Insights
A child with Abernethy malformation and a unique portal vein-coronary sinus connection developed hepatoblastoma. This is the first documented case of hepatoblastoma in type 2 Abernethy malformation.
Area of Science:
- Vascular malformations
- Pediatric oncology
Background:
- Abernethy malformation is a rare congenital portosystemic shunt.
- It can be associated with serious complications, including liver tumors.
Observation:
- A pediatric patient presented with a rare Abernethy malformation variant, featuring an anomalous connection between the portal vein and coronary sinus.
- The patient was monitored for 30 months.
Findings:
- The patient was diagnosed with hepatoblastoma, a known complication of Abernethy malformation.
- This is the first reported instance of hepatoblastoma in a patient with type 2 Abernethy malformation.
Implications:
- This case highlights the importance of long-term surveillance for Abernethy malformation patients.
- It expands understanding of Abernethy malformation variants and associated oncological risks.
Abstract:
We report the case of a child with Abernethy malformation with an anomalous connection between the portal vein and the coronary sinus. After 30 months of close follow-up, the patient developed hepatoblastoma, a previously documented complication of the Abernethy malformation. This case reports a unique variant of Abernethy malformation and documents the first reported case of hepatoblastoma in a patient with type 2 Abernethy malformation.

Hepatic Portal System

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
Fetal Circulation
