“…While supraclavicular US-guided FNAB does not contribute much to staging in patients with stage IV, it seems valuable in terms of being a simple and less invasive method for diagnosis [14]. US-guided FNAB may rarely lead to some complications such as hemorrhage, infection, pneumothorax, lymph channel damage, air embolism, phrenic nerve damage, and recurrent laryngeal nerve damage [12,17,18]. No complications have been observed in studies involving US-guided FNAB of the supraclavicular region, suggesting US-guided FNAB as a safe method [5,11,13,19].…”
