Intravascular ultrasound (IVUS) imaging provides useful additional information to X-ray angiography in selected cases of balloon angioplasty and stent placement with complex vascular anatomy and unclear findings at angiography. It facilitates accurate measurements of the vessel dimensions and reveals the extent of the disease for the selection of proper angioplasty balloon size, as well as confirms full expansion and attachment of the stent or stent graft to the arterial wall. Intravascular US imagining contributes useful information for the basis of planning surgical or endovascular therapy of aortic dissection and is valuable for guiding percutaneous fenestration of the dissection flap. This imaging modality facilitates placement of vena cava filter without cavography and/or fluoroscopy in patients with contraindication for iodine contrast media and/or X-ray fluoroscopy. Technical development may further increase utility of IVUS imaging in interventional radiology.
在血管解剖结构复杂且血管造影结果不明确的部分球囊血管成形术和支架置入病例中，血管内超声（IVUS）成像可为X射线血管造影提供有用的额外信息。它有助于准确测量血管尺寸，揭示病变范围以选择合适的血管成形术球囊尺寸，并确认支架或支架移植物在动脉壁上的完全扩张和附着。血管内超声成像为主动脉夹层手术或血管内治疗的规划提供了有用信息，对引导夹层瓣的经皮开窗术也很有价值。这种成像方式有助于在对碘造影剂和/或X射线荧光透视有禁忌证的患者中，在不进行腔静脉造影和/或荧光透视的情况下放置腔静脉滤器。技术发展可能会进一步提高IVUS成像在介入放射学中的效用。
