PURPOSE This study was undertaken to characterize the contemporary surgical treatment of pediatric renovascular hypertension. METHODS A retrospective analysis was conducted of the clinical data of 97 consecutive pediatric patients (39 girls, 58 boys), aged from 3 months to 17 years, who underwent operation at the University of Michigan from 1963 to 2006.(More)
OBJECTIVE Abdominal aortic coarctation is uncommon and often complicated with coexisting splanchnic and renal artery occlusive disease. This study was undertaken to define the clinical and anatomic characteristics of this entity, as well as the technical issues and outcomes of its operative treatment. METHODS Fifty-three patients, 34 males and 19 females,(More)
Monocyte adhesion to shear stress-activated endothelium stands as an important initial step during arteriogenesis (collateral artery growth). Using multiple approaches, we tested the hypothesis that monocyte adhesion via intercellular adhesion molecule-1 (ICAM-1) and selectin interactions is essential for adaptive arteriogenesis. Forty-eight New Zealand(More)
Lipopolysaccharide and D-galactosamine induced lethality and apoptotic liver injury is dependent on endogenously produced tumor necrosis factor (TNF)-alpha. The present study was undertaken to determine whether membrane-associated or secreted TNF-alpha signaling through the p55 or p75 receptor was responsible for survival and hepatic injury after(More)
IL-10 is a pleiotropic cytokine that acts as an important regulator of macrophage, T cell, and natural killer cell functions. Human IL-10 (hIL-10) has both stimulatory and inhibitory effects on a wide variety of cell types. Viral IL-10 (vIL-10) possesses only a subset of hIL-10's activities, predominantly its suppression of cytokine synthesis by T helper(More)
Current plasma markers for diagnosis of deep venous thrombosis (DVT) allow for exclusion of the diagnosis, but lack adequate specificity to establish the diagnosis. Thus, a prospective study was performed to determine the sensitivity and specificity of plasma assays for D-dimer, soluble P-selectin (P-selectin), and total microparticles in patients with(More)
BACKGROUND Arteriogenesis serves as an efficient mechanism for flow restoration after arterial occlusion. This process is associated with inflammatory mediators such as tumor necrosis factor-alpha (TNF-alpha), although their role in arteriogenesis remains unclear. We hypothesized that arteriogenesis is reduced in mice lacking functional TNF-alpha or p55(More)
OBJECTIVE The combination of D-dimer and Wells score can exclude, but not confirm, the diagnosis of deep venous thrombosis (DVT). Since thrombosis and inflammation are interrelated, we evaluated the combination of soluble P-selectin (sPsel) with other inflammatory biomarkers for the diagnosis of DVT. METHODS Sixty-two positive and one hundred and sixteen(More)
INTRODUCTION Although the natural history and management of infected open abdominal aortic aneurysm (AAA) repair is well described, only sporadic case reports have described the fate of patients with infected endografts placed in the abdominal aorta. The present study describes a tertiary referral center's experience with infected endovascular aneurysm(More)
BACKGROUND Tumor necrosis factor-alpha (TNF-alpha) and interleukin 1 (IL-1) are proximal inflammatory cytokines that stimulate expression of adhesion molecules and induce synthesis of other proinflammatory cytokines. In addition, TNF-alpha and IL-1 influence vascular smooth muscle cell migration and proliferation in vitro. In view of the inflammatory nature(More)
