Multislice computed tomography angiography in pediatric liver transplantation

Area of Science:

• Radiology
• Pediatric Surgery
• Transplantation

Background:

• Preoperative vascular anomaly assessment is vital for surgical planning in pediatric liver transplantation.
• Living-related liver transplantation in children necessitates precise understanding of the hepatic vascular system.

Purpose of the Study:

• To evaluate the efficacy of 3D multislice CT angiography as a replacement for conventional angiography in pretransplant hepatic vascular assessment.
• To determine if 3D CT angiography can provide adequate information for liver transplant evaluations.

Main Methods:

• 3D CT angiography was performed in 38 pediatric patients with biliary atresia.
• Conventional angiography was conducted in 15 patients; 12 underwent transplantation.
• Findings from 3D CT angiography were compared with conventional angiography and intraoperative results.

Main Results:

• 3D CT angiography was successful in 37 patients, accurately depicting the hepatic artery, portal vein, and inferior vena cava.
• The imaging identified vascular pathologies in four patients, deeming them unsuitable for transplantation.
• Significant findings included hepatic artery insults, portal vein issues, portosystemic shunts, and recommendations for venous grafts.

Conclusions:

• 3D CT angiography is a superior tool for demonstrating the pediatric hepatic vascular system and identifying abnormalities.
• It offers advantages over conventional angiography, being less invasive, more convenient, and efficient.
• This advanced imaging significantly impacts patient selection and surgical planning for pediatric liver transplantation.
