Abstract TP303: Real-world Eligibility for Revascularization in Acute Stroke: A 12 Year Single Center Statistics
Aims: Endovascular treatment (EVT) for acute ischemic stroke (AIS) is the new standard of care for well selected, large vessel occlusive strokes.
Hypothesis: We aimed to determine the frequency of patients potentially eligible for IV thrombolysis (IVT) and EVT based on the latest AHA/ASA guidelines.
Methods: Data from a prespecified consecutive AIS registry (ASTRAL, 2003-2014) of a single comprehensive stroke center were examined. All AIS admitted <24hours and sufficient data to determine EVT-eligibility according to AHA/ASA guidelines (class I and IIa recommendations) on IVT and EVT were selected. Another set of more liberal criteria from different EVT trials and clinical practice was also tested. Time windows for EVT-eligibility was 4.5h (allowing for a door-to-groin delay ≤90min) and for IVT 3.5h (door-to-needle delay ≤60min).
Results: A total of 2’704 AIS were included, of whom 26.8% were secondary transferrals. Proportion of IVT-eligible patients was 12.4% for all AIS, and 24.6% and 36.2% for patient arriving <24h and 6h respectively. Frequency of EVT-eligibility differed between the AHA/ASA guideline and the more liberal approach: 2.9% vs. 4.9% of all AIS and 10.5% vs. 17.7% of all patients arriving <6hours. These numbers are in line with the effective number of EVT applied in 2013 (15%) and 2014 (12%).
Conclusions: Of patients arriving within 6h at a comprehensive stroke center, 10.5% are EVT eligible according to AHA/ASA criteria, nearly double (17.7%) with more liberal criteria, and again double for IV thrombolysis (36.2%). These figures may be useful for planning resource needs of stroke care on a regional level.
