【摘要】 目的 将鞍区及垂体血供的显微解剖知识应用于鞍区肿瘤的显微手术中,达到既减少术中血管损伤、又全切除肿瘤。方法 在手术显微镜下经翼点入路鞍区四个解剖间隙切除鞍区肿瘤88例,术中注意保护肿瘤周围的视神经、ICA及发出的垂体上动脉。结果 88例鞍区肿瘤,全切除84例(94.4％),死亡3例(3.4％),复发4例(4.5％)。结论 在经翼点入路行鞍区肿瘤的显微手术中,熟练掌握鞍区四个解剖间隙及垂体血供的显微解剖,是提高全切率、降低死亡及复发率的关键。更多还原

【Abstract】 Objective To introduce the experience in management of sellar region tumors. Methods Under the operative microscope, the sellar region tumors in the 88 patients were resected through the 4 anatomical spaces via transpterional approaches. Attention was paid to protecting the important structures including the optic never and ICA, and superior hypoph-yseal arteries. Results Complete tumors removal was achieved in 84 (84/88). The mortality was 3.4% (3/88) and tumor recurrence rate was 4.5% (4/88). Conclusion In dealing with sellar region tumors, a full understanding of the anatomy of the sellar region including hypophyseal 4 anatomic spaces and hypophyseal blood supply is of key importance for a neurosurgeon to obtain a higher tumor resecting rate and low mortality rate.更多还原
