Comparatıve assessment of thermal ınjury ınduced by bıpolar electrocautery systems ın a porcıne model.

Background: Bipolar electrocautery systems used during neurosurgical procedures have been shown to induce thermal injury to surrounding tissue. The goal of this study was to compare the thermal injury induced by two different systems commonly used in neurosurgical procedures (Silverglide by Stryker Corporation and SpetzlerMalis by Codman Neuro), with that of a newly introduced device (TRIOwand by NICO Corporation).

Methods: A farm swine underwent craniectomy and durotomy with subsequent exposure of cortical brain tissue.

The role of inflammation and potential use of sex steroids in intracranial aneurysms and subarachnoid hemorrhage.

Background: Aneurysmal subarachnoid hemorrhage (aSAH) continues to be a devastating neurological condition with a high risk of associated morbidity and mortality. Inflammation has been shown to increase the risk of complications associated with aSAH such as vasospasm and brain injury in animal models and humans. The goal of this review is to discuss the inflammatory mechanisms of aneurysm formation, rupture and vasospasm and explore the role of sex hormones in the inflammatory response to aSAH.
