title: Massive hemorrhage from a lumbar artery following percutaneous renal biopsy.
abstract: We report a case of severe lumbar artery bleeding following percutaneous renal biopsy. A 68-year-old man with a history of rheumatoid arthritis, gold therapy, and Staphylococcus aureus bacteremia underwent a percutaneous renal biopsy to evaluate nephrotic syndrome and renal insufficiency. Following the procedure, he developed signs of severe hemorrhage. A selective renal angiogram revealed an intrarenal bleeding site that was occluded by selective embolization. The patient failed to stabilize however, and repeat angiography was performed two days later. A lumbar artery was identified as a second bleeding site, and was also occluded by selective embolization. The bleeding was controlled, but the patient developed serious complications and died five days later.
