松果体区肿瘤显微手术治疗

Surgical treatment of pineal region tumors

２３例松果体区肿瘤进行显微手术治疗。其中１０例选用经幕下小脑上入路，７例经枕小脑幕上入路，６例经顶枕胼胝体切开入路。无手术死亡。术后复查头部ＣＴ证实肿瘤全切除１２例，部分切除１０例，肿瘤活检１例。指出术前应参照头部ＣＴ、ＭＲＩ，针对肿瘤与邻近解剖结构关系不同，选择适当的手术入路。

Abstract cases with pineal region tumors were operated with microsurgery. Infratentorial supracerebellar approach was adopted in 10 cases; the occipital transtentorial approach in 7 cases; Parieto-occipital transcallosal approach in 6 cases respectively. These tumors were resected totally in 52% cases and no mortality occur in the study. The authors pointed out that the characteristic shap of tumor demonstrated by neuroradiological images would be determine the selection of operative approach .
