Minimally Invasive Surgery in Patients With Intracerebral Hemorrhage: A Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: Background: Minimally invasive surgery for intracerebral hemorrhage (ICH) has been evaluated in clinical trials. Although meta-analyses on this topic have been performed in the past, recent trials have added important information to the results of the comparison. However, little work has been done to compare the effect of MIS and conventional treatment on patient prognosis, especially mortality. Methods: PubMed, EMBASE, Web of Science, Ovid, China National Knowledge Infrastructure, and ClinicalTrials.gov were searched on May 1, 2021, for randomized controlled trials of MIS for spontaneous ICH. The primary outcome was defined as death at follow-up, while the secondary outcome was defined as death in different comparisons between MIS and craniotomy (CT) or medication (Me). Results: The initial search yielded 12 high-quality randomized controlled trials involving 2,100 patients. We analyzed the odds ratios (ORs) for MIS compared with conventional treatment, including Me and conventional CT. The OR and confidence intervals (CIs) of the primary and secondary outcomes were 0.62 (0.45-0.85) for MIS vs. conventional treatment. We also conducted subgroup analyses and found that the ORs and CIs for MIS compared with that of conventional treatment in the short-term follow-up were 0.58 (0.42-0.80), and, in the long-term follow-up, was 0.67 (0.46-0.98); and found that ORs were 0.68 (0.48-0.98) for MIS vs. CT and 0.57 (0.41-0.79) for MIS vs. Me. Conclusions: This meta-analysis demonstrates that certain patients with ICH benefit in short- and long-term follow-up from MIS over other treatments, including open surgery and conventional Me.

Project description:Background: The role of tranexamic acid (TXA) in preventing hematoma expansion (HE) in patients with acute spontaneous intracerebral hemorrhage (ICH) remains unclear. We aim to investigate the efficacy and safety of TXA in acute spontaneous ICH with a particular focus on subgroups. Methods: Randomized controlled trials (RCTs) were retrieved from CENTRAL, Clinicaltrials.gov, EMBASE, PubMed, and WHO ICTRP. The primary outcome measurement was HE. The secondary outcome measurements included 3-month poor functional outcome (PFO), 3-month mortality, and major thromboembolic events (MTE). We conducted subgroup analysis according to the CT markers of HE (standard-risk population and high-risk population) and the time from onset to randomization (>4.5 and ≤4.5 h). Results: We identified seven studies (representing five RCTs) involving 2,650 participants. Compared with placebo, TXA may reduce HE on subsequent imaging (odd ratio [OR] 0.825; 95% confidence interval [CI] 0.692-0.984; p = 0.033; I2 = 0%; GRADE: moderate certainty). TXA and placebo arms did not differ in the rates of 3-month PFO, 3-month mortality, and MTE. Subgroup analysis indicated that TXA reduced the risk of HE in the high-risk population with CT markers of HE (OR 0.646; 95% CI 0.503-0.829; p = 0.001; I2 = 0 %) and in patients who were treated within 4.5 h of symptom onset (OR 0.823; 95% CI 0.690-0.980; p = 0.029; I2 = 0%), but this protective effect was not observed in the standard-risk population and patients who were treated over 4.5 h of symptom onset. Conclusions: Tranexamic acid (TXA) may decrease the risk of HE in patients with acute spontaneous ICH. Importantly, the decreased risk was observed in patients who were treatable within 4.5 h and with a high risk of HE, but not in those who were treatable over 4.5 h and in standard-risk population. However, PFO or mortality at 3 months did not significantly differ between patients who received TXA and those who received placebo. TXA is safe for acute spontaneous ICH without increasing MTE.

Project description:Background: Edaravone alleviates neurological deficits among patients with intracerebral hemorrhage; however, its effects on mortality and long-term functional outcomes remain unknown. Objective: To assess clinical outcomes associated with edaravone initiated within 7 days of symptoms onset in intracerebral hemorrhage. Methods: We systematically searched PubMed, Embase, Cochrane Library, CiNii, China National Knowledge Infrastructure, Chinese VIP information, Wanfang Data, and SinoMed for relevant randomized controlled trials from their inception to 1 May 2021 and conducted a comprehensive systematic review and meta-analysis (PROSPERO registration number: CRD42019147801). All-cause mortality and long-term functional outcomes were taken as the primary outcomes. Results: A total of 38 randomized controlled trials including 3,454 participants with acute intracerebral hemorrhage were included. The selected articles were of poor quality. Meta-analysis revealed that edaravone could not reduce all-cause mortality [relative risk (RR) = 0.51; 95% confidence interval (CI) (0.11-2.32); p = 0.38]. No studies reported on long-term functional outcomes in those trials. In addition, edaravone alleviated neurological deficits [mean difference (MD) = -5.44; 95% CI (-6.44 to -4.44); p<0.00001], improved the activities of daily living [MD = 8.44; 95% CI (7.65-9.23); p<0.00001], reduced the hematoma volume [MD = -4.71; 95% CI (-5.86 to -3.56); p<0.00001], and increased treatment response [RR = 1.26; 95% CI (1.22-1.31); p<0.00001]. In terms of safety outcome, there was no significant difference between the edaravone group and the control groups [RR = 1.67; 95% CI (0.92 to 3.06); p = 0.09]. Conclusion: Till date, edaravone does not associate with mortality reduction when initiated within 7 days of intracerebral hemorrhage onset. The effect of edaravone on long-term functional outcomes remains unknown due to lack of data. Although edaravone alleviated neurological deficits, improved activities of daily living, and reduced hematoma volume, we cautiously interpreted the results owing to the overall poor quality and high heterogeneity of the included trials. Presently, the results are insufficient to support edaravone as a routine treatment option for acute intracerebral hemorrhage.
