Background:
Non-A non-B aortic dissection remains a complex and controversial pathology. Although open repair remains the gold standard, its invasiveness may limit applicability in high-risk patients.
Case Summary:
We present the case of a 65-year-old woman with non-A non-B dissection and prohibitive surgical risk who underwent successful total endovascular arch repair using a Concave Supra-arch triple-branched stent-graft (CS) system (Lifetech Scientific). The procedure involved precise deployment of the main body, selective catheterization, and bridging stent placement. Follow-up imaging confirmed entry tear exclusion, branch patency, and favorable remodeling without complications.
Discussion:
The CS device features a concave configuration along the greater curvature, with 2 antegrade branches for the innominate and left common carotid arteries and 1 retrograde branch for the left subclavian artery, facilitating stable anatomic reconstruction.
Take-Home Messages:
Total endovascular arch repair with the CS system offers a viable solution for high-risk patients. Routine application warrants caution owing to limited outcomes data.
