✦ Synopsis

Purpose. To obtain more detailed information about the dynamic mechanical properties of human arteries in vivo, using a new technique based on intravascular ultrasound (IVUS). Methods. Arterial compliance was measured in the common and/or external iliac arteries of 6 patients using an IVUS device, concurrently obtained intraarterial pressure measurements, and a video motion analysis system.

Results. Compliance decreased with increasing vessel diameter and mean arterial pressure. Pre-and postangioptasty measurements were obtained in 2 patients but did not demonstrate a consistent change in compliance following angioplasty. Conclusion. We conclude that IVUS provides an accurate means for in vivo determination of human arterial compliance, the practical value of which needs to be established.
