抄録

Acute aortic occlusion is a catastrophic event requiring early recognition and intervention. The patient was diagnosed type B aortic dissection. He became anuric on the sixth day of illness and the femoral artery pulse was not palpable. Therefore the patient was conveyed to our hospital. During transfer, his blood pressure was suddenly elevated and later he was in cardiopulmonary arrest. After cardiopulmonary resuscitation, the heart resumed beating in several minutes. Acute dynamic obstruction was regarded as a cause of the cardiac arrest. A thoracic endovascular aortic repair was performed urgently. His postoperative period was uneventful and the patient was discharged without problems.
