Successful Embolization of Hemorrhagic Hepatic Hydatid Cyst Followed by Surgical Resection: Report of Two Cases and Review of the Literature.

Hepatic hydatid cysts (HHCs) are common in endemic areas. Mostly they are asymptomatic, but some cause serious complications. We report 2 cases of HHC complicated arterial bleeding. Owing to signs of active bleeding, the patients were treated with selective embolization of the hepatic artery to stop the bleeding and stabilize the patients' condition. Subsequently, partial hepatectomy of the involved liver lobe was performed in an elective setting and without postoperative complications. We recommend bridging therapy by selective angiography and embolization for hemorrhagic hepatic hydatid cyst before definitive surgical treatment.
