Complications of detachable balloon catheter technique in the treatment of traumatic intracranial arteriovenous fistulas.

As carotid-cavernous sinus fistulas (CCSF) are not life-threatening, therapeutic attempts should carry a very low morbidity and mortality. The authors believe that utilization of detachable balloons is the treatment of choice for CCSF, although this procedure is not without risk. Seven patients have been treated for high-flow traumatic intracranial fistulas over the past 2 years with detachable balloons using a coaxial catheter system. This paper presents several complications that have been encountered during this experience, and advances suggestions regarding treatment and avoidance of potential complications.

Pituitary adenomas producing growth hormone, prolactin, and one or more glycoprotein hormones: a histologic, immunohistochemical, and ultrastructural study of four surgically removed tumors.

The morphologic features of four pituitary adenomas, removed from 2 men and 2 women between 31 and 62 years of age, are reported. The tumors contained growth hormone (GH), prolactin (PRL), and one or more glycoprotein hormones--usually thyrotropin (TSH). Three tumors were associated with acromegaly and one with hyperprolactinemia. Hyperthyroidism was not evident in any of the patients. In the tumors of acromegalic subjects, GH-containing cells were the most numerous, whereas PRL cells were dominant in the adenoma accompanied by hyperprolactinemia. Electron microscopy revealed plurimorphous tumors comprised of various proportions of morphologically different cell types: densely granulated GH cells, TSH-like cells, and the less common mammosomatotrophs and PRL cells. It is suggested that pituitary adenomas producing GH, PRL, and glycoprotein hormones derive from the same precursor; their immunocytochemical profile, fine structural appearance, and endocrine function may depend on the degree and direction of the cellular differentiation.

Value of computed tomographic myelography in the recognition of cervical herniated disk.

Three patients with cervical radicular symptoms and normal metrizamide myelograms underwent thin-section high-resolution computed tomographic scanning because of a strong clinical suspicion of herniated disk. Herniated disk was demonstrated in all three cases. In two, the disk protrusions were recognized only by computed tomographic myelography, and in the third case, the diagnosis was made with plain computed tomography and confirmed by computed tomographic myelography.
