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

Abstract

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.
