An iatrogenic fistula and consequent pseudoaneurysm developed between the right subclavian artery and right pulmonary artery as a result of misplacement of a hemodialysis access catheter. The patient, who was considered to be at high risk for surgical repair, successfully underwent endovascular treatment that involved insertion of two nitinol stents covered with expanded polytetrafluoroethylene (stent-grafts), one into the right subclavian artery and the other into a right upper lobe pulmonary artery. Multi-detector row computed tomographic angiography played an integral role in the evaluation of the patient's vascular injury and treatment planning.
由于血液透析通路导管放置不当，右锁骨下动脉与右肺动脉之间形成了医源性瘘及随之而来的假性动脉瘤。该患者被认为手术修复风险高，成功接受了血管内治疗，包括将两枚覆盖有膨体聚四氟乙烯的镍钛合金支架（覆膜支架）分别置入右锁骨下动脉和右上叶肺动脉。多排探测器计算机断层血管造影在评估患者血管损伤及治疗规划中发挥了不可或缺的作用。
