title: Novel use of carbon dioxide arteriography in renal artery pseudoaneurysm in patients with poor renal function.
abstract: Renal artery pseudoaneurysm (RAP) is a rare complication of partial nephrectomy, but is usually effectively managed with renal vessel embolisation. We report a particularly challenging case of a patient with chronic kidney disease (CKD) who developed a RAP following a laparoscopic heminephrectomy and was treated using superselective renal vessel coil embolisation with carbon dioxide (CO2) as the primary contrast agent for arteriographic localisation of the RAP and feeder artery. To the best our knowledge we report the first utilisation of CO2 arteriography in the definitive diagnosis and treatment of RAP following heminephrectomy in a patient with severe CKD.
