Operative exploration revealed anterior communicating aneurysms in these patients. It is thought possible that these patients harbored aneurysms which failed to exhibit on angiograms due to temporary thrombosis or development of abnormal cerebral vessels. CT scanning was important for diagnosis of these patients.展开更多

Since there has been dispute about the risks of gastrointestinal bleeding （GIB） and intracranial hemorrhage （ICH）, we sought to conduct a systematic review and network meta-analysis using Bayesian inference to analyze the risks of GIB and ICH in AF patients taking NOACs. Methods： We analyzed data from 20 randomized controlled trials of 91 671 AF patients receiving anticoagulants, antiplatelet drugs, or placebo. Bayesian network meta-analysis of two different evidence networks was performed using a binomial likelihood model, based on a network in which different agents （and doses） were treated as separate nodes. Odds ratios （ORs） and 95% confidence intervals （CIs） were modeled using Markov chain Monte Carlo methods Results： Indirect comparisons with the Bayesian model confirmed that aspirin＋clopidogrel significantly increased the risk of GIB in AF patients compared to the placebo （OR 0.33, 95% CI 0.01-0.92）. Warfarin was identified as greatly increasing the risk of ICH compared to edoxaban 30 mg （OR 3.42, 95% CI 1.22-7.24） and dabigatran 110 mg （OR 3.56, 95% CI 1.10-8.45）. We further ranked the NOACs for the lowest risk of GIB （apixaban 5 mg） and ICH （apixaban 5 mg, dabigatran 110 mg, and edoxaban 30 mg）. Conclusions： Bayesian network meta-analysis of treatment of nonvalvular AF patients with anticoagulants suggested that NOACs do not increase risks of GIB and/or ICH, compared to each other.展开更多
