BACKGROUND We previously reported a reduction in central venous catheter (CVC) malfunction when using once-weekly recombinant tissue-plasminogen activator (rt-PA) as a locking solution, compared with thrice-weekly heparin. OBJECTIVES To identify risk factors for CVC malfunction to inform a targeted strategy for rt-PA use. DESIGN Retrospective analysis. SETTING Canadian hemodialysis (HD) u...
RATIONALE A persistent left superior vena cava (PLSVC) is rare, but the most common thoracic venous anomaly. We report a case of PLSVC unrecognized during left subclavian vein catheterization using real-time ultrasound-guided supraclavicular approach. PATIENT CONCERNS A 79-year-old man with history of hypertension presented with traumatic subdural hemorrhage, subarachnoid hemorrhage, and epid...
The homeodomain and adjacent CVC domain in the visual system homeobox (VSX) proteins are conserved from nematodes to humans. Humans with missense mutations in these regions of VSX2 have microphthalmia, suggesting both regions are critical for function. To assess this, we generated the corresponding mutations in mouse Vsx2. The homeodomain mutant protein lacked DNA binding activity and the knock...
Heparin-induced thrombocytopenia (HIT) is a transient antibody-mediated hypercoagulability state strongly associated with lower-limb deep-vein thrombosis (DVT). Whether HIT is additionally associated with upper-limb DVT--either with or without central venous catheter (CVC) use--is unknown. We therefore studied 260 patients with antibody-positive HIT to determine the influence of CVC use on freq...
OBJECTIVE To evaluate the effect of bathing patients with 2% chlorhexidine on the rates of central vascular catheter (CVC)-associated bloodstream infection (BSI) at a long-term acute care hospital (LTACH). DESIGN Quasi-experimental study. SETTING A 70-bed LTACH in the greater Chicago area. PATIENTS All consecutive patients admitted to the LTACH during the period from February 2006 to Febr...
BACKGROUND Chest X-ray is routinely performed to check the position of the central venous catheter (CVC) inserted through the internal jugular or subclavian vein, while the further evaluation of CVC malfunction is usually performed by contrast venography. In patients with superior vena cava obstruction, the tip of the catheter is often seen in collateral mediastinal venous pathways, rather than...
Previous work showed that local cooling (LC) attenuates the vasoconstrictor response to whole body cooling (WBC). We tested the extent to which this attenuation was due to the decreased baseline skin blood flow following LC. In eight subjects, skin blood flow was assessed using laser-Doppler flowmetry (LDF). Cutaneous vascular conductance (CVC) was expressed as LDF divided by blood pressure. Su...
BACKGROUND Vascular calcification is a risk factor for the pathogenesis of cardiovascular disease and mortality in dialysis patients. Nevertheless, the association between cardiac valve calcification (CVC) and the outcome of dialysis is still illusive. The purpose of this meta-analysis is to evaluate the association between theCVC and cardiovascular or all-cause mortality in dialysis patients. ...
This study evaluated the incidence of colonization and infection related to Central Vascular Catheters (CVC) in a tertiary care Greek hospital, as well as risk factors associated with catheter-related bloodstream infection (CRBSI). A total of 340 CVCs, were studied in relation to patient clinical and epidemiological data, CVC characteristics, and microbiological culture results. Risk factors we...
BACKGROUND Septic thrombophlebitis increases patient morbidity and mortality following metastatic infections, pulmonary emboli, and/or septic shock. Central venous catheter (CVC) removal for occult septic thrombophlebitis challenges current strategy in neutropenic patients. PATIENTS AND METHODS We prospectively evaluated infection-related mortality in 100 acute leukemia patients, with CVC-rel...
