title: Satisfactory recovery after 45 minutes of resuscitation in acute aortic dissection.
abstract: OBJECTIVE
  To report the satisfactory recovery of a woman with acute aortic dissection who underwent cardiopulmonary resuscitation out of hospital and to show that there are still chances of recovery for patients with prehospital cardiopulmonary arrest even due to acute aortic dissection.
  
  
  METHODS
  Case report.
  
  
  METHODS
  An adult critical care unit of a university hospital.
  
  
  METHODS
  A 71-yr-old woman who had a cardiopulmonary arrest out of hospital. Cardiopulmonary resuscitation was performed before arriving at the emergency room of our hospital.
  
  
  METHODS
  Cardiopulmonary resuscitation, echocardiography, computed tomography, aortography, coronary angiography, ascending aortic graft replacement, and brain hypothermia.
  
  
  RESULTS
  Restoration of spontaneous circulation was gained 45 mins after onset of cardiopulmonary arrest. Echocardiographic and computed tomographic images revealed cardiac tamponade caused by type A acute aortic dissection. Since involuntary movements of the extremities in response to noxious stimulation were observed at 30 mins after restoration of spontaneous circulation, we performed an ascending aortic graft replacement and postoperative mild brain hypothermia. The patient recovered satisfactorily 1 month after the operation.
  
  
  CONCLUSIONS
  The results of this case indicate that there are still chances of recovery for patients with prehospital cardiopulmonary arrest, even due to acute aortic dissection. We propose that an appearance of involuntary movements of the extremities in response to noxious stimulation is one key point that should be considered when deciding whether to perform an emergency operation for this kind of patient.
