Intraoperative Embolization of Dural Carotid-Cavernous Fistula: Case Report

Among the twenty-six carotid-cavernous fistulas(CCFs) admitted to Yeungnam University Hospital from Nov. 1985 to Apr. 1994, we managed successfully by a intraoperative embolization of the cavernous sinus through the superior ophthalmic vein in two cases, which were not occluded the fistula site by the percutaneous transarterial and transvenous embolization. We exposed the cavernous sinus epidurally through the pterional approach and embolized the cavernous sinus with Surgical through the small opening at the junction of the superior ophthalmic vein entering the cavernous sinus. The surgical results were excellent.

The Effects of Microwave Irradiated on Rabbits' EEG

Microwaves may induce effect and damage on nervous tissue, either by thermal or mon-thermal mechnisms. EEGs were checked in left frontal lobe before and after irradiation of microwave at frequency of 2.45 GHz in 18 Rabbits. In results, mean total power of EEG was slightly decreased after irradiation of microwave. And mean composition percentage of delta wave was decreased and mean composition percentages of theta, alpha and beta wave were increased after irradiation in observation for 7 days. That mean decrease of electrophysiologic activity and trend of fast wave in brain after irradiation of microwave.
