大型,巨大型垂体腺瘤血运情况显微解剖初步研究

采用显微手术方法，探索１６例大型，巨大型垂体腺瘤的供血规律。结果显示：巨大垂体腺供血除垂体上，下动脉下，还有来自硬脑膜、视神经、视交叉及周围动脉的新生血管供血。表明巨大垂体腺瘤的供血情况明显增加。

A primary study of microanatomy on blood supplement of large and huge pituitary adenoma]

OBJECTIVE: To explore the blood supplement regularity of large and huge pituitary adenomas. MECHODS: Sixteen large and huge pituitary adenomas were removed by microsurgery via transorbitofrontosphenoidal approach. The blood vessels of the tumors coming from surrounding structures were observed, photographed, videotaped and measured during operation. RESULTS: The blood supplement of the pituitary adenoma comes from not only the superior and inferior hypophyseal arteries, but also a lot of new arteries originating from meninges, optic nerves, optic chiasm, and arteries which surround the tumors, such as internal carotid artery, anterior cerebral artery and soon. CONCLUSION: The blood supplement of large and huge pituitary adenomas is increased obviously. The operation results will get much better if this situation is recognized and handled very well.
