Abstract
Background: The systemic-to-pulmonary artery shunt has been widely used to promote pulmonary blood flow and support the development of the pulmonary artery, continued working as the main palliative treatment for patients with insufficiency pulmonary flow. This study aims to evaluate the potential for pulmonary artery growth after systemic-to-pulmonary shunt operation at Vietnam National Children’s Hospital.
Methods: A retrospective study was conducted with 100 patients who underwent systemic-to-pulmonary shunt operation from January 2018 to December 2023 at Vietnam National Children’s Hospital.
Results: Within a mean time of follow-up of 11.23 ± 8.42 months, the pulmonary artery size increased significantly, with the Nakata Index increased from 116.1 ± 45.5mm/m² to 247.9 ± 110.2mm/m² and the McGoon Index increased from 1.25 ± 0.25 to 1.91 ± 0.41. There were no differences between two surgical strategies (BT shunt and modified Melbourne shunt) in the increased pulmonary artery size effect (p>0.05). Univariate analysis revealed that the existent forward pulmonary blood flow significantly affects the growth of the pulmonary artery (p<0.05).
Conclusions: Following systemic-to-pulmonary shunt surgery, the pulmonary artery size grows considerably. Forward flow via the pulmonary valve has a beneficial effect on the development of the pulmonary artery following a systemic-to-pulmonary shunt procedure in the congenital heart group.
