颅咽管瘤侵袭第三脑室的方式对手术切除的影响

Objective To assess the impact of the positional relationship between the large craniopharyngiomas and the third ventricle on the outcome of surgical resection of the tumors. Methods In 72 cases of craniopharyngiomas, the tumors were classified into two types according to the radiographic and surgical findings defining the relationship between the tumors and the third ventricle. For each type of tumors, 3 grades were classified based on the tumor size, texture, and infiltration pattern of the third ventricle. The extend of tumor removal was confirmed by both intraoperative evaluation and postoperative CT or magnetic resonance imaging. The correlation between the degree of hypothalamus invasion and the extend of tumor removal was analyzed in all the cases. Results The craniopharyngiomas were classified into two types, namely those residing in the third ventricle (7 cases) and those invading the third ventricle(65 cases). The degree of tumor resection was significantly different between the 3 grades: total tumor removal was achieved in 95.7% of grade Ⅰ cases, in 80.0% of grade Ⅱ cases, and in only 47.4% of grade Ⅲ I cases (P<0.05). conclusion Understanding of the anatomical relationship of the tumor to the third ventricular floor can be great value for improving the outcome of surgical resection of large craniopharyngiomas.     

颅咽管瘤侵袭第三脑室的方式对手术切除的影响

目的 探讨大型颅咽管瘤与第三脑室的关系在肿瘤切除手术中的意义. 方法 南方医科大学南方医院神经外科白1997年1月至2003年1月共采用手术治疗大型颅咽管瘤患者72例.根据肿瘤的影像学表现及手术所见对其进行分类,每一类肿瘤根据大小及其与第三腩室底的关系分为3级,根据术中判断和术后CT和(或)MPd增强扫描结果确定颅咽管瘤手术切除程度,分析肿瘤分级与手术切除程度的关系. 结果颅咽管瘤总体上可以分为第三脑室内型(本组7例)和第三脑室累及型(本组65例)两大类;手术切除程度在不同分级肿瘤间总体分布位置不同,差异有统计学意义(P<0.05). 结论 明确大型颅咽管瘤与第三脑室底及下丘腩结构间的关系对提高大型颅咽管瘤手术疗效有重要意义.     

鞍隔孔区解剖学研究及其临床意义

目的 通过鞍隔孔区结构的解剖学研究,分析经蝶入路脑脊液漏的发生机制,以及空蝶鞍(ES)的形成原因. 方法 对8例胎儿标本进行组织学连续切片后,做HE和Masson染色,并在显微镜下对鞍隔孔附近结构进行观察;另取10例成人尸头标本,模拟经蝶入路手术,并在手术显微镜下观察鞍隔孔区解剖结构. 结果 鞍上蛛网膜在垂体柄上端和其表面的软脑膜紧密结合,并转折进入鞍内;同时在垂体上表面处,鞍隔从四周紧密包绕并和表面的软脑膜紧密结合,而难以从组织学切片上分辨二者的界限:鞍上蛛网膜池由于蛛网膜、软脑膜和鞍隔的束缚而终止于鞍隔孔上部. 结论 鞍隔、软脑膜和鞍上蛛网膜三者之间存在着严密的解剖学关系,其也是防止脑脊液漏和ES发生的关键因素.这三者的先天性缺损、生理性或者病理性破坏,尤其是在经蝶入路中对垂体腺瘤的过分牵拉,导致鞍上蛛网膜和软脑膜分离或者破裂,可能是造成术中脑脊液漏发生的重要原因;另外鞍隔、软脑膜和垂体上表面之间的分离也可能是造成ES的关键因素.

从“土克水”角度认识“骨痿”

原发性骨质疏松症(primary osteoporosis,POP)是一种以骨量低下、骨微结构破坏,导致骨脆性增加、易发生骨折为特征的全身性骨病,在现代中医学中属于"骨痿"范畴,肾水亏虚是本病基础,并与肝木、脾土相关,除了补肾壮骨之外,黄帝内经创造性地提出了"治痿独取阳明"治疗大法,本文将通过五行"土克水"的角度重新梳理"骨痿"的病因病机,并在主流治疗方案之外创新性地提出了独特的治法治则,兹可作为现代中医治疗"骨痿"的一个重要补充。
