O01 Remote teleproctoring with the TEGUS system for mechanical thrombectomy in a non-comprehensive stroke center: initial preliminary data on clinical experience

<h3>Introduction</h3> Mechanical thrombectomy (MT) is typically performed by experienced neurointerventional radiologists. However, logistical and geographic limitations often hinder access to rapid MT, especially in remote areas. <h3>Aim of Study</h3> To explore the use of remote teleproctoring to support MT conducted by general interventional radiologists (IR) at thrombectomy capable centers, compared to on-site proctoring outcomes. <h3>Methods</h3> The Arnau de Vilanova Hospital in Spain, serving 500,000 people over 12,000 km², used to transfer stroke patients requiring MT to a comprehensive stroke center 160 km away. To overcome COVID-19 mobility restrictions, the Tegus Teleproctoring System was installed. From April 2021 to May 2023, general IR conducted MT either with on-site proctor supervision or teleproctoring support. We aim to compare clinical outcome of patients receiving MT according to proctoring method <h3>Results</h3> During the study, 51 MTs were performed: 17 with TEGUS teleproctoring and 34 with on-site proctoring. Both groups had similar baseline characteristics, except for NIHSS scores (Tegus 9 (IQR 6-20) v/s 18 (IQR 12-22), p: 0,034). No significant differences were found in door-to-revascularization time (82 (SD 28.2) v/s 84 (SD 26.4) min, p: 0.895). The final mTICI distribution and 90-day mRS scores were comparable. There were no reports of symptomatic intracranial hemorrhage in either group. <h3>Conclusion</h3> This study shows the feasibility of remote teleproctoring during emergent cases of MT in a remote hospital. It could improve the learning curve of interventional radiologists with limited experience in MT, and lower the territorial inequity associated to MT. <h3>Disclosure of Interest</h3> no.
