            fingertip oxygen saturation, and intra-arterial pressure were
            monitored throughout the process. An 8F vascular sheath
            (CORDIS 8F, USA) was inserted into the right femoral
            artery, and a J-guide wire (CORDIS, USA) was introduced.   E               F

            (CORDIS 6F JR4, USA) were placed at the level of the
            renal artery, and bilateral renal artery angiography was
            performed. The left renal artery was located at the upper
            edge of the second lumbar vertebra, and the right renal
            artery was located in the middle of the second lumbar
            vertebra. Both had horizontal openings without stenosis
            in the renal artery. The superior mesenteric artery opened   G            H
