- Background Two randomized trials have evaluated clipping and coiling in patients with ruptured aneurysms. Aggregated evidence for management of ruptured and unruptured aneurysms is missing. Objective To conduct a meta- analysis evaluating clinical outcome after aneurysm treatment. Methods PubMed, Cochrane Central Register of Controlled Trials, and Clinicaltrials. gov were searched for studies evaluating aneurysm treatment. The primary outcome measure was an independent clinical outcome ( modified Rankin scale 0- 2, Glasgow Outcome Scale 4- 5, or equivalent). Secondary outcomes were poor outcome and mortality. ORs were calculated on an intention- to- treat basis with 95% Cls. Outcome heterogeneity was evaluated with Cochrane's Q test ( significance level cut- off value at < 0.10) and l(2) ( significance cut- off value > 50%) with the Mantel-Haenszel method for dichotomous outcomes. A p value < 0.05 was regarded as statistically significant. Results Searches yielded 18 802 articles. All titles were assessed, 403 abstracts were evaluated, and 183 full-text articles were read. One- hundred and fifty articles were qualitatively assessed and 85 articles were included in the meta- analysis. Patients treated with coiling ( randomized controlled trials ( RCTs)) had higher independent outcome at short- term follow- up ( OR= 0.67, 95% Cl 0.57 to 0.79). Independent outcome was favored for coiling at intermediate and long- term follow-up ( RCTs and observational studies combined-OR= 0.80, 0.68 to 0.94 and OR= 0.81, 0.71 to 0.93, respectively). Independent outcome and lower mortality was favored after coiling in unruptured aneurysms ( database registry studies) at short- term follow- up ( OR= 0.34, 0.29 to 0.41 and OR= 1.74, 1.52 to 1.98, respectively). Conclusions This meta- analysis evaluating clinical outcome after coiling or clipping for intracranial aneurysms, indicates a higher independent outcome and lower mortality after coiling.

- BACKGROUND AND PURPOSE: Intravenous thrombolysis with tissue plasminogen activator is standard treatment in acute stroke today. The benefit of endovascular treatment has been questioned. Recently, studies evaluating endovascular treatment and intravenous thrombolysis compared with intravenous thrombolysis alone, have reported improved outcome for the intervention group. The aim of this study was to perform a meta-analysis of randomized controlled trials comparing endovascular treatment in addition to intravenous thrombolysis with intravenous thrombolysis alone.METHODS: Databases were searched for eligible randomized controlled trials. The primary outcome was a functional neurological outcome after 90 days. A secondary outcome was severe disability and death. Data were pooled in the control and intervention groups, and OR was calculated on an intention to treat basis with 95% CIs. Outcome heterogeneity was evaluated with Cochrane's Q test (significance level cut-off value at <0.10) and I(2) (significance cut-off value >50%) with the Mantel-Haenszel method for dichotomous outcomes. A p value <0.05 was regarded as statistically significant.RESULTS: Six studies met the eligibility criteria, and data from 1569 patients were analyzed. A higher probability of a functional neurological outcome after 90 days was found for the intervention group (OR 2, 95% CI 2 to 3). There was a significantly higher probability of death and severe disability in the control group compared with the intervention group.CONCLUSIONS: Endovascular treatment in addition to intravenous thrombolysis for acute ischemic stroke leads to an improved clinical outcome after 3 months, compared with patients receiving intravenous thrombolysis alone.
