Chronic partial occlusion of the deep femoral vein. Methylene blue injection into the deep femoral vein. (a) The isolated main branch of the deep femoral vein before its stricture. (b) The dye surfacing at occlusion side into reticular vein plaques. (c) Normal venules and small veins filling from the deep veins through the microcirculation. (d) Incompetent perforans microprepared following its course. (eg) Reticular vein plaques and spider veins at surfacing of incompetent perforantes (arrows). (hj) Varicous larger veins at occlusion side. Scale bars for (a,b,e,i) 1,000 µm, (c,d,f,g,h,j) 500 µm.
