Abstract
A case is reported of acute renal failure occurring after prolonged abdominal aortic bypass surgery in an overweight 69-year-old male patient. Preoperative serum creatinine concentration was normal. Surgery lasted for 6 h, and infrarenal aortic cross-clamping 2 1/2 h. The patient complained of important lumbar pain immediately after the operation. In the same time, oliguria and acute renal failure also developped (creatinine: 464 μmol·l −1; urea: 13 mmol·l −1). Rhabdomyolysis caused by the kidney-bridge was confirmed by the elevated blood creatine phosphokinase levels (16 000 IU·l −1 on the second postoperative day). A 99m-Technetium methylene-diphosphonate imaging on the 10th postoperative day exhibited diffuse fixation in the paravertebral lumbar and thoracic muscles, extending from Th8 to L3. The acute renal failure regressed completely after haemodialysis.
