Postoperative ischemic changes following brain metastasis resection as measured by diffusion-weighted magnetic resonance imaging.

摘要: Object Brain metastases occur in 10% to 40% of patients harboring cancer. In cases neurosurgical metastasis resection, all postoperative neurological deterioration should be avoided. Reasons for deficits can direct tissue damage due hemorrhage, venous congestive infarcts, or arterial ischemic events leading infarction. The aim this study was evaluate whether infarctions surgery brain and determine their influence on new deficits. Methods Patients who underwent resection had preoperative early (within 48 hours) MRI scans, including diffusion-weighted imaging sequences apparent diffusion coefficient maps, between January 2009 May 2012 were included study. Clinical histopathological data (histopathological results, pre- status, previous tumor-specific therapy) recorded. Results One h...
