Original ArticleEndoscopic Endonasal Surgery for Treatment of Pituitary Apoplexy: 16 Years of Experience in a Specialized Pituitary Center

ObjectiveSymptomatic 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.MethodsWe 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.ResultsA 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.ConclusionsThe 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.
