Pulmonary artery stent implantation in children with single ventricle malformation before and after completion of partial and total cavopulmonary connections.

摘要: Objectives: Relief of pulmonary artery stenosis before and after cavopulmonary connections (CPC) in patients with single ventricle malformation is essential to optimize hemodynamics. We evaluated the risk factors for assessed outcome stent implantation. Interventions: Seventeen stents twelve were implanted CPC at a mean age 4.5 (0.1–17.6) years. Results: Fourteen placed left (82%) three right (18%). One was intraoperatively. Mean time between surgery implantation 28 (1–132) months. The (SD) size 3.1 ± 2.1 mm 8.1 3.3 (P < 0.001) implantation. Six out seventeen (35.2%) had be redilated interval 19 (5–48) Two patients’ removed during next surgical procedure; both needed an early restenting affected vessel. There no procedure-related complications or redilatation. Anatomical aortic arch hypoplastic arteries, whereas dilatation ascending aorta LPA Blalock–Taussig shunt RPA factors. Conclusions: Stent treat pediatric effective can realized safely. Close follow-up recommended stenosis. During total connection, previously that site should place changed hybrid procedure larger diameter, because etiology may persist removal could result vessel injury promotes restenosis.
