Direct Thrombectomy versus Bridging Thrombectomy within 6 Hours of Stroke Onset: A Prospective Cohort Study on Cognitive and Physical Function Outcomes.

To evaluate the physical and cognitive functions of patients with stroke who underwent either direct or bridging thrombectomy within 6 hours of stroke onset. Patients with large vessel occlusion in anterior circulation treated with direct (direct group) or bridging thrombectomy (bridging group) were prospectively analyzed between June 2020 and February 2022. The efficacy outcome was the 3-month modified Rankin Scale (mRS) score, the safety outcome was symptomatic intracranial hemorrhage (sICH), and cognitive function was assessed using the Clinical Dementia Rating (CDR) scale at 6 months after stroke. A total of 125 patients (direct group, n = 75; bridging group, n = 50) who had completed follow-up at 3 months by telephone call were included. No significant differences were observed between the direct and bridging groups in terms of an mRS score of 0-2 (25.3% vs 22.0%, respectively; P = .83), an mRS score of 0-3 (37.3% vs 44.0%, respectively; P = .58), sICH (17.3% vs 14.0%, respectively; P = .80), or 3-month all-cause mortality (36.3% vs 30.0%, respectively; P = .34). Sixty-nine patients (direct group, n = 38; bridging group, n = 31) completed the CDR assessment at 6 months after stroke. There was no significant difference in poststroke dementia, defined as a CDR score of ≥1 point between the direct group (42.1%) and bridging group (22.6%) (P = .12). Ordinal regression analyses showed that the CDR score at 6 months was not associated with treatment type (direct thrombectomy vs bridging thrombectomy). With regard to physical and cognitive functions at 3 and 6 months, direct thrombectomy was comparable with bridging thrombectomy in patients who were treated within 6 hours of stroke onset.
