垂体腺瘤如向鞍隔、硬脑膜、颅骨、邻近的静脉窦等部位侵袭生长,即称为侵袭性垂体腺瘤。由于临床上发现的侵袭性垂体腺瘤瘤体一般都比较大,在鞍区又呈浸袭性生长,与视神经、视交叉、颈内动脉、海绵窦、垂体柄及视丘下部等重要结构关系密切,因而全切除难度较大,切除不彻底术后容易复发。近几年来,我们采用经翼点入路显微外科技术,切除浸袭性垂体腺瘤18例(占同期垂体腺瘤的18％),取得较好的疗效,现总结、分析如下。
Pituitary adenomas such as invading the saddle septum, dura mater, skull, adjacent venous sinus and other parts of the invasion, that is, invasive pituitary adenoma. As the clinically found invasive pituitary adenoma tumors are generally larger, they are also immersed in the saddle area and have important structural relationships with the optic nerve, optic chiasm, internal carotid artery, cavernous sinus, pituitary stalk, and hypothalamus. Close, so the total removal is more difficult, resection is not completely easy to relapse. In recent years, we have adopted a pterional approach microsurgical technique to remove 18 cases of invasive pituitary adenomas (accounting for 18% of pituitary adenomas in the same period) and achieved good results. The summary and analysis are as follows.
