Influencing factors of postoperative complications of longitudinal fissure meningioma / 局解手术学杂志

ABSTRACT

Objective To evaluate the risk of microsurgery and reduce the incidence of postoperative complications in patients with lon-gitudinal fissure meningioma. Methods The clinical data of 106 patients with longitudinal fissure meningioma after microsurgery in the neu-rosurgery department of Xuzhou medical university from January 2011 to December 2017 were retrospectively analyzed.Longitudinal fissure meningioma were defined as the meningioma whose base were attached to the brain’s sickle sinus,sagittal sinus and the brain’s sickle sagit-tal sinus.Patients were divided into two groups according to whether there were postoperative complications.The gender,age,chief complaint symptoms,tumor base,tumor location,tumor size,tumor shape,MR enhancement,MR peritoneal edema, peritoneal adhesion of central sulcus vein and drainage vein,tumor invasiveness,tumor boundary,previous history of circulatory system were compared.Univariate analysis was per-formed on these factors to screen out the influencing factors of patients with postoperative complications.Binary logistic regression analysis was performed on the factors with statistical significance.Results Central sulcus vein and drainage vein adhesion were independent protective factors for postoperative complications.The risk of postoperative complications in patients without adhesion at peri-tumor stage was only 0.209 times of that in patients with adhesion.Conclusion For patients with longitudinal fissure meningioma,preoperative risk of postoperative com-plications can be assessed objectively according to the condition of central sulcus vein and drainage vein adhesion around the tumor.In the treatment of patients with obvious peritumoral vascular adhesion,the central sulcus vein and drainage vessels should be carefully protected to significantly reduce the incidence of postoperative complications.
