Cutting balloon angioplasty and stent implantation for left pulmonary artery stenosis in a case with Alagille syndrome

Alagille syndrome is a rare autosomal dominant disorder associated with an impaired development of intrahepatic bile ducts, cardiac, skeletal, eye, kidney disorders, and characteristic facial appearance. Peripheral pulmonary stenosis is the most frequently seen cardiac anomaly in patients with Alagille syndrome. In this article, we report a case who was diagnosed with Alagille syndrome due to the coexistence of neonatal cholestatic jaundice, posterior embryotoxon, characteristical facial appearance, and peripheral pulmonary stenosis. Symptomatic relief was achieved by cutting balloon angioplasty and stent implantation applied when the degree of the left pulmonary stenosis increased at four years of age.
