    Abstract:
    OBJECTIVE: To analyze the relationship between invasive pituitary adenomas and cavernus sinus and cariod artery and to predict their surgical outcomes. METHODS: Totally 270 patients with pituitary tumors were investigated in this retrospective study, including 113 men and 157 women, with a mean age of 40.8 years. The mean disease history was 3.6 years. Pituitary microadenomas were diagnosed in 56 cases, macroadenomas in 118 cases, and hugeadenomas in 96 cases. Adrenocorticotropic hormone-releasing adenomas (Cushing's diseases) were diagnosed in 40 cases, growth hormone-releasing adenomas in 58 cases, prolactinomas in 57 cases, and non-functional pituitary adenomas in 115 cases. Transsphenoidal microsurgery were performed on 260 patients, while transcranial microsurgery on 6 patients. RESULTS: The percentage of invasive pituitary adenomas was about 3.6% in microadenomas, 20.4% in macroadenomas, and 61.4% in hugeadenomas. Rate of total removal was 94.1% in non-invasive pituitary adenomas, and was 58.8% in invasive pituitary adenomas. CONCLUSIONS: It is important to analyze the grade of invasive pituitary adenomas to improve the removal of pituitary adenomas, avoid injuring cariod artery, and increase the rate of total removal.
