Safety and efficacy of transcatheter arterial embolization in autosomal dominant polycystic kidney patients with gross hematuria: Six case reports

Figure 1 51-year-old male patient with autosomal dominant polycystic kidney disease had gross hematuria for 1 wk. He regularly conducts hemodialysis in hospital. The abdominal no-contrast computerized tomography scan showed bilateral enlarged kidneys which were full of cysts of uniform size. Acute hemorrhage was found in the cysts (orange arrow).

Figure 2 Bilateral renal arteriography. A: Bilateral renal arteriography showed bilateral enlarged kidneys and slender branches of renal arteries with contrast-medium leaking indicating acute hemorrhage (orange arrows); B: Bilateral renal arteriography showed bilateral enlarged kidneys with microcoils positioned at the main renal arterials and contrast-medium leaking indicating acute hemorrhage (orange arrows).

Figure 3 Autosomal dominant polycystic kidney disease patients. Bilateral renoarteriography showed that microcoils positioned at the renal arterial branches and no contrast-medium leaking indicating the success of hemostasis (orange arrows). A: Conducted transcatheter renal artery embolization with microspheres of polyvinyl alcohol (diameter, 350 μm-560 μm) in branches of renal arteries and microcoils; B: Conducted transcatheter renal artery embolization with microspheres of polyvinyl alcohol (diameter, 350 μm-560 μm) in branches of renal arteries and microcoils in main renal arteries.
