On (b)(6) 2015, the patient underwent endovascular repair of a distal aortic arch aneurysm using a non-gore endoprosthesis.Intra-procedure imaging revealed a proximal type i endoleak so that the patient was additionally implanted with a conformable gore tag thoracic endoprosthesis and a touch-up ballooning was performed using a gore tri-lobe balloon catheter (bcl2645j/13902769).A final angiography revealed that the endoleak still remained, but the procedure was concluded with a wait-and-watch approach taken to the endoleak.On (b)(6) 2015, a follow-up computed tomography (ct) did not reveal problems to the patient.On (b)(6) 2016, the patient admitted to the hospital with chest pain.A ct revealed a retrograde type a aortic dissection from the proximal end of the ctag device.The ascending aorta and aortic arch were replaced with a surgical graft to treat the retrograde aortic dissection.Reportedly, it was unknown when the retrograde aortic dissection occurred.The proximal edge of the endoprosthesis or touch-up ballooning may have caused the aortic dissection, but the exact cause was unknown.Later, the patient was discharged of the hospital.
