Vein occlusion refers to a type of diseases characterized by venous stenosis or occlusion. Its main clinical manifestations include poor distal venous return, swelling, and aching pain. To be specific, lower extremity deep venous thrombosis is relatively common. As soon as the thrombus drops, it can easily give rise to pulmonary embolism and other acute diseases. This chapter introduces the formation of lower extremity deep venous thrombosis as well as clinical manifestations, surgical process, and intraoperative observation points of Budd-Chiari syndrome.
