| Core Tip |
Preduodenal portal vein is an extremely rare congenital vascular anomaly that can complicate pancreaticobiliary surgery. We report a case of distal bile duct cancer with preduodenal portal vein and multiple congenital anomalies, including median arcuate ligament syndrome, intestinal malrotation, polysplenia, and pancreatic hypoplasia. Preoperative illustration-based vascular simulation, generated through careful review of the original computed tomography dataset, enabled precise understanding of the anomalous anatomy and clinically relevant collateral flow patterns. This directly influenced the surgical strategy, allowing safe completion of total pancreatectomy. This case highlights the practical value of careful preoperative vascular assessment and surgeon-directed schematic integration in complex pancreaticobiliary surgery. |
