title: Preoperative physical examination for primary vascular access--reliability in determining vessel quality.
abstract: OBJECTIVE
  The purpose of this prospective clinical study was to evaluate the reliability and adequacy of preoperative physical examination in determining the quality of vessels prior to primary vascular access procedure by performing peroperative completion fistulography.
  
  
  METHODS
  26 consecutive patients who were scheduled for primary vascular access surgery, between July 2001 and June 2002, were included. Findings between the preoperative physical examination and peroperative completion fistulography were compared.
  
  
  RESULTS
  Of the 26 patients that were initially enrolled in the study, 4 patients were excluded because physical examination showed poor superficial arm veins and 2 patients had not undergone access procedure by the end of the study. The remaining twenty patients constituted the actual study group. The arteriovenous fistula could be performed at the chosen level and way in all 20 patients. The findings between preoperative physical examination and peroperative fistulography were compatible and the specificity of physical examination to detect patent inflow and outflow vessels was 100%. Due to the fact that 4 patients in whom a poor vein was suspected were excluded, the sensitivity could not be assessed.
  
  
  CONCLUSIONS
  Preoperative physical examination seems to be reliable and adequate method in determining vessel quality prior primary vascular access surgery. According to our study, its specificity is high in determining patent inflow and out-flow vessels. However, because of exclusion of patients with suspected problem, sensitivity cannot be determined.
