Abstract:

Objective

To investigate the risk factors of hemorrhage associated with external ventricular drainage (EVD), and to provide theoretical basis for the prevention and early diagnosis and treatment of hemorrhage associated with EVD.

Methods

A retrospective analysis was made of 114 patients with extraventricular drainage surgery admitted to Neurosurgery Department of Fuyang Cancer Hospital from January 2018 to May 2021. They were divided into bleeding group (28 cases) and non bleeding group (86 cases) according to whether they had hemorrhage associated with EVD. The baseline data of the two groups were compared, and then the factors with statistical significance in univariate analysis were included in multivariate Logistic regression analysis to explore the independent risk factors of hemorrhage associated with EVD.

Results

The results of univariate analysis showed that the age, previous stroke rate, preoperative antiplatelet drug use rate, preoperative anticoagulant drug use rate and puncture times of patients in the bleeding group were higher than those in the non bleeding group, and the concurrent brain surgery rate was lower than in the non bleeding group, with significant differences (P<0.05). The results of multivariate Logistic regression analysis showed that the use of preoperative antiplatelet drugs (OR=7.205, 95%CI:2.243-23.144) was a protective factor, while the number of punctures (OR=2.473, 95%CI: 1.315-4.650) and concurrent craniocerebral surgery (OR=0.163, 95%CI: 0.038-0.702) was a possible independent protective factor for puncture tract hemorrhage after extraventricular drainage (P<0.05).

Conclusion

Preoperative use of antiplatelet drugs is a protective factor, while the number of puncture times and simultaneous craniocerebral surgery may be independent risk factors for puncture hemorrhage after extraventricular drainage, so attention should be paid to active prevention and early intervention in clinical practice.
