Recanalisation of a vein post acute deep venous thrombosis involves remodeling of the thrombus. This is a complex process of adhesion of the thrombus to the wall of the vein, an inflammatory response of the vessel wall leading to organization and subsequent contraction of the thrombus, neovascularization and spontaneous lysis of areas within the thrombus. A fibrous membrane may remain in the vein which is called a synechia . This can be better visualised with colour Doppler where blood can be seen flowing on either side of the synechiae.
