Abstract
Objectives
To examine the clinical outcome of aneurysmal subarachnoid haemorrhage (aSAH) patients exposed to cerebral vasospasm (CVS)-targeted treatments in a meta-analysis and to evaluate the efficacy of intra-arterial (IA) approaches in patients with severe/refractory vasospasm.
Methods
Randomised controlled trials, prospective and retrospective observational studies reporting clinical outcomes of aSAH patients exposed to CVS targeted treatments, published between 2006-2016 were searched using PubMed, EMBASE and the Cochrane Library. The main endpoint was the proportion of unfavourable outcomes, defined as a modified Rankin score of 3–6 at last follow-up.
Results
Sixty-two studies, including 26 randomised controlled trials, were included (8,976 patients). At last follow-up 2,490 of the 8,976 patients had an unfavourable outcome, including death (random-effect weighted-average, 33.7%; 99% confidence interval [CI], 28.1–39.7%; Q value, 806.0; I
2 = 92.7%). The RR of unfavourable outcome was lower in patients treated with Cilostazol (RR = 0.46; 95% CI, 0.25–0.85; P = 0.001; Q value, 1.5; I
2 = 0); and in refractory CVS patients treated by IA intervention (RR = 0.68; 95% CI, 0.57–0.80; P < 0.0001; number needed to treat with IA intervention, 6.2; 95% CI, 4.3–11.2) when compared with the best available medical treatment.
Conclusions
Endovascular treatment may improve the outcome of patients with severe-refractory vasospasm. Further studies are needed to confirm this result.
Key Points
• 33.7% of patients with cerebral Vasospasm following aneurysmal subarachnoid-hemorrhage have an unfavorable outcome.
• Refractory vasospasm patients treated using endovascular interventions have lower relative risk of unfavourable outcome.
• Subarachnoid haemorrhage patients with severe vasospasm may benefit from endovascular interventions.
• The relative risk of unfavourable outcome is lower in patients treated with Cilostazol.
