Surgical treatment of abdominal aortic aneurysms associated with horseshoe kidney.
Abdominal aortic aneurysm surgery associated with a horseshoe kidney (HSK) is a serious technical challenge for the surgeon. We reviewed our experience with 127 patients electively operated on between 1990 and 2004 for abdominal aortic aneurysm. Pre- and perioperative medical, surgical, and radiologic data were retrospectively reviewed. Preoperative diagnosis was achieved with computed tomography with or without angiography or with additional conventional aortography. Seven patients were recognized to have had a HSK, with a mean age of 67.29 +/- 2.43 years. Preoperative serum creatinine levels were similar in patients with or without HSK (1.0 +/- 0.08 vs 0.9 +/- 0.12 mg/dL; not significant). In five of the patients with HSK, reimplantation of the anomalous renal artery was necessary. In all 127 patients, hospital mortality consisted of 5 patients, none of whom had an HSK. Dealing with HSK seemed to increase aortic clamp times (30.43 +/- 3.55 vs 27.04 +/- 3.92 minutes; p < .05) slightly. Patients with or without HSK were given similar amounts of intravenous fluid replacement (2,214.2 +/- 441.3 vs 1,923.3 +/- 433.6 mL/patient; not significant) and allogeneic blood transfusion (0.71 +/- 0.49 vs 0.9 +/- 0.4 U/patient; not significant) and had a similar intensive care unit stay. Abdominal aortic aneurysms associated with HSK have been managed without division of the isthmic tissue. The left retroperitoneal approach provided adequate exposure for all patients with HSK.
