Aberrant microchip migration has been reported in domestic animal species, but in most cases, this migration is atraumatic to the patient. Reports of microchip-associated trauma and sarcoma development also have been reported in a variety of mammal species. This report describes accidental arterial microchip insertion causing obstruction of the iliac artery in a Chilean flamingo (Phoenicopterus chilensis). Diagnostic imaging included digital radiography and pre- and post-contrast computed tomography to determine the location of the microchip. Surgical removal of the microchip was attempted; however, the flamingo died intraoperatively. Postmortem evaluation found trauma to the epicardium, without penetration of the ventricle. The descending aorta was found traumatized and identified as the most likely insertion point leading to the embolism.
在家畜物种中已报道过微芯片异常迁移的情况，但在大多数情况下，这种迁移对动物并无创伤。在多种哺乳动物物种中也有微芯片相关创伤和肉瘤形成的报道。本报告描述了一只智利火烈鸟（Phoenicopterus chilensis）意外动脉内插入微芯片导致髂动脉阻塞的情况。诊断性成像包括数字X线摄影以及对比增强前后的计算机断层扫描，以确定微芯片的位置。尝试通过手术取出微芯片；然而，这只火烈鸟在手术过程中死亡。尸检评估发现心外膜有创伤，但未穿透心室。降主动脉发现有创伤，并被确定为导致栓塞的最可能插入点。
