RESUMO
For almost twenty years the Institute of General Surgery and Organ Transplant at Palermo Polyclinic has dealt with vascular problems arising during the preparation, monitoring and search for vascular access in uremic patients. For a number of years advantage has been taken of the vascular status in uremic patients; in fact, the possibility of creating a long-lasting and efficient vascular access also depends on the optimal use of the patient's vascular resources. The authors briefly describe the clinical and instrumental diagnostic strategy for the approach to a vascular access in uremic patients which must be correct and must respect the vascular resources of a "chronic" patient by definition, for whom hemodialysis is often the only prospect of therapy.
