What is the purpose of pulmonary artery banding?

The physiologic purpose of a PAB is to protect the pulmonary vasculature by reducing excessive pulmonary blood flow and restricting the pressure load to the pulmonary bed, thereby preventing pathologic remodeling of the pulmonary vasculature and pulmonary hypertension.

How is PA banding done?

Surgical technique The band is wrapped around the main pulmonary artery and fixed into place. Once inserted, the band is tightened, narrowing the diameter of the pulmonary artery to reduce blood flow to the lungs and reduce pulmonary artery pressure.

When is PA banding done?

Pulmonary artery banding (PAB) is a palliative procedure that is used as part of staged treatment before definitive surgical correction of congenital heart defects. The aim of PAB is to reduce the diameter of the main pulmonary artery, decreasing blood flow and reducing pulmonary artery pressure.

Is PA banding open heart surgery?

PA banding is a palliative treatment particularly reserved for those patients who are unable to withstand an open heart procedure for total correction. In the case of VSD, pulmonary artery (PA) banding increases the resistance to blood flow through the pulmonary artery.

Where does the pulmonary artery receive blood from?

Function. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.

How much does arterial switch surgery cost?

The median costs were $60,000, in 2012 dollars (range: $25,000 to $549,000). The median age at operation was 5 days (range: 1 to 12 days).

How long does the Glenn procedure take?

How long does the Glenn procedure take? This surgical procedure typically takes four to five hours and the recovery time is generally shorter than after the Norwood.

What is pulmonary artery banding surgery?

Surgical Technique. The goal of PAB is to reduce pulmonary artery pressure and excess pulmonary blood flow. PAB involves the insertion of a band around the pulmonary artery to reduce blood flow into the lungs. A variety of banding materials are used; one commonly used material is polytetrafluoroethylene.

What is the procedure for lung surgery?

Lung surgery – Lung surgery using a thoracotomy is called open surgery. In this surgery 1 You will lie on your side on an operating table. Your arm will be placed above your head. 2 Your surgeon will make a surgical cut between two ribs. 3 Your lung on this side will be deflated so that air will not move in and out of it during surgery.

What happens when the pulmonary band becomes too narrow?

The pulmonary band can also migrate away from the original placement and lead to stenosis, in which the blood vessel becomes too narrow. There have also been reports of hardening of the vessels around the band due to buildup of calcium deposits and scarring of the pulmonary artery wall beneath the band, which can also inhibit blood flow.

What is the prognosis of pulmonary artery banding (PA banding)?

Although PA banding was performed in the past in small infants with large PBF and CHF, primary repair of the defect is currently recommended by many centers. The banding produces distortion of the PAs and does not necessarily prevent pulmonary vascular obstructive disease. The procedure is associated with a high mortality rate, as high as 30%.
