NCT05925439

Brief Summary

Recently, Park et al. introduced a new technique for performing S1 TFESI using ultrasound. S1 TFESI using ultrasound can be considered to overcome the disadvantages of exposure to radiation. We hypothesized that the frequency of intravascular injection differs depending on the type of needle during S1 TFESI under ultrasound guidance.
