The Utility of intravenous DSA for cavernous sinus venography
Intravenous DSA (IVDSA) applied to an intracranial lesion, especially tumors around cavernous sinuses, can reveal the laterality of the sinus with minimal invasiveness. In this study, a total of 30 patients who had parasellar tumors were examined and preoperative information concerning the extent of tumor invasion was obtained. Pituitary adenomas and craniopharyngiomas seldom invade the cavernous sinus, whereas meningiomas and chordomas often invade it. IVDSA can offer information as a routine venogram of the cavernous sinus with a minimally invasive technique.
