Background
Recent clinical trials revealed a substantial clinical benefit for mechanical thrombectomy (MT) in patients with basilar artery occlusion (BAO). While urban areas are sufficiently covered with comprehensive stroke centers and MT expertise, rural areas lack such resources. Structured telemedical stroke networks offer rural hospitals instant consultation by stroke experts, enabling swift administration of intravenous thrombolysis (IVT) on-site and transportation for MT. For BAO patients, data on performance and clinical outcomes in telemedical stroke networks are lacking.
Methods
We retrospectively analyzed data from patients with acute BAO eligible for MT: those treated directly in our comprehensive stroke center (direct-to-center/DC) and those treated in rural hospitals that were telemedically consulted by the Neurovascular Network of Southwest Bavaria (NEVAS) and transferred to our center for MT (drip-and-ship, DS). Key time intervals, stroke management performance and functional outcome after 90 days were compared.
Results
Baseline characteristics, including premorbid status and stroke severity, were comparable. Time from symptom onset to IVT was identical in both groups (118 min). There was a delay of 180 min until recanalization in DS patients, mainly due to patient transport for MT. Procedural treatment time intervals, success of recanalization and complications were comparable. Clinical outcome at 3 months follow-up of DS patients was not inferior to DC patients.
Conclusion
We show for the first time that patients with BAO in rural areas benefit from a structured telemedicine network such as NEVAS, regarding both on-site processing and drip-and-ship for MT. Clinical outcomes are comparable among DS and DC patients.
