Medtronic received information through literature review that after technical success with ped placement the lesion remained patent and tended to grow despite placement of 3 peds.There was, however, no re-rupture in this case despite a dual antiplatelet regimen and growth of the lesion.The patient was admitted with h<(>&<)>h grade 4 and a large sah (fisher grade 4).He also developed severe vasospasm, requiring multiple sessions of intra-arterial interventions.The patient never regained consciousness.He was made comfort-care by the family and eventually died 10 days after the initial hemorrhage.This patient presented with an aneurysmal subarachnoid hemorrhage (asah) which was found as a result of a ruptured blister aneurysm (ba) along the dorsum of the right internal carotid artery (ica).The aneurysm was located in the right ica measuring 1.8mm.Mrs at sah was 5.The patient was started on dual antiplatelet therapy prior to placement of the ped.Vct 2 days after admission showed persistent filling of the blister-type aneurysm following placement of 4.5×14 mm pipeline flow diverter.Lateral dsa post admission day 7 showed persistent filling of the blister-type aneurysm and multifocal vasospasm within the left anterior circulation following placement of 2 additional pipeline devices.The vasospasm required multiple sessions of intra-arterial interventions.The three ped 4x14 were placed without complications, however, there was persistent filling after the procedure and the patient died 10 days after the procedure.The patient died as a consequence of the original massive sah and subsequent severe vasospasm.
