Transcavernous surgery; an effective treatment for pituitary macroadenomas
European Journal of Endocrinology
|August 1, 1995
Summary
Transcranial transcavernous surgery significantly improves hormone levels in patients with pituitary macroadenomas invading the cavernous sinus compared to transsphenoidal surgery. This approach offers better tumor removal and endocrinological outcomes.
Area of Science:
- Neurosurgery
- Endocrinology
- Oncology
Background:
- Pituitary macroadenomas invading the cavernous sinus present surgical challenges.
- Evaluating surgical approaches for optimal endocrinological outcomes is crucial.
Observation:
- Four patients with cavernous sinus-invading pituitary macroadenomas underwent transcranial transcavernous surgery.
- Four patients with similar macroadenomas were treated with transsphenoidal surgery.
Findings:
- Transcranial transcavernous surgery resulted in a 58.4%–90.1% decrease in elevated anterior pituitary hormones.
- Transsphenoidal surgery showed a 0%–46.1% decrease in hormone levels.
- Hormone responsiveness was restored post-transcranial transcavernous surgery, unlike transsphenoidal surgery.
- Transsphenoidal surgery provided insufficient tumor reduction and endocrinological remission.
Implications:
- Transcranial transcavernous surgery is recommended for pituitary macroadenomas with suspected cavernous sinus invasion.
- This approach facilitates significant tumor extirpation and endocrinological improvement.
- It is particularly effective for somatotroph or corticotroph macroadenomas.
- Potential mild cranial nerve paresis is transient, resolving within 1-4 months.
