Recovery of the Hypothalamo-Pituitary-Adrenal Axis After Transsphenoidal Adenomectomy for Non-ACTH-Secreting Macroadenomas
CONTEXT: Secondary adrenal insufficiency is a potential complication of transsphenoidal adenomectomy (TSA). Most centers test recovery of the hypothalamo-pituitary-adrenal (HPA) axis after TSA, but, to our knowledge, there are no data predicting likelihood of recovery or the frequency of later recovery of HPA function. OBJECTIVE: To assess timing and predictors of HPA axis recovery after TSA. DESIGN: Single-center, retrospective analysis of consecutive pituitary surgeries performed between February 2015 and September 2018.
