Abstract

Background and Purpose

Hemorrhagic transformation (HT) is a common complication of endovascular thrombectomy (EVT) in patients with acute ischemic stroke (AIS). Our study aims to investigate the clinical and imaging predictors of HT and symptomatic intracranial hemorrhage (sICH) in patients who underwent EVT.

Methods

A retrospective analysis of 118 patients undergoing EVT for acute anterior circulation stroke was performed. Potential clinical and imaging predictors of all patients were collected and multivariate logistic regression was performed. The risk prediction system was constructed according to the multivariate logistic regression results.

Results

The incidence of HT and sICH after EVT were 46.6% and 15.3%, respectively. The multivariate logistic regression results showed that Alberta Stroke Program Early CT Score (ASPECTS) (p = .001, odds ratio [OR] = 0.367, 95% [confidence interval] CI, 0.201-0.670), collateral status (p<.001, OR = 0.117, 95% CI, 0.042-0.325), relative cerebral blood flow (CBF) ratio (p = .025, OR = 0.943, 95% CI, 0.895-0.993), and blood glucose on admission (p = .012, OR = 1.258, 95% CI, 1.053-1.504) were associated with HT. While for sICH, collateral circulation (p = .007, OR = 0.148, 95% CI, 0.037-0.589), ASPECTS (p = .033, OR = 0.510, 95% CI, 0.274-0.946), and blood glucose (p = .005, OR = 1.304, 95% CI, 1.082-1.573) were independent factors. The predictive model for HT after EVT was established, and the sensitivity and specificity of it were 90.9% and 79.4%, respectively, with the area under the curve of 90.0% (84.5%-95.4%).

Conclusion

Collateral status, ASPECTS, relative CBF ratio, and blood glucose on admission were predictors for HT in AIS patients, while collateral status, ASPECTS, and blood glucose on admission were also predictors for sICH. In addition, the established predictive model showed good diagnostic value for prediction of HT after EVT.

血管内血栓切除术后急性缺血性脑卒中出血转化的临床和影像学预测因素。

背景和目的：出血转化（HT）是急性缺血性卒中（AIS）患者血管内血栓切除术（EVT）的常见并发症。我们的研究旨在调查接受 EVT 患者发生 HT 和症状性颅内出血（sICH）的临床和影像学预测因素：方法：我们对118例因急性前循环卒中接受EVT治疗的患者进行了回顾性分析。收集了所有患者的潜在临床和影像学预测因素，并进行了多变量逻辑回归。根据多变量逻辑回归结果构建了风险预测系统：EVT术后HT和sICH的发生率分别为46.6%和15.3%。多变量逻辑回归结果显示，阿尔伯塔省卒中项目早期 CT 评分（ASPECTS）（p = .001，几率比[OR] = 0.367，95% [置信区间] CI，0.201-0.670）、侧支状态（p结论：侧支状态、ASPECTS 评分、多变量逻辑回归结果显示，EVT 后的 HT 和 sICH 发生率分别为 46.6% 和 15.3%：侧支状态、ASPECTS、相对 CBF 比率和入院时的血糖是 AIS 患者发生 HT 的预测因素，而侧支状态、ASPECTS 和入院时的血糖也是发生 sICH 的预测因素。此外，已建立的预测模型对预测 EVT 后的 HT 有很好的诊断价值。
