Diagnosis and treatment for rupture and bleeding of accessory hepatic aneurysms

Rupture and bleeding of accessory hepatic aneurysms is clinically rare. Computed tomography angiography (CTA) or multislice reconstruction can provide reliable basis for clinical diagnosis. Interventional surgery is the main treatment method. A successful case of interventional embolization of ruptured accessory hepatic aneurysm in our hospital was reported. The accessory hepatic artery variation of this patient belongs to Michels type 4. The bleeding site of the variant artery was identified by CTA and digital subtraction angiography. Satisfactory results were obtained after interventional embolization and follow-up.
