Percutaneous retrieval of a fractured guide catheter using contralateral snaring

Area of Science:

• Interventional Cardiology
• Medical Device Complications

Background:

• Guide catheter kinking and fracture are rare but serious complications during percutaneous coronary intervention (PCI).
• These events can necessitate emergency surgical intervention if percutaneous retrieval is unsuccessful.

Observation:

• A case involving guide catheter kinking and fracture occurred during attempts to engage the left main coronary artery.
• The patient presented with significant iliac artery tortuosity, a potential contributing factor.

Findings:

• A retained guide catheter fragment was successfully retrieved percutaneously.
• A snare device was utilized from the contralateral femoral artery.
• The fractured catheter segment was removed as a "folded-over" piece through the contralateral arteriotomy.

Implications:

• This case demonstrates a successful percutaneous retrieval strategy for fractured guide catheters.
• The technique offers a less invasive alternative to surgical intervention.
• Managing complex anatomy like iliac tortuosity is crucial in preventing and treating such complications.
