Cone-beam computed tomography (CBCT) is widely used for the technical assessment of standard and complex endovascular aortic interventions. Use of iodinated contrast in CBCT imaging might provide useful additional information; however, this also increases the procedural contrast dose, which may cause renal function deterioration, and the radiation exposure. We describe the technique and feasibility of carbon-dioxide (CO)-enhanced CBCT for the technical assessment of standard and complex endovascular aortic repair. In our experience CO-CBCT had no related adverse events and provided satisfactory imaging quality to assess endograft integrity, vessels patency, and was safely performed in case of severe chronic renal insufficiency.
锥形束计算机断层扫描（CBCT）广泛用于标准和复杂的血管内主动脉介入手术的技术评估。在CBCT成像中使用碘化造影剂可能会提供有用的额外信息；然而，这也会增加术中造影剂剂量，可能导致肾功能恶化以及辐射暴露。我们描述了二氧化碳（CO）增强CBCT用于标准和复杂的血管内主动脉修复技术评估的技术和可行性。根据我们的经验，CO-CBCT没有相关不良事件，并且提供了令人满意的成像质量，可用于评估移植物完整性、血管通畅性，并且在严重慢性肾功能不全的情况下也能安全进行。
