Carotid artery cut-down technique for ductus arteriosus stenting.

Background: This study aims to evaluate early and mid-term outcomes of ductal stenting via carotid artery surgical cut-down technique in neonates. Methods: Between January 2015 and January 2022, a total of 17 neonates (12 males, 5 females; median age: 14 days, range, 5 to 34 days) who underwent carotid artery surgical cut-down technique for ductal stenting were retrospectively analyzed. Diagnoses of the patients, demographics, procedural success/failure, access-related complications, and neuroimaging findings were recorded. Results: The primary indication for ductal stenting was pulmonary atresia in all patients. All patients who underwent carotid cut-down had vertical anatomy, with or without tortuous ductal anatomy, and they were not suitable for the femoral approach. The median body weight was 3 (range, 2 to 3.4) kg. Fifteen of the 17 interventions (88.2%) were successful. Two patients whose stenting failed underwent a systemic-to-pulmonary shunt operation. The early in-hospital mortality rate was 17.6% (n=3). No neurological or accessrelated complications were observed in any of the patients. Conclusion: Stenting the ductus arteriosus with challenging anatomy is feasible and safe with carotid artery cut-down, particularly in small neonates. Based on our study findings, this technique may offer an effective and less invasive alternative to the systemic-to-pulmonary shunt operation.
