OBJECTIVE To define the relevance of treating renal artery aneurysms (RAAs) surgically. SUMMARY BACKGROUND DATA Most prior definitions of the clinical, pathologic, and management features of RAAs have evolved from anecdotal reports. Controversy surrounding this clinical entity continues. METHODS A retrospective review was undertaken of 168 patients (107(More)
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)
The Clinical Practice Council of the Society for Vascular Surgery charged a writing committee with the task of updating practice guidelines, initally published in 2003, for surgeons and physicians who are involved in the preoperative, operative, and postoperative care of patients with abdominal aortic aneurysms (AAA). This document provides recommendations(More)
OBJECTIVE To determine the role of CXCR2, the receptor for cysteine-X-cysteine (CXC) chemokines, and its primary effector cell, the neutrophil (PMN), on deep venous thrombosis (DVT) resolution. METHODS AND RESULTS DVT in BALB/c, anti-CXCR2 antibody-treated, and BALB/c CXCR2(-/-) mice were created by infrarenal inferior vena cava (IVC) ligation and the(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)
BACKGROUND The primary purpose of this study was to evaluate compliance, side effects, and safety associated with prolonged administration of doxycycline in patients with small asymptomatic abdominal aortic aneurysms (AAAs). A secondary goal was to determine how treatment with doxycycline influences circulating levels of matrix metalloproteinase-9 (MMP-9)(More)
First recognized in patients with rare inborn errors of metabolism, the association of elevated plasma homocysteine concentrations with atherosclerosis and thrombosis now seems relevant to the general population as well. The mechanism of injury appears to involve oxidative damage to endothelial cells. Vitamin supplementation can normalize homocysteine(More)
PURPOSE Small areas of blood flow are sometimes seen within an otherwise thrombosed false lumen on computed tomography (CT) scans of intramural hematomas of the aorta. These are blood-filled spaces that, although they have no apparent communication with the true lumen, appear isodense with the aorta on contrast-enhanced CT scans. The purpose of this report(More)
PURPOSE Small collections of contrast material are frequently seen within the otherwise thrombosed false lumen of an aortic dissection (AD). These collections can be divided into those without apparent communication with the aortic lumen (ie, pseudoaneurysms) and those with obvious communications (ie, ulcers). The present study was performed to test the(More)
Minimally invasive approaches have dramatically reduced morbidity associated with adrenalectomy. There has been concern that an increased frequency of adrenal imaging along with the advantages of less morbidity could influence the indications for adrenalectomy. We tested the hypothesis that adrenalectomy has become more common over time and that benign(More)
