Case Report: The Patient Needed a Long-term Extracorporeal Circulation after Cardiopulmonary Arrest, But the Subsequent Course Was Good

A 47-year-old man who became cardiopulmonary arrest was performed cardiopulmonary resuscitation when he happened to be in the hospital. He had ventricular fibrillation due to acute myocardial infarction, and needed about 30 minutes to return of spontaneous circulation(ROSC). Since Ventricular fibrillation repeated after that, percutaneous cardiopulmonary support device (PCPS) was started and revascularization was performed on obstructive lesions of the coronary artery. After hospitalization, hypothermia therapy was administered for 2 days. PCPS was discontinued on the 7th hospital day, but due to the lower leg ischemia, rhabdomyolysis occurred to develop acute renal failure. Anuria continued for more than 10 days and it was necessary to continue continuous hemodiafiltration(CHDF). But after that renal function gradually improved. It took time, but the consciousness disorder gradually improved. After removal of PCPS, compartment syndrome due to reperfusion injury occurred in the right lower leg. Therefore paralysis of the right lower leg remained. However, there were no other neurological abnormal findings. He needed a brace of the lower leg for walking, but he discharged at the 72nd hospital day. It took a long time to ROSC, requiring long term PCPS and CHDF. However, after that, it was a good process without leaving aftereffects other than paralysis of the lower leg. We report on this case.
