Introduction: Hepatic artery pseudoaneurysm (HAPA) was a rare but lethal disease. Surgery, recommended as the main choi- ce for the management of HAPA in the past, often associated with high rates of bleeding recurrence and mortality. Recently, tran- scatheter arterial embolization (TAE) has been gradually applied in the treatment of HAPA. However, these studies were mostly case reports and with less efficacy evaluation, the main purpose of this study was to provide more evidence of TAE on the effect of HAPA.
Materials and methods: Six HAPA patients with recurrent gastrointestinal or abdominal bleeding were enrolled in this study. Digital subtraction angiography and embolization treatment were performed, and the treatment efficacy was investigated. Of 6 patients, 4 had intrahepatic HAPA and 2 had extrahepatic HAPA.
Results: Two patients had major postoperative bleeding after traumatic hepatic rupture repair, and 4 had surgical postoperati- ve bleeding. Five patients had no secondary bleeding after the first embolization; 1 intrahepatic HAPA patient exhibited major blee- ding 10 days after intrahepatic embolization, but bleeding stopped after the second embolization. One patient died of liver failure 1 day after the embolization.
Conclusions: Angiographic diagnosis and arterial coil embolization achieved a good result of HAPA treatment, which indica- ted that TAE was a safe and feasible treatment of HAPA.
