Abstract
|
|
|
|
A bronchial artery embolization (BAE) is an important therapeutic method used to control acute and chronic hemoptysis. We report a case of multiple micro-infarcts involving both the kidneys and spleen, following a BAE with 500-700 μm crossed-linked tris-acryl microspheres (Embospheres) in a patient with bronchial artery pulmonary vein shunts. The superior penetration characteristics of the microspheres may have resulted in the greater tendency to cross the bronchial artery pulmonary vein shunts, which subsequently caused the systemic infarcts in our patient. We propose the use of larger sized microspheres (700-900 μm), which may aid in avoiding this complication.
