• Change From Baseline to Final Angiographic Results [ Time Frame: Index Procedure ( pre-endovascular treatment and post-endovascular treatment) ] [ Designated as safety issue: No ]

  From the Index Procedure's Baseline (pre-endovascular treatment) and Final (post-endovascular treatment) angiograms,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 value from the final value.

  
  

• Rethrombosis [ Time Frame: 3 Month Follow Up ] [ Designated as safety issue: No ]
  The number of patients that had rethrombosed in the vessels treated during the index procedure (initial endovascular procedure).
  
  
• Description of Treatments by Thrombotic Condition [ Time Frame: Index Procedure ] [ Designated as safety issue: No ]
  The # of patients that were exposed to each treatment at least once in the given thrombotic condition.
  
  

The PEARL Registry collects real world data about mid-length AngioJet catheters to:

• Characterize usage patterns, treatment approaches, and targeted vessels
• Document treatment strategies, including specific techniques and concomitant therapies
• Collect outcome data during initial hospitalization and at a 3-month follow-up phone call or visit
• Evaluate the frequency of specific clinical events in relation to risk factors, diagnosis, and treatments provided
• Identify treatment strategies that may optimize procedural and clinical outcomes, to facilitate development of treatment guidelines
• Offer sites a valuable resource for tracking usage and performance of the AngioJet System at their institution

Information collected by the PEARL Registry is intended for educational and clinical research purposes only.
