Stent placement is commonly used to treat aortic coarctation. Although invasive angiography remains the gold standard, follow-up is often performed using computed tomography, which allows rapid, noninvasive assessment of the aorta and surrounding tissues. The goal of this pictorial essay is to provide a guide to the interpretation of these examinations. Normal and abnormal computed tomographic appearance of different stent types is shown along with reconstructions that can help assess stent integrity and the stent position in relation to the aortic wall and branches. Furthermore, imaging findings of complications including aortic wall injuries, restenosis, and intimal hyperplasia are depicted.
支架置入术常用于治疗主动脉缩窄。虽然有创血管造影仍是金标准，但通常使用计算机断层扫描进行随访，这可快速、无创地评估主动脉及其周围组织。本影像学专题文章旨在提供解读这些检查的指南。本文展示了不同支架类型的正常和异常 CT 表现，以及有助于评估支架完整性和支架相对于主动脉壁和分支位置的重建。此外，还描述了包括主动脉壁损伤、再狭窄和内膜增生在内的并发症的影像学发现。
