Carefully remove the needle tip from the fascia.
Gently tighten the purse-string suture around the

Before removing the guide wire, grasp the catheter near
the fascial exit site and carefully slide the needle to the
end of the catheter.
Remove the guide wire and needle from the catheter
simultaneously.

Place a purse-string suture through the lumbo-dorsal
fascia and around the catheter.
The purse-string suture should be placed before
removing the Touhy needle.
The purse-string suture will help the surrounding tissue
fibrose and may reduce the likelihood of CSF leakage,
subcutaneous CSF collection and/or postoperative
headache.
