Intracranial hemorrhage is a rare complication of spinal surgery. Case 1 was a 58-year-old man who underwent cervical laminoplasty. No apparent iatrogenic dural rupture or cerebrospinal fluid leakage was observed.

No study so far has attempted to map the 3D topography of brain hypoxia in the individual rat in vivo following middle cerebral artery occlusion (MCAo). In a previous microPET study, we reported that (18)F-fluoromisonidazole ((18)F-MISO) trapping in the brain after MCAo was specific for the hypoxic viable tissue. Here, we used (18)F-MISO microPET to map the 3D topography of brain hypoxia in the acute stage of permanent distal MCAo in individual spontaneously hypertensive rats.

Article Synopsis
  • General anesthesia can affect cerebral circulation, but how it does so is largely unknown.
  • In experiments with rats, the study measured cerebral blood flow and glucose utilization under two different anesthetics: pentobarbital and chloral hydrate.
  • The results showed reduced blood flow with pentobarbital, but increased blood flow with chloral hydrate, indicating a significant difference that could impact how experiment findings relate to normal brain function.

Background: Subcortical ischemic vascular dementia (SVD) caused by small-artery disease is a major cause of dementia. It still remains unclear, however, whether SVD may present with localized regional cerebral blood flow (rCBF) changes. We aimed to clarify the local rCBF changes associated with dementia in patients with early-stage SVD.

Background And Purpose: Nitroimidazole imaging is a promising contender for noninvasive in vivo mapping of brain hypoxia after stroke. However, there is a dearth of knowledge about the behavior of these compounds in the various pathophysiologic situations encountered in ischemic stroke. In this article we report the findings from a systematic review of the literature on the use of the nitroimidazoles to map hypoxia after stroke.
