Hemicraniectomy for Supratentorial Primary Intracerebral Hemorrhage: A Retrospective, Propensity Score Matched Study.

Background And Purpose: Spontaneous supratentorial intracerebral hemorrhage (ICH) contributes disproportionately to stroke mortality, and randomized trials of surgical treatments for ICH have not shown benefit. Decompressive hemicraniectomy (DHC) improves functional outcome in patients with malignant middle cerebral artery ischemic stroke, but data in ICH patients is limited. We hypothesized that DHC would reduce in-hospital mortality and poor functional status (defined as modified Rankin scale ≥5) among survivors at 3 months, without increased complications.

Adult moyamoya disease in an urban center in the United States is associated with a high burden of watershed ischemia.

Background: Adult moyamoya disease is rare in the United States, and patients mostly present with cerebral ischemia. However, clinical and neurodiagnostic correlates of ischemia are not well known in this population. We sought to characterize the clinical and radiographic features of moyamoya disease in a large urban center in the United States, with a focus on angiographic and neuroimaging patterns of ischemia.
