FIG 1. Drawings illustrate the method used for creating the experimental dissections.
A, In a canine CCA, a small incision is made in the adventitial layer.
B, The adventitia is dissected from the media by using a thin probe that is passed through the adventitial incision.
C, After the two layers are sufficiently dissected, a longitudinal slitlike or elliptical defect is made in the intima.
D, The adventitial incision is tightly closed.
E, Cross-sectional view of the result.
