Ticagrelor washout bridged with GPIIb/IIIa inhibitor infusion to facilitate surgical care following placement of pipeline flow diverters: a case report

Abstract

Background: Pipeline flow diverters (PFDs) are becoming increasingly common. Antiplatelet medication is required to minimize periprocedural ischemic events. Short-acting GPIIb/IIIa inhibitors are frequently administered intraprocedurally; however, the role of these agents in postprocedural PFD management in the neurocritical care unit (NCCU) has been overlooked.Case Report: A patient with an unruptured internal carotid artery aneurysm presented for PFD placement. PFD placement was complicated by post-procedure intra-PFD thrombosis and hemispheric ischemia. Aspirin and ticagrelor were restarted, and the surgery department consulted for tracheostomy and percutaneous endoscopic gastrostomy-tube placement. Short-half-life GPIIb/IIIa infusions served as bridges to surgery after aspirin and tirofiban washout.Conclusion: NCCU management of complications of PFD placement remains under-researched. The use of long-acting antiplatelet agents post-PFD limits the safe administration of surgical procedures. Bridging with GPIIb/IIIa infusion may facilitate the safe delivery of intensive care in these cases.
