Matrix metalloproteinases and their tissue inhibitors as indicators of aortic aneurysm and dissection development in extracellular matrix remodeling

Figure 4 A clinical radiologic image (angio-computed tomography) of a current dissection leading to the urgent admission of a patient to the emergency unit at our hospital. A small lesion in the inner layer of the aorta is clearly visible. Penetrating blood spreads into the already damaged medial areas (arrows), resulting in hemorrhage throughout the vascular tube.
