Recent evidence demonstrates that the severity of post-thrombotic syndrome symptoms is directly related to the level of venous thrombosis and following treatment these subsequent symptoms are inversely related to the degree of thrombus removal. If we can improve, and preferably standardise the terminology associated with pre-treatment assessment of thrombus load and post-treatment success of thrombus removal techniques, we should then be able to choose more tailor-made techniques to greater benefit our patients. A number of scoring systems have been devised for the assessment of venous thrombus burden, with a majority impractical for everyday usage. In order to provide a more practical solution, the lower extremity thrombosis classification has been developed, using information on anatomical location for venous thrombus combined with a clinical indicator as to the likely sequelae. Anatomical success following venous thrombolysis can be defined by assessing restoration of anterograde flow in the treated vein or the percentage degree of thrombolysis, using venography. The second option is the method most frequently utilised, with the Venous Registry grading system applied. Data from recent trials have given us conflicting and confusing data mainly because we are not using standardised terminology. We urgently need to agree on a standard method of description of thrombus removal before stent placement which also incorporates the likely clinical impact of the area involved in the thrombosis.<\/jats:p>","DOI":"10.1177\/0268355516632650","type":"journal-article","created":{"date-parts":[[2016,2,25]],"date-time":"2016-02-25T06:52:41Z","timestamp":1456383161000},"page":"15-23","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["What
