Case ReportsDural arteriovenous fistulae: noninvasive diagnosis with dynamic MR digital subtraction angiography.
MR digital subtraction angiography (DSA) is a new diagnostic tool capable of producing dynamic images of the cerebral circulation with the injection of gadopentetate dimeglumine into a peripheral vein. Previous reports have concentrated on its potential as a noninvasive technique for the study of pial arteriovenous malformations. In this report, we present our early findings with MR DSA in the evaluation of intracranial dural arteriovenous fistulae.

Case ReportsTreatment of iatrogenic internal carotid artery laceration and carotid cavernous fistula with endovascular stent-graft placement.
The risk of fatal injury of the internal carotid artery (ICA) and surrounding anatomy during transsphenoidal surgery for pituitary adenoma is the most severe potential complication associated with this particular approach. We present a case in which iatrogenic injury to a patient's ICA and resultant carotid cavernous fistula and massive hemorrhage was successfully managed with the emergency placement of an endovascular stent-graft. Both findings in the relevant literature and practical considerations concerning both stent-grafts and other more commonly used options for the treatment of iatrogenic ICA injury are discussed.
