Clinical outcomes of methamphetamine users with aneurysmal subarachnoid hemorrhage (aSAH) are unknown. ⋯ Methamphetamine users have significantly worse outcomes at 1 and 3 years following aSAH. Further analysis is necessary to understand the pathological response associated with methamphetamine use in this setting.

Leukoaraiosis (LA) is defined as ischemic white matter lesions associated with increased stroke risk and poor post-stroke outcomes. These lesions are likely the result of diffuse angiopathic changes affecting the cerebral small vessels. We investigated whether pre-existing LA burden is associated with outcomes in patients with large cerebral artery occlusion undergoing intra-arterial therapy (IAT) for acute ischemic stroke (AIS). ⋯ Severity of LA is linked to poor collateral grade in AIS patients undergoing IAT for PAO; however, greater LAv appears not to be a contraindication for acute intervention.

A 65-year-old man with a left cavernous internal carotid artery cerebral aneurysm experienced a premature detachment of the first framing coil (10 mm × 40 cm Penumbra Complex Standard) during a coil embolization procedure. The coil herniated into the anterior cerebral artery and pericallosal artery. ⋯ A Trevo ProVue retrievable stent was then used to retrieve the coil without any adverse events. This case report highlights a novel use of a stent for the removal of a foreign body from the cerebrovascular system.
