A comparison of cooling techniques to treat cardiac arrest patients with hypothermia.

Introduction. We sought to compare the performance of endovascular cooling to conventional surface cooling after cardiac arrest. Methods.

Natural history of perihematomal edema after intracerebral hemorrhage measured by serial magnetic resonance imaging.

Background And Purpose: knowledge on the natural history and clinical impact of perihematomal edema (PHE) associated with intracerebral hemorrhage is limited. We aimed to define the time course, predictors, and clinical significance of PHE measured by serial magnetic resonance imaging.

Methods: patients with primary supratentorial intracerebral hemorrhage ≥ 5 cm(3) underwent serial MRIs at prespecified intervals during the first month.
