Difficulty Torqueing Catheter

Next Maneuvers? Try to untorque the catheter, watch pressure Do not try to withdraw the catheter Advance hydrophilic guidewire – soft end and then stiff end. See if the catheter can be easily advanced– if so advance as much as possible. No xs force No success – then what? Inflate BP cuff on upper are > systemic BP and repeat above maneuvers Try to untorque the catheter, watch pressure Do not try to withdraw the catheter Advance hydrophilic guidewire – soft end and then stiff end.

Remove the Catheter

BEFORE REMOVING THE CATHETER Before removing the catheter insert a guidewire Do forearm angiogram with wire in place prior to removing the catheter to insure integrity of the artery Gingerly do POBA and/or insert a long sheath only if necessary Before removing the catheter insert a guidewire Do forearm angiogram with wire in place prior to removing the catheter to insure integrity of the artery Gingerly do POBA and/or insert a long sheath only if necessary

Difficult Case with Severe Tortuosity 80 year old female Long standing HTN Severe PVD with aneurysm Angina Pectoris Excellent radial pulse with normal Allen Test 80 year old female Long standing HTN Severe PVD with aneurysm Angina Pectoris Excellent radial pulse with normal Allen Test

Severe Tortuosity

Alternative Solutions Manipulate with guidewire in catheter Insert long sheath and manipulate with0.035 guidewire Do not just torque but TRANSMIT the torque to the tip! Manipulate with guidewire in catheter Insert long sheath and manipulate with0.035 guidewire Do not just torque but TRANSMIT the torque to the tip!

SUMMARY Complications are easier to avoid than to treat Have the patient take a deep breath You take a deep breath, stay calm and THINK Move the catheter in and out to transmit the torque Use a stiff guidewire if necessary Use a long sheath if necessary Do not keep torqueing if the tip does not move Have the monitor tech MONITOR the pressure Try a blood pressure cuff in the upper arm Use a snare if necessary Complications are easier to avoid than to treat Have the patient take a deep breath You take a deep breath, stay calm and THINK Move the catheter in and out to transmit the torque Use a stiff guidewire if necessary Use a long sheath if necessary Do not keep torqueing if the tip does not move Have the monitor tech MONITOR the pressure Try a blood pressure cuff in the upper arm Use a snare if necessary
