A Case Report: Type II Abernethy Malformation Complicated with Congenital Polydactyly and Enlargement of all Cardiac Chambers

Abstract

Abernethy malformation is a kind of congenital malformation of the portal vein system caused by abnormal portacaval shunts. It can be in combination with many other congenital malformations. There has been a limited number of patients since the first patient was reported, leading to limited knowledge of this kind of disease. In August 2018, we treated a patient diagnosed with type II Abernethy malformation complicated with both congenital polydactyly and enlargement of all cardiac chambers, which is extremely rare and can be supplementary to the existing cases. According to a comprehensive and adequate assessment of patients' condition, we treated him with oral silybin (70 mg every time and 3 times a day) for 3 months, and advised him to make follow-up visits. At the latest follow-up, we knew the health condition of this patient was generally satisfactory, whether in terms of laboratory test results or his daily life experience. Although the major therapy for Abernethy malformation is surgery, this case suggests that simple conservative treatment with regular follow-up visits can be suitable for certain patients.
