Palliating severe arteriovenous fistulae using absorbable pulmonary artery bands.

We report the use of an absorbable pulmonary artery band to limit postoperative cyanosis due to severe pulmonary arteriovenous fistulae in a 5-year-old girl with post-Fontan palliation takedown to a two-ventricle repair. At 1-year postoperatively, her fistulae had nearly resolved with no distortion of her pulmonary artery anatomy. This case demonstrates a novel approach to limiting cyanosis while pulmonary arteriovenous fistulae resolved after redirection of hepatic blood flow to the affected lung.
