Transradial retrieval of unintentionally extracted stent deployed 8 months prior during percutaneous coronary intervention to the stent-jailed side branch


We experienced a case in which a previously deployed stent was extracted during a percutaneous coronary intervention to the stent-jailed side branch by the transradial approach. The stent was dislodged in the radial artery, was fully expanded, and partially deformed, making it difficult to retrieve via the radial sheath. Using a handmade flared guiding catheter, the expanded deformed stent was successfully retrieved via a 6-Fr radial sheath.
