Comparison of intravascular ultrasound measurements at the sites of balloon dilatations of femoral arteries with measurements of postmortem gross arterial segments at the same sites.
Intravascular ultrasound measurements of arterial cross-sectional area at the site of balloon dilatation are quantitatively accurate and consistent with measurements by digital planimetry. Lumen cross-sectional area determinations are virtually the same and the minor differences in total arterial cross-sectional area are probably related to the dehydration of each specimen, which occurred during the interval between studies. Thus, arterial disruption by balloon angioplasty does not interfere with the quantitative accuracy of intravascular ultrasound measurements.
