Coil embolization of arterioportal fistula complicated by gastrointestinal bleeding after Caesarian section: A case report

BACKGROUND Most intrahepatic arterioportal fistulae (IAPF) are acquired. The few cases of congenital fistulae are diagnosed in infants and children. CASE SUMMARY We report a 31-year-old female patient presenting with haematemesis and melena three weeks after delivering her second child. The patient had a 20-year history of abdominal distention and nausea. IAPF, along with splenomegaly and ascites, was found by Doppler sonography and confirmed by computed tomography angiography. The patient was treated with endovascular coil embolization, resulting in occlusion of the fistula. CONCLUSION This was an unusual case of possible congenital IAPF that manifested during a second pregnancy and was complicated by portal hypertension.
