本文提出了一种经济可靠的微腺瘤诊断及瘤体立体定位方法(包括蝶鞍侧位片及CT轴面薄层增强扫描加冠、矢状重建),能够直接而确切显示微腺瘤在鞍内的方位及其与鞍底和蝶窦的立体关系。经对40例垂体微腺瘤的应用,显示此法定位准确、可靠。根据定位资料进行手术,均取得优良效果,术后内分泌及CT随访均痊愈或好转,无死亡,无严重合并症及垂体功能低下。 This paper presents an economical and reliable diagnosis of micro-adenoma and tumor stereotaxic methods (including the lateral septa and CT axial thin-slice enhanced coronary crown scan, sagittal reconstruction), can directly and accurately show the microadenomas in the saddle Within the azimuth and its relationship with the sella and sphenoid sinus. The application of 40 cases of pituitary adenoma showed that this method is accurate and reliable positioning. According to the positioning data for surgery, we achieved good results. Postoperative endocrine and CT follow-up were cured or improved, no death, no serious complications and pituitary dysfunction.
