Abstract:
We experienced a 45-year-old male with ADPKD who developed spontaneous retroperitoneal hemorrhages with hypertension in the right subcapsular renal space without trauma. After his condition worsened with conservative management, he was treated by renal transarterial embolization (TAE). Over the next eight years, he experienced bilateral bleeding at three different sites and underwent repeated endovascular treatment with renal TAE to stop the bleeding. After the fourth occurrence, the patient underwent hemodialysis. Although renal cysts and urinary tract bleeding occur frequently in ADPKD, retroperitoneal hemorrhage is rare; however, TAE is both effective and a good way to preserve renal function.
