Embolization of persistent false lumen through reentry tear in a patient who underwent hemiarch replacement operation due to type A dissection.

We used endovascular techniques to treata 67-year-old male patient who had a persistent false lumen (FL) owing to a remnant tear at the ascending aorta after a hemiarch replacement operation. Attempted insertion of a catheter into the tear site in the ascending aorta failed because of the anatomic difficulty. However, an alternative FL pathway was made to reach the opening site by entering the reentry tract. Complete thrombosis of FL with coils and vascular plug was achieved. The FL channel can be used as an alternative pathway to allow a catheter to reach the tear site of the proximal aorta.
