脑膜瘤瘤周硬膜血管增生的影响因素以及其在凸面脑膜瘤切除中的作用

【摘要】:脑膜瘤的生长来源于蛛网膜细胞,其对硬脑膜的侵蚀特别是对硬膜血管的侵蚀导致了肿瘤的发育。我们通过对2012-2013年间42例病人(WHO Ⅰ级20例,WHO Ⅱ级18例,WHO Ⅲ级4例)的的影像学,病理学资料,结合术中所见,我们发现大部分凸面脑膜瘤的瘤周约15±3.8mm均存在围绕瘤体的连续或者不连续血管增生(WHO Ⅰ级20例,WHO Ⅱ级15例,WHO Ⅲ级4例),此类血管增生我们命名为“血管增生带”,其与脑膜瘤“尾征”的存在有着密切关系,此部分硬膜术后送病理切片均提示血管增生,沿血管增生带外缘切除肿瘤,可达到Simpson0级切除,提示血管增生带可作为凸面脑膜瘤中切除范围的标志。
