The study emphasizes six case analyses of abdominal aorta-hepatic artery-umbilical vein fistula using HD-flow render mode and STIC. Postnatal outcome evaluations were performed at our medical facility. The fistulas formed a connection between the abdominal aorta and the umbilical vein. HD-flow render mode and STIC were acquired in all six cases. In three cases, fistulas with a diameter >3 mm were associated with extracardiac structural abnormalities and congenital heart defects. The incidence of heart failure was higher when the ratio of the fistula diameter to the umbilical vein diameter was >0.65 and to the abdominal aorta diameter was >0.9. Three fetuses were viable to survive, while three did not, including one that died in utero.

The performance of the nomogram was better than that of the traditional logistic regression and ML models, and comparable to that of the expert model. Additionally, the multimodal nomogram outperforms sonographers with 3- and 6-year experience, and performs only slightly worse than the sonographer with 10-year experience.
