PURPOSE It is believed that cerebral hyperperfusion syndrome (CHS) is caused by loss of cerebral autoregulation resulting from chronic cerebral ischemia and that factors including increased intraoperative cerebral blood flow, ipsilateral or contralateral carotid disease, and postoperative hypertension may cause CHS. We describe our experience with CHS,(More)
INTRODUCTION Transforming growth factor-beta 1 (TGF-beta 1 ) is known to maintain a balance between apoptosis and cellular dysfunction and therefore may have a pivotal role in vessel remodeling during pathogenesis of vascular disorders. We previously demonstrated that inducible nitric oxide synthase (iNOS) mediates signal transduction in vascular wall(More)
BACKGROUND To examine the effect of office-based duplex-guided balloon-assisted maturation (DG-BAM) on arteriovenous fistula (AVF), we retrospectively analyzed our experience. METHODS Over the past 10 months, we performed 185 DG-BAMs (range, 1-8 procedures; mean, 3.7) in 45 patients (29 male, 16 female; mean age, 68.2 ± 12.8 years) with 31(More)
We have noted a significant incidence of pulmonary embolism (PE) and mortality associated with upper extremity deep venous thrombosis (UEDVT). Since there is an association between site of lower extremity DVT (LEDVT) and PE, we hypothesized that there might also be a correlation between site of UEDVT and PE with associated mortality. To further elucidate(More)
The objective of this study was to compare magnetic resonance angiography (MRA), contrast arteriography (CA), and duplex arteriography (DA) for defining anatomic features relevant to performing lower extremity revascularizations. From March 1, 2001 to August 1, 2001, 33 consecutive inpatients with chronic lower extremity ischemia underwent CA, MRA, and DA(More)
PURPOSE We have previously demonstrated that glycine has a protective effect in mesenteric ischemia/reperfusion (I/R) injury. The purpose of this study was to elucidate the molecular mechanisms of the cytoprotective action of glycine. Because oxidative stress in I/R injury can lead to apoptosis, we examined the role of glycine in modulating the apoptotic(More)
BACKGROUND The technique of long segment stenting of the superficial femoral artery (SFA) has been associated with poorer short- and long-term results. The full metal jacket (FMJ) stenting is typically described as long segment continuous stenting of a vessel segment. Initially, this technique was described in percutaneous coronary interventions. However,(More)
OBJECTIVE To elucidate the natural history of upper extremity deep venous thrombosis (UEDVT), we examined factors that may contribute to the high mortality associated with UEDVT. METHODS Five hundred forty-six patients were diagnosed with acute internal jugular/subclavian/axillary deep venous thrombosis from January 1992 to June 2003 by duplex scanning at(More)
OBJECTIVE Although anticoagulation remains the mainstay of treatment for deep venous thrombosis, the use of inferior vena cava (IVC) filters when anticoagulation has failed or when contraindicated remains a safe and effective treatment. Greenfield (Boston Scientific, Natick, Mass) and TrapEase (Cordis, Bridgewater, NJ) filters are arguably among the most(More)
PURPOSE The placement of central catheters is a common procedure. It is also associated with multiple known complications. One of the potential complications that carry high morbidity and morality is arterial puncture and cannulation. Herein, we describe five case reports of a central line that was inadvertently placed in the subclavian artery and(More)
