Figure 5: Thickened tunica media in the caudal ventral artery compared with the common carotid artery.
From: Pitfalls of invasive blood pressure monitoring using the caudal ventral artery in rats
(a,b) Histological sections of the common carotid artery (CCA) from a rat stained with haematoxylin and eosin (a) and Elastica van Gieson stain (b). (c,d) Histological sections of the caudal ventral artery (CVA) from a rat stained with haematoxylin and eosin (c) and Elastica van Gieson stain (d). The tunica media was considerably thicker in the CVA than in the CCA. Scale bar = 200 μm. (e) Comparison of the tunica media area ratio between the CCA and CVA. The tunica media area ratio in the CCA was significantly larger than in the CVA (29.84 ± 2.18% vs. 73.55 ± 5.27%, respectively, P = 0.0001). CCA: common carotid artery, CVA: caudal ventral artery.
