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)
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)
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)
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)
BACKGROUND Hybrid visceral-renal debranching procedures with endovascular repair have recently been proposed as a less invasive alternative to conventional thoracoabdominal aortic aneurysm (TAAA) surgery. This study provides a concurrent assessment of hybrid and open TAAA repair. METHODS One hundred two consecutive patients (mean age, 63.0 years)(More)
OBJECTIVE Renal dysfunction following endovascular abdominal aortic aneurysm repair (EVAR) remains a significant source of morbidity and mortality. We studied the use of carbon dioxide (CO(2)) as a non-nephrotoxic contrast agent for EVAR. METHODS Recorded data from 114 consecutive patients who underwent EVAR with CO(2) as the contrast agent over 44 months(More)
BACKGROUND Endovascular revascularization of chronic total occlusion (CTO) of the iliac arteries is rapidly becoming first-line treatment, with surgical aortofemoral bypass procedures reserved for failure of endovascular treatment. Percutaneous subintimal recanalization is the most common endovascular revascularization technique for CTO of the iliac(More)
PURPOSE To present the techniques for endovascular treatment of thrombosed filter-bearing inferior vena cavae (IVCs), along with short-term clinical and imaging follow-up. MATERIALS AND METHODS A total of 45 consecutive patients (17 females and 28 males), aged 19-79 years (mean age of 49 years), who had IVC filter placement complicated by symptomatic(More)
