摘要:

目的 分析颅内动脉瘤(IA)介入栓塞术后近期预后不良的影响因素,绘制风险预测Nomogram模型并验证其效能。方法 采用回顾性分析,选取2020年6月至2024年6月西电集团医院收治的278例IA介入栓塞术患者,其中男107例,女171例,年龄(57.08±8.94)岁,体重指数(BMI)为(23.11±3.88)kg/m2。根据患者术后1个月预后情况分为预后不良组、预后良好组,比较两组临床资料,采用t检验、χ2检验进行统计学比较,多因素logistic回归分析患者预后不良的影响因素。应用R软件构建风险预测Nomogram模型,绘制受试者工作特征曲线(ROC)和校准曲线分析Nomogram模型对IA介入栓塞术后近期预后不良发生风险的预测效能及校准度。结果 IA介入栓塞术后近期预后不良发生率为23.02%(64/278)。预后不良组年龄大于预后良好组[(63.64±9.52)岁比(55.12±7.31)岁],动脉瘤体纵横比(AR)小于预后良好组(1.63±0.21比2.48±0.39),术前Hunt-Hess分级3~5级、CT Fisher分级3~4级、手术时机>3 d、术后脑梗死占比高于预后良好组[71.88%(46/64)比42.52%(91/214)、67.19%(43/64)比43.93%(94/214)、84.38%(54/64)比57.01%(122/214)、17.19%(11/64)比4.67%(10/214)],差异均有统计学意义(均P<0.05)。年龄大、术前Hunt-Hess分级3~5级、CT Fisher分级3~4级、AR小、手术时机>3 d、术后脑梗死是IA介入栓塞术后近期预后不良的影响因素(比值比=1.223、2.784、2.507、0.402、2.683、2.134,均P<0.05)。基于上述影响因素构建IA介入栓塞术后近期预后不良的风险预测Nomogram模型,该模型预测IA介入栓塞术后近期预后不良的曲线下面积为0.907,95%置信区间为0.846~0.950,预测灵敏度、特异度分别是93.75%(60/64)、80.37%(172/214),且预测概率与实际概率接近,经Hosmer-Lemeshow拟合优度检验显示拟合良好(χ2=1.905,P=0.309)。结论 IA介入栓塞术后近期预后不良的影响因素为年龄大、术前Hunt-Hess分级3~5级、CT Fisher分级3~4级、手术时机>3 d、AR小、术后脑梗死,基于以上影响因素构建的风险预测Nomogram模型对术后近期预后不良具有良好预测价值。

Abstract:

Objective To analyze the influencing factors of short-term poor prognosis of intracranial aneurysm (IA) after interventional embolization, to construct a risk prediction Nomogram model, and to verify its efficacy. Methods The clinical data of 278 patients with IA treated in Xidian Group Hospital from June 2020 to June 2024 were retrospectively analyzed. There were 107 males and 171 females; they were (57.08±8.94) years old; their body mass index (BMI) was (23.11±3.88) kg/m2. They were divided into a poor prognosis group and a good prognosis group according to their prognosis one month after the operation. The clinical data of the two groups were compared by t test and χ2 test. The influencing factors of poor prognosis were analyzed by the multivariate logistic regression. A risk prediction Nomogram model was constructed by the R software. The receiver operating characteristic curve (ROC) and calibration curve were drawn to analyze the predictive efficacy and calibration degree of the model for the risk of short-term poor prognosis after IA interventional embolization. Results The incidence rate of short-term poor prognosis after IA interventional embolization was 23.02% (64/278). Compared with the good prognosis group, the poor prognosis group was older [(63.64±9.52) years vs. (55.12±7.31) years], and had a lower aspect ratio (AR) of aneurysm body (1.63±0.21 vs. 2.48±0.39) and higher proportions of the patients with Hunt-Hess grade 3-5, CT Fisher grade 3-4, operation time >3 d, and postoperative cerebral infarction [71.88% (46/64) vs. 42.52% (91/214), 67.19% (43/64) vs. 43.93% (94/214), 84.38%(54/64) vs. 57.01% (122/214), and 17.19% (11/64) vs. 4.67% (10/214)], with statistical differences (all P<0.05). Older age, preoperative Hunt-Hess grade 3-5, CT Fisher grade 3-4, low AR, operation opportunity >3 d, and postoperative cerebral infarction were the influencing factors of the short-term poor prognosis after IA interventional embolization [ratio ratio (OR)=1.223, 2.784, 2.507, 0.402, 2.683, and 2.134; all P<0.05]. A risk prediction Nomogram model for the short-term poor prognosis after IA interventional embolization was constructed; the area under the curve of this model for predicting the short-term poor prognosis after IA interventional embolization was 0.907 (95%CI 0.846-0.950), and the prediction sensitivity and specificity were 93.75% (60/64) and 80.37% (172/214), respectively. The prediction probability was close to the actual probability, and the Hosmer-Lemeshow goodness-of-fit test showed that it had good fit (χ2=1.905; P=0.309). Conclusions The influencing factors of short-term poor prognosis after IA interventional embolization are old age, preoperative Hunt-Hess grade 3-5, CT Fisher grade 3-4, operation opportunity >3 d, small AR, and postoperative cerebral infarction. The risk prediction Nomogram model based on the above factors has good predictive value for short-term poor prognosis after IA interventional embolization.
