Increased cerebral lactate levels are a well-known aspect of the sequelae of the metabolic derangements that follow cerebral ischemia. A new technique has recently become available to sample cerebral venous blood from the superior sagittal sinus on a long-term basis in conscious rats. We report the applicability of this method to assess serial biochemical responses to brain injury. Serum sample...

Letters to the Editor will be published, if suitable, as space permits. They should not exceed 1,000 words (typed double-spaced) in length and may be subject to editing or abridgment. To the Editor. Noninfectious thrombosis of cerebral veins is commonly found in patients with hereditary coagulation or immunologic disorders and during pregnancy or intake of contraceptive drugs.

a 20-year-old woman was admitted to a gynecology hospital in her 6th month of pregnancy for high blood pressure and tonic-clonic seizure. primary diagnosis was eclampsia, and for that reason she underwent cesarean section. she also had headache on frontal and parietal areas without nausea or vomiting. there was not a focal neurological sign. rheumatology consultation was requested. systemic lup...

Unilateral selective cerebral perfusion through right brachial artery is one of the cerebral protection methods for aortic arch repair. The purpose of this study is to determine whether cerebral perfusion through contra-lateral hemisphere is adequate or not. Seventeen consecutive patients underwent aortic arch repair using low flow antegrade selective cerebral perfusion (ASCP) through right bra...

BACKGROUND Parametric-colored digital subtraction angiography using Tmax is almost a routine angiographic imaging procedure, currently. The current feasibility study is aimed to using the imaging to monitor treatment effects while embolizing indirect carotid-cavernous fistulas (CCF). METHODS Ten patients with CCFs receiving embolization and 40 patients with normal circulation time were recrui...

introduction: the present study evaluated morphological changes of ca1 hippocampal neurons following transient bilateral common carotid and permanent left middle cerebral arteries occlusion, also the neuroprotective effects of aspirin i.p injection was inducing assessed after ischemia in male rat. material and methods: in this experiment, 4 groups of animals were used including; control, sham, ...
