Medtronic received a report that the pipeline pushwire came loose from the device.
The patient was undergoing surgery for treatment of a saccular, previously ruptured aneurysm of the right posterior communicating (pcom) artery with a max diameter of 4.
5 mm and a 4 mm neck diameter.
It was noted the patient's vessel tortuosity was minimal.
Dual antiplatelet therapy (dapt) was administered, and the platelet reactivity units (pru) level was 126.
It was reported that the pipeline was advanced through the phenom microcatheter which was distal in the m2 region.
The pipeline was then unsheathed in the m1 region and slowly dragged back to the terminus landing zone.
During the drag process, the distal end of the pipeline opened.
The physician wanted to advance the pipeline distally since they pulled the pipeline down too proximal.
The phenom was advanced with a slight pull on the pushwire to recapture the pipeline.
Under fluoro, it was noticed the pushwire had no friction and came loose from the device.
Since the pipeline had only been deployed about 2-3 mm, the pipeline and microcatheter were removed.
There was no vessel injury, and another device was used to complete the procedure.
It was indicated that all devices were prepared as per the instructions for use (ifu), and no patient symptoms or further complications were reported as a result of this event.
Ancillary devices include a 9f terumo pinnacle, ballaste 90cm 6f, 072 navien, headway duo 156cm, phenom 27 150cm, syncro2 soft, target xl 5x10 360.
