Preoperative Evaluation of Collateral Venous Anastomoses in Meningioma Involving Cerebral Venous Sinus by Susceptibility Weighted Imaging

Precise preoperative identification of the collateral venous anastomoses is critical for proper surgical management of patients with meningioma involving sinus. This study was to assess the feasibility of susceptibility weighted imaging (SWI) to delineate the collateral venous anastomoses before surgery. Twenty-five patients with meningiomas that were involved in sinuses underwent surgery and t...

Re: Cerebral air embolism following removal of central venous catheter.

Cerebral air embolism occurs very seldom as a complication of central venous catheterization. We report a 57-year-old female with cerebral air embolism secondary to removal of a central venous catheter (CVC). The patient was treated with supportive measures and recovered well with minimal long-term injury. The prevention of air embolism related to central venous catheterization is discussed.

Teaching neuroImages: Cerebral and cervical venous air embolism.

A brain CT, performed because of subacute pain and weakness in the left arm of a 61-year-old man, revealed cerebral and faciocervical venous gas emboli (figures 1 and 2). A peripheral IV catheter had been placed 2 hours prior to CT without incident of disconnection. A second CT, performed 2 hours later, showed only persistent gas in the cavernous sinus. Twelve days later, CT was normal. Transth...

HBO is the most effectivetreatment of air embolism; it reduces the size of air bubbles and counteracts the secondary etTects. This chapter on cerebral air embolism examines: Causes .
