However, studies analyzing the influence of the type of vascular access on the survival of very elderly patients (≥75 years) initiating HD are few and involve only a limited number of patients. We studied a cohort of 5,466 incident patients who started HD; of these, 1,841 were aged ≥75. Types of vascular access for HD were classified as either CVC, which included both tunneled and non-tunneled catheters, or AV, which included AV fistula and grafts. The outcome of the study was all-cause mortality during the follow-up period. In the whole cohort, AV use was associated with a survival advantage over CVC use (88 and 63% at 2 and 5 years, respectively, in patients with an AV as compared to 75 and 48% in patients with a CVC) (p < 0.0001). Among patients ≥75, CVC use was associated with a higher number of deaths compared to AV use. Patients ≥75 with an AV showed a greater survival as compared to patients ≥75 with a CVC (80 and 53% at 2 and 5 years, respectively, vs. 68 and 43%; p < 0.0001). Multivariate analysis revealed that CVC use and the presence of arrhythmia were independent risk factors of death in patients ≥75, whereas obesity was associated with greater survival. In conclusion, the type of vascular access has a significant influence on the survival of very elderly patients (≥75) initiating HD. CVC use was associated with poorer survival compared to AV access.Tipo de ítem | Ubicación actual | Signatura | Estado | Fecha de vencimiento |
