Venous thrombosis occurs when a person is immobilized so muscles can not contract and return blood back to the heart. This stagnation of blood begins to form small lumps along the walls of the veins.
This initial clot may gradually grow to a partial or complete blockage or blocking the venous blood and thus prevent from returning to the same heart.
