Comparative Study
Size ratio can highly predict rupture risk in intracranial small (<5 mm) aneurysms.
Management strategies for unruptured intracranial aneurysms (UIAs) are controversial. This study aimed to identify surrogate parameters that highly predict the rupture risk of small (<5 mm) UIAs. ⋯ This study revealed that the size ratio, and not the absolute size, may highly predict the risk of rupture in small UIAs. Size ratio measurements are very simple and provide useful information for determining treatment and follow-up strategies for patients with small UIAs.

Comparison of flow diversion and coiling in large unruptured intracranial saccular aneurysms.
Flow diversion has emerged as an important tool for the management of intracranial aneurysms. The purpose of this study was to compare flow diversion and traditional embolization strategies in terms of safety, efficacy, and clinical outcomes in patients with unruptured, large saccular aneurysms (≥10 mm). ⋯ The PED provides higher aneurysm occlusion rates than coiling, with no additional morbidity and similar clinical outcomes. These findings suggest that the PED might be a preferred treatment option for large unruptured saccular aneurysms.

Hemorrhagic stroke is more common in non-Western settings and does not always share risk factors with other cardiovascular diseases. The association of smoking with hemorrhagic stroke subtypes has not been established. We examined the association of cigarette smoking with hemorrhagic stroke, by subtype (intracerebral hemorrhage and subarachnoid hemorrhage), in a large cohort of older Chinese from Hong Kong. ⋯ Smoking is strongly associated with hemorrhagic stroke mortality, particularly for subarachnoid hemorrhage.
