[Use of intravenous digital subtraction angiography in the preoperative diagnosis of hypophyseal tumors].
The authors report on examinations performed via intravenous digital subtraction angiography in 19 patients with tumours of the pituitary gland who had been subjected to transnasal/transethmoidal removal of the tumour. It is easy to verify the course of the internal carotid artery in the region of the sinus cavernosus and thus the measurable distance of the internal carotid artery from the median line, as well as displacements of horizontal segments of the anterior cerebral artery. It is possible to exclude aneurysms. Basing on these results, bilateral conventional angiography of the carotid artery can usually be omitted. In this manner, diagnostic risk can be significantly reduced.
