The rapid fistula declot is an endovascular approach to efficiently salvage the acutely thrombosed dialysis arteriovenous fistula (AVF). Thrombectomy of the AVF has historically been performed in the inpatient setting, but the advent of the outpatient vascular access center has vastly improved the efficiency and cost-effectiveness of dialysis access management. Fistula surveillance has generally been accepted to improve the life span of the AVF; however, due to the contribution of multiple factors, including uremia-induced vascular dysfunction, acute access thrombosis remains an issue. The rapid fistula declot is encapsulated in a simple algorithm of (1) clot removal, (2) repair of culprit stenoses, and (3) flow restoration. The preferred approach to each step is discretionary as long as near-complete evacuation of the fistula and venous outflow pathways of thrombus precedes flow restoration.

In Portugal, as well as in Europe, peritoneal dialysis (PD) use remains low. Reorganization of PD units including a well -structured peritoneal access management protocol are fundamental to improve the take -up of this therapy. We analyzed the procedure and outcomes in a PD unit, addressing two key quality questions: at which level of estimated glomerular filtration rate (eGFR) were patients referred to peritoneal catheter placement and whether if it was timely placed. We retrospectively evaluated all patients submitted to catheter placement between 2017 and June 2020. We analyzed the patient journey from Kidney Replacement Therapies (KRT) Option Appointment, until PD start, as well as demographic and clinical variables, including eGFR at four time points (KRT Options Appointment, PD unit evaluation, catheter placement, and PD start). To explore the adequacy of catheter placement schedule, we compared the characteristics of the patients who started PD within 90 days of catheter placement (Early group), and of those who started after the first 90 days (Late group). We analyzed 48 patients in the Early and 27 in the Late group. The Early group presented a lower eGFR on KRT Options Appointment, with timely intervention: eGFR at catheter placement averaged 8.0 ± 2.1 mL/min/1,72m2. PD start occurred at 7.0 ± 1.9 and 8.0 ± 2.4 mL/min/1.72m2, in the Early and Late group, respectively. None of the patients suffered an urgent transition to HD by CVC. Four patients started PD less than 15 days after catheter placement, all of them without complications. PD patients’ admission involves specific tasks. Administrative tools or indicators to evaluate those processes are lacking. A peritoneal access clinic would allow the formalization of this circuit, allowing a quality and equitable approach to dialysis access. We suggest a structured pathway for peritoneal access management.

Arteriovenous grafts (AVGs) for hemodialysis have a high failure rate, often due to the development of stenosis at the graft-to-vein anastomosis. Angioplasty (PTA) has been used for over two decades to treat AVG stenosis, with good technical success but limited AVG patency. Results of a prospective multi-center randomized trial, comparing stent graft to PTA in AVGs, has demonstrated superior access circuit patency for the stent graft group. Recent publication of this clinical study brings us into an exciting new era of dialysis access management using covered stents to improve durability of catheter-based therapy.

The prevalence rate and the incidence rate of hemodialysis and functioning kidney transplant recipients have continuously increased; on the contrary, those of peritoneal dialysis have continuously decreased since 2006. Dialysis patients have been getting older and have been maintained on dialysis longer. Diabetic nephropathy was the leading cause of end stage renal disease. The type of hemodialysis vascular access has been stable during the last 5 years (arteriovenous fistulas 76%, arteriovenous grafts 16%, central venous catheters 8% at 2016). Peritoneal dialysis catheter was mostly inserted surgically (67%), and swan neck straight tip peritoneal dialysis catheter was the most commonly used (48%). Vascular access was managed by radiologists and surgeons, and the management was fragmented among them in the past. However, since the nephrologists became interested in and knowledgeable about the vascular access, they began to play roles in vascular access management. Vascular access has been mostly created by vascular surgeons (≈60%); tunneled central venous hemodialysis catheter insertion and endovascular intervention such as percutaneous transluminal angioplasty (PTA) and thrombectomy have been mostly performed by radiologists (≈70%). Tunneled hemodialysis catheter insertion and endovascular intervention by nephrologists have slowly but consistently increased. Recently, the number of central venous hemodialysis catheter insertion has decreased, and tunneled hemodialysis catheter has been inserted more than non-tunneled hemodialysis catheter, indicating that vascular access has been created timely and the vascular access team has been educated about and following international guidelines.
