Summary

Bronchial artery embolization (BAE) effectively controlled massive hemoptysis in 10 cases. Selective angiography is crucial, and microparticle embolization is safer than mechanical coils alone for BAE.

Area of Science:

  • Interventional Radiology
  • Pulmonary Medicine
  • Vascular Imaging

Background:

  • Massive hemoptysis poses a significant clinical challenge, often requiring urgent intervention.
  • Conservative and bronchoscopic methods may fail to control severe bleeding from the bronchial arteries.

Purpose of the Study:

  • To evaluate the efficacy and safety of bronchial artery embolization (BAE) in managing massive hemoptysis.
  • To assess the diagnostic yield of selective versus non-selective angiography in identifying the source of bleeding.

Main Methods:

  • Retrospective analysis of 10 patients who underwent BAE for massive hemoptysis unresponsive to other treatments.
  • Utilized digital subtraction angiography with selective bronchial catheterization using 4F glide Cobra (C2) catheters.

  • Employed polyvinyl alcohol (PVA) particles, Embosphere microspheres, mechanical coils, or a combination for embolization.

    • Main Results:

    • BAE successfully controlled hemoptysis in all 10 patients during the initial session.
    • Underlying causes included tuberculosis, sarcoidosis, bronchiectasis, and malignancy.
    • Two cases with recurrence after mechanical coil embolization were successfully retreated with microparticle embolization.

    Conclusions:

    • Selective bronchial angiography is essential for accurate diagnosis of the vascular pathology causing hemoptysis.
    • Using the same catheter for angiography and embolization can reduce costs.
    • Microparticle embolization appears safer and more effective than sole reliance on mechanical coils for BAE.
