Summary

This study investigated ultrahigh-dose streptokinase therapy for arterial occlusions. Favorable outcomes were observed in specific cases of femoral and iliac artery blockages treated with this regimen and subsequent angioplasty.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Thrombolytic Therapy

Background:

  • Arterial occlusions pose significant challenges in vascular treatment.
  • Effective thrombolytic strategies are crucial for limb salvage and improved circulation.
  • Catheter-based interventions complement medical therapy for persistent stenoses.

Purpose of the Study:

  • To evaluate the efficacy of an ultrahigh-dose streptokinase regimen for arterial occlusions.
  • To assess the role of percutaneous transluminal angioplasty (PTA) in conjunction with thrombolysis.
  • To identify patient subgroups that benefit most from this therapeutic approach.

Main Methods:

  • Administration of ultrahigh-dose streptokinase (1.5 million units/hour for 6 hours).
  • Subsequent percutaneous transluminal angioplasty (PTA) for non-responders or residual stenoses.

  • Analysis of treatment outcomes based on occlusion characteristics (age, location, length, number of open arteries).
  • Main Results:

    • Favorable results were noted in femoral occlusions up to 6 weeks old.
    • Optimal outcomes in femoral occlusions involved 2-3 open calf arteries and occlusion length <15 cm.
    • Iliac occlusions showed good response to lytic therapy within a 3-month history.

    Conclusions:

    • Ultrahigh-dose streptokinase combined with PTA is effective for select arterial occlusions.
    • Early femoral occlusions and shorter iliac occlusions (<3 months) respond best.
    • Treatment success is influenced by occlusion characteristics, guiding therapeutic decisions.
