In communicating aortic dissection, if only the entry or reentry is closed, residual blood flow may cause enlargement of the false lumen. In this case, surgeons were unable to occlude the entry with a stent graft due to the strong flexion of the bilateral common iliac arteries, so they closed only the reentry in the hope that blood flow from the reentry would be high. Unfortunately, due to the high blood flow from the entry, the false lumen was enlarged. But the use of transesophageal echocardiography and epiaortic ultrasound contributed to its diagnosis.
