THE ANGIOGRAPHIC DEMONSTRATION AND SURGICAL IMPLICATIONS OF IMBEDDING OF THE CAROTID SYPHONS BY A LARGE PITUITARY ADENOMA

Abstract
The distance between the carotid syphons usually is increased when there is lateral extension of a pituitary adenoma. Infrequently this distance is either diminished or remains normal. When this is associated with gross bone change in the sphenoid, there is a possibility that the tumor has enveloped the carotid arteries. Surgical evacuation of the intrasellar portion of such neoplasms must be performed with full appreciation of the medial position of the intracavernous portions of the internal carotid arteries.
