Pulmonary artery banding

Last revised by Joshua Yap on 28 Jul 2022

Pulmonary artery banding is a palliative surgical procedure used to decrease excessive pulmonary blood flow. It is usually used for neonates and infants with left-to-right shunts unable to withstand complete surgical correction.  

Some indications include:

The current technique of pulmonary artery banding usually involves encircling the main pulmonary artery with a ring of prosthetic material, which restricts pulmonary blood flow, increases systemic perfusion and protects the pulmonary vasculature from changes of pulmonary hypertension

Complications of pulmonary artery banding include:

  • dilatation of the proximal pulmonary artery
  • pulmonary valve insufficiency
  • pulmonary valve injury
  • band migration which may compromise blood flow

The procedure was introduced by William H Muller, Jr and J Francis Dammann, Jr in 1951 and was initially used in an infant with a ventricular septal defect.
