The patient was undergoing a thrombectomy procedure in the left common carotid artery (cca) and the left middle cerebral artery (mca) using a penumbra system red 72 reperfusion catheter (red72), a non-penumbra guide catheter, and a guidewire.During the procedure, while the physician advanced the red72 over the guidewire through the guide catheter for the first pass, the physician noticed under fluoroscopy that the guidewire was not visible even though the physician was pushing forward the guidewire.The physician then decided to remove the red72 from the guide catheter to see the guidewire.While removing the red72, the physician experienced resistance.After removal of the red72, the physician noticed that the distal length of the red72 had fractured in two locations.It was reported that the guidewire had exited through the side of the red72 instead of the distal end of the red72.Therefore, red72 was not used for the remainder of the procedure.The procedure was completed using another aspiration catheter, the same guide catheter, and the same guidewire.There was no report of an adverse effect to the patient.
