Clinical observation of endovascular thoracic aortic prosthetics in a patient with distal anastomosis aneurysm of a vascular prosthesis formed "end-to-side" after extraanatomic prosthetics

A clinical observation of successful prosthetics of an aneurysm of distal anastomosis of a vascular prosthesis of the thoracic aorta with a stent graft in a patient 24 years after extraanatomic bypass surgery with an end-to-side anastomosis for aortic coarctation is presented. During a routine examination, an aneurysm of the distal anastomosis of the vascular prosthesis was revealed in the patient. After further examination, thoracic aorta endoprosthesis was performed from vascular prosthesis to native aorta with Ankura 2020B120 stent graft (Lifetech Scientific Co., LTD. Shenzhen, China). Intraoperative results of endoprosthetics were assessed as good. The aneurysm of the distal anastomosis was not contrasted, the patency of the vessels of the aortic arch was preserved. According to the control computed tomography study performed 3 months after the operation, the aneurysm of the distal anastomosis is not contrasted, there is no dislocation of the prosthesis, there are no endolics. The above clinical observation demonstrates the effectiveness and safety of thoracic aortic endoprosthesis from a vascular prosthesis to a native aorta with anastomosis aneurysms of a vascular prosthesis, which allows avoiding complex and traumatic repeated open surgical intervention on the aorta and achieving good immediate and long-term treatment results.
