Lumbar artery bleeding as a complication of percutaneous nephrostomy in a patient with coagulopathy

Department of Diagnostic Radiology and Organ Imaging, Prince of Wales Hospital, Chinese University of Hong Kong, Shatin, NT, Hong Kong

A case of severe lumbar artery bleeding as a complication of percutaneous nephrostomy (PCN) is presented. A 70-year-old man with coagulation disorder (factor VIII deficiency) underwent left PCN because of left hydronephrosis and abnormal renal function. The procedure was complicated by a major haemorrhage from the left first lumbar artery into the left posterior pararenal space. This case illustrates bleeding from the lumbar artery in a patient with coagulation disorder resulting in a fatal outcome. CT can provide the diagnosis, while angiography with embolisation is an effective means to control the bleeding. These examinations should be performed as soon as possible.
