OBJECTIVES: Better identification and triage of acute posterior circulation (PC) stroke patients is needed as the PC ischemic stroke (IS) patients may be allowed longer thrombolysis window than anterior circulation (AC) IS patients and PC patients with hemorrhagic stroke (ICH) may require care in a neurosurgical unit possibly remote from stroke unit. MATERIALS AND METHODS: Consecutive stroke patients treated at a tertiary center with thrombolysis (100% for IS) and/or comprehensive stroke unit care. RESULTS: Altogether, 1641 patients had AC (75%) and 553 PC strokes. The PC-IS patients were younger (65 vs 70), had less often prior hypertension (51 vs 61%), and were twice more often on warfarin. They presented 3.5 times more often with seizure, vomited five times more often, had headache twice as often, and required intubation 2 to 3 times more often despite equal NIHSS (9 vs 8) or GCS (15 both) scores with AC-IS patients. Among PC patients, IS (n = 190) associated with younger age, prior atrial fibrillation (AF) in 25% and dyslipidemia in ~40%. One-third of PC-ICH patients (n = 363) had headache and vomited at the onset. PC-ICH patients had BP median of 177/92 mmHg and blood glucose 7.4 mmol/l on ER arrival. Warfarin use was twice as common in PC-ICH. CONCLUSIONS: Despite being of typical age for multiple cardiovascular conditions the PC-ICH patients less often have a previous history of AF or dyslipidemia than IS patients do. The vomiting PC-ICH patient with hypertensive BP values often has headache and a red flag for hemorrhage is warfarin treatment.
