Case report: lower limb arterial blood supply arising from the renal artery with congenital absence of the ipsilateral iliac arteries.
A case of a young male who developed left lower limb claudication following left nephrectomy is presented. Investigations, including an exploratory laparotomy, demonstrated the absence of left common and internal iliac arteries. An abnormal left external iliac artery arose from the left renal artery and, with collaterals, formed the arterial supply to the lower limb. This anomalous vascular pattern may have caused the pelvi-ureteric junction obstruction which necessitated the nephrectomy. Division of the renal artery at nephrectomy compromised the circulation to the ipsilateral lower limb. Recognition of this anomaly dictates extra caution when dividing the renal artery at nephrectomy performed through a posterolateral approach.
