Early and late results of neurosurgical treatment with Itsenko-Cushing disease

Abstract

То study the efficiency of neurosurgical treatment of the Itsenko-Cushing disease (1CD), the authors analyzed the early and late results of adenomectomy in 99 patients (90 females and 9 males) with ICD. The diagnosis of ICD was verified on the basis of hormonal studies, functional tests, and the results of topic diagnosis. All the patients had an active stage of the disease and a pituitary tumor, as evidenced by magnetic resonance Imaging (MRI). Out of the 99 patients, 75% had a microadenoma of the pituitary and 25% had its macroadenoma. No correlation was found between the sizes of a tumor, the duration of the disease, and the severity of hy-percorticism. The Indication for surgery was a well-defined localized pituitary tumor as verified by MRI. The patients tolerated a neurosurgery well and complications as incoming diabetes insipidus were observed only in 12%, which is in agreement with the data available in the literature. Algorithms were developed for postoperative management of these patients. The findings have indicated that the development of the hormonal and clinical signs of hypocorticism serves as a good predictive marker of a radically performed operation. Six months after surgery, 82% of the patients were at remission. At an average 8.6-year follow-up, remission continued to be in 69(85.2%) of 81 patients. After surgery, patients with ICD should be, however, followed up since 14% developed a recurrence in the late postoperative period.
