RESUMO
Objective To analyze the epidemiological characteristics of pituitary apoplexy and investigate the changes and features of endocrine hormones caused by pituitary apoplexy.Methods A retrospective analysis of the clinical and laboratory data of pituitary tumor and pituitary apoplexy was carried out.Results (1) The incidence of pituitary apoplexy was 31.78％,patients were 15-75 (47.5 ± 11.7) year old,most patients were female.(2)Diabetes,coronary heart disease,menopausal hormone therapy,radiotherapy,surgery,and bromocriptine administration may be related to pituitary apoplexy.(3) There was high incidence of apoplexy in nonfunctioning adenoma.(4) According to the relationship between apoplexy and pituitary tumor,cases with pituitary apoplexy were divided into 5 types.(5) Pituitary apoplexy was associated with low serum creatinine,hypernatremia,hyperchloremia,hypoeosinophilia,and hypobasophilia.(6) 61.61％ of the patients had pituitary hormone deficiency,especially the GnH deficiency.(7)98.10％ of the patients were treated by surgery.Conclusion Pituitary apoplexy has its own clinical characteristics,and more attention should be paid in clinical practice.
