A male infant with high-output heart failure who had been found to have a hepatic arteriovenous malformation by ultrasound imaging was referred to our center (Department of Diagnostic and Interventional Radiology, Imam Khomeini Hospital, Tehran University of Medical Sciences, Islamic Republic of Iran) for further evaluation. Computed tomography angiography revealed a large hepatic arteriovenous malformation with feeders originating from enlarged hepatic arteries and draining to enlarged hepatic veins. We performed a transcatheter embolization of the anomaly using ethylene vinyl alcohol copolymer (Onyx) during a single session. The cardiac function of the infant rapidly improved after the procedure. Over the 19 months of follow-up, his cardiac output remained stable and within the normal limits, and no complications were detected.
一名男性婴儿因心输出量过高导致心力衰竭，超声检查发现其存在肝动静脉畸形，遂被转至我院（伊朗德黑兰医科大学伊玛目霍梅尼医院放射诊断介入科）进一步评估。计算机断层血管造影显示存在大型肝动静脉畸形，其供养动脉起源于增粗的肝动脉，引流至增粗的肝静脉。我们在单次介入治疗中使用乙烯-乙烯醇共聚物（Onyx）对该畸形进行了经导管栓塞。术后，患儿心功能迅速改善。在 19 个月的随访期间，其心输出量保持稳定且处于正常范围内，未发现任何并发症。
