The goal of the study is to see if local anti-inflammation helps prevent re-thrombosis of the blood vessel and improvement in symptoms for up to 24 months after the initial DVT recanalization procedure.</objective><nct_id>NCT04862468</nct_id><sponsor_type>Industrial</sponsor_type><age_group>Adult</age_group><treatment_type>Treatment</treatment_type><treatment>Combination Product: Perivascular dexamethasone&#xD;
