A novel percutaneous double-lumen stent graft technique for treatment of chronic type B aortic dissection under local anesthesia

We present a novel endovascular technique for treatment of chronic dissection with abdominal aortic aneurysm whereby multiple overlapping stent grafts are placed in parallel in the true and false lumens in a 65-year-old woman. The use of multiple stent grafts within each lumen allowed total aneurysm exclusion and prevention of false lumen reperfusion while the parallel placement preserved flow in both lower extremities. Postoperative imaging showed complete exclusion of the aneurysm with patency of all aortic branches and no evidence of endoleak. The success of this novel procedure demonstrates feasibility of parallel stent graft implantation in both true and false lumens.
