Peripheral Vascular Disease Embolism and Thrombosis Venous Thrombosis

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: PEARL II: PEripheral Use of AngioJet® Rheolytic Thrombectomy With a Variety of Catheter Lengths

Further study details as provided by Boston Scientific Corporation:

Primary Outcome Measures:
  • Change in Degree of Occlusion From Baseline to Final Angiogram/Venogram. [ Time Frame: Day 1 ]

    From the Index Procedure's Baseline (pre-endovascular treatment) and Final (post-endovascular treatment) angiograms/venograms, each vessel was assigned a value by the treating physician.

    1. complete occlusion (>90% occlusion);
    2. substantial occlusion (50-90% occlusion OR <50% occlusion and >3cm in length);
    3. partial occlusion (<50% occlusion AND <3cm in length)
    4. patent (without visable thrombus or occlusion) The levels of change (improvement) were calculated by subtracting the baseline assigned angiographic/venographic value from the final value.

  • Rethrombosis [ Time Frame: 3 Month , 6 Month and 12 Month Follow Up ]
    The number of patients affected by rethrombosis of the treated vessels (first episode) throughout a 12 Month Follow-Up.

Secondary Outcome Measures:
  • Concomitant Treatments Used With the AngioJet® System [ Time Frame: Day 1 ]
    The # of patients exposed to each treatment option at least once in the given thrombotic condition during the Index Procedure

Enrollment: 500
Study Start Date: January 2010
Study Completion Date: September 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Limb Ischemia
Patients presenting with limb ischemia for treatment
Deep Vein Thrombosis
Patients presenting with deep vein thrombosis for treatment
Hemodialysis Access
Patients presenting with thrombosed hemodialysis access for treatment
Other Thrombotic Conditions
Patients presenting with a thrombotic condition other than limb ischemia, deep vein thrombosis or thrombosed hemodialysis access for treatment

Detailed Description:

The PEARL II Registry is a prospective, multi-center, observational registry including 500 patients who meet eligibility from up to 50 sites worldwide. Patient participation will be 12 months including post procedure follow-up contact at 3, 6 and 12 months. The study duration is estimated at 36 months.

A patient's treatment is determined by the treating physician based on the clinical situation and local practices. In contrast to a randomized, controlled trial, there are no pre-defined experimental interventions.
