Key result
In vivo adventitia removal significantly decreased arterial diameter and increased elastic and viscous modulus (P<0.05), impairing buffer and conduit functions, effects not seen in vitro.
Why the study?
Does adventitia removal alter arterial wall mechanical properties and functions in ovine brachiocephalic arteries?
Does adventitia removal alter arterial wall mechanical properties and functions in ovine brachiocephalic arteries?
p-value: p=<0.05
The adventitia plays an active role in regulating arterial wall viscous and elastic properties in vivo, likely via a smooth muscle-dependent mechanism.

Adventitial integrity may matter for arterial function in vivo; hypothesis-generating for vascular procedures pending clinical data.
Fischer et al. (2006) studied this question. Adventitia removal vs. Intact vessels (before adventitia removal) was evaluated on Arterial diameter, elastic and viscous modulus, buffering and conduit functions (p=<0.05). In vivo adventitia removal significantly decreased arterial diameter and increased elastic and viscous modulus (P<0.05), impairing buffer and conduit functions, effects not seen in vitro.
