title: False Lumen Embolization to Treat Disseminated Intravascular Coagulation After Thoracic Endovascular Aortic Repair of Type B Aortic Dissection.
abstract: OBJECTIVE
  To present a rare case of disseminated intravascular coagulation (DIC) after thoracic endovascular aortic repair (TEVAR) and its novel treatment.
  
  
  METHODS
  A 55-year-old man presented with DIC 10 months after TEVAR for chronic type B aortic dissection and descending thoracic aortic aneurysm. He had persistent retrograde flow in the false lumen with a stable aneurysm diameter. The false lumen was embolized with multiple Amplatzer plugs, which promoted false lumen thrombosis. Laboratory evaluation on postoperative day 7 demonstrated resolution of the coagulopathy. Follow-up at 18 months revealed no recurrent DIC; computed tomography angiography showed a stable aortic diameter and excluded thoracic aneurysm sac.
  
  
  CONCLUSIONS
  This case demonstrates an unusual, potentially fatal postoperative complication of endovascular treatment of type B aortic dissections successfully treated with an innovative endovascular solution.
