The sublime balloon catheter was used during a lower extremity intervention via right radial access to treat an occluded anterior tibial artery.The physician reported that multiple manipulations of the device were required to attempt to cross the lesion.The guidewire was believed to have kinked proximal to the lesion, within the superficial femoral artery (sfa).Upon withdrawal of the balloon catheter, resistance was encountered at the location of the wire kink.The physician applied gentle traction, at which point the balloon component separated from the catheter shaft and remained inside the vasculature while still attached to the guidewire.A secondary balloon catheter (jade balloon) was subsequently advanced and used to trap and retrieve the separated balloon segment, enabling successful removal of the device from the patient.The procedure was prolonged due to the retrieval process (over an hour), and pedal access was required to complete treatment of the target vessel.There was no reported patient harm or adverse clinical outcome.
