Utilidad Del Mapeo Ecográfico Preoperatorio Para Los Accesos Vasculares De Hemodiálisis

Objectives: To assess the clinical usefulness of routine doppler ultrasound vascular mapping of upper extremities before creating a vascular access (VA) for haemodialysis.Material and methods: A retrospective single-centre study conducted over a four-year period including end-stage renal disease (ESRD) patients referred to for VA creation for haemodialysis. Patients with previous VA in the same upper extremities were excluded. Two study groups were formed: Physical examination (PE: June 2011-February 2014) and ultrasound mapping (US: March 2014-June 2015). An analysis was performed on the demographic variables, comorbidities and AV location. The results of the patency rates of the radio-cephalic fistulae (RCF) subgroup were recorded, immediately (48 h), early (4 weeks), and late (6 months).Results: The study included a total 81 patients (42 PE, 39 US), with 63% males. The mean age was 66.5 +/- 13.1 years, and 81% were affected on the left side. There were no significant differences between the groups as regards, demographics, comorbidities, or ESRD aetiology. The VA type (PE vs. US): 47.6 vs. 69.2% radio-cephalic fistula* (*P<.05), 38.1 vs. 10.3% brachial-cephalic fistula*, vs. US): 47.6 vs. 69.2% radio-cephalic fistula* (*P<.05), 38.1 vs. 10.3% brachial-cephalic fistula',, 11.9 vs. 17.9% brachiobasilic fistula, and 2.4 vs. 2.6% humeral-axillary grafts. RCF patency rates: Immediate 90 vs. 85.2%, early 75 vs. 100%*, and late 88.9 vs. 55%*; respectively. However, an increase in AV performed in other territories was observed in PE group (25 vs. 3.7%*) in RCF.Conclusions: Routine doppler ultrasound mapping of upper extremities before VA creation in our centre allowed the distal vascular territory to be optimised, and improved the primary patency rates of both early and late radio-cephalic fistulas.
