Persistent trigeminal artery: its relationship to the normal branches of the cavernous carotid

Abstract: ✓ The authors report a detailed study of an autopsy specimen indicating that the meningohypophyseal trunk and a persistent trigeminal artery apparently exist independently and have separate origins.

Intracranial sympathetic pathways associated with the sixth cranial nerve

Abstract: ✓ During a continuing study of the anatomy of the parasellar region, a macroscopically identifiable nerve has been observed to leave the foramen lacerum and join the abducens nerve within the cavernous sinus. A description and photographic documentation of this sympathetic branch to the fifth cranial nerve by way of the sixth cranial nerve are presented.

Endarterial occlusion of carotid-cavernous sinus fistulas using a balloon tipped catheter.

Abstract: Endarterial occlusion of carotid-cavernous fistulas using a balloon tipped catheter seems to be, at present, the best technique for the definitive treatment of the disorder without any sequela. A Fogarty catheter is placed in the internal carotid artery to reach the carotid siphon; the balloon is inflated at the orifice of the fistula and left there. Clinical results are excellent. In case of insufficient occlusion, a second balloon can be placed.

Presistent trigeminal artery. An autopsy report.

Abstract: The anatomical features of a left persistent trigeminal artery, found incidentally at autopsy, are reported. In spite of the close relationship to the Gasserian ganglion and to the cavernous sinus no mutual effect upon of from these structures can be shown. However, penetration of the anastomosis through the clivus under the left posterior clinoid process of the sella caused a conspicuous atrophy of that process.

Malignant Pituitary Adenoma: A Cause of Sphenoid Hyperostosis and Monocular Blindness

Abstract: Malignant pituitary adenomas are extremely rare and comprise less than 5% of all pituitary tumors. A 65-year-old woman had rapid loss of vision and a chiasmal syndrome. Investigation revealed panhypopituitarism, and hyperostosis of the greater wing of the sphenoid bone and x-ray film evidence suggested a tuberculum sella meningioma. When a craniotomy was performed, a pituitary adenoma was found. The patient's death one month later was caused by an abnormal antidiuretic hormone (ADH) syndrome and pulmonary emboli. Pathological examination revealed an invasive pituitary adenoma, involving the optic nerves and cavernous sinus. The hyperostosis seemed to correlate well with the tumor infiltration. There were, however, no clinical or radiological findings that were diagnostic of malignant pituitary adenomas. The diagnosis of malignant adenomas should be considered when visual loss is rapid or when there are signs of extension into the cavernous sinus.

Originals Cavernous Sinus Venography by Transbasilic Catheter Technique

Abstract: The purpose of this paper is to present a new, possibly preferable method for cavernous sinus and orbital venography, by retrograde catheterization from the arm. With this procedure, good opacification of cavernous sinus may be offered also in patients who have heart diseases. This procedure can be tolerated with minimal discomfort. The patterns of the cavernous sinus are demonstrated in those with intracranial diseases. There have been no complications in our initial experience of 28 examinations.

Radiological Assessment of the Pituitary Gland

Abstract: The treatment of pituitary gland tumours, particularly where there is no clinical evidence of supra-sellar extension, rarely involves an open surgical procedure. In these cases, pituitary ablation can be carried out by one of several methods including trans-sphenoidal and transethmoidal hypophysectomy, trans-sphenoidal cryosurgery, trans-sphenoidal yttrium implantation, external irradiation and transfrontal stereotactic yttrium implantation. Irrespective of the method employed, accurate investigation of the pituitary gland is essential, but this is particularly important with stereotactic implantation.
