pulmonary artery banding
Also written as: PAB — Pulmonary Artery Banding
A palliative surgical procedure involving placement of a constricting band around the pulmonary artery to reduce pulmonary blood flow.
Full Definition
Pulmonary artery banding (PAB) is a palliative surgical technique primarily used in congenital heart disease to protect the pulmonary circulation from excessive blood flow and pressure. A synthetic band is placed around the main pulmonary artery, creating controlled stenosis that reduces pulmonary blood flow and prevents the development of pulmonary vascular disease. This procedure is typically employed as a bridge to future definitive repair in complex congenital lesions, particularly in small infants who are not candidates for immediate complete correction. The band must be carefully sized to achieve optimal balance between protection of pulmonary vessels and maintenance of adequate systemic circulation.
Usage
Usage note: Specify band gradient and clinical indication; distinguish from other PA procedures.
