TAE Combined with Microwave Ablation in the Treatment of Rare Giant Hepatic Hemangioma:Case Report and Literature Review

Abstract

Background: hepatic hemangioma is the most common benign tumor of the liver. However, patients with large hemangiomas that cause compression symptoms or that are at risk of rupture may need further intervention. It is necessary to explore additional minimally invasive and personalized treatment options.Case presentation: A 47-year-old female was diagnosed with right hepatic hemangioma for more than 10 years. Abdominal contrast-enhanced CT and CEUS revealed that there was a large hemangioma in the right liver, with a size of approximately 95x97x117 mm. Due to the patient's refusal of surgical treatment, hepatic artery embolization was performed in the first stage, then after 25 days of liver protection treatment, the liver function indexes decreased to normal levels. Then, B-ultrasound-guided microwave ablation of the giant hepatic hemangioma was performed. Ten days after the surgery, hepatobiliary ultrasonography showed that the hemangioma of the right liver was smaller than the previous size (the volume was reduced by approximately 30%). Then the patient was discharged from the hospital, and CT suggested that the hepatic hemangioma is significantly smaller two months after discharge. Because of COVID-19, the patient's CT examination was delayed.Conclusions: TAE combined with microwave ablation is a safe and effective minimally invasive treatment for hepatic hemangioma.
