Remote Teleproctoring with the TEGUS System for Mechanical Thrombectomy in a Non-Comprehensive Stroke Center: Initial Preliminary Data On Clinical Experience.
Article in Clinical neuroradiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeMechanical thrombectomy (MT) is typically performed by experienced neurointerventional radiologists. However, logistical and geographic limitations often hinder access to rapid MT. This study reports the first clinical experience using TEGUS teleproctoring to support MT conducted by general interventional radiologists (IR) at non-comprehensive stroke centers, compared to on-site proctoring outcomes.
methodsThe Arnau de Vilanova Hospital in Spain 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. Before teleproctoring, the general interventional radiologist underwent six months of neurointerventional training at a primary stroke center. 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.
resultsDuring the study, 49 MTs were performed: 15 with TEGUS teleproctoring and 34 with on-site proctoring. Both groups had similar baseline characteristics, except for NIHSS scores (Tegus 9 [IQR 6-20] vs 18 [IQR 12-22], p = 0.034). No significant differences were found in door-to-revascularization time (82 ± 28.2 vs 84 ± 26.4) min, p = (0.895). The final mTICI distribution and 90-day mRS scores were comparable after adjusting by stroke severity. There were no reports of symptomatic intracranial hemorrhage in either group.
conclusionThis study shows the feasibility of Tegus 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.
