<unk> s may be diagnosed based upon clinical criteria by a healthcare professional. A more specific evaluation can be made by ultrasound. An ultrasound can be useful in situations in which an<unk>  occurs above the knee and is not associated with a varicose vein, because ultrasounds can detect more serious clots like DVTs. The diagnostic utility of D-dimer testing in the setting of<unk> s has yet to be fully established. Classification<unk> s can be classified as either varicose vein (VV) or non-varicose (NV) associated. NV-SVTs are more likely to be associated with genetic procoagulable states compared to VV-SVTs.<unk> s can also be classified by pathophysiology. That is, primary<unk> s are characterized by inflammation that is localized to the veins. Secondary<unk> s are characterized by systemic inflammatory processes. A subclass of<unk> s are septic thrombophlebitis, which are<unk> s that occur in the setting of an infection.
