Axillofemoral and femorofemoral grafts in 12 patients were examined on 22 occasions with linear-array and digital static scanners with 5-MHz transducers and a 10-MHz high-resolution real-time instrument. Real-time instruments that produce a linear image, particularly high-resolution small-parts units, are the most appropriate to define the incorporation of the prosthesis, its pulsatility, and the nature of the perigraft bed. Early after implantation, these grafts have small perigraft fluid collections in the surgically created tunnels. These collections disappear spontaneously as the graft is incorporated into the tissues. However, discrete and persistent perigraft fluid collections are abnormal. Such collections were noted in five patients. One proved to be abscess and four were seromas. Graft occlusions (four patients) and an anastomotic aneurysm (one patient) were also readily diagnosed on sonography.
使用配备5兆赫换能器的线阵和数字静态扫描仪以及一台10兆赫高分辨率实时仪器，对12例患者的腋股和股股移植物进行了22次检查。能够产生线性图像的实时仪器，尤其是高分辨率小部件设备，最适合用于确定假体的融合情况、其搏动性以及移植物周围床的性质。植入后早期，这些移植物在手术创建的隧道中会有少量移植物周围液体聚集。随着移植物融入组织，这些聚集会自发消失。然而，离散且持续的移植物周围液体聚集是异常的。在5例患者中发现了此类聚集。其中1例被证实为脓肿，4例为血清肿。超声检查也很容易诊断出移植物闭塞（4例患者）和吻合口动脉瘤（1例患者）。
