摘要

目的

分析颅内动脉瘤（intracranial aneurysm，IA）夹闭术后发生迟发性脑梗死（delayed cerebral infarction，DCI）的危险因素及临床意义。

方法

回顾性分析2015年1月至2019年12月重庆医科大学附属第一医院神经外科收治的颅内动脉瘤患者的临床资料，纳入动脉瘤夹闭术患者共480例。其中发生DCI的患者设为观察组，共42例；未发生DCI的患者设为对照组，共438例；以单因素和多因素Logistic回归分析筛选发生DCI的危险因素。

结果

单因素分析显示女性（

=0.029）、小动脉瘤（

=0.001）、术中动脉瘤破裂（

=0.007）及脑血管痉挛（

0.001）是术后发生DCI的危险因素，而吸烟史（

=0.020）为其保护性因素。多因素Logistic回归分析显示小动脉瘤（

=0.002，

=2.951

95%

：1.478~5.893）、术中动脉瘤破裂（

=0.004，

=7.829

95%

：1.924~31.854）及脑血管痉挛（

0.001，

=5.919

95%

：2.887~12.134）为术后DCI的独立危险因素。

结论

妥善处理小动脉瘤，积极预防术中动脉瘤破裂和治疗脑血管痉挛，可有效防止DCI发生，从而降低致残率，改善患者预后。

Abstract

Objective

To analyze the risk factors and clinical significance of delayed cerebral infarction (DCI) after intracranial aneurysm (IA) clipping.

Methods

A retrospective analysis was performed on the clinical data of IA patients admitted to the First Affiliated Hospital of Chongqing Medical University from January 2015 to December 2019. A total of 480 patients undergoing aneurysm clipping were included. The patients with DCI were set as the observation group (n=42)

and those without as the control group (n=438). The risk factors for DCI were screened by univariate and multivariate logistic regression analysis.

Results

Univariate analysis showed that female (

=0.029)

small aneurysms (

=0.001)

intraoperative aneurysm rupture (IAR) (

=0.007) and cerebral vasospasm (

0.001) were risk factors for DCI after IA clipping

while smoking history (

=0.020) was a protective factor. Multivariate logistic regression analysis indicated that small aneurysms (

=0.002

=2.951

95%

: 1.478~5.893)

IAR (

=0.004

=7.829

95%

: 1.924~31.854) and cerebral vasospasm (

0.001

=5.919

95%

: 2.887~12.134) were postoperative independent risk factors for

DCI.

Conclusion

Proper treatment of small aneurysms

proactive prevention of IAR and treatment of cerebral vasospasm can prevent the occurrence of DCI effectively

and thereby reduce the disability rate and improve the prognosis of patients.
