Primary Outcome Measures:
  • Treatment success - treated segment has < 25% residual thrombus AND flow is present following administration of microplasmin [ Time Frame: During intervention procedure ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Grade of lysis [ Time Frame: Upon completion of procedure ] [ Designated as safety issue: No ]
  • Limb patency [ Time Frame: Baseline, 48h post procedure, Day-7 and Day-30 ] [ Designated as safety issue: No ]
  • Target limb reintervention [ Time Frame: Day-7 and Day-30 ] [ Designated as safety issue: No ]
  • Clinical outcomes [ Time Frame: Baseline, 48h post procedure, Day-7 and Day-30 ] [ Designated as safety issue: No ]

Experimental: 1 Drug: microplasmin
20mg with Trellis-8 15cm Treatment length 40mg with Trellis-8 30cm Treatment length


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria include:

  • Patients with radiographically-confirmed acute proximal DVT

Exclusion Criteria include:

  • Isolated calf or popliteal vein DVT, based on duplex ultrasound
  • Thrombus involving the inferior vena cava (IVC)
  • Proximal (e.g. cranial) aspect of thrombus cannot be adequately assessed to level of the iliac veins or inferior vena cava, based on duplex ultrasound.
  • Cannot traverse the target vessel segment with guidewire
  • Symptomatic pulmonary embolism is present at time of presentation
  • Documented history of prior DVT in target extremity
  • History of anticoagulants administered for > 30 days for undocumented/ unclear reason (e.g. for reasons other than presence of mechanical cardiac valve, atrial fibrillation, etc.)
  • Documented history of thrombophilic disorder, with diagnosis established via previous objective testing (e.g. familial screening for thrombophilia).
  • Cannot receive standard secondary prevention pharmacotherapy [i.e. heparin or LMWH and vitamin K antagonists (VKA)] due to contraindications to anticoagulation [e.g. known bleeding diathesis, thrombocytopenia (platelets < 100,000 mm3), heparin induced thrombocytopenia (HIT), known allergy to heparin or warfarin]
  • Absolute contraindication to thrombolytic therapy
  • Previous central nervous system haemorrhage
  • Life expectancy less than 1 year, due to other comorbid condition.
  • Previous intervention in target limb to address venous thrombus.
  • Target limb has chronic venous insufficiency of C4 or greater severity
  • Acute or chronic symptomatic musculoskeletal condition in target limb (e.g. trauma, fracture, severe arthritis).
  • Documented patent foramen ovale or other right-to-left cardiac shunt.
  • Absolute contraindication to contrast media or renal insufficiency (baseline creatinine >2.0 mg/dL).
