摘要
Introduction
The safety and feasibility of intravenous cangrelor use for neuroendovascular procedures needs to be investigated.Aim of Study
To investigate safety and feasibility of intravenous dose-adjusted cangrelor in patients undergoing neuroendovascular proceduresMethods
We conducted a retrospective study on patients who underwent neuroendovascular procedures and were placed on intravenous cangrelor. Cangrelor was administered as a 15 mcg/kg bolus followed by 2 mcg/kg/min infusion titrated to goal P2Y12 reaction unit (PRU) level of 50 to 150, then transitioned to oral antiplatelet therapy.Results
A total of 67 patients were included (mean age (years): 57.8 ± 18.5, males: 34 (50.7%), Black: 51 (76.1%)). The most common comorbidity was hypertension (n=38/66, 56.7%). Six patients (9.0%) received intravenous thrombolysis. Cangrelor infusion was used for stent placement (n=21, 32.3%). Stenting occurred intracranially in 18 patients, extracranially in 22 patients, and both intracranial and carotid arteries in 3 patients. PRU levels were measured in 61 patients (91.0%). Approximately 40.9% of the patients had favorable outcomes with modified Rankin Scale (mRS) score of 0 to 2 at 90 days (n=18/44). Within 1-year, 4 patients had recurrent/new strokes (7.7%), 2 with symptomatic intracranial hemorrhage [sICH] (3.0%), 3 with asymptomatic intracranial hemorrhage [aICH] (4.5%), and 1 gastrointestinal bleeding event were recorded (1.5%). When stratified by supratherapeutic PRU level (PRU < 50), there was a difference in sICH (p=0.044) but not aICH (p=0.203).Conclusion
This is the first report to demonstrate the safety and effectiveness of intravenous cangrelor use titrated by platelet function testing in neuroendovascular procedures.Disclosure of Interest
