Event Description
Medtronic received a report that the proximal part of the pipeline pushwire became stuck during retraction and the pipeline moved out of position. The patient was undergoing treatment for an unruptured, saccular aneurysm located in the left m1 segment. The max diameter was 2mm, and the neck diameter was 3mm. The patient's vessel tortuosity was moderate. The landing zone was 3mm distal and 3. 25mm proximal.  dual antiplatelet treatment was administered. It was reported that once the device was positioned in the m2 artery, it was deployed by correctly positioning the device in distal m1 and proximal m1 with optimal deployment, covering the neck correctly. When checking the tip and the delivery system it was noted that the device was attached in its area proximal to the delivery system (region of the recapture pad) when making controlled maneuvers to detach it from it to recapture pad with the microcatheter and the delivery system. A sudden proximal shortening of the device was observed, which caused its final location to be below the neck of the aneurysm. Immediately afterwards, the delivery system was removed and another device of the same size was implanted in a distal m1 position, covering the neck without any inconvenience. There was no damage to the catheter or pushwire, and the pushwire had been rotated during removal.  no additional medical/surgical interventions or prolonged hospitalization was required as a result of the event.  the patient did not experience any injury or complications. Angiographic results post procedure showed ineffective coverage of the aneurysm neck with a stent pipeline compacted to the proximal region of the neck of the aneurysm. The devices were prepared according to the instructions for use (ifu). Ancillary devices include a cook shuttlesheath, navien guide catheter, and phenom 27 microcatheter.
