title: [Subrenal aortic occlusion].
abstract: The juxtarenal aortic occlusion is an infrequent but not exceptional condition determining several problems during the corrective procedure. The incidence of this pathological picture is around 10% of the patients affected by steno-obliterative lesions of the subrenal aorta. The danger of this morbid condition derives mainly from the risks threatening the renal function which sometimes is already endangered before surgical intervention. The operation however implies high additional risks because some surgical procedures require suprarenal aortic clamping and because during the surgical manoeuvres embolization could occur in the lumen of renal arteries. This study analyzes 206 patients who underwent surgical intervention for subrenal aortic occlusion during the last 15 years. 11 patients were operated on in emergency because of lower limbs ischaemia. 4 patients presented a complete thrombosis of an aneurysmatic lesion of the subrenal aorta. The study is aimed at analyzing the renal behaviour in the postoperative period, comparing its functionality with the preoperative parameters. A second aspect which will be considered refers to the type of surgical procedure.
