“For a new patient with acute DVT, if he or she has no contraindications for thrombolysis, especially with a life expectancy more than one year, we prefer to perform catheter-based interventions, including catheter-directed thrombolysis, pharmacomechanical thrombolysis, ultrasound-assisted catheter-directed thrombolysis and subsequent percutaneous transluminal angioplasty and stenting,”Dr. Li said.”But, of note, anticoagulation is the basic treatment whatever catheter-based interventions are adopted.”
