In stroke patients with acute large vessel occlusion, endovascular therapy (EVT) may be performed with or without sedation. Our aim is to describe self-reported intraprocedural comfort in patients undergoing EVT depending on sedation type. We performed a prospective observational single-center study of patients undergoing EVT. Patients were systematically interviewed on the day following intervention using a structured questionnaire addressing five domains (nausea/vomiting, pain of any kind, physical discomfort, emotional discomfort, and medical team interaction). Each domain scored 0 to 2 points for a maximum total of 10 points (a higher score indicating greater discomfort). In addition, satisfaction with procedural comfort was rated on a visual analog scale (VAS), and patients reported whether they would have preferred more, less, or the same amount of sedation. Patients who underwent EVT without sedation (local anesthesia, LA) were compared to those who received procedural sedation (conscious sedation, CS). Seventy-seven questionnaires were completed: 37 (48%) patients underwent EVT with CS while 40 (52%) were treated under LA. Median scores on the self-reported discomfort scale (1[0-2] vs 1[0-2], p = 0.70) and mean scores on VAS (76 ± 25 vs 81 ± 24, p = 0.37) were similar between the CS and the LA group. The proportion of patients who were satisfied with the adopted sedation strategy was similar between groups. EVT without prior sedation seems to be well tolerated. Systematic self-evaluation of patient comfort appears feasible and may become integrated into routine clinical care. Patient-oriented outcomes should be included in future trials of sedation during thrombectomy.
