End-stage renal disease is frequently accompanied by cardiac comorbidity that warrants treatment with a cardiovascular implantable electronic device (permanent pacemaker or implantable cardioverter-defibrillator). In the United States, chronic hemodialysis (HD) population, cardiac implantable devices are present in up to 10.5% of patients; a venous HD catheter is utilized for blood access in 18% of prevalent patients. The concomitant presence of a venous HD catheter and cardiovascular implantable device creates a high-risk circumstance, with potential for causing symptomatic central venous stenosis, and for developing complicated endovascular infection...

BACKGROUND: Optimising filter life and performance efficiency in continuous renal replacement therapy has been a focus of considerable recent research. Larger high quality studies have predominantly focussed on optimal anticoagulation however CRRT is complex and filter life is also affected by vascular access, circuit and management factors. We performed a systematic search of the literature to identify and quantify the effect of vascular access, circuit and patient factors that affect filter life and presented the results as a meta-analysis...

INTRODUCTION: Unplanned dialysis start (UPS) associates with worse clinical outcomes, higher utilisation of healthcare resources, lower chances to select dialysis modality and UPS patients typically commenced in-centre haemodialysis (HD) with central venous catheter (CVC). We evaluated patient outcomes and healthcare utilisation depending on initial dialysis access (CVC or PD catheter) and subsequent pathway of UPS patients. METHODS: In this study patient demographics, access procedures, hospitalisations, and major infectious complications were analysed over 12 months in 270 UPS patients...

Sick sinus syndrome (SSS) encompasses a group of disorders whereby the heart is unable to perform its pacemaker function, due to genetic and acquired causes. Tachycardia‑bradycardia syndrome (TBS) is a complication of SSS characterized by alternating tachycardia and bradycardia. Techniques such as genetic screening and molecular diagnostics together with the use of pre-clinical models have elucidated the electrophysiological mechanisms of this condition. Dysfunction of ion channels responsible for initiation or conduction of cardiac action potentials may underlie both bradycardia and tachycardia; bradycardia can also increase the risk of tachycardia, and vice versa...

Gram-positive infections are currently a therapeutic challenge because of the emergence of strains resistant to first-line antibiotics. Consequently, in the last few years, new antibiotics have been developed with activity against multiresistant Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus and strains with intermediate sensitivity to vancomycin. Among the new antibiotics approved for the treatment of these microorganisms, dalbavancin is a semisynthetic lipoglycopeptide derived from teicoplanin, but has a superior efficacy profile to the latter...

During the last decade, the interest of degradable embolics has considerably grown as alternatives for the currently-used permanent embolics: no permanent foreign body, recanalisation for repeat embolization, complete drug delivery in chemoembolization. Their design is not trivial since a lot of requirements need to be satisfied. The degradable embolics should be easily suspended in physiological solutions and contrast media, injectable in catheters with small internal lumen and they have to recover their size and shape after injection, as for any embolic...

Spinal cord injury (SCI) may lead to urinary system disturbances. Patients with SCI usually have neurogenic bladder, and treatment optionss for this condition include clean intermittent catheterization and a permanent indwelling urethral or suprapubic catheter. Complications of catheterization include urinary tract infection, calculi, urinary tract injury, bladder contraction, bladder spasm, renal dysfunction, bladder cancer, and so forth. To the best of our knowledge, ureteral rupture is an unusual complication of catheterization, and ureteral rupture has been rarely reported in SCI patients...

BACKGROUND: -Catheter ablation for ventricular tachycardia (VT) and premature ventricular complexes (PVCs) is common. Catheter ablation of atrial fibrillation is associated with a risk of cerebral emboli attributed to cardioversions and numerous ablation lesions in the low-flow left atrium, but cerebral embolic risk in ventricular ablation has not been evaluated. METHODS: -We enrolled 18 consecutive patients meeting study criteria scheduled for VT or PVC ablation over a 9-month period...

BACKGROUND AND AIM: Refractory ascites has a poor prognosis. Recurrent large-volume paracentesis is the current standard of care; however, it results in circulatory dysfunction and renal dysfunction, and hospitalization is commonly required. Transjugular intrahepatic portosystemic shunt placement is not an option in a substantial number of patients because of contraindications. The placement of a tunneled peritoneal drainage catheter has been shown to be effective in patients with malignant ascites...

The objectives of the present study were to design a method to estimate mammary plasma flow (MPF) in lactating sows using downstream dilution of -aminohippuric acid (AH) and to compare these estimates with MPF estimates based on specific AA as internal markers (MPF-AA). A permanent indwelling catheter was surgically implanted in the femoral artery, and another 2 were inserted in the right cranial mammary vein of 8 second- and third-parity sows on d 76 ± 2 SEM of gestation. On the 3rd and 17th days in milk, arterial and venous blood samples were drawn in hourly intervals from 0...

Semi-permanent dual-lumen tunneled (or tunneled-cuffed) hemodialysis catheters (TDC) are increasingly utilized during renal replacement therapy, while awaiting permanent access maturation or renal recovery. Although there is a wealth of literature focused on placement, infection prevention, and maintenance of catheter patency, circumstances and indications for TDC removal are less well understood. Timely removal of these catheters is an important management decision, with the length of TDC duration representing the largest cumulative risk factor for catheter-associated blood stream infections...

It is difficult to treat large internal carotid aneurysms with simple surgical clipping. Here, we present a retrograde suction decompression (RSD) procedure for large internal carotid aneurysms using a balloon guide catheter combined with a blood-returning circuit and a superficial temporal artery to middle cerebral artery (STA-MCA) bypass.All patients underwent an STA-MCA bypass before the temporary occlusion of the internal carotid artery (ICA). A 6-French sheath was inserted into the common carotid artery (CCA), and a 6-French Patrive balloon catheter was placed into the ICA 5 cm past the bifurcation...

Delivery of a prescribed dialysis dose, which is critical for longevity on hemodialysis, is directly dependent on vascular access (VA). However, VA is fraught with high failure rates and has room for innovation. Arteriovenous fistula (AVF), considered the 'best choice', has a high 'failure to mature' rate. Arteriovenous grafts (AVGs) are considered when patients are poor candidates for or have failed AVF, but have a high incidence of infections and thrombosis. Due to associated morbidity and mortality from complications, central venous catheters are considered only as 'bridging short-term access' when there is an urgent need for dialysis...

BACKGROUND: Conduction disorders requiring permanent pacemaker (PPM) implantation are a known complication of transcatheter aortic valve implantation (TAVI). Indications for permanent pacing in this setting are still controversial. The study aim was to characterize the natural history of conduction disorders related to TAVI, and to identify predictors for long-term pacing dependency. METHODS: Consecutive patients who underwent TAVI were included in this prospective observational study...

Peripherally inserted central catheters (PICCs) have been placed through the peripheral veins, and the best location for the tip of the PICCs is the lower third of the superior vena cava (SVC) and cavo-atrial junction. PICCs are commonly used in intravenous administration, parenteral nutrition therapy, chemotherapy, as well as in critical care units. The success rates in venipuncture are enhanced when ultrasonographic guides are used by the bedside PICC teams. There have been few reports of PICCs placed in super elderly patients with permanent cardiac pacemakers...
