Diagnosis and management of congenital umbilical arteriovenous malformation

Abstract

AbstractAn 8-day-old neonate was presented with severe respiratory distress and diagnosed as primary pulmonary hypertension of the newborn on functional echocardiogram. Evaluation showed bounding pulse, enlarged umbilical cord, and bruit over the periumbilical region. Transthoracic echocardiography and CT angiogram showed a large fistulous communication between the umbilical vein and artery suggestive of congenital umbilical arteriovenous malformation leading to high-output cardiac failure and pulmonary artery hypertension. The patient was stabilised with medications and ventilation. Transcatheter closure of communication was done using coils, vascular plug, and KONAR-MFTM device. The patient improved from heart failure soon after the procedure and thriving normally at 6 months of follow-up.
