AORTOPULMONARY COLLATERALS

What is it
They are abnormal communicating vessels found in babies born with cyanotic defects in the heart. The vessels run from aorta, the main artery arising out of the heart and reach to the lungs, and are essentially nature’s way of compensating for the defect.

Why is it done?
This is undertaken to stop the extra flow to the lungs before corrective surgery.

How is it done?
Percutaneously from the artery of groin using coils.

When is it done?
It is done before the corrective surgery of the lesion.

How is it done?
This is achieved by accessing the vessels from groin, and using coils to close them.

Before
The patient needs a full evaluation and preparation requires at least 6 hrs of fasting.

After
The patient should be watched for any excessive bleeding from the puncture site besides keeping a close watch on vital parameters.
