Aortic compliance in healthy subjects: evaluation of tissue Doppler imaging

Ultrasound in Medicine & Biology
Anne LongMarc Sapoval

Abstract

Increased compliance of abdominal aortic aneurysms at maximum diameter over time might be related to rupture. Compliance could, therefore, be valuable in their management. However, such measurement requires a sophisticated system. An original arterial wall-motion measurement technique, based on tissue Doppler imaging (TDI) and providing segmental exploration, was applied to the study of aorta walls. We report its validation in healthy subjects. Technical feasibility was reliable. The time required for sequence acquisition and transfer was suitable for routine clinical use and the quality of the sequences provided precise identification of the aorta wall/lumen interface and accurate segmentation. The values characterising normal aortic compliance were similar to those previously published, and the initial results concerning reproducibility were appropriate for clinical studies. Further refinements may improve it. This study validates the TDI system for measurement of abdominal aortic compliance in healthy subjects. Study of application to aneurysm compliance is in progress.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
