Application of the 5F JL4 Catheter in Bronchial Artery Embolization With the Opening in the Inferior Wall of the Aortic Arch.

Background: We investigated the efficacy and safety of bronchial artery embolization (BAE) using a 5F JL4 catheter in patients with hemoptysis and a bronchial artery opening in the inferior wall of the aortic arch. Methods: This was a single-center retrospective study. Seventeen patients underwent BAE using 5F JL4. We then evaluated technical success (TS), clinical success (CS), incidence of complications, and hemoptysis recurrence rate (RR). Results: The TS rate of microcatheter superselective catheterization and CS rate after surgery were 100%, and the incidence of severe complications and postoperative RR were 17.6%. Conclusions: Bronchial artery embolization for hemoptysis with a BA opening in the inferior wall of the aortic arch using the 5F JL4 catheter could be a safe method. The short- and medium-term results were excellent. [ABSTRACT FROM AUTHOR]
