Placement of stent grafts with different calibers into the true and false lumens of anastomotic aneurysms after descending aortic replacement for aortic dissection

Abstract

Abstract Anastomotic aneurysms present as a life-threatening emergency after descending aortic replacement for aortic dissection. Thoracic endovascular aneurysm repair (TEVAR) has been performed since the early 2000s for complicated cases in which re-thoracotomy cannot be adopted. We report the case of a 57-year-old male patient, during a 5-year follow-up after descending aortic replacement for aortic dissection, developed aneurysm expansion around the false lumen on the peripheral side of the artificial graft. Considering the risk and the patient’s desires, we opted to perform TEVAR with different calibers into the true and false lumens “modified kissing stents technique”. His postoperative course was uneventful without any complications. This case highlights the utility of the modified kissing stents technique for anastomotic aneurysms after descending aortic replacement for aortic dissection using stent grafts with different calibers into the true and false lumens.
