Percutaneous vaso-occlusion for nonmalignant renal lesions.
Transarterial renal embolization has been used in the management of renal cancer. We report on 9 patients who underwent selective and superselective renal arterial embolization for nonmalignant renal lesions. Embolization was done in 5 patients for hemorrhage owing to renal angiomas, renal artery, pseudoaneurysm, percutaneous renal biopsy and adult polycystic kidney disease, and in 2 patients with end stage renal disease because of massive proteinuria. Another chronic renal failure patient with severe hypertension was treated successfully with bilateral renal embolization. A postoperative renal arteriovenous fistula was treated successfully by catheter vaso-occlusion. Renal embolization may be a suitable alternative to surgery in poor operative risk patients and for technically difficult benign lesions. Renal infection is a contraindication to embolization.
