Pulsed radiofrequency (PRF) treatment of the dorsal root ganglia (DRG) has recently been used as an important option for postherpetic neuralgia (PHN) patients who do not respond well to drugs. This procedure is commonly guided by computed tomography (CT) or fluoroscopy, but they cannot be performed in real time and are associated with radiation exposure. Ultrasound (US) is a potential alternative option, but no reliable method of US-guided DRG PRF treatment has been reported. ⋯ US-guided transforaminal DRG PRF is a safe and effective method for the treatment of cervical PHN. It is a reliable alternative option to the CT-guided procedure, demonstrating great advantages in reducing radiation exposure and the operation time.

The erector spinae plane block (ESPB) is a less invasive, safer, and technically easier procedure compared to the conventional neuraxial technique. Although the ESPB is a favored and easy technique compared to neuraxial block, there is no study with a large number of patients describing the exact spread level of injected local anesthetics. ⋯ The ESPB 20 mL group showed a more extensive distribution of contrast medium than that of the ESPB 10 mL group. Inadvertent injections into the epidural space, psoas muscle, and intravascular system were observed. Among them, intravascular system injections were found to be the most common (12.9%).
