In vivo determination of human arterial compliance: preliminary investigation of a new technique
Abstract
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 postangioplasty 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.
