颅内蛛网膜囊肿显微手术治疗

目的：回顾性分析开颅显微手术治疗颅内蛛网膜囊肿的疗效。方法：应用显微外科手术治疗上述病例２８例，男１９例，女９例，平均年龄２３岁。结果：囊肿全切除１５例，次全切除６例，部分切除加脑池（或蛛网膜下腔）交通术７例。术后平均随访３年，患者症状与体征均有改善。ＣＴ随访２１例，１８例囊腔消失或明显缩小，２例稍有缩小，１例较术前无变化。结论：精细操作，防止囊肿破裂并尽量完整切除或大部分切除囊肿，充分建立囊腔与周围脑池之间交通是手术成功的关键。

MICROSURGICAL TREATMENT OF INTRACRANIAL ARACHNOID CYSTS

Objective:To retrospect the result of microsurgery of intracranial arachnoid cysts. Method:28 cases of this disease were treated with the microsurgery,there were 19 males and 9 females,averaging 23 years.Results:All 28 patients underwent microsurgery,the cyst was total removal in 15 cases and subtotal removal in 6 cases. Incomplete removal of the cyst walls altach the cystic cavity communicates with the subarachnoid space or brain cistern in 7 cases.The postoperative average follow up 3 years,CT scans(21 cases)showed 11 cases were completely obliterated,9 cases were decreased in size,1 case was unchanged postoperately.All patients symptoms and signs were markly improved after surgery.Conclusion:The authors realize that the cyst rupture can be avoided,the cyst can be total removal or its lining memberane was excised as completely as possible by meticulous micro operation. It was importent that the cystic cavity communicaties with the subarachnoid space or brain cistern.
