RESUMO

INTRODUCCIÓN: Tradicionalmente la indicación del tipo de acceso vascular (AV) se ha basado en la exploración física del cirujano, pero actualmente se sugiere que los métodos de imagen podrían aportar un beneficio. Nuestro objetivo fue valorar si el eco-doppler preoperatorio modifica los resultados del primer AV para hemodiálisis. PACIENTES Y MÉTODOS: Cohorte prospectiva de pacientes sometidos a un primer AV entre junio de 2014 y julio de 2017, a quienes se practicó un eco-doppler preoperatorio (grupo ECO). Se compararon con una cohorte histórica (enero de 2012-mayo de 2014) de primeros AV indicados exclusivamente mediante clínica (grupo CLN). RESULTADOS: Se compararon 86 pacientes del grupo CLN con 92 del ECO, siendo estos últimos más jóvenes (68,4 vs 64,0 años; p = 0,038). Las permeabilidades primarias (CLN/ECO) a 1 y 2 años fueron del 59,5/71,9% y del 53,1/57,8%, marginalmente mejores en el grupo ECO (p = 0,057). Las permeabilidades asistidas a 1 y 2años fueron del 63,2/80,7% y del 58,1/70,2%, siendo significativamente mejores para el grupo ECO (p = 0,010). Requirieron un nuevo AV durante los primeros 6 meses, por falta de permeabilidad/utilidad del inicial, el 26,7% en el grupo CLN y el 7,6% en el ECO (p < 0,001). Se realizaron una media de 1,39 intervenciones para conseguir un AV útil en el grupo CLN y 1,08 en ECO (p = 0,001), siendo el primer AV útil a nivel radiocefálico en el 31,0/45,1% (p = 0,039). CONCLUSIÓN: La indicación del primer AV en función de una exploración mediante eco-doppler preoperatoria podría mejorar de forma significativa la permeabilidad, disminuir la necesidad de nuevos AV y permitir realizarlos más distales


INTRODUCTION: Traditionally, the indication of the type of vascular access (VA) has been based on the surgeon's physical examination, but it is now suggested that imaging methods could provide a clinical benefit. Our aim was to determine whether or not preoperative Doppler ultrasound modifies outcomes of the first VA for haemodialysis. PATIENTS AND METHODS: Prospective cohort of patients undergoing a first VA from June 2014 to July 2017 who had a preoperative Doppler ultrasound (ECO group). They were compared to a historical cohort (January 2012-May 2014) of first VA indicated exclusively by clinical assessment (CLN group). RESULTS: A total of 86 patients from the CLN group were compared to 92 from the ECO group, which was younger (68.4 vs 64.0, P = .038). The primary patency (CLN/ECO) at 1 and 2 years was 59.5%/71.9% and 53.1%/57.8% respectively, marginally better in the ECO group (P = .057). The assisted patency at 1 and 2 years was 63.2%/80.7% and 58.1%/70.2%, respectively, significantly better for the ECO group (P = .010). Due to lack of patency/utility of the initial VA, 26.7% in the CLN group and 7.6% in the ECO group (P <.001) required a new VA during the first 6months. An average of 1.39 interventions were performed to achieve a useful VA in the CLN group and 1.08 in the ECO group (P < .001), the first VA being useful at the radiocephalic level in 31.0%/45.1% (P = .039). CONCLUSION: The indication of the first VA according to a preoperative Doppler ultrasound examination could decrease the need for new VA, enable them to be made more distal, and significantly improve patency

RESUMO

BACKGROUND: This study provides a summary of the 2010 European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry Annual Report (available at www.era-edta-reg.org). METHODS: This report includes data on renal replacement therapy (RRT) using data from the national and regional renal registries in 29 countries in Europe and bordering the Mediterranean Sea. Individual patient data were received from 27 registries, whereas 18 registries contributed data in aggregated form. We present incidence and prevalence of RRT, transplant rates, survival probabilities and expected remaining lifetimes. The latter two are solely based on individual patient records. RESULTS: In 2010, the overall incidence rate of RRT for end-stage renal disease (ESRD) among all registries reporting to the ERA-EDTA Registry was 123 per million population (pmp) (n = 91 798). The highest incidence rate was reported by Turkey (252pmp) and the lowest reported by Montenegro (21 pmp). The overall prevalence of RRT for ESRD at 31 December 2010 among all registries reporting to the ERA-EDTA Registry was 741 pmp (n = 551 005). The prevalence varied from 124 pmp in Ukraine to 1580 pmp in Portugal. The overall number of renal transplantations performed in 2010 among all registries was 29.2 pmp (n = 21 740). The highest overall transplant rate was reported from Spain, Cantabria (73 pmp), whereas the highest transplant rate for living donor kidneys was reported from the Netherlands (28 pmp). For patients who started RRT between 2001 and 2005, the unadjusted 5-year patient survival on RRT was 46.2% [95% confidence interval (CI) 46.0-46.3], and on dialysis 38.6% (95% CI 38.5-38.8). The unadjusted 5-year patient survival after the first renal transplantation performed between 2001 and 2005 was 86.6% (95% CI 86.1-87.1) for deceased donor kidneys and 94.1% (95% CI 93.4-94.8) for living donor kidneys.
