Recognition of supraduodenal artery from hepatic artery is essential to avoid untoward complications at HAIC: two cases

摘要

Supraduodenal artery (SDA) supplies the proximal duodenum, which originates most commonly from gastroduodenal artery (GDA), followed by common and proper hepatic artery. Origination from left hepatic artery (LHA) is relatively rare and only few articles have addressed this anatomic variation. Recognition of such an aberrant artery and proper coiling before liver-directed therapy are essential to prevent non-target organ injury. Herein, we report two rare cases of SDA that originated from the LHA.
