Fig. 1 Light micrograph of greater saphenous vein, which contains plate-like deposit of calcium in vein intima (arrowhead). Entire intima of this vein is mildly thickened.

Fig. 2 Light micrographs of remnant thigh saphenous veins from two patients undergoing femorodistal bypasses. Marked difference can be seen between thickness of combined inner media-intimal layer. (Methylene blue and azure II stain; original magnification × 100.)

Fig. 3 Light micrograph of thigh saphenous vein demonstrating intimal spindle-shaped cells (arrowheads). (Methylene blue and azure II stain; original magnification × 250.)

Fig. 4 Transmission electron micrograph of intimal spindle-shaped cell from thigh greater saphenous vein. There are few contractile filaments and numerous secretory granules. (Lead citrate, uranyl acetate stain; original magnification × 750.)

Fig. 5 Light micrograph of section through a vein graft stenosis. Small lumen (star) and excessive intimal layer (I) typify this lesion. (Methylene blue and azure II, original magnification × 10.)

Fig. 6 Electron micrograph of intima of Fig. 5. There are loosely arranged spindle-shaped cells surrounded by amorphous matrix. (Lead citrate, uraynl acetate stain; original magnification × 750.)
