经颅低强度钬激光手术切除大型垂体腺瘤

The Transcranial Excision of Massive Pituitary Tumorwith HolmiumYAG Laser

为研究经颅低强度钬激光切除大型垂体腺瘤的临床效果，１８例大型垂体腺瘤经颅用低强度钬激光切除，其中２例在显微镜下全切除。结果，本法切除大型垂体腺瘤，尤其配备显微镜，使病变与周围组织显示清晰，能在很小的术野下，随意操纵光纤切割、汽化病变组织。结果表明，钬激光用于颅内肿瘤切除，特别是在显微镜下更为安全有效。

n order to study the clinical effect of excision of massive pituitary tumor with low energy holmiumYAG laser, 18 cases of massive pituitary tumors were excised with low energy holmiumYAG laser, including 2 cases combined with microsurgery. With holmiumYAG laser, especially combined with microsurgery, the lesions can be well seperated from the surrounding structures, and the tumor can be excised and vaporized. Our findings indicate that holmiumYAG laser may be applied in brain tumor operation and it is more effective if used in combination with microsurgery.
