Abstract:
Objective To observe the application value of ultrasound classification of blood vessels at C6 transverse process region during ultrasound-guided cervical sympathetic block(CSB).Methods A total of 42 pain patients were retrospectively enrolled.According to vascular distribution morphology and variation,as well as the minimum vertical distance from carotid artery to C6 transverse process shown by ultrasound,blood vessels at C6 transverse process region was classified into type Ⅰ(standard type),Ⅱ(short arterial spacing type),Ⅲ(puncture path obstruction type)and Ⅳ(vascular variation type in blockade zone).CSB needle insertion strategy was adjusted according to the results of ultrasound classification.The needle tip directly reached the puncture target for type Ⅰ,"fluid push method"was used for type Ⅱ and type Ⅲ,while the needle tip needed to be guided to reach the area between carotid sheath and variant blood vessels in the puncture target area for type Ⅳ.The effectiveness and safety of this method were observed.Results Among 42 cases,type Ⅰ was observed in 18 cases(18/42,42.86%),type Ⅱ was noticed in 3 cases(3/42,7.14%),and type Ⅲ and Ⅳ was detected in 9(9/42,21.43%)and 12(12/42,28.57%)cases,respectively.CSB was successfully performed in all 42 cases,Horner syndrome was successfully induced and relieved spontaneously within 1-2 h.No adverse reactions such as local hematoma,pneumothorax,nor local pain was observed.Conclusion Ultrasound classification of blood vessels at C6 transverse process region during CSB was effective and safe,having certain promotion value.
