Arterial wall mechanical characteristics after treatment in collagenase: an in vitro aneurysm model
Fig. 4: Light photomicrograph of the arterial wall after a 6-hour incubation in buffered collagenase. All 3 segments (descending thoracic aorta [A], suprarenal artery [B] and infrarenal artery [C]) showed a significant reduction in wall thickness. The luminal and adventitial layers were completely removed in all segments. The remaining arterial structure was the elastic network of the media. Original magnification: 300 ×.
