It was reported that catheter removal difficulty occurred.The target lesion was located in a severely tortuous circumfex artery.A synergy stent was implanted.An opticross imaging catheter was selected for use.During procedure, after one intravascular ultrasound (ivus) run was performed, a second run was attempted but was not able to acquire an image.The shaft of the catheter began to shake.Ivus was stopped and then the catheter was very difficult to remove from the patient's body.The opticross imaging catheter was able to be removed intact.However, the transducer would not advance or retract within the sheath after removal.Examination was performed under fluoroscopy and detached tip of a non-bsc guidewire was observed in the artery.It was seen under fluoroscopy that the tip of the non-bsc guidewire became entrapped within the implanted synergy stent.No damage was noted on the synergy stent.The patient was stable; however, the patient went to surgery for retrieval of the detached tip.No further patient complications were reported.
