Study of Ultrasound-Guided Neck Joint Injections Checking for Unintended Intravascular Injection Using Fluoroscopy

What this Trial Is About

This research aims to evaluate the frequency of unintentional injection of freezing liquid into blood vessels during ultrasound-guided cervical medial branch blocks CMBB. CMBBs are used to diagnose and manage facet-related neck pain, a common cause of axial neck pain and cervicogenic headaches. The study investigates whether ultrasound guidance reduces the risk of vascular injections compared to traditional fluoroscopy methods, using digital subtraction angiography DSA as the standard for detection. Participants will undergo ultrasound-guided cervical medial branch blocks while researchers use fluoroscopy and DSA to monitor needle placement and detect any vascular uptake. The study focuses on the incidence of vascular uptake, observed blood vessels, vascular breaches, number of needle repositionings, and any complications during the block procedure. These procedures are part of the patients usual care. During the study, participants will receive their CMBB with ultrasound guidance while being closely monitored with imaging techniques. Researchers will evaluate the incidence of vascular uptake throughout needle placement and record any complications. The total participation involves observation during the block procedure, aimed at confirming the safety and accuracy of ultrasound guidance in this context.
