SUMMARY: This report describes the cases of 2 patients with failed retrieval of an AngioGuard distal protection device after carotid stent placement with rescue retrieval by use of a vertebral catheter. An AngioGuard was deployed before carotid angioplasty and stent placement. Attempted removal of the device with the provided recapture sheath was unsuccessful. A 5F 120-cm vertebral catheter was used to recapture and remove the AngioGuard. This technique is a simple and readily available solution for the retrieval of failed removal of a protection device.
