报告20例鞍结节脑膜瘤,行肿瘤全切除16例,大部切除4例,术后死亡3例,作者体会若肿瘤与脑底周围结构粘连过紧,全切除肿瘤是很困难的。对较大肿瘤采用冠状切口,双额开颅显露好,先分块或囊内切除一部分肿瘤后,再分离肿瘤后面的大脑前动脉和垂体柄等结构,可减少周围结构的损伤,并可提高全切除率。 Report of 20 cases of saddle nodular meningioma, the total removal of tumor in 16 cases, 4 cases of most resection, 3 cases of postoperative death, the author learned that if the tumor and brain around the structure of the adhesion is too tight, the total removal of the tumor is very difficult. For larger tumors using coronary incision, double craniotomy revealed a good first block or intracapsular excision of some tumors, and then separation of the tumor behind the anterior cerebral artery and pituitary stalk and other structures can reduce the surrounding structural damage and improve Total resection rate.
