Medtronic received information from literature review that a patient had stroke like symptoms a few hours post pipeline embolization device(ped) treatment for aneurysms at the right internal carotid artery.The mri revealed multiple cortical shower emboli in the right middle cerebral artery.The patient was treated with intravenous heparin for 5 day, and simultaneously started aspirin and clopidogrel.There were no further thrombotic complication.This patient had been on dapt with ticagrelor two days prior to the procedure.It was later noted that some of the pre-procedural dapt had been omitted and delayed due to patient condition.A second patient in the same article reported a patient experienced in stent thrombosis post pipeline embolization device(ped) placement for a right posterior communication artery aneurysm, although the procedure itself was uneventful.It was reported the day after the ped placement procedure, the patient demonstrated left-sided hemiplegia, and mri showed a small capsular infarct on the right posterior limb of the internal capsule.Platelet function studies including collagen¿epinephrine closing time and collagen¿adenosine diphosphate closing time were performed; neither of which was prolonged., despite the patient had been on clopidogrel prior to the procedure.Ticagrelor was started for the patient.Seven days after the ped was placed, an mri showed the patient had occluded internal carotid artery and there was complete in stent thrombosis.Partial recanalization of the stent was achieved, but the frontal branch of the right mca remained persistently occluded.The patient was discharge from the hospital after several days.The above information is extracted from the retrospective study to evaluate the safety and efficacy of ticagrelor in patients undergoing neurovascular procedures.
