Management of giant liver hemangioma.

Abdelkader Boukerrouche*

Liver hemangiomas are the most common benign vascular neoplasms of the liver and are often diagnosed incidentally during abdominal surgical procedures or in abdominal imaging studies. Liver hemangioma is qualified giant when its diameter exceeds 5 cm. The natural progression of giant hemangiomas is not clearly defined and the risk of life-threatening complications is not well established. Reported single centers studies demonstrated the safety of expectant management of even very large asymptomatic hemangioma with very low risk of adverse events. Therefore, tumor size alone as an indication for surgery is not supported by any published data. Based on published studies results, the indications of surgery are well defined and with the improvement of liver surgery, surgical resection of liver hemangioma can be performed with nil mortality and very low morbidity. Other therapeutic options as Radiofrequency Ablation (RFA) and Transcatheter Arterial Embolization (TAE) can be considered in some situations.
