      THE INCREASING VALUE OF THE ABERRANT RIGHT SUBCLAVIAN ARTERY DIAGNOSIS (Abstract): The aberrant right subclavian artery (ARSA) is considered a normal variant and most of the patients with this diagnosis have a normal life without any simptoms. It became increasingly popular in the last decade’s medical literature mainly because of its importance during the prenatal diagnosis as a marker for Trisomy 21 (T21). As a T21 marker, it can be detected from the first trimester of pregnancy, but usually it is detected at the time of the second trimester screening scan. Later in life it is essential for confirming Dysphagia lusoria (DL). The patients with ARSA need special precaution during specific investigations and procedures. It can complicate investigations such as gastroscopy or transesophageal echocardiography. It can also lead to life-threatening complications in tracheostomies, upper thoracic surgery of the vertebrae and even in right subclavian vein catheterisation. In patients with this diagnosis early tracheostomy, early gastrostomy or early removal of nasogastric or tracheal intubation are recommended.
