Which step is essential to ensure safe catheter withdrawal?

• A. Withdraw device rapidly and rely on post-procedure imaging to detect complications.
• B. Confirm catheter/wire are free of entanglements, slowly withdraw under fluoroscopy, maintain sterile technique, monitor for signs of dissection or bleed at access site.
• C. Skip sterile technique to speed up procedure.
• D. Withdraw only if patient reports pain.

Answer: (B)

The essential idea is to perform a controlled, image-guided withdrawal with attention to safety and infection prevention. Before pulling back, you want to confirm that the catheter and any guidewire are free of entanglements or kinks that could cause a snag or vessel injury as tension is released. Then withdraw slowly under real-time fluoroscopy so you can see the catheter’s path, detect any resistance, and immediately notice problems such as dissection, vessel perforation, or unintended movement. Keeping sterile technique throughout the process minimizes infection risk, and monitoring the access site for signs of bleeding, hematoma, or new dissection allows prompt management if a complication starts to develop.

Rushing the withdrawal and relying only on later imaging misses acute issues and can worsen injury. Skipping sterile technique defeats the purpose of minimizing infection. Waiting for the patient to report pain is unsafe because some complications may be silent or present before pain occurs, and patient feedback is not a reliable indicator of safety during catheter manipulation.
