What is the pulmonary artery zone?

Lung banding (PAB) is a surgical method for the treatment of specific congenital heart defects. It is usually used as a temporary measure to treat newborns and infants for pulmonary excessive circulation. Its purpose is to reduce the circulation in the artery long enough for the child to age, stronger and larger than to undergo a large heart surgery. It is also used to slow down the progression of congestive heart failure.

The use of pulmonary artery belt has decreased; However, it is still a preferred palliative method when immediate operation is not a possibility. In some cases, patients are placed on mechanical fans in conjunction to reduce or prevent pulmonary edema. Banding should not be used as a medicine, but should be considered temporary holding until surgical medicine is possible.

Banding of the pulmonary artery placed a band -shaped material around the artery and reduces its size. These reduction in size slows the amount of blood flowing. When blood overflows or prostsKa too violently through the artery, can cause problems with stability of blood pressure, heart rate or the stability of the artery wall. Banding slows the flow to an acceptable amount and speed.

This procedure cannot be used in patients whose atrial arteries do not work well for various reasons. Most patients are pediatric and have either played and shifting left right, or they are pediatric patients with a large arterial transposition (conversion). In the case of transposition, the banding is used to start training the left ventricle before performing the surgery of the arterial switch.

In most cases, the zone pulmonary artery is left to the site for several weeks to several months, after which the surgery is remedied. While waiting for remedial surgery planning, medical staff provides treatment of any infections, monitor the patient's weight and record vital brands. Surgery is performed by a child surgeon.

patients with defects of one ventricular are exposed to increased risk of developing complications from the band. This risk increases when aortic lesions are also present. In these cases, the chamber hypertrophy may arise from the lung zone, so pediatric surgeons proceed carefully when performing banding. In many such cases, the banding is not performed and the operation date will move up.
