The importance of an Aberrant Left Hepatic Artery (ALHA), so-called Hyrtl’s artery.

Summary/Abstract: Knowledge of anatomical variants in hepatic vascular structures is obligatory in surgical practice. The purpose of this study is to describe anatomic variations in the Left Hepatic Artery (LHA). In ~60% of cases, LHA is a branch of the proper hepatic artery. The main anatomical variant is an Aberrant Left Hepatic Artery (ALHA) which stems from the Left Gastric Artery, also known as Hyrtl’s artery. The proper identification of ALHA is of importance in the planning and performance of all surgical procedures in the upper abdomen.
