Multicenter StudyTiming of microsurgical resection for ruptured brain arteriovenous malformations: a propensity score-matched analysis using prospective single-center registry data.
The optimal microsurgical timing in ruptured brain arteriovenous malformations (AVMs) is not well understood and is surrounded by controversy. This study aimed to elucidate the impacts of microsurgical resection timing on clinical outcomes. ⋯ Early and delayed resection of ruptured AVMs had similar long-term neurological outcomes. Delayed resection can lead to a higher complete obliteration rate, although the risk of rerupture during the resection waiting period should be vigilantly monitored.

Multicenter Study Observational StudyComputational fluid dynamics for predicting the growth of small unruptured cerebral aneurysms.
Larger cerebral aneurysms are more likely to enlarge, but even small aneurysms can grow. The aim of this study was to investigate the hemodynamic characteristics regarding the growth of small aneurysms using computational fluid dynamics (CFD). ⋯ HSCR may be a useful hemodynamic parameter to predict the growth of small unruptured cerebral aneurysms.
