Ultrasonographic features of vascular closure devices: initial and 6-month follow-up results

<sec><title>Purpose:</title> <p>This study aimed to evaluate the ultrasonographic findings for various types of vascular closure devices (VCDs) immediately after the angiographic procedure and at 6-month follow-up.</p></sec> <sec><title>Methods:</title> <p>We included 18 VCDs including Angio-Seal (n=4), FemoSeal (n=8), ExoSeal (n=3), Perclose (n=2), and StarClose (n=1) in this study. Four patients were implanted with 2 VCDs at the each side of bilateral femoral arteries, while the remaining 8 patients were inserted 1 VCD at the right femoral artery. Ultrasonography was performed within 10 days and at approximately 6 months after the angiographic procedure. Ultrasonographic morphology of the attached VCD and its relationship with the arterial wall were analyzed.</p></sec> <sec><title>Results:</title> <p>Initial ultrasonography revealed the attached VCD as the relevant unique structure with successful deployment and hemostasis. Follow-up ultrasonography demonstrated partial absorption of hemostatic materials in cases of Angio-Seal (n=3), FemoSeal (n=5), and ExoSeal (n=3), changes in the soft tissue surrounding the femoral artery in case of Angio-Seal (n=1), arterial intimal hyperplasia in cases of FemoSeal (n=3), and no gross changes as compared with the initial ultrasonographic findings in cases of Perclose (n=2) and StarClose (n=1).</p></sec> <sec><title>Conclusion:</title> <p>Initial ultrasonographic evaluation reflected the unique structure of each VCD, with most of them being easily distinguishable. Follow-up ultrasonography revealed various changes in the affected vessels.</p></sec>
