The use of tunneled dialysis catheters to deliver hemodialysis treatment may be associated with major problems. For this reason their use should be minimized as much as possible. Infection is the most serious of these problems. This complication causes very significant morbidity and mortality and has emerged as the primary barrier to long-term catheter use.(More)
The relationship between bulk cellular myo-inositol content and phosphatidylinositol metabolism was evaluated in a human mesangial cell line under euglycemic and hyperglycemic conditions. Mesangial cells maintained in high glucose medium displayed a concentration-dependent fall in myo-inositol as measured by gas-liquid chromatography. Measurements of(More)
Data derived from a large cohort of hemodialysis patients (12,896) undergoing dialysis access maintenance procedures being performed by interventional nephrologists were analyzed to determine the safety of sedation/analgesia (S/A) in a freestanding facility. Data collected included patient demographics, procedures performed, time of procedures, drugs used,(More)
As with any type of medical procedure, endovascular procedures result in procedure-related complications (PRCs). A PRC system as part of an outcome-based practice monitoring strategy is essential. Such a program should have several features. It should be realistic, it should be standardized, it should have credibility, it must allow for comparisons with(More)
Dialysis vascular access (DVA) care is being increasingly provided in freestanding office-based centers (FOC). Small-scale studies have suggested that DVA care in a FOC results in favorable patient outcomes and lower costs. To further evaluate this issue, data were drawn from incident and prevalent ESRD patients within a 4-year sample (2006-2009) of(More)
The number of dialysis access procedures performed by interventional nephrologists using a mobile C-arm fluoroscopy machine in freestanding centers continues to rise. With this activity comes the risk of radiation exposure to patients being treated and staff. This study was conducted to assess the levels of radiation dosage involved with these procedures.(More)
A surgical site infection (SSI) is an infection related to surgery that develops within 30 days after an operation or within 1 year of implant placement. Postoperative SSIs are the most common health-care-associated infections, occurring in up to 5% of surgical patients. Endovascular surgical procedures related to vascular access are common in the dialysis(More)
A case is described in which an excimer laser is used to assist angioplasty of a severe central venous lesion that is refractory to conventional techniques. Modern laser technology uses the ultraviolet (UV) spectral region to generate nanosecond pulses of energy. This results in photoablation, which is the process by which energy photons cause molecular(More)
BACKGROUND AND OBJECTIVES Marked changes occurred in the vascular access profile of patients receiving hemodialysis in the United States over the 15-year period of 2001-2015. This study was undertaken to evaluate how these changes have affected dialysis access maintenance and salvage procedures performed in freestanding dialysis access centers and to(More)
