Investigation of proper hepatic artery and gastroduodenal artery variations by multidetector computed tomography angiography method

Abstract

Purpose: The purpose of this study is to evaluate the clinical anatomic variations of the proper hepatic artery (PHA) and the gastroduodenal artery (GDA). For this purpose, angiographic images of patients were evaluated.

Materials and methods: We retrospectively reviewed the multiple-detector computed tomography angiography images of 671 patients.

Results: In this retrospective study, 35 different types were identified as associated with PHA and GDA. There were 292 patients (43.52%; 175 females and 117 males) included in normal anatomical classification. Different anatomic variations were detected in 300 patients (44.71%; 129 females and 171 males). In 79 patients, arterial branch follow-up failed. These patients were evaluated as an unidentified group.

Conclusion: We described different vascular variations in the PHAs and GDAs of our patients.
