A 65-year old woman presented with acute or chronic renal failure and signs of right heart failure. Renal replacement therapy—using a surgically placed dialysis catheter via the left jugular vein—was repeatedly complicated by altered flows of the dialysis unit, impaired consciousness, new onset of seizures and left-sided hemiparesis. The tip of the dialysis catheter was detected on transesophageal echocardiography within the lumen of the ascending aorta. Further imaging of the neck vessels demonstrated a primary placement of the catheter in the left common carotid artery. This incident underscores the value of ultrasound guidance for placement of intravascular catheters.

Continuous ambulatory peritoneal dialysis technique failure in adult patients treated at a tertiary hospital in central South Africa: a retrospective analytical study.

Background: Continuous ambulatory peritoneal dialysis (CAPD) is one of the kidney replacement therapy (KRT) modalities used in patients with kidney failure. It is the preferred modality in most resource-limited settings as it is more accessible and cost-effective. CAPD technique failure remains a challenge and is associated with an increased risk of morbidity and mortality.

Hemodialysis for chronic kidney disease (CKD) relies on vascular access (VA) devices, such as arteriovenous fistulas (AVF), grafts (AVG), or catheters, to maintain blood flow. Nonetheless, unpredictable progressive vascular stenosis due to neointimal formation or complete occlusion from acute thrombosis remains the primary cause of mature VA failure. Despite emergent surgical intervention efforts, the lack of a reliable early detection tool significantly reduces patient outcomes and survival rates.

High resource settings can circumvent this limitation by resorting to alternative extracorporeal dialysis methods. However, low resource settings (LRS), PD remains the preferred dialysis modality, and the use of off-label catheters for PD results in complications such as omental wrapping and occlusion.

Objective: To determine whether an intensive value-based care educational program that includes a standardized end-stage renal disease (ESRD) transition pathway would improve the number of optimal starts within Kidney Contracting Entities (KCEs).
Study Design: Retrospective cohort study.
Methods: We recorded optimal starts, defined as the initiation of dialysis without a central venous catheter, and the initial modality type (hemodialysis vs peritoneal dialysis [PD]) in adult Medicare patients in a Comprehensive Kidney Care Contracting program.

Introduction: Screening for nasal carriage of Staphylococcus (S.) aureus is associated with a reduction of peritoneal dialysis (PD)-related infections, but conflicting results have questioned the benefit of this practice. This study evaluated the clinical effectiveness of the screening program for nasal carriage of S.
