[Experience with implantation of a fenestrated endoprosthesis to a patient with a juxtarenal aortic aneurysm].

In patients with a juxtarenal abdominal aortic aneurysm the unaltered segment is frequently insufficient to secure adequate proximal fixation of the stent graft or is entirely absent, thus making it problematic to exclude the aneurysm from the blood flow by means of classic endoprosthetic repair. For this reason, in order to preserve the blood flow through visceral and renal arteries fenestrated endoprostheses are used as alternative minimally invasive treatment policy. Described herein is the first in the Russian Federation clinical case of using a fenestrated endovascular graft for treatment of a juxtarenal aortic aneurysm. Our patient had high surgical risk due to severe concomitant pathology and was therefore subjected to implantation of a fenestrated endoprosthesis with the preservation of the blood flow through the superior mesenteric artery and both renal arteries. The operation was successful with the complete exclusion of the aneurysm from the blood flow. The first and subsequent controls in the postoperative period showed an adequate position of the endoprosthesis and normal blood flow through the visceral branches.
