Thrombectomy with or Without Bridging Thrombolysis for Anterior Circulation Stroke.
Neurology India(2023)
Abstract
Background:Currently, there is still no clear consensus on bridging thrombolysis (BT) before mechanical thrombectomy (MT). In this study, we aimed to compare clinical and procedural outcomes and complication rates of BT versus direct mechanical thrombectomy (d-MT) in anterior circulation stroke.Methods:A total of 359 consecutive anterior circulation stroke patients who received d-MT or BT in our tertiary stroke center between January 2018 and December 2020 were retrospectively analyzed. The patients were divided into two groups as Group d-MT (n = 210) and Group BT (n = 149). The primary outcome was the impact of BT on clinical and procedural outcomes, whereas the secondary outcome was the safety of BT.Results:The incidence of atrial fibrillation was higher in the d-MT group (p = 0.010). The median duration of the procedure was significantly higher in Group d-MT than in Group BT (35 vs 27 min, respectively; P = 0.044). The number of patients achieving good and excellent outcomes was significantly higher in Group BT (p = 0.006 and P = 0.03). The edema/malign infarction rate was higher in the d-MT group (p = 0.003). Successful reperfusion, first-pass effects, symptomatic intra-cranial hemorrhage, and mortality rates were similar between the groups (p > 0.05).Conclusions:In this study, BT seems to yield better clinical and procedural outcomes with lower complication rates than d-MT. These findings may support the additional value of intravenous alteplase in anterior system strokes. Further large-scale, prospective, randomized-controlled studies will clarify the gray lines in this consensus, but this paper is important for reflecting the real-world data in developing countries.
