Medtronic received a report that the pipeline could not be delivered through the marksman, and the distal segment failed to open.
The patient was undergoing surgery for treatment of a saccular, unruptured aneurysm of the right posterior communicating (pcom) artery with a max diameter of 4 mm and a 3 mm neck diameter.
It was noted the patient's vesseltortuosity was severe.
Dual antiplatelet therapy (dapt) was administered: prasugrel.
It was reported that the marksman microcatheter was positioned in sector m1/m2, and an attempt was made to deploy the pipeline.
However, force was exerted, but it was not possible to advance the pipeline.
The stent did not come out of the marksman, and the entire set was removed.
It was also stated the distal segment of the pipeline failed to open.
The stent was not positioned in a bend, less than 50% was deployed, and resheathing was performed less than three times.
A replacement pipeline 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.
Post-procedure angiography showed satisfactory results.
Ancillary devices include a cook 8fr, marksman, avigo guidewire.
