摘要：A 56-year-old woman with a history of hypertension was admitted to the emergency department due to syncope after repeated episodes of severe back pain lasting 30min. One day earlier, she had a sudden onset of severe back pain without further treatment. Contrast-enhanced computed tomography (CT) on admission showed a triple aortic dissection starting immediately after the origin of the left subelavian artery and extending down to the left iliac artery (Figure A). On the arterial phase, CT showed the blood injection sign: high contrast outflow at the entry tear of the outer false lumen. In addition, mediastinal hematoma around the descending aorta and small left pleural effusion were noted. The patient was transferred to the critical care unit, where beta-blockers and nitrates were given and intra-arterial blood pressure was monitored.
