Endovascular treatment of acute type B dissection complicating graft-bypass repair for aortic coarctation

AbstractObjectivesThe early dissection of the descending aorta after the repair of aortic coarctation is very rare. Herein, we present a special endovascular technique used for acute type B dissection complicating graft bypass for aortic coarctation.MethodsThe 48 year-old male patient with the diagnosis of adult type aortic coarctation had bypass procedure between the aortic arch and the descending aorta. Six weeks after the first operation, the patient was readmitted with severe back pain and had the diagnosis of acute type B dissection which involved the descending aorta at the distal part of the graft anastomosis.ResultsTwo separate stent-grafts were deployed respectively 31 × 150 mm and 34 × 200 mm (C-TAG™ WL Gore&Asc., Flagstaff, AZ, USA). The previous Dacron bypass graft was used as a proximal landing zone for the first stent-graft. The distal landing zone for the second stent was the area between the celiac trunk and superior mesenteric artery. Therefore, the covered stent-graft was implanted to the celiac trunk (Viabahn™ 7 × 50 mm WL Gore&Asc, AZ, USA) to maintain its patency before the deployment of the second graft. The segment of coarctation was closed with a vascular plug (Amplatzer™ vascular plug II) to prevent persistent perfusion of aneurysmal false lumen.ConclusionThe endovascular approach offers multiple less invasive options based on a patient-specific problem
