We evaluated the feasibility of angiographic computed tomography (ACT) for visualizing stent material in patients who underwent intracranial or extracranial stent placement to treat atherosclerotic lesions or stent assisted coil embolization.
We performed intrarterial and intravenous ACT on biplane angiography system equipped with flat panel detectors (Axiom Arits dBA; Siemens Medical Solutions, Forchheim, Germany). Vistipaque 320 was injected for contrast medium, total 150 mL at flow rate of 5 mL/s through artery and 77 mL at flow rate of 3.5 mL/s through vein.
ACT is a new imaging modality that provides a clear visualization of stent strut.
Therefore this new application has potential to become the noninvasive option for follow-up after endovascular surgery using stents.
我们评估了血管造影计算机断层扫描（ACT）在可视化接受颅内或颅外支架置入以治疗动脉粥样硬化病变或支架辅助弹簧圈栓塞患者的支架材料方面的可行性。
我们在配备平板探测器的双平面血管造影系统（Axiom Arits dBA；西门子医疗解决方案公司，德国福希海姆）上进行了动脉内和静脉内ACT。注射威视派克320作为造影剂，通过动脉以5 mL/s的流速共注射150 mL，通过静脉以3.5 mL/s的流速注射77 mL。
ACT是一种新的成像方式，可清晰显示支架支柱。
因此，这种新应用有可能成为使用支架的血管内手术后随访的无创选择。
