The Value of Transcatheter Embolization in Hepatic Artery pseudoaneuryms

Objective To evaluate the therapeutic value and affect for liver function of transcatheter embolization in patient with hepatic artery pseudoaneuryms. Materials and Methods 8 patients with hepatic artery pseudoaneuryms were performed to selective angiography and treated with transcatheter embolization. 3 to 60 months was followed up to observe clinical effect and liver function after transcatheter embolization. Results Angiography clearly showed location, formation or fending artery of pseudoaneurym in 8 cases. The pseudoaneuryms located at extrahepatic area in 4 cases and located at intrahepatic area in 4 cases. Repeated angiography depicted complete obliteration of the pseudoaneuryms after embolization in all patients. The patients with ruptured pseudoaneuryms active bleeding were stopped immediately after embolization. 7 patients who were embolized by use of coils or microciols were not reoccurred of pseudoaneuryms or active bleeding. 1 patient who was embolized by use of gelatin sponge occurred rebleeding 3 days after the embolization. Pseudoaneuryms disappeared in 4 cases. The pseudoaneuryms became shrunk in 3 cases. 2 patients had a temporary increase of transaminases. Liver function recovered to normal in one week after embolization in 2 cases. The liver function was normal in 4 cases. Conclusion Coils embolization is a safe and effective treatment for the patients with hepatic artery pseudoaneuryms. Liver function is not significant influenced after selective hepatic artery embolization.
