Varicose veins are those veins which have lost their valve tonicity and elasticity and no longer control one-way blood flowing in the body. Normally, veins have one-way valves that prevent your blood from back flowing toward the heart. After losing their tonicity, these valves don’t work efficiently and blood starts to accumulate in the superficial vein instead of going to the heart which results in elongation and dilation of veins, approximately 2-3 times their normal diameter, and following an irregular tortuous course under the skin to accommodate their long length. Due to the loss of their elasticity and tonicity, veins become weak and are more prone to rupture. Also, due to poor venous drainage, the superficial vessels get engorged with blood which results in decreased blood perfusion and peripheral local ischemia occurs. In the case of buffalo, the incidence of varicose veins is low and mostly lower hind limbs veins, like saphenous veins, are involved. Some other veins like radial, cephalic, mammary and coccygeal are also affected in the case of ruminants.
