Surgical ligation is performed to address specific neonatal disorders that cannot be managed through medical therapy alone. Common indications include:
- Patent Ductus Arteriosus (PDA): A PDA that remains open can lead to heart failure, pulmonary hypertension, and other complications. Ligation helps close the ductus arteriosus, thereby preventing abnormal blood flow. - Congenital Heart Defects: Some heart defects may require ligation of abnormal vessels to improve blood circulation and oxygenation. - Necrotizing Enterocolitis (NEC): In severe cases, ligation of affected blood vessels may be necessary to prevent further bowel damage.
