The Importance of Correctly Labelling Ultrasound Images

Abstract

In a recent article in this journal Saad et al described the combined use of interscalene and supraclavicular brachial plexus block for brachioaxillary graft in patients with chronic renal failure. The article included a figure showing the ultrasonic appearance seen during supraclavicular brachial plexus block (Figure 1A). I wish to draw attention to the incorrect labelling of the pleura in that image. The pleura is an important structure to identify and avoid with the needle when performing a supraclavicular block and a clear understanding of the relevant ultrasound anatomy is vital.
