Objectives

The effect of routine internal medicine and stroke rehabilitation treatment was not good. To confirm that ultrasound-guided stellate ganglion block (SGB) can improve cerebral blood flow in patients with stroke, Transcranial Doppler (TCD) and carotid ultrasound were used to monitor the cerebral blood flow parameters of ultrasound-guided SGB in patients with stroke.

Methods

A prospective study of 40 patients with stroke from January 2021 to October 2022 randomly divided into two groups (group SGB: undergoing ultrasound-guided SGB and standard medical procedures, control group: undergoing standard medical procedures) with 20 cases in each was conducted in People's Hospital of Chongqing Liang Jiang New Area. TCD and carotid artery ultrasound were monitored before and after treatment. There were no significant differences in general data on age, gender, disease course, and stroke type between two groups (P>0.05).

Results

After treatment, the bilateral ACA Vm of group SGB was significantly higher, the bilateral internal carotid artery RI and left VA RI were significantly lower than in control group (P<0.05). In group SGB, the Vm of bilateral MCA, bilateral PCA, right ACA, bilateral VA, and BA after treatment were significantly (P<0.05) increased compared to before treatment. PI of bilateral MCA, right ACA, and left VA after treatment were significantly (P<0.05) decreased compared to before treatment. RI of bilateral MCA, bilateral PCA, and bilateral VA after treatment were significantly (P<0.05) decreased compared to before treatment. Right internal carotid artery D after treatment was significantly (P<0.05) higher than before treatment. RI of bilateral internal carotid artery after treatment was significantly (P<0.05) lower than before treatment.

Conclusions

Ultrasound-guided stellate ganglion block could improve local cerebral blood flow and vascular compliance in patients with stroke, and reduce vascular resistance.

超声引导下星状神经节阻滞改善脑卒中患者脑血流的前瞻性研究

目标

常规内科及脑卒中康复治疗效果不佳。为证实超声引导下星状神经节阻滞（SGB）能够改善脑卒中患者脑血流，采用经颅多普勒（TCD）和颈动脉超声监测超声引导下星状神经节阻滞（SGB）脑卒中患者脑血流参数。

方法

人民医院进行了一项前瞻性研究，纳入 2021 年 1 月至 2022 年 10 月 40 例脑卒中患者，随机分为两组（SGB 组：接受超声引导下 SGB 和标准医疗程序，对照组：接受标准医疗程序），每组 20 例。重庆两江新区医院。治疗前后监测TCD和颈动脉超声。两组患者年龄、性别、病程、脑卒中类型等一般资料比较，差异均无统计学意义（P>0.05）。

结果

治疗后，SGB组双侧ACA Vm显着高于对照组，双侧颈内动脉RI及左侧VA RI显着低于对照组（P<0.05）。 SGB组治疗后双侧MCA、双侧PCA、右侧ACA、双侧VA、BA的Vm较治疗前均显着升高（P<0.05）。治疗后双侧MCA、右侧ACA、左侧VA的PI较治疗前均显着下降（P<0.05）。治疗后双侧MCA、双侧PCA、双侧VA的RI较治疗前均显着降低（P<0.05）。治疗后右侧颈内动脉D较治疗前显着升高（P<0.05）。治疗后双侧颈内动脉RI较治疗前显着降低（P<0.05）。

结论

超声引导下星状神经节阻滞可改善脑卒中患者局部脑血流量和血管顺应性，降低血管阻力。
