Hi welcome to the health care magic Your diagnosis is DVT with pulmonary embolism... For this how long you have taken rivaroxaban (xarelto)??? This drug is gold standard in DVT prophylaxis and depending on D dimer level and according to cause it s duration of treatment decided Aspirin is anti platelet drug and also beneficial in preventing thrombosis Your cause for dvt should be searched for esp I want to check anticardiolipin (for antiphospholipid syndrome), prothrombin gene mutation by PCR, factor v Leiden mutation, protein C and S deficiency If genetic mutation present then high chance of recurrent thrombosis and life long anticoagulant drug might needed You can wear compression stocking Hope your concern solved Take care
