Surgical intervention for patent ductus venosus

Area of Science:

• Hepatology
• Pediatric Surgery
• Vascular Anomalies

Background:

• Patent ductus venosus (PDV) is a rare congenital anomaly.
• PDV often presents secondary to hepatic atrophy and liver failure.
• Associated conditions include hypergalactosemia and hyperbilirubinemia.

Purpose of the Study:

• To evaluate the efficacy of surgical interventions for PDV.
• To assess the impact of PDV treatment on biochemical markers and portal hemodynamics.
• To identify potential postoperative complications and management strategies.

Main Methods:

• Surgical treatment of eight PDV cases through ligation or partial banding.
• Intraoperative monitoring of portal vein pressure (PVP) below 30 cm H2O.
• Postoperative monitoring for complications such as portal thrombus.

Main Results:

• Surgical intervention (ligation or banding) improved intrahepatic portal vein flow.
• Postoperative normalization of serum galactose and bilirubin levels.
• Portal thrombus occurred in one case, managed with anticoagulation in subsequent cases.

Conclusions:

• PDV ligation and banding are effective surgical treatments for PDV.
• Close postoperative monitoring is crucial to prevent complications like portal thrombus.
• Surgical correction leads to biochemical and hemodynamic improvements.
