CASTILLO C, OCTAVIO et al. Renal artery pseudo aneurism after partial nephrectomy: Report of one case successfully treated with selective embolization. Rev Chil Cir [online]. 2006, vol.58, n.5, pp. 382-385. ISSN 0718-4026. http://dx.doi.org/10.4067/S0718-40262006000500013.
Renal artery pseudo aneurism is an uncommon, severe and difficult to diagnose complication of partial nephrectomy. We report a 72 years old male subjected to a partial left nephrectomy to excise a 6 cm. diameter tumor. The patient was discharged four days after surgery, but was admitted again due to persistent hematuria. An ultrasound showed a cystic lesion in the kidney and clots in the ureter. A selective renal angiography showed a 4 cm diameter pseudo aneurism of the renal artery and a high flow arteriovenous fistula. Afferent branches were embolized and the fistula was completely occluded. A double catheter was installed in the ureter to resolve a hydronephrosis and the patient was discharged without symptoms, four days after admission
