Overview
Common risk factors in the development of pituitary apoplexy include bleeding disorders, diabetes, head injury, radiation to the pituitary gland, use of a breathing machine, angiography and surgery.
Risk Factors
Common risk factors in the development of pituitary apoplexy include :
- Bleeding disorders[1]
- Diabetes
- Head injury
- Radiation to the pituitary gland
- Use of a breathing machine
- Angiography [1]
- Surgery leading to hypotension and subsequent hypoperfusion of the pituitary gland.[1]
- Pituitary stimulation with ACTH, TRH or GnRH analogues.
- Pregnancy leads to increased pituitary volume secondary to lactotroph hyperplasia, which returns to normal six months post-partum. Estrogen induced increased blood flow to pituitary.
