Abstract: (1) Background: Whether anticoagulation can be resumed in atrial fibrillation (AF) combined with intracranial hemorrhage (ICH), and which anticoagulation modality is used with better efficacy and safety, is unknown. (2) Method: Randomized controlled trials (RCTs) and observational studies on relevant topics were included by searching five databases: PubMed, EMBASE, EBSCO, Cochrane Central Register of Controlled Trial and ClinicalTrials. Bayesian network meta-analysis was performed to analyze the effect of oral anticoagulant (OAC), new oral anticoagulant (NOAC), warfarin, antiplatelet, left atrial appendage occlusion (LAAO) and no therapy in patients with AF after intracranial hemorrhage. (3) Results: We included 16 studies involving 25,483 patients. Compared with no antithrombotic therapy, the risk of thromboembolism and all-cause mortality were both reduced with OAC (OR: 0.38, 95% CI: 0.21-0.67; OR: 0.45, 95% CI: 0.25-0.8) and LAAO (OR: 0.11, 95% CI: 0.01-0.76; OR: 0.11, 95% CI: 0.01-0.88), and there was no increased risk of recurrent intracranial hemorrhage. Regarding thromboembolism, OAC (OR: 0.28, 95% CI: 0.11-0.69) was superior to antiplatelet therapy, and antiplatelet therapy (OR: 12.59, 95% CI: 1.57-133.50) was associated with a higher risk of thromboembolism than LAAO. There were no significant differences in recurrent intracranial hemorrhage between the interventions. LAAO appeared to be the best option for reducing thromboembolism (SUCRA: 0.96), recurrent intracranial hemorrhage (SUCRA: 0.75) and all-cause mortality (SUCRA: 0.94). (4) Conclusions: Based on this network meta-analysis, we hypothesize that LAAO has the highest likelihood of reducing the risk of thromboembolism and recurrent intracranial hemorrhage, as well as all-cause mortality in patients with AF after intracranial hemorrhage, followed by OAC.
