Intracardiac vascular access in haemodialysis: A last resort for exhausted traditional access.

Depletion of veins for dialysis access is a challenging life threatening situation for patients in need of haemodialysis. The utilisation of intracardiac catheter is a rare procedure with scarce reported experience. We describe the case of a 68-year-old male that contributes to the limited knowledge of performing a life-saving intracardiac catheter placement for emergency haemodialysis in a patient without immediate alternative renal replacement therapy available. We also retrospectively analyse the experience reported so far and summarise complications and outcomes. In our case, the patient was able to pursue haemodialysis after intracardiac catheter placement without any complications. Two weeks later, the patient successfully received a kidney transplant from a deceased donor and has a serum creatinine of 1.7 mg/dL after 2 years of follow-up. There are only four reported cases of kidney transplantation after the procedure, including our own. Intracardiac catheter is an emerging option that could be considered in certain patients as the last resort. Further investigation with regards to patient candidacy and procedure security are necessary.

Percutaneous Left Atrial Appendage Closure in Patients with Non-Valvular Atrial Fibrillation and End-Stage Renal Disease on Hemodialysis: A Case Series.

Non-valvular atrial fibrillation (NVAF) is the most common cardiac arrhythmia in the general population, and its prevalence increases among patients with chronic kidney disease (CKD) undergoing hemodialysis. This population presents high risk of both hemorrhagic and thrombotic events, with little evidence regarding the use of oral anticoagulation treatment (OAT) and multiple complications arising from it; however, stroke prevention with percutaneous left atrial appendage closure (LAAC) is an alternative to be considered. We retrospectively describe the safety and efficacy of percutaneous LAAC in eight patients with NVAF and CKD on hemodialysis during a 12-month follow-up. The mean age was 78.8 years (range 64-86; SD ± 6.7), and seven patients were male. The mean CHA2DS2-VASC and HAS-BLED scores were high, 4.8 (SD ± 1.5) and 3.8 (SD ± 1.3), respectively. Seventy-five percent of the patients were referred for this intervention due to a history of major bleeding, with gastrointestinal bleeding being the most common type, while the remaining twenty-five percent of the patients were referred because of a high risk of bleeding. The percutaneous LAAC procedure was successfully completed in 100% of the patients, with complete exclusion of the appendage without complications or leaks exceeding 5 mm. There was one death not related to the procedure four days after the intervention. Among the other seven patients, no deaths, cardioembolic events or major bleeding were reported during the follow-up period. In our sample, percutaneous LAAC appears to be a safe and effective alternative to anticoagulation in patients with NVAF and CKD on hemodialysis.

Documento de consenso para la formación en ecografía en la especialidad de Nefrología / Consensus document for ultrasound training in the specialty of Nephrology

La ecografía es una herramienta esencial en el manejo del paciente nefrológico que permite el diagnóstico, el seguimiento y la realización de intervencionismo sobre el riñón. La utilidad de los ultrasonidos en Nefrología no se circunscribe exclusivamente al estudio ecográfico del riñón. Mediante ecografía el nefrólogo puede, además, optimizar el manejo de la fístula arteriovenosa para hemodiálisis, medir el riesgo cardiovascular (grosor íntima-media), implantar catéteres centrales para hemodiálisis ecoguiados y ayudar en la colocación de los peritoneales, así como calcular la volemia del paciente mediante ecografía cardiaca básica, ecografía de la vena cava inferior y pulmonar. Desde el Grupo de Trabajo en Nefrología Diagnóstica e Intervencionista (GNDI) de la Sociedad Española de Nefrología (SEN) hemos elaborado este documento de consenso en el que se resumen las principales aplicaciones de la ecografía en Nefrología, incluyendo los requisitos técnicos básicos necesarios, el marco normativo y el nivel de capacitación de los nefrólogos en esta materia. El objetivo de este trabajo es promover la inclusión de la ecografía, tanto diagnóstica como intervencionista, en la práctica clínica habitual del nefrólogo y en la cartera de servicios de Nefrología con la finalidad de ofrecer un manejo diligente, eficiente e integral al paciente nefrológico

Ultrasound is an essential tool in the management of the nephrological patient allowing the diagnosis, monitoring and performance of kidney intervention. However, the usefulness of ultrasound in the hands of the nephrologist is not limited exclusively to the ultrasound study of the kidney. By ultrasound, the nephrologist can also optimize the management of arteriovenous fistula for hemodialysis, measure cardiovascular risk (mean intimate thickness), implant central catheters for ultrasound-guided HD, as well as the patient's volemia using basic cardiac ultrasound, ultrasound of the cava inferior vein and lungs. From the Working Group on Interventional Nephrology (GNDI) of the Spanish Society of Nephrology (SEN) we have prepared this consensus document that summarizes the main applications of ultrasound to Nephrology, including the necessary basic technical requirements, the framework normative and the level of training of nephrologists in this area. The objective of this work is to promote the inclusion of ultrasound, both diagnostic and interventional, in the usual clinical practice of the nephrologist and in the Nephrology Services portfolio with the final objective of offering diligent, efficient and comprehensive management to the nephrological patient
