title: [Primary malignant intraluminal tumor of the aorta].
abstract: Primary malignant tumors of the aorta are only rarely reported. We describe here our findings in a 55-year-old patient who was referred to us with progressive renal insufficiency. At angiography, right renal artery occlusion and high-grade stenosis of the left renal artery was found in this patient, who had undergone aortobiliacal reconstruction for acute Leriche syndrome 5 months previously. Histological evaluation of thrombotic material revealed an intraluminal malignant tumor to be the underlying cause. This diagnosis was then confirmed in samples harvested during angiography. CT scan showed an extension beginning 2 cm proximal to the celiac trunk. The patient was treated by thoracoabdominal resection of the aorta, including the paraaortal tissue, left side nephrectomy, and adrenalectomy. A thoracoabdominal aortic prosthesis was inserted up to the iliacal bifurcations and the celiac and superior mesenteric arteries reimplanted. Right nephrectomy followed 3 weeks later. The postoperative course was uneventful.
