Abstract:
We describe a 74-year-old male who underwent open stent repair for an infrarenal abdominal aortic aneurysm with a severely calcified aortic neck. The stent graft was constructed by covering a 50-mm long Gianturco Z stent (diameter: 20 mm) with a Dacron prosthesis (diameter: 20 mm). The stented Dacron graft was inserted into the calcified aortic neck, was then sutured to the trimmed aneurysmal wall, and was anastomosed to a bifurcated prosthesis. The distal ends of the bifurcated prosthesis were anastomosed to both common femoral arteries, and the terminal aorta was closed. The patient had an uneventful postoperative course. This procedure may be a feasible and safe way to repair infrarenal abdominal aortic aneurysm with a severely calcified aortic neck.
