Radial artery pseudoaneurysms are rare, and those that become infected are rarer still. We present the case of a patient who developed a radial artery pseudoaneurysm as a late complication of arterial catheterization. Blood cultures were positive for Staphylococcus aureus, and a pulsatile mass, with associated tissue necrosis, was palpable over the radial artery. The diagnosis was confirmed by gray-scale and color Doppler sonography, which showed a partially thrombosed pseudoaneurysm and turbulent flow in the pseudoaneurysm and native artery.
桡动脉假性动脉瘤较为罕见，而发生感染的则更为罕见。我们报告一例患者，其桡动脉假性动脉瘤是动脉插管的晚期并发症。血培养显示金黄色葡萄球菌阳性，在桡动脉处可触及搏动性肿块，并伴有组织坏死。灰阶和彩色多普勒超声检查确诊了该诊断，显示为部分血栓形成的假性动脉瘤，且假性动脉瘤和原动脉内有湍流。
