This article reported clinical experience of the surgical managemets of suprasellarmeningiomas for 41 cases. Total removal of the tumor was achieved in 29 cases, subtotal excision in 8cases, great partiai excision in 4 cases, and surgical mortality in 4 cases. 26 cases were followed up3-108 months with no recurrence. By microsurgical technique, the relationship of the tumor and thesurroundjng structures such as intemal carotid artery, anterior cerebral artery, optic nerve, hypothalamus,hypophyseal stalk and optic chiasma was clear in the operative field. The total tumor resection rate couldbe raised. The mortality rate could be reduced.

本文报告41例鞍上脑膜瘤外科手术切除的临床经验,其中全切除29例,次全切除8例,大部分切除4例,死亡4例.26例经3个月-9年术后随访,肿瘤无复发.采用显微外科手术,术野清楚,能正确辨认鞍上肿瘤与颈内动脉、大脑前动脉、视神经、下丘脑、垂体柄和视交叉等重要结构关系,提高了肿瘤全切除率,降低了死亡率。

Objective:To explore the abnormal variations of important structures surrounding the large and huge pituitary adenomas.Methods:Abnormal conditions during microsurgery on 19 patients with large and huge pituitary adenoma were observed. Results: 1)All optic nerves, and optic chiasmas were pushed,compressed and elevated.Adhesion occurred between some of the nerves and the tumor. 2)Diaphragm sella was pushed up by the tumor.The location of diaphragm sella where the small tumor grew up was damaged.The hypophyseal...

Objective:To explore the abnormal variations of important structures surrounding the large and huge pituitary adenomas.Methods:Abnormal conditions during microsurgery on 19 patients with large and huge pituitary adenoma were observed. Results: 1)All optic nerves, and optic chiasmas were pushed,compressed and elevated.Adhesion occurred between some of the nerves and the tumor. 2)Diaphragm sella was pushed up by the tumor.The location of diaphragm sella where the small tumor grew up was damaged.The hypophyseal stalk was depressed down in the posteroinferior part of the diaphragm sella. 3)The chiasmatic cistern was not intact.At some parts of this cistern, the subarachnoid space disappeared.At other parts of this cistern,where the arteriae were compressed or surrounded by the tumor,there were crevices instead of cistern. 4)There were some new tumor vessels coming from meninges,nerves,and arteriae. Conclusion:Important structures surrounding the large and huge pituitary adenomas are compressed and adhered by the tumors.Some parts of the subarachnoid space disappear.Some new tumor vessels emerge from the surrounding structures.All the above conditions are related to the size and growing directions of tumors.Operation results may be improved if the abnormal variations are recognized and well handled.

目的:探查大型、巨大型垂体腺瘤周围重要结构的变异情况。方法:在19例垂体瘤病人进行显微手术切除术时,观察其变异情况。结果:1)视神经、视交叉全部被牵拉、受压、抬高,部分与肿瘤发生粘连。2)鞍膈全部向上隆起,在肿瘤上长出分叶的小肿瘤处鞍膈破溃。垂体柄被挤压在鞍膈的后下方。3)视交叉池不完整,在粘连及垂体柄进入鞍膈处,蛛网膜下腔已经消失;在肿瘤挤压(包括动脉)处,蛛网膜下腔仅为一潜在腔隙。4)凡被肿瘤挤压、包围、发生粘连的硬脑膜、神经及血管均有肿瘤新生血管形成。结论:大型、巨大型垂体腺瘤对周围重要结构产生挤压,发生粘连,部分蛛网膜下腔消失,并有肿瘤新生血管形成。以上异常与肿瘤大小及生长方向直接相关。了解上述规律,有利于提高手术疗效

Purpose:To analyse the MR manifestations and clinical significance of Empty Sella Syndrome(ESS).Materials and Methods:Thirty four cases of ESS were diagnosed by a MR system.It can be divided into the Ⅰ and the Ⅱtypes,according to the degree of compression of the pituitary.The Ⅰ type of ESS was compared with the Ⅱtypes on the MR findings and clinical manifestations.Results:ESS appeared as hypophyseal stalk retroposition in 7 cases (7/20) and optic chiasm elevation in 3 cases (3/20),which were graded as...

Purpose:To analyse the MR manifestations and clinical significance of Empty Sella Syndrome(ESS).Materials and Methods:Thirty four cases of ESS were diagnosed by a MR system.It can be divided into the Ⅰ and the Ⅱtypes,according to the degree of compression of the pituitary.The Ⅰ type of ESS was compared with the Ⅱtypes on the MR findings and clinical manifestations.Results:ESS appeared as hypophyseal stalk retroposition in 7 cases (7/20) and optic chiasm elevation in 3 cases (3/20),which were graded as the Ⅰ type;hypophyseal stalk retroposition in 11 cases(11/14),optic chiasm elevation in 8 cases(8/14),they were graded as the Ⅱ type,both ESS were significantly different(P<001).Isointence signal of neurohypophysis were significantly higher in the Ⅱ type than the Ⅰ type.However,both types of ESS were not significantly different in main clinical findings.Conclusion:MR manifestations and classfication of ESS have diffinitive referential value from the point of view of clinical recognization and management.

目的:分析空蝶鞍综合征(ESS)MR表现及临床意义。材料和方法:经MRI诊断为ESS者34例,根据垂体压缩程度分Ⅰ、Ⅱ两型。比较两型的MR所见和临床表现。结果:Ⅰ型ESS显示垂体柄后移7例,占35%(7/20),视交叉上抬3例,占15%(3/20);Ⅱ型ESS显示垂体柄后移11例,占78%(11/14),视交叉上抬8例,占57%(8/14),二者有明显统计学差异(P<0.01)。Ⅱ型ESS的垂体后叶信号变为等信号的发生率比Ⅰ型高。但比较Ⅰ型与Ⅱ型的主要临床表现无有意义差别。结论:ESS的MR表现及分型对临床认识和处理本病有一定参考价值。
