Findings and procedure details
The interventional radiologist starts the procedure with puncture of the right common femoral artery using the Seldinger technique,
and a 5-French (F)
sheath insertion.
The bronchial arteries is usually selected with a Cobra catheter and an angiography is performed showing increased vascularity.
Usually, no active extravasation of contrast material is shown by angiograhy.
A 3F microcatheter is used so as to super-selectively catheterize bronchial arteries.
Embolization is performed by injection of 500 to 700 micron particles until blood stasis is achieved.
Particle embolization is the standard because it allows for repeat embolization procedures if bleeding recurs.
The most catastrophic complication of BAE is paralysis due to inadvertent anterior medullary artery embolization.
Visualization of this “hairpin” vessel is usually considered a contraindication to embolization.
