Abstract: 【Abstract】 Objective: Creation of a systemic-to-pulmonary shunt is still the firstline treatment in neonates with ductdependent pulmonary circulation, or in patients with hypoplastic left heart syndrome as a part of the first stage of the Norwood sequence. Acute complications after such surgery, such as stenosis, thrombosis, or kinking, are potentially lifethreatening. These complications require immediate revision or exchange of the shunt. In this report, we discuss interventional treatment as an alternative to surgery in 3 patients with acute stenosis of a shunt. Methods:The age of the patients ranged from 4 to 6 months, and their weights ranged between 4.2 and 6.2 kg. In 1 patients, the shunts were modified Blalock-Taussig type, while the 2 patients had shunts from the right ventricle to the pulmonary arteries.Results:We implanted 5 coronary arterial stent systems in 4 interventions. The diameter of the balloon used for implantation had a ratio to the shunt of 1. to 1. All shunts were successfully reopened by stenting. During follow-up, 3 patients underwent further procedures on an elective basis. Conclusion: In our limited experience, implantation of stents is an effective treatment for complications of shunts.
