Pre-stroke surgery is not beneficial to normotensive rats undergoing sixty minutes of transient focal cerebral ischemia.

ABSTRACT: Experimental stroke in rodents, via middle cerebral artery occlusion (MCAO), can be associated with a negative impact on wellbeing and mortality. In hypertensive rodents, pre-stroke craniotomy increased survival and decreased body weight loss post-MCAO. Here we determined the effect, in normotensive Sprague-Dawley rats following 60 minutes MCAO, with or without pre-surgical craniotomy, on post-stroke outcomes in terms of weight loss, neurological deficit, lesion volume and functional outcomes. There was no effect of pre-stroke craniotomy on indicators of wellbeing including survival rate (P = 0.32), body weight loss (P = 0.42) and neurological deficit (P = 0.75). We also assessed common outcome measures following experimental stroke and found no effect of pre-stroke craniotomy on lesion vo
