of age. Aortic branch stenoses were common, affecting splanchnic vessels in seven patients and renal(More)
OBJECTIVE Radial artery harvesting for coronary artery bypass may lead to digit ischemia if collateral hand circulation is inadequate. The modified Allen's test is the most common preoperative screening test used. Unfortunately, this test has high false-positive and false-negative rates. The purpose of this study was to compare the results of a modified(More)
Twenty-four atherosclerotic extracranial carotid artery aneurysms were encountered in 21 patients during a 25-year period. These represented 46% of all extracranial carotid artery aneurysms diagnosed at the University of Michigan during this period. Neurologic symptoms including amaurosis fugax, transient ischemic attacks, and stroke were present in 50% of(More)
Developmental occlusive disease of the abdominal aorta and the renal and splanchnic arteries represent an unusual vascular condition. When unrecognized or untreated this disease is associated with premature death, usually from severe secondary hypertension as a consequence of renovascular stenotic lesions. Strong circumstantial evidence indicates that(More)
Despite the emphasis on surgical nutrition, clinical research and practice are usually based on gross estimation of caloric requirements and no specific knowledge of caloric balance. One reason for this is the difficulty of measuring O2 and CO2 exchange in critically ill patients. We designed a system for intensive care unit (ICU) bedside measurement of O2(More)
Noniatrogenic traumatic extracranial internal carotid artery dissections were encountered in six patients (five men and one woman) 31 to 62 years old. All but one had overt cerebral ischemia manifest by paresis (three), sensory deficits (three), aphasia (three), or amaurosis fugax (two), One patient had an asymptomatic carotid artery bruit. Cerebral(More)
Chronic total occlusion of 42 main renal arteries was documented by arteriographic studies in 25 female and 15 male patients being evaluated for drug-resistant hypertension. Arteriosclerotic lesions affected 35 patients, and fibrodysplastic obstructions occurred in five. Hypertensive urographic studies showed lateralization to the affected kidney in all 31(More)
Twenty-three patients (13 women and ten men, 33 to 73 years old) underwent reconstruction of 33 major splanchnic arteries for relief of symptomatic intestinal ischemia. All patients experienced postprandial abdominal pain and lost weight (average, 12.8 kg). Arterial reconstructions (32 bypass procedures and one endarterectomy with patch-graft arterioplasty)(More)
Nonpenetrating subclavian artery trauma, a potentially catastrophic injury, has been recognized more frequently with the liberal use of angiography in evaluating blunt cervicothoracic trauma. Six patients, five men and one woman, recently underwent surgical treatment at the University of Michigan Hospital for blunt injury of the subclavian artery. The(More)
One hundred seventy-two arteriosclerotic femoral artery aneurysms in 100 male patients, 47 to 91 years old, were evaluated. They were bilateral in 72% of the patients, and were associated with aortoiliac aneurysmal disease in 85% and with popilteal artery aneurysms in 44%. Femoral artery aneurysms were asymptomatic in 40 patients. Thirteen patients with(More)
