Review Case ReportsTime course of recovery following poor-grade SAH: the incidence of delayed improvement and implications for SAH outcome study design.
Data regarding the time course of recovery after poor-grade subarachnoid hemorrhage (SAH) is lacking. Most SAH studies assess outcome at a single time point, often as early as 3 or 6 months following SAH. The authors hypothesized that recovery following poor-grade SAH is a dynamic process and that early outcomes may not always approximate long-term outcomes. To test this hypothesis, they analyzed long-term outcome data from a cohort of patients with poor-grade aneurysmal SAH to determine the incidence and predictors of early and delayed neurological improvement. ⋯ A substantial minority of poor-grade SAH patients will experience delayed recovery beyond the point at which most studies assess outcome. Younger patients, those presenting in better clinical condition, and those without CT evidence of large or eloquent stroke demonstrated the highest capacity for delayed recovery.

Review Case ReportsCerebral microarteriovenous malformations: a series of 28 cases.
Microarteriovenous malformations (micro-AVMs) are a rare subgroup of brain AVMs characterized by a nidus smaller than 1 cm. The authors' purpose in this study was to assess the clinical presentation, radiological features, therapeutic management, and outcome of these lesions. ⋯ Patients with micro-AVMs generally present with large intracranial hemorrhages and neurological deficits. If the initial angiography is negative, then delayed or superselective angiography is recommended. Magnetic resonance imaging may reveal the existence of these lesions. Surgery is the treatment of choice for superficial micro-AVMs, and radiosurgery or embolization can be considered for deep lesions.
