Blood vessel blockage refers to the presence of blood clots in the blood vessels leading to the blockage of blood vessels, dietary control should be given, oral antithrombotic drugs or intravenous thrombolysis, and if necessary, surgical treatment should be carried out. Blood vessel blockage can lead to tissue necrosis. Strict dietary control should be given to reduce the intake of high-fat foods, limit salt and eat more green and fresh vegetables. Blocked blood vessels require oral antithrombotic drugs such as aspirin and clopidogrel, and some patients need to be given anticoagulant drugs such as rivaroxaban and low molecular heparin sodium. Patients with acute attacks can be treated with intravenous thrombolysis, and common thrombolytic drugs include reteplase. Patients with acute blockage of blood vessels can also undergo surgical treatments, such as incision and removal of thrombus or stent implantation, to open up the occluded blood vessels and prevent tissue necrosis from occurring. Blocked blood vessels mostly require comprehensive treatment, with medication or surgery on top of dietary medications, under the guidance of a medical professional.
