ABSTRACT
OBJECTIVE: Symptomatic pituitary apoplexy is a rare but life-threatening condition caused by sudden hemorrhage or infarction of a pituitary adenoma. In the current study, we aim to evaluate the clinical presentation, management, and clinical outcomes in a cohort of patients who were treated for this condition in our center in the last 16 years. METHODS: We performed a retrospective analysis of all patients who underwent endoscopic endonasal surgery for treatment of symptomatic pituitary apoplexy between 2001 and 2016 in our center. RESULTS: A total of 39 patients were included in the study, mean age of 54.9 years (range, 18-70 years) and mean follow-up 5.1 years (range, 0.6-16 years). Most of the patients had nonfunctioning adenomas (32 patients). Headache (89%), visual impairment (79%), and hypopituitarism (86%) were the most common preoperative findings. Surgical treatment led to gross total resection in 31 patients (79.4%). During follow-up, visual fields and oculomotor improvement was observed in 23 (74.1%) and 21 (67.7%) of the patients, respectively. Intractable headache also improved in all patients. Hypopituitarism was present in 77% of patients after surgery. In this series, no cerebrospinal fluid leak, vascular injury, or infection was observed. There was no postoperative mortality. CONCLUSIONS: The endoscopic endonasal transsphenoidal approach is an effective modality to treat pituitary apoplexy with a high rate of success and minimal risk in selected cases. Although reversion of preoperative visual deficits is often observed, hormonal deficits tend to persist, and require long-term hormonal therapy, even after successful endoscopic endonasal surgical resection.
