Vasovagal Rates in Flouroscopically Guided Interventional Procedures: A Study of Over 8,000 Injections

Abstract

vv reactions have an overall low occurrence rate (2.6%) in interventional procedures ranging from 0% in peripheral knee and shoulder injections to 5.1% in medial branch blocks. Conservative treatment of vv reaction and willingness to terminate procedures resulted in no serious adverse events related to vv reaction in 8,010 procedures.
