Background: Pituitary apoplexy (PA) is the paradigm of endocrine and neurosurgical emergency.
Objective: To evaluate the comorbidities, risk factors, clinical presentation, pituitary apoplexy score (PAS), and the outcomes of surgical vs conservative management of PA in Spain.
Methods: Spanish multicenter, observational study of 301 patients with acute PA. Statistical analyses compared risk factors, clinical presentation, and outcomes between surgical and conservative treatment groups, adjusting for potential confounders. The prevalence of cardiovascular risk factors in patients with PA was compared with the Spanish population and with patients with nonfunctioning pituitary adenomas.
Results: Median age was 59.3 years, 201 (66.8%) were men; nonfunctioning adenomas (77.9%) were the most common tumor type. The prevalence of diabetes (20.3% vs 13.9%, P < .01), hypertension (48.8% vs 33.4%, P < .01), and dyslipidemia (44.2% vs 23.3%, P < .01), exceeded the Spanish age-adjusted population prevalence. Overall, 209 (69.4%) underwent surgery and 92 (30.6%) received conservative treatment. Surgical patients had larger tumors (26.2 vs 21.0 mm, P < .01), more frequent chiasmal compression (77.2% vs 53.4%, P < .01), and higher values of PAS. In the follow-up, although there were no statistically significant differences in anterior pituitary hormonal deficits between treatments, permanent vasopressin deficiency was more frequent after surgery (14.8% vs 3.3%, P < .01).
Conclusions: There is a high burden of cardiovascular risk factors among patients with PA, suggesting that metabolic factors may play a potential role in the development of PA. This underscores the need for comprehensive management of these conditions in addition to treating the apoplexy itself in this population. Surgical management has a relevant place in PA approach mainly in patients with higher PAS. However, it leads a permanent vasopressin deficit more frequently than a conservative approach.
