Lysis and Recanalisation

The lysis of thrombus occurs due to natural fibrinolytic activity. It may take few hours to several months. Immediate lysis may prevent detection of thrombosis on investigative modality. In muscular calf vein thrombosis involving medial gastrocnemial vein and soleal vein, complete recanalisation was detected in 54.8% at 1 month, in 84.7% at 3 months and in 96% at 9 months [8]. The continuation of anticoagulation was decided based on findings at 1 month. In patients with aetiology restricted to short duration as postoperative status, spontaneous lysis of thrombus has been observed in 72–88% of patients within 3 months [7]. So generally, lysis seems to be the common fate of IDDVT while persistence and/or extension is more often associated with presence of malignancy.
