近年来,由于CT和MRI的普及,鞍区肿瘤特别是垂体瘤的发现率越来越高,手术病人随之增多。显微技术的广泛应用使垂体瘤的全切率不断提高,手术死亡率亦明显下降。但同时鞍区肿瘤术后低钠血症的发生率较高,其治疗亦较为棘手,故早期诊断和有效治疗对预后至关重要。现将我科1994年9月 In recent years, due to the popularization of CT and MRI, the detection rate of sella area tumor, especially pituitary tumor is higher and higher, the number of surgical patients increases.
