A case of severe iliac artery stenosis treated by stenting without contrast agent

Re-use of contrast agent during endovascular treatment in patients with contrast agent allergy may lead to severe allergic reaction. For patients with localized stenosis of external iliac artery, endovascular therapy (stenting) is the first choice. Whether patients with severe iliac artery stenosis with contrast allergy can be treated with endovascular therapy is unknowed. A case of iliac artery stenting without contrast agent is reported in this paper. The successful implementation of this operation requires adequate preoperative and intraoperative preparation, and the accurate determination of the stenosis site and the presence or absence of residual stenosis during the operation.
