Posterior tibial artery pseudoaneurysms are rare and can occur in the setting of trauma. Endovascular treatment of post-traumatic pseudoaneurysms has become a viable less-invasive method particularly in young patients in whom the presence of collaterals guarantees distal vascularization. We report an unusual case of a 16-year- old patient who sustained blunt trauma to his right lower extremity due to a bicycle injury and developed a delayed symptomatic pseudoaneurysm of the posterior tibial artery in the absence of tibia fracture. Superselective endovascular treatment with Ethylene Vinyl Alcohol Copolymer based liquid embolic system (Menox) was successfully performed, achieving exclusion of the pseudoaneurysm with preservation of the remaining vascularization of the lower limb.
胫后动脉假性动脉瘤较为罕见，可发生于创伤情况下。创伤后假性动脉瘤的血管内治疗已成为一种可行的微创方法，尤其对于年轻患者，其侧支循环的存在可保证远端血管化。我们报告一例不寻常的病例，一名16岁患者因自行车损伤导致右下肢钝性创伤，在没有胫骨骨折的情况下发生了延迟性有症状的胫后动脉假性动脉瘤。使用基于乙烯-乙烯醇共聚物的液体栓塞系统（Menox）成功进行了超选择性血管内治疗，实现了假性动脉瘤的排除，同时保留了下肢其余的血管化。
