Abdominal aortic aneurysm repair in patients with pelvic kidney. Technical considerations and literature review.
Effective methods for performing abdominal aortic aneurysmectomy associated with congenital pelvic kidney are presented. The embryology and surgical anatomy of these lesions are reviewed. Ordinarily, successful aortic reconstruction can be performed with low risk to the pelvic kidney by use of readily available in situ cold perfusion. Two illustrative case reports applying this method are presented. The recently reported technique of double proximal clamping of the aorta was also employed in one case. This technique allows lumbar collaterals within the aneurysm to perfuse the kidney during construction of the proximal aortic anastomosis, thereby minimizing absolute renal ischemic time. Both in situ cold perfusion and double proximal clamping are effective methods for renal preservation that do not rely on complex extraanatomic techniques. A review of the literature with a discussion of the advantages and disadvantages of previously reported methods of renal preservation is presented.
