Pseudoaneurysms of the radial artery are extremely rare. In this article, a radial artery pseudoaneurysm that developed after the intervention for hemodialysis at the antecubital area in a 60-year-old female patient undergoing routine hemodialiysis for chronic renal failure was described. The most important causes of pseudoaneurysms in cardiovascular surgery are catheter applications and new arteriovenous shunts on the forearm. Although rare, the complication of radial artery pseudoaneurysm should be kept in mind in this patient population due to the risk of serious morbidity.
