Decompression Technique Using Subcutaneous Angiocatheter Insertion to Relieve Extensive Subcutaneous Emphysema: A Case Report

Background: Trauma, pneumothorax, com-plication of surgery, infection, or malignancy can cause subcutaneous emphysema and although most subcutaneous emphysema cases are self-limited, extensive subcutaneous emphysema can lead to a compromised airway and cardio-vascular system. In this report, we described a successful treatment strategy in which subcutaneous angiocatheter in-sertion was used to relieve the pressure of extensive subcuta-neous emphysema. Case Report: An 83-year-old man was received at the emergency department (ED) for recurrent pneumothorax and extensive subcutaneous emphysema. Six 18-gauge angiocatheters were inserted under the thoracic subcutaneous tissue and a noticeable improvement was seen 3 h after angiocatheter insertion. Why Should an Emergency Physician Be Aware of This?: Subcutaneous angiocatheter insertion may be a safe and uncomplicated decompression technique to relieve extensive subcutaneous emphysema, particularly in the ED.(c) 2023 Elsevier Inc.
