PURPOSE: The ideal material for pediatric pulmonary artery (PA) augmentation is autologous pericardium. However, its utility for multistaged operations is limited. In this study, we applied an in vivo tissue-engineered autologous Biotube graft to a patient with congenital heart disease for the first time.
DESCRIPTION: For molds of the Biotubes, two silicone 19F drain tubes were embedded in the subcutaneous spaces of a 2-year-old girl with a diagnosis of pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries during palliative surgical procedures. When definitive repair was performed after 8 months, the implants were removed to prepare Biotubes, one of which was cut open and autologously implanted into the PA for patch augmentation.
EVALUATION: Seven months after implantation, the Biotube patch-augmented PA tolerated balloon angioplasty (BAP) for residual stenosis of the peripheral PA. Computed tomography images after BAP showed the well-preserved shape of the Biotube patch-augmented PA. Neither aneurysm formation nor stenosis was observed.
CONCLUSIONS: The safety and feasibility of Biotubes for pediatric PA patch augmentation are described. Because Biotubes are completely autologous, they may be ideal material for pediatric PA augmentation.
