Diagnosis and new treatment options for pituitary adenomas

Abstract

Currently, the treatment of pituitary adenomas is inextricably linked with transsphenoidal neurosurgical intervention. Modern technologies used in surgery for this pituitary pathology, such as endoscopy using angled optics, as well as the use of specialized instruments, sealing and hemostatic materials, increase the effectiveness of surgical treatment of pituitary adenomas and reduce the incidence of intraand postoperative complications. The development of radiation methods of diagnostics, such as MRI, makes it possible to more accurately identify the formation of the pituitary gland, assess its size, direction of growth, and the degree of invasion of surrounding tissues. The authors of the article described in detail the modern technique of transsphenoidal removal of pituitary adenoma using an endoscope. Each stage of the operation is described step by step, taking into account various anatomical features and illustrated. This article discusses the MRI characteristics of pituitary adenomas: size of the tumor, the direction of its growth, the degree of invasion of the cavernous sinuses, the compression effect on the structures of the chiasmal-sellar region. The use of treatment methods, knowledge of the features of MRI diagnostics described in this article greatly increase the effectiveness of the treatment of patients with pituitary adenomas and reduce the risk of complications after neurosurgical intervention in such patients.
