Which vascular access for chronic hemodialysis in uremic elderly patients?
The type of hemodialysis vascular access (fistula, graft, catheter) employed plays an important role in the results of dialysis treatment. Moreover, different complications can affect the vascular access and interfere with the morbidity and mortality of patients. The ideal vascular access is the Cimino Brescia fistula. Graft and catheter methods should be considered as 'second choice' because they present a higher incidence of complications, mainly due to thrombosis and infections. Finally, in elderly patients the vascular bed is frequently damaged and this may make it difficult to create a Cimino Brescia fistula. In a 5-year period, 140 elderly patients (>65 years) and 63 'young' patients (< 65 years) started dialysis treatment in our facility. In the elderly group, a native fistula was created in 88% of cases, whereas in the younger patients the percentage was 94% (p: NS). The grafts were, respectively, 11% in elderly and 6% in young patients. Only in one case, in one elderly patient, was a permanent catheter the first vascular access. We also report survival rate of the first vascular access, the incidence of thrombosis, and the need for creating another type of access. We suggest that a native fistula can be easily created in elderly patients and a 'second choice' access should be limited to a small proportion of patients.
