Results: The median follow-up was 10.5 years (range, 5.5–14.5 years). There were no operative deaths but only one late death. One patient required balloon angioplasty because of left PA stenosis. CT showed significant growth of the tracheal lumen diameter in all six patients. The mean diameter of the narrowest section of the trachea increased from 2.2 mm to 3.9 mm after the PA sling repair (p<0.01). Additionally, the stenotic segment ratio improved from 54% to 26% after the PA sling repair (p<0.01).
