BACKGROUND
Complex intracranial aneurysms are often treated with endovascular stent-assisted coiling. Intracranial stents are difficult to visualize with conventional computed tomography (CT) or fluoroscopy. "Stent view" flat-detector CT can be used to visualize intracranial stents during endovascular treatment.
METHODS
Three patients underwent endovascular treatment of complex intracranial aneurysms. Stent view flat-detector CT was used to study stent placement and morphology in vivo.
RESULTS
Stent view CT was successful in visualizing stents in all patients. In two patients, stent morphology rendered endovascular coiling technically unfeasible; in one patient, visualization of stent strut herniation into the aneurysm lumen allowed successful coil embolization of the aneurysm.
CONCLUSIONS
Stent view CT provided detailed imaging of stent placement and morphology in all three cases. The technique influenced treatment decisions and technical outcomes. Stent view CT is a valuable intraprocedural technical tool in stent-assisted endovascular procedures.
背景
复杂颅内动脉瘤常采用血管内支架辅助弹簧圈栓塞治疗。颅内支架在常规 CT 或透视下难以显影。“支架视图”平板探测器 CT 可在血管内治疗期间用于可视化颅内支架。
方法
3 名患者接受了复杂颅内动脉瘤的血管内治疗。支架视图平板探测器 CT 用于研究体内支架放置和形态。
结果
支架视图 CT 成功地在所有患者中可视化了支架。在 2 名患者中，支架形态使血管内弹簧圈栓塞技术变得不可行；在 1 名患者中，支架支柱疝入动脉瘤腔的可视化使得动脉瘤的线圈栓塞成功。
结论
支架视图 CT 为所有 3 例患者提供了支架放置和形态的详细成像。该技术影响了治疗决策和技术结果。支架视图 CT 是支架辅助血管内手术中一种有价值的术中技术工具。
