Symptomatic collapse of a thoracic aorta endoprosthesis.

Abstract

We present the case of a 40-year-old man who underwent aortic endoprosthesis implantation for a traumatic lesion of the thoracic aorta (Gore TAG, 26 x 100 mm, after the instructions for use for a thoracic aorta of 22-24 mm). At 6 months, he came to the emergency room for a hypertensive crisis and acute pulmonary edema. The chest radiograph and thoracoabdominal computed tomographic angiography study showed collapse of the endoprosthesis and a type I proximal leak. A second TAG graft was inserted within the previously collapsed device, and re-expansion was achieved, with resolution of the initial symptoms. At 3 and 6 months, the patient remained asymptomatic, and there were no new findings on computed tomographic angiography.
