ABSTRACT
Objective To investigate the risk factors of perivascular space change after brain tumor surgery.Methods According to the occurrence of postoperative perivascular space change,80 cases of glioma patients were divided into perivascular space and reconstruction group(observation group,n=38)and normal postoperative perivascular space group(control group,n=42).Compared the general data,sur-gery,tumor related indicators and postoperative complications of the two groups,and analyzed the influencing factors of the perivascular space changes after brain tumor surgery.Results In the observation group,the operation time of the patients was(95.38 ±9.21)min,which was significantly longer than(75.36 ±9.05)min in the control group.The intraoperative blood loss was(290.32 ±45.47)mL in the observation group,which was significantly more than(247.19 ±36.75)mL in the control group,and the difference was statistically significant (P<0.05).The tumor site located in the left hemisphere,tumor volume more than 40.0 cm3,high grade glioma,and proportion of patients with postoperative complications in the observation group were all higher than those of the control group,and the difference between the two groups was statistically significant(P<0.05).Multivariate Logistic regression analysis showed that age,tumor location,tumor volume,patho-logical grade and complications were significantly correlated with the changes of perivascular space after surgery(P<0.05).Conclusion Advanced age,tumor located in the left side of the brain,large tumor volume,severe pathology,postoperative epilepsy,chronic intracranial hy-pertension and other complications were the risk factors affecting the changes of perivascular space in patients with glioma.
