In our experience, duct closure with the Amplatzer duct occluder II is a safe and effective method. The advantages of using it are the smaller sheath sizes and softer shape.
Our initial results show that AndraStents are implantable and efficacious in different vascular stenoses and present a valuable alternative to the available large stents. With the application of a modified front-loading technique, they can also be implanted in smaller children.
OBJECTIVES: To present our experience with stent implantations in non-surgically treated patients with pulmonary atresia, ventricular septal defect and stenotic aortopulmonary collaterals. METHODS: Between April 2007 and June 2009, 6 stents in 4 patients were implanted into stenosed segments of MAPCAs. The median age and weight of patients at stent implantation were 24 years (range 13-34 years) and 58.5 kg (range 56-70 kg), respectively. RESULTS: All implantations were successfully performed; there were no procedure associated complications. The median diameter increase of stenosed MAPCAs was 107 %. The mean arterial blood saturation increased from mean 78 % to 84 %. An early increase in the median exercise duration measured by 6MWT was 36 %. Neointimal in-stent fi broproliferation in 4/6 stents and stent fracture in 1/6 patients occured in mid-term follow-up. CONCLUSION: Percutaneous catheterizational stent implantation into stenosed segments of MAPCAs is a palliative procedure, that might improve quality of life of non-surgically treated patients with PA, VSD, MAPCAs. Neointimal in-stent fi broproliferation and stent fracture can be expected as complications in mid-term follow-up. CT-angiography is recommended to confi rm these complications in progressive satO 2 decrease (Fig. 3, Ref. 12). Text in PDF www.elis.sk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
