To explore the prevention and treatment of surgical complications of anterior clinoid meningioma (ACM).

The clinical data of 63 patients with ACM treated by Chen Lihua from July 1999 to June 2021 were analyzed retrospectively. On the basis of Al-Mefty classification standard, ACM was divided into 4 types. According to the preoperative imaging examination, there were 7 cases (11.1%) of type Ⅰ tumors, 39 cases (61.9%) of type Ⅱ tumors, 5 cases (7.9%) of type Ⅲ tumors and 12 cases (19.0%) of type Ⅳ tumors. According to the preoperative tumor classification, corresponding measures were taken to prevent and treat complications, and the main factors affecting postoperative complications were analyzed.

Twenty-five patients had different degrees of complications after surgery, iof which 13 were more serious. The main complications were vision deterioration in 5 cases (7.94%), early oculomotor paralysis in 3 cases (4.76%), light hemiparesis in 4 cases (6.35%) and intracranial infection in 1 case (1.59%). The total incidence of major complications after surgery was 20.6% (13/63), and 6.35% (4/63) for permanent complications. There were no deaths. The univariate analysis showed that the type of tumor, the size of the tumor, the grade of the relationship between tumor and vessels, and the involvement of the cavernous sinus were the main factors affecting postoperative complications.

The total resection of ACM should take a positive and cautious attitude. According to the characteristics of different types of ACM, making a detailed surgical plan and using appropriate surgical techniques during the operation are the guarantee of reducing surgical complications and improving the overall prognosis.
