Elastin, collagen, and some mechanical aspects of arterial aneurysms Philip B. Dobrin, MD, PhD Journal of Vascular Surgery Volume 9, Issue 2, Pages 396-398 (February 1989) DOI: 10.1016/0741-5214(89)90075-X Copyright © 1989 Society for Vascular Surgery and the North American Chapter, International Society for Cardiovascular Surgery Terms and Conditions

Fig. 1 Pressure-diameter curves for dog carotid arteries. Treatment with elastase caused dilatation and increasing stiffness but not rupture. Treatment with collagenase caused slight dilatation, decreasing stiffness, and rupture. (From Dobrin et al. Arch Surg 1984;119:405–9.)

Fig. 2 Pressure-diameter curves for human internal iliac arteries. The format was the same as that in Fig. 1. Results show dramatic effects after treatment with collagenase. (From Dobrin et al. Arch Surg 1984;119:405–9.)
