title: Technical considerations for transabdominal aortic reconstruction with renal fusion and ectopia: case series.
abstract: Aortic diseases associated with renal anomalies can present special challenges during surgery of the abdominal aorta. The aim of this paper is evaluation of morbidity and definition of optimal management according to the clinical histories of 30 patients with horseshoe and ectopic kidneys who underwent surgical procedures on the abdominal aorta over a 20-year period. Twenty-two of them had horseshoe kidney and eight had ectopic kidney. Indications for surgery included aortic aneurysms in 25 patients and aortoiliac occlusive disease in 5. Preoperative diagnostics were performed in all cases by means of computed tomography and angiography (except in the cases with ruptures) associated with duplex ultrasonography. In patients with ectopic kidney a Carrel patch technique was used for the reimplantation of the renal arteries into the body of the bifurcated (four cases) or tubular (four cases) Dacron graft in five (62.5%) cases whereas aortorenal bypass with Dacron graft was obtained in three cases (37.5%). Sixteen patients from the horseshoe kidney group required renal revascularization (reimplantation using Carrel patch in 10 patients and aortorenal bypass using Dacron graft in 6 patients). Two patients, both with ruptured abdominal aortic aneurysms died after the operation. In other cases the average follow up period was 6.2 years (6 months to 17 years). In one case control, angiography after 6 months revealed an occluded left renal artery that was reimplanted by Carrel patch but without repercussions on the renal function. Aortic surgery in patients with renal anomalies can be safely performed without increased mortality.
