title: A comparison of a 'J' wire and a straight wire in successful antegrade cannulation of the superficial femoral artery.
abstract: OBJECTIVE
  To evaluate the success of two different types of wire in common use in their ability to successfully cannulate the superficial femoral artery (SFA) using antegrade puncture.
  
  
  METHODS
  50 consecutive patients in whom antegrade infra-inguinal intervention was planned, underwent common femoral arterial puncture and then cannulation with either a standard 3mm 'J' wire or a floppy tipped straight wire (William Cook-Europe). The frequency with which each type of wire entered the SFA or profunda femoris artery without image guidance was recorded. Further analysis was also made of the success of manipulation of the wire into the SFA following profunda cannulation and the use of alternative guide wires.
  
  
  RESULTS
  In 19 out of 25 (76%) patients the 'J' wire correctly entered the SFA without image guidance. Only 5 out of 25 (25%) of straight wires entered the SFA with the initial pass (p < 0.0001). Following further manipulation with the same wire all except 1 'J' wire was successfully negotiated into the SFA. The same was true for only 9 of the remaining straight wires with 11 patients requiring an alternative guide wire.
  
  
  CONCLUSIONS
  When performing antegrade cannulation of the SFA a 'J' wire is more likely to be successful than a straight guide wire.
