Renal artery pseudoaneurysm after open partial nephrectomy for renal cell carcinoma.

INTRODUCTION: Renal artery pseudoaneurysm is a well-described complication of open and laparoscopic partial nephrectomy. Delayed bleeding from a renal artery pseudoaneurysm is rare after open partial nephrectomy. CASE DESCRIPTION: Here, we present a 75-year-old man who, 14 days after undergoing an open right partial nephrectomy for an endophytic 4.5 cm tumor, developed painless macroscopic hematuria. Prompt computer tomography angiography imaging, followed by therapeutic angio-embolization of segmental renal artery with coils, treated the pseudoaneurysm successfully. CONCLUSION: Renal artery pseudoaneurysm can be treated rapidly, effectively, and with minimal patient morbidity via percutaneous renal artery embolization.
