Review Meta AnalysisAneurysm rebleeding after placement of external ventricular drainage: a systematic review and meta-analysis.
The association between external ventricular drainage (EVD) and aneurysm rerupture is still a controversial issue. We performed a systematic review and meta-analysis of published series reporting data of EVD placement in aneurysmal subarachnoid hemorrhage (SAH) with the aim to evaluate the relationship between ventricular drainage and aneurysm rebleeding. ⋯ Our study conclusively defined an association between EVD and rebleeding. However, the effective role of EVD in aneurysm rebleeding is insufficiently investigated in the literature. Other significant factors of rebleeding are usually observed in patients requiring ventricular drainage. According to our findings, a causal relationship between EVD and aneurysm rebleeding could be a plausible hypothesis, at least in certain cases.
