Endovascular repair after stent elephant trunk procedure for extensive thoracic aortic aneurysm

Hybrid surgical-endovascular procedure was conducted in a 46-year-old male with extensive thoracic aortic aneurysm. Ascending aorta and arch replacement combined with stent elephant trunk implantation was performed first. An open stent-graft was implanted into the descending aorta. One month later, endovascular repair was conducted. Postoperative CTA showed total coverage of the descending aorta by stent-grafts and the descending aortic aneurysm was totally thrombo-excluded. Stent elephant trunk may be a better alternative to conventional elephant trunk in hybrid surgical-endovascular approaches in treatment of extensive thoracic aortic aneurysm.
