What is PDA ligation?
When the condition is present, a vein that normally closes at birth (the ductus arteriosus) stays open. The result is that oxygen-rich blood that should be circulating into the body instead goes back to the lungs. PDA ligation is a procedure to repair this problem.
Which drug is used for closure of PDA?
Indomethacin is the most commonly used agent for medical closure of a ductus. Most studies have shown that the use of indomethacin in closing the PDA has reduced the need for subsequent surgical closure.
How long does it take for PDA to close in premature babies?
Closure of the DA is initiated by an increase in oxygen and changes in pulmonary and systemic blood pressure (1). In full-term newborns, the DA routinely closes within one to five days after delivery (2).
What is PDA closure surgery?
A transcatheter PDA closure is a minimally-invasive (non-surgical) procedure to close the ductus arteriosus. Specialized heart doctors called pediatric cardiac interventionists use a procedure called cardiac catheterization to place a small device in the vessel, which closes the PDA.
How long does PDA ligation take?
The procedure usually takes one to three hours. After the procedure, your child will go to the recovery room for one to six hours to wake up from the anaesthesia.
Is PDA surgery considered open heart surgery?
Patent ductus arteriosus (PDA) surgery is done to close a blood vessel called the ductus arteriosus. Normally, this blood vessel closes after birth. But in PDA, it stays open. This causes some of the blood that should go from the heart to the body to go to the lungs instead.
Why is ibuprofen given in PDA?
Ibuprofen is as effective as indomethacin in closing a PDA. Ibuprofen reduces the risk of NEC and transient renal insufficiency. Therefore, of these two drugs, ibuprofen appears to be the drug of choice.
Which drug is commonly used to open the ductus arteriosus?
Alprostadil (Prostin VR Pediatric) Alprostadil is used to maintain the patency of the ductus arteriosus when a cyanotic lesion or interrupted aortic arch presents in a newborn. Prostaglandin E1 (PGE1) is most effective in premature infants.
Is PDA life threatening?
It is important to correct PDA because it can lead to congestive heart failure and a disease of the right side of the heart (called cor pulmonale) later in life. PDA also increases the risk of endocarditis, a life-threatening infection of the lining that covers the heart chambers, valves, and main arteries.
What size is a large PDA?
A PDA is considered small at <1.5 mm, moderate when it ranges between 1.5 and 3 mm, and large if the dimension exceeds 3 mm. SAX should not be chosen to measure ductal size because it is not always possible to differentiate the left pulmonary artery from the DA.

Is PDA open heart surgery?
PDA surgery is done on the blood vessel, not the heart.
