[Successful Resuscitation from Cardiac Arrest due to Pulmonary Artery Rupture Utilizing Cardiopulmonary Bypass].

We report a case of successful resuscitation from cardiac arrest due to pulmonary artery rupture utilizing cardiopulmonary bypass. A 79-year-old man was diagnosed with lung cancer; segment resection of the upper lung was scheduled under general anesthesia. Anesthesia was induced uneventfully and surgery began in the right lateral position. During lung resection, the pulmonary artery was ruptured and led to cardiac arrest with pulseless electrical activity. Astriction, volume overload, and hypertensive medication led to vital sign recovery. Percutaneous cardiopulmonary support was achieved with improvements in the blood flow of the femoral vein and artery. Yet, bleeding from the ruptured artery did not stop. Cardiopulmonary bypass with pulmonary artery blood removal and femoral artery blood transmission stopped the bleeding of the damaged part, leading to the repair of the artery. Rapid establishment of cardiopulmonary bypass may be useful in cases of pulmonary artery damage.
