Microsurgical Removal of Microcatheter in the Middle Cerebral Artery During Resection of an Arteriovenous Malformation Resection
Surgical resection is the current standard of therapy for the treatment of arteriovenous malformation (AVM). Endovascular embolization is commonly used as an adjunct prior to surgical resection because it is believed to reduce the risk of intraoperative bleeding. Embolization has been associated with other complications including visual deficits, vessel perforation, and catheter adhesion. Cathe...
متن کاملDistributions of local oxygen saturation and its response to changes of mean arterial blood pressure in the cerebral cortex adjacent to arteriovenous malformations.
BACKGROUND AND PURPOSE To test the hypothesis that neither "steal" as cortical ischemia caused by reduced perfusion pressure nor "breakthrough" on the grounds of loss of pressure autoregulation exist in brain tissue surrounding arteriovenous malformations (AVMs), we established patterns of cortical oxygen saturation (SO(2)) adjacent to AVMs and its behavior after alterations of mean arterial bl...
متن کاملCorrelation of pressure measurements with angiographic characteristics predisposing to hemorrhage and steal in cerebral arteriovenous malformations.
PURPOSE To determine whether there is a physiologic explanation for the predisposition of patients with certain angiographic characteristics to symptoms of hemorrhage and steal. METHODS Superselective transcatheter feeding arterial pressure and mean arterial pressure measurements were obtained before embolotherapy in 32 patients with cerebral arteriovenous malformations. Pressures were correl...
متن کاملSurgical Resection of a Progressive Giant Arteriovenous Malformation After 13-year Follow-Up
Giant arteriovenous malformation (AVM) is a complex and relatively rare congenital lesion with high morbidity and mortality. Its optimal treatment, however, remains controversial. Normal perfusion pressure breakthrough (NPPB) is a potentially devastating complication following surgical resection. Generally, strict blood pressure control is particularly recommended for preventing this phenomenon...
