Leg thrombosis, divided into arterial thrombosis of the legs and venous thrombosis of the legs. Leg thrombosis, is a common disease in vascular surgery. When a thrombosis in the leg is suspected, it is recommended to visit a specialized vascular surgery clinic to improve ultrasound examination, clarify the diagnosis and stage of thrombosis, and give appropriate treatment under the guidance of a specialized vascular surgeon. While some hospitals do not have their own specialized vascular surgery department, they can also go to general surgery department for a clear diagnosis. In recent years, with the development of endoluminal technology, the interventional departments of some hospitals also carry out the diagnosis and treatment of vascular diseases in the legs. Therefore, when a thrombosis in the leg is suspected, you can visit the vascular surgery department, general surgery department or interventional department of the hospital and get a clear diagnosis under the guidance of a specialist to assist in further treatment. At present, the treatment of leg thrombosis is mainly based on the nature of thrombosis, such as the treatment of venous thrombosis is mainly based on anticoagulation and promotion of reflux treatment, and the treatment of arterial thrombosis is mainly based on antiplatelet therapy. And after the development of endoluminal technology, the treatment of vascular thrombosis has also been significantly improved and effective with the help of endoluminal.
