Abstract
A 59-year-old man was referred to our hospital because of right abdominal pain. He had been maintained on hemodialysis for 10 years and 3 months. Computed tomography (CT) demonstrated bilateral acquired cystic disease of kidney and right retroperitoneal hemorrhage. The patient was treated by transcatheter embolization (TAE) of the right renal artery. On the 13th day after surgery, he had complained of acute right abdominal pain during hemodialysis. CT demonstrated that the right retroperitoneal hemorrhage had enlarged. Right renal arteriography was repeated and it demonstrated that hemorrhage occurred from another renal artery, that had not been detected during the previous TAE. Therefore, we performed the second TAE. The postoperative course was uneventful. Eighteen months after TAE, there has not been any new hemorrhage. This case and the treatment of retroperitoneal hemorrhage are presented with a review of the relevant literature.
