6 Fig 5 Histology and immunohistochemistry comparing representative sections of normal vein, varicose vein, and venous aneurysm (original magnification ×200) demonstrating attenuation of the venous wall in varicose vein and venous aneurysm. The expression of matrix metalloproteinase (MMP) -2, -9, and -13 is increased in venous aneurysms compared with normal vein and varicose vein. H&E, Hematoxylin and eosin.

7 Fig 6 Western immunoblot demonstrating variable expression of matrix metalloproteinase (MMP) -2, MMP-9, and tissue inhibitor of metalloproteinase (TIMP)-2 in varicose vein (VV), normal saphenous vein (NSV), and venous aneurysm (VA). One specimen in each group demonstrated increased expression of TIMP-2. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

8 Fig 7 Gelatin zymography showing expression of pro-matrix metalloproteinase (MMP)-2 and pro-MMP-9. Pro-MMP-2 was detected in all specimens with variable activity. NSV, Normal saphenous vein; VA, venous aneurysm; VV, varicose vein. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2008 The Society for Vascular Surgery Terms and Conditions
