Medtronic (covidien) received information that during a flow diversion treatment of a left large saccular unruptured carotid cavernous aneurysm, the physician reported that the pipeline was deployed but the proximal portion of the ped curled into the aneurysm.It was reported that the pipeline was implanted at the targeted location with no friction during delivery.The physician attempted to perform angioplasty to expand/appose to vessel wall.While attempting angioplasty the proximal end of the pipeline foreshortened into the aneurysm.The physician attempted to correct the issue via few maneuvers using alligator retrieval device, balloons, wire and guide catheter, however, these maneuvers were unsuccessful.Therefore, the proximal portion of the ped is within the aneurysm.The patient died 9 days post procedure from left hemisphere stroke.
