Does stent implantation improve the result of repeat embolization in recanalized aneurysms?

abstract：:We studied the impairment of autoregulation of cerebral blood flow (CBF) and its effect on the electrical activity of the brain during the development of chronic cerebral vasospasm after subarachnoid hemorrhage, using a vasospasm model in primates. Fourteen animals were divided into two groups: a clot group (8) and a ...
