Computed tomography perfusion (CTP) has been performed to predict which patients with aneurysmal subarachnoid hemorrhage are at risk of developing delayed cerebral ischemia (DCI). Patients with severe arterial narrowing may have significant reduction in perfusion. However, many patients have less severe arterial narrowing. There is a paucity of literature evaluating perfusion changes which occur with mild to moderate narrowing. The purpose of our study was to investigate serial whole-brain CTP/computed tomography angiography in aneurysm-related subarachnoid hemorrhage (aSAH) patients with mild to moderate angiographic narrowing. ⋯ Our preliminary study demonstrates there is a correlation between mild to moderate angiographic narrowing and serial changes in perfusion in patients with aSAH. Patients developing DCI tended to have progressively worsening CBF compared with those not developing DCI.

Medical student interest in neurosurgery is decreasing and resident attrition is trending upwards in favor of more lifestyle-friendly specialties that receive greater exposure during medical school. The University of Toronto began offering an annual two week comprehensive, focused surgical experience (Surgical Exploration and Discovery (SEAD) program) to 20 first year medical students increasing exposure to surgical careers. This study determines how SEAD affects students' views of a career in neurosurgery. ⋯ This surgical exposure intervention increased understanding about neurosurgery and reduced overall interest in neurosurgery as a career. However, those remaining interested were motivated to plan further neurosurgical clinical experiences. The SEAD program may, therefore, aid in early selection of students motivated to satisfy the demands of a neurosurgical career.
