Proper assessment of endovascular patency after carotid stent (CS) placement with carotid color-coded duplex sonography (CCCD) can be difficult. We investigated the usefulness of contrast-enhanced (CE) CCCD for post-CS follow-up. CCCD images could not depict the entire bloodstream in overlapped stents and in highly positioned stents. CE-CCCD images, however, did provide anatomic information almost equivalent to that of intra-arterial angiography. CE-CCCD is useful in screening for post-CS restenosis.
使用颈动脉彩色编码双功超声(CCCD)对颈动脉支架(CS)置入术后的血管内通畅情况进行准确评估可能具有挑战性。我们研究了对比增强(CE)CCCD在CS术后随访中的应用价值。CCCD图像无法显示重叠支架和高位支架内的整个血流情况。然而,CE-CCCD图像确实提供了几乎与动脉内血管造影相当的解剖学信息。CE-CCCD在筛查CS术后再狭窄方面很有用。
