SIVAK, Leonardo; EISELE, Guillermo; VARGAS, Oscar  and  MANOSALVA, Harvey. Hematuria in polycystic kidney disease: successful treatment using superselective artery embolization. Rev. nefrol. dial. transpl. [online]. 2014, vol.34, n.3, pp.155-158. ISSN 2346-8548.

A patient of 81 years old, with oversized polycystic kidneys, chronic kidney disease in stage 3, and a bleeding right polar cyst, that caused severe anemia, is presented. First, a nephroprotective protocol was applied. Then, the right renal artery was catheterized, accessing the polar lower branch of the retro-pyelic artery and angiographically identified the bleeding area, and the superselective arterial embolization was performed with fragments of Spongostan. When the procedure concluded, the stopping of the bleeding was proved after two hours. The urinary sediment examination after ninety days of monitoring showed between 6 and 10 red cells per field. The function of the vascular network in polycystic disease, the cell expansion in the cyst wall, and the induced ischemia through the ultraselective interventionist treatment, is discussed in order to preserve kidney function and prevent any complications.
