title: Evaluation for hypoperfusion distal to arteriovenous vascular access using skin perfusion pressure in fingers.
abstract: OBJECTIVE
  The usefulness of skin perfusion pressure (SPP) measurement in the assessment of critical ischemia of the lower limb has previously been established. This study investigated whether finger SPP measurement is useful to evaluate hypoperfusion distal to arteriovenous vascular access in dialysis patients.
  
  
  METHODS
  Seventeen asymptomatic hemodialysis patients with upper extremity arteriovenous access and 17 non-dialysis control patients were prospectively examined. SPP in the thumb, the middle finger and the little finger of both hands was measured. The bilateral difference of the mean SPP of the three fingers was evaluated.
  
  
  RESULTS
  The mean difference of SPP between the contralateral and the arteriovenous access sides among hemodialysis patients (33±2 5 mmHg) was significantly larger than the mean difference of SPP between the left and the right hands among control patients (1.0±6.0 mmHg, p<0.01).
  
  
  CONCLUSIONS
  This report shows the potential usefulness of SPP measurement to evaluate hypoperfusion distal to arteriovenous vascular access.
