RESUMO
Objective: To compare the efficacy and safety of ultrasound-guided stellate ganglion block (UGSGB) through anterior scalenus muscle (ASM) and through internal jugular vein (IJV). Methods: Totally 144 patients with cervicogenic headache were distributed into 2 groups randomly. USSGB was performed through ASM (ASM group, n=72) or through IJV (IJV group, n=72), respectively. The ratio of successful blocks, the appearing time of Honer syndrome and the ratio of adverse reaction were compared between two groups. Results: The successful block ratio was 97.22% (70/72) of ASM group and 98.61%(71/72) of IJV group, while Honer syndrome appearing times was (2.18±0.96)min and (1.96±0.87)min after operation, respectively. There was no significant difference between 2 groups (both P>0.05). The adverse reaction ratio was 19.44%(14/72) of SCM group and 4.17%(3/72) of IJV group (P=0.01). Conclusion: USSGB through ASM approach and USSGB through IJV approach are both safe and efficient. IJV approach has less adverse reaction than SCM approach.
RESUMO
Objective To evaluate the basilar artery hemodynamical changes in cervical rotation and ventral flexion by color Doppler flow imaging(CDFI). Methods Basilar artery blood flow were detected during cervical With cervical right lateral,left lateral rotation and ventral flexion, the detection ratio of basilar artery by ultrasound were 89% ,84% ,81% respectively. There were no difference in statistics between the detction ratio of three kinds during cervical flexion,peak systolic velocity(PSV) and end-diastolic velocity(EDV) decreased apparently during left lateral rotation,which did not change during right lateral rotation. No changing was found with resistant index between the three kinds of cervical position. Conclusions The hemodynamic changing of basilar artery during cervical rotation and flexion could be detected by CDFI accurately,which might be useful in clinical study.
