title: [Two Cases of Emergency Extracorporeal Membrane Oxygenation Support in Children Suffering from Tracheo-innominate Artery Fistula].
abstract: Tracheoinnominate artery fistula (TIF) is a relatively rare life-threating complication of long-term tracheostomy. Two patients with TIF were successfully resuscitated by extracorporeal membrane oxygenation (ECMO) support along with advanced cardiovascular life support. The first patient was a 16-year-old boy undergoing long-term tracheostomy because of cerebral palsy, and the other patient was a previously healthy 11-year-old girl who had undergone primary tracheal tumor resection. In both cases, the onset of TIF was sudden, and the patients were immediately transferred to the operating room for emergency thoracotomy under ongoing cardiopulmonary resuscitation. Innominate artery division was performed under ECMO support. Adequate fluid replacement and hemorrhage control are primary treatment options for resuscitating a patient with TIF. However, hemorrhagic shock in patients with TIF is different from that in other patients, because bleeding into the trachea causes severe respiratory failure and poor oxygenation, which may worsen the resuscitation rate. Thus, ECMO can be used as an option for maintaining oxygenation during cardiopulmonary resuscitation in TIF. Anesthesiologists should pay attention to the increased risk of bleeding due to anticoagulation during ECMO initiation. In conclusion, the results of these cases demonstrate the effectiveness of extracorporeal cardiopulmonary resuscitation in TIF patients.
