OBJECTIVE To examine contemporary operative techniques and outcomes for repair of isolated iliac artery aneurysms. METHODS We retrospectively reviewed the charts of all patients who underwent repair of an isolated iliac artery aneurysm from February 1995 to June 2007. Mycotic aneurysms and patients with concurrent infrarenal abdominal aortic aneurysms(More)
Clostridium septicum aortitis is a rare infection that has a strong association with occult colonic malignancy. To our knowledge, we report the 25th and 26th cases of C septicum aortitis in the English literature and make recommendations for its management. The first patient was a 75-year-old man who presented with abdominal pain. Computed tomography showed(More)
OBJECTIVE Computed tomographic angiography (CTA) is currently the most commonly used technique for postoperative surveillance to detect endoleaks after endovascular stent graft repair of abdominal aortic aneurysms. We have evaluated the efficacy of duplex ultrasound scan with the addition of an ultrasound scan contrast agent in documenting endoleaks and(More)
Permanently implantable hemodynamic monitors show great promise in providing personalized and cost-efficient care to heart failure patients by providing timely intracardiac pressure data under ambulatory conditions. The data may be used to titrate maintenance therapies and to monitor health status so that more intensive interventions can be planned and(More)
Surgeons increasingly encounter patients on clopidogrel therapy who are preparing to undergo surgery. The goal of this study was to examine the change in platelet function after the common clinical scenario of discontinuing chronic clopidogrel therapy in those patients preparing to undergo an elective surgery, and the time course of platelet function(More)
Investigating molecular mechanisms involved in the formation of carotid atherosclerotic plaques has been challenging. Isolating high-quality RNA from plaque tissue can be difficult because of acellularity, calcification, and degradation. It is essential that the mRNA isolated from this tissue preserves and reflects the actual relative gene expression. Two(More)
PURPOSE We evaluated mid-term results of a single-center consecutive series of endovascular stent-grafts implanted for aortic aneurysm repair with transrenal fixation, to determine clinical outcome, aneurysm anatomy, renal artery patency, and renal complications. METHODS Modular stent-grafts were placed with transrenal fixation in 37 patients between(More)
PURPOSE We evaluated our early experience with the transrenal fixation of aortic stent-grafts to determine the efficacy of this procedure and its effects on renal artery patency and hemodynamics. METHODS Twenty-eight patients (22 men) had endoluminally placed modular bifurcated stent-grafts with a bare spring structure at the proximal end crossing the(More)
The response of the peripheral nervous system to various dose levels of tributoxyethyl phosphate (TBOP) was investigated in Sprague-Dawley rats. Groups of randomized female and male rats (10 rats/gender/dose level) were administered a single oral dose of TBOP (1.0 to 3.2 g/kg for females; 1.0 to 9.0 g/kg for males). Physiological parameters were measured in(More)
Tri-n-butyl phosphate was administered by gavage to male and female Sprague-Dawley rats for 14 consecutive days (low dose: 0.14 ml kg-1; high dose: 0.42 ml kg-1). Effects of this chemical were investigated at the end of the feeding period. Histopathological examination of the testes (high-dose group) showed the presence of microscopic degenerative changes(More)
