Impact of prehospital stroke video triage (PSVT) on thrombolysis and mechanical thrombectomy rates and reduction in neurological disability and length of stay at University Hospital Southampton

Abstract

Introduction: 465 patients underwent PSVT between June 2023 andMay 2025. 32 patients received intravenous thrombolysis and 11 mechanicalthrombectomy. We review the results on reperfusion treatmentMethod: We examined treatment times, length of stay and neurologicaloutcomes in patients treated with thrombolysis and thrombectomy andcompared them with SSNAP data for the same periodResults or details of the case: 32 patients underwent thrombolysis.Door to CT scanning time was halved from 50 min to 26 min. Door toneedle time was 10 minutes faster, reduced from 1:05min to 55min withvideo. Stroke onset time to thrombolysis was 45min quicker, and meanNIHSS 10 pretreatment and 5 post lysis. 20/32 patients were dischargedwithin 48hrs with minimal disability.In the thrombectomy group, door to groin puncture times were faster,pretreatment NIHSS 15 and post 8, with a mean length of stay 4 days andmean 6-month mRS 2.Conclusion: PSVT allows prioritisation of reperfusion cases with fasterthrombolysis and thrombectomy times resulting in a greater reduction inNIHSS and disability with earlier reperfusion treatment, shorter length ofstay and better long-term outcomes. The next challenge is to increaseparamedic and clinician engagement to realise further benefits on patientoutcomes
