Insights
Retrieving disrupted devices during percutaneous coronary intervention and endovascular treatment is challenging. A novel "flower technique" using a modified guiding catheter safely resolves device entrapment without additional cost or experience.
Area of Science:
- Cardiovascular Interventions
- Medical Device Technology
Background:
- Percutaneous coronary intervention (PCI) and endovascular treatment (EVT) are common procedures.
- Device retrieval complications can occur during these interventions, posing significant challenges.
Abstract:
We report two case series in which we encountered the difficulties to retrieve disrupted devices during percutaneous coronary intervention and endovascular treatment. The broken devices were successfully and safely retrieved by the "flower technique" that creates multiple cut and slit in the tip of the guiding catheter. This technique can be easily and safely applied in situations where a balloon catheter or stent has been disrupted and device entrapment has occurred, as the technique simply involves manually placing multiple cuts or slits in the tip of the guiding catheter. Transcatheter interventionists should be familiar with this technique because it can be bailout from device entrapment without additional cost or clinical experience.
