title: Search for the azygos: a lesson learnt from a case with left superior vena cava, esophageal atresia and tracheo-esophageal fistula.
abstract: The azygos vein is of superior importance during the operation for esophageal atresia with tracheo-esophageal fistula (EA; TEF). Its location helps the surgeon to locate the fistula. Newborns with persistent left superior vena cava (LSVC) may have alterations in the location of the azygos, and since LSVC is not uncommon in EAs with fistulae, it is important to locate the azygos during a pre-operative echocardiogram. Foreknowledge of a possible absent azygos may avoid morbidity while trying to locate the fistula. We present a case of a newborn with EA, TEF, and LSVC in which the azygos vein was absent.
