BACKGROUND Congenital intrahepatic arterioportal fistula(IApF) is a rare vascular malformation in infants that causes severe portal hypertension(pH) with poor prognosis if untreated. Currently, radiological embolisation is considered the first-line therapy for simple IApF; however, it might be not resolutive for complex hepatic vascular lesions. When endovascular embolization is not sufficient to completely obliterate the IApF, surgical intervention is needed, but it has been associated with severe morbidity and mortality in small ***, indications are not *** SUMMARY We present the first case of a 6-month-old girl with trisomy 21 affected by a complex congenital IAFp, which caused severe pH, successfully treated with an endovascular-surgical hybrid procedure. The novel technique comprised a multistep endovascular embolisation, including a superselective transarterial embolisation of the afferent vessels and a direct transhepatic embolisation of the dilated portal vein segment, combined with selective surgical ligation of the arterial branches that supply the fistula, which were too small to be *** complex IApF was also associated with severe cholestasis and intra/extrahepatic biliary tree dilatation, which was successfully treated by a temporary biliary drainage. At 24-mo follow-up, the hybrid endovascularsurgical procedure achieved complete occlusion of the complex IApF and resolution of the pH. A comprehensive review of the literature on congenital IApF management, focussed on alternative treatment strategies, is also *** The combined radiological-surgical approach is a safe and effective treatment option for complex IApF and avoids major invasive surgery.
