In this paper, a brief information on factors taking role in intracranial air formation and tension pneumocephalus because of two cases epidural air formation and tension pneumocephalus following transsphenoidal operation is presented. Two cases were treated conservatively.
Between 1985 and 1993, we treated seven cases of optic nerve sheath meningiomas. The median age at onset of their symptoms was 42.14 years. All of the patients were aged between 27 and 60 females with a slowly progressive lesion. Computed tomography and/or magnetic resonance imaging were used as diagnostic procedure in our cases. We operated on using microsurgical techniques in all of these cases. Vision was preserved in the three of our cases. The definitive treatment for these lesions is surgical resection, although no single best plan for optimal management has been determined. The data indicate that only small anterior tumors may be removed with preservation of useful vision. With posterior circumferential tumors, there have been no cases of tumor removal with preservation of vision. A management strategy directed toward preservation of vision is discussed.
A case of vertebral arteriovenous fistula (VAF) caused by an angiographic catheter during coronary angiography in a 30-year-old female is presented. The patient complained about a roaring noise in her left ear. Preoperative and postoperative angiographic verification of the lesion is presented. The patient was treated by a direct surgical trapping of the vertebral artery (VA) proximal and distal to the fistula.
