Does a modified candy-plug technique occlude false lumen backflow and reduce aortic diameter in a patient with aortic dissection?
A custom-modified candy-plug device created from a standard aortic extender successfully occluded false lumen backflow and reduced aortic diameter in a patient with chronic aortic dissection.

May offer an endovascular option for residual false lumen flow after TEVAR; leaves open safety, durability, and generalizability.
Purpose: Aim of this technical note article is to introduce a modified, novel way to custom create a candy-plug (CP) device to endovascularly occlude false lumen. The technique is illustrated by a patient case with significant backflow to false lumen (FL). The patient had already undergone surgical repair of the ascending aorta, aortic arch and subsequent TEVAR procedure down to the ostium of the celiac trunk because of type A aortic dissection, but the descending thoracic aorta continued to dilate due to backflow to the FL from an uncovered tear at the level of the renal arteries.Materials and methods: We modified a Gore Excluder 36-45 mm aortic extender (W. L. Gore & Associates, Inc. Flagstaff, USA) endoprosthesis into a CP device that was subsequently positioned under local anesthesia into the FL of the distal descending thoracic aorta.Results: In 1 month control the backflow to false lumen had ceased and the aorta had decreased in diameter from 69 to 66 mm, FL from 37 to 34 mm, true lumen (TL) remained the same 32 mm. Conclusion: We describe a modified, effective candy-plug technique to occlude retrograde false lumen filling in aortic dissection.

Palm et al. (2022) conducted a case report in Aortic dissection with false lumen backflow (n=1). Modified candy-plug technique was evaluated on False lumen occlusion and aortic diameter. A modified candy-plug technique successfully occluded retrograde false lumen filling in a patient with chronic aortic dissection, reducing the false lumen diameter from 37 to 34 mm at 1 month.
