We report on a case of life-threatening abdominal aorta hemorrhage following percutaneous renal biopsy. A 42-year-old woman with chronic kidney disease stage 2 and microscopic hematuria underwent a percutaneous renal biopsy to evaluate renal insufficiency. One hour following the biopsy procedure, she complained of an abdominal pain and developed signs ofoligemic shock. In despite of 4 blood units transfusion, the patient continued to be in shock. She was transmitted urgently to the operating room without any other examinations (such as abdominal computer tomography) and underwent an emergency laparotomy. A transverse tear in the abdominal aorta was identified as the bleeding site, and after occlusion, the hemorrhage was stopped. The patient gradually recovered and she was discharged in good clinical condition after a few days.
