title: Magnetic resonance imaging findings of persistent primitive hepatic venous plexus with complex congenital cardiac disease.
abstract: Persistence of the primitive hepatic venous plexus (PPHVP) is an uncommon anomaly that can present associated with complex congenital heart disease and inferior vena cava (IVC) development anomalies and complicate endovascular and surgical procedures. We report a case of PPHVP in a patient with complex congenital heart disease with unexplained persistent arterial desaturation after Kawashima operation and describe magnetic resonance angiography (Angio-MRI) findings leading to the diagnosis. We recommend that IVC-Angio-MRI be performed in preoperative evaluation of patients with complex congenital heart disease and left isomerism when redirection of systemic venous blood to the pulmonary arterial circulation is considered.
