title: Ultrasound-guided trans-hepatic embolization of a renal artery pseudoaneurysm in a patient with acquired solitary kidney and with chronic renal failure secondary to phenacetin abuse.
abstract: A patient with a pseudoaneurysm of the right renal artery underwent treatment with percutaneous approach. No complications were observed. Based on the experience described in this report, a percutaneous ultrasound guided approach can be proposed in selected patients. Renal insufficiency and allergic reactions are potential contraindications to angiography with conventional ionic iodinated contrast dye in patients who need endovascular stent-graft placement. Real-time contrast-enhanced ultrasound (CEUS) guided endovascular procedures may provide an alternative to overcome these limitations. We report an endovascular renal artery repair in a solitary kidney patient with an asymptomatic infrarenal aortic aneurysm and renal insufficiency due to phenacetin abuse. The precise placement of the stent-graft was performed with CEUS and intraprocedural angiographic fluoroscopy without the use of any nephrotoxic contrast dye. During follow-up, CEUS was used to exclude endoleaks, stent-graft failure or malposition.
