Arterial pseudoaneurysms can develop secondary to a vessel injury, for example, an arterial line installation. We present a case of an 18-year-old female with mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes syndrome who developed left radial artery and right brachial artery pseudoaneurysms secondary to arterial line placement and repeated blood draws, respectively. The ultrasonographic features of pulsating mass in connection with an artery and the yin-yang sign, combined with the patient's history, allowed accurate diagnosis. She was referred to vascular surgery for definitive treatment.
动脉假性动脉瘤可继发于血管损伤，例如动脉置管。我们报告一例18岁女性线粒体脑病、乳酸性酸中毒和卒中样发作综合征患者，分别继发于动脉置管和反复抽血后，出现左桡动脉和右肱动脉假性动脉瘤。与动脉相连的搏动性肿块的超声特征及阴阳征，结合患者病史，得以准确诊断。她被转诊至血管外科接受确定性治疗。
