Acute administration of tirofiban versus aspirin in emergent carotid artery stenting

BackgroundCarotid artery stenting requires antiplatelet therapy for prevention of in-stent thrombosis. Patients suffering from acute ischemic stroke undergoing intravenous thrombolysis and emergent carotid artery stenting (eCAS) are at high risk for intracranial bleeding. We assessed efficacy and safety of acute administration of intravenous tirofiban versus aspirin in these patients.MethodsA retrospective, single center, cohort study was carried out of 32 patients who underwent eCAS (18 received tirofiban, 14 received aspirin) at our comprehensive stroke center (2008–2016).ResultsOf our 32 consecutive eCAS patients, favorable clinical outcomes (modified Rankin scale ≤ 2) were achieved in eight (47%) tirofiban patients and six (46%) aspirin patients (p = 0.96). Overall rates were similar for symptomatic intracranial bleeding (tirofiban 22%, aspirin 29%, p = 0.68) and mortality (tirofiban 18%, aspirin 23%, p = 0.71).ConclusionsTirofiban and aspirin demonstrated similar efficacy and safety in thrombolyzed s...
