Endovascular Repair for Kommerell Diverticulum With Type A Aortic Dissection.

Total endovascular repair remains challenging for Kommerell diverticulum with chronic type A aortic dissection. We reported the first total endovascular repair for a Kommerell diverticulum with chronic retrograde type A aortic dissection. We conducted total endovascular repair with a unibody, single-branched, stent-graft combined with the chimney technique for reconstruction of both subclavian arteries. Completion angiography showed complete exclusion of the primary entry tear without endoleak and patency of all stent-grafts, and computed tomographic angiography at follow-up showed significant remodeling of the false lumen. In this case we show that total endovascular repair is feasible and safe in selective patients of this kind.
