Single-stage endovascular management of complicated thoracic aorta coarctation concurrent with aortic arch aneurysm using a novel fenestration device.

To present a case with aorta coarctation complicated by aortic arch aneurysm which is clinical rare and entails a high risk of rupture. Here we reported a 46-year-old female patient diagnosed with aortic arch aneurysm combined with coarctation. The computed tomography angiography shows that an irregular aneurysm was located at the aortic arch site with its maximal diameter 86.55 mm and the right end of aneurysm was located 10 mm away from the ostium of left common carotid artery (LCCA). The aneurysm body invaded the left subclavian artery, and at the distal end of aneurysm a coarctation had been observed with a minimum diameter reaching 2.7 mm. We performed percutaneous balloon angioplasty, thoracic endovascular aortic repair to exclude the aneurysm, and simultaneously used a novel in situ fenestration device (Quick-Fenestrater) to revascularize the covered LCCA. This is first case of using a novel fenestration device single-stage endovascular treatment of complicated thoracic aorta coarctation concurrent with aortic arch aneurysm. Combined endovascular techniques can elevate the success rate of reconstruct complicated aorta aneurysm concurrent with coarctation and reduce complications. Under the guidance of Quick-Fenestrater, in situ fenestration could be performed with safety and a high success frequency.
