CT angiographic study of hepatic arteries variants in Iranian subjects

Abstract

This retrospective study aimed to assess the anatomical variations of hepatic arteries (HAs) in Iranian subjects referred to the Baqiyatallah Hospital (Tehran, Iran) as a reference medical center. The presence of anatomical variations such as hepatic arteries (HA) is approved among different societies. Classification of common patterns and probable variants of HA seems necessary in preoperative precautions of hepatosurgeries. Multidetector computed tomography angiography scans were prepared from the patients referred to the Baqiyatallah Hospital from January 2019 to January 2020. Inclusion and exclusion criteria were assessed, and all patterns of hepatic arterial supply were evaluated in 240 cases based on Michels’ classification of HA. Following the assessment of 240 patients, HA variants with aberrant origin (types of II-VIII) were detected in 55 cases (22.92%). Besides, no patients were reported as types of XI and X variants (n=0). Also, no relationship was found between the HA and gender. Detection of common patterns along with abnormal variations of HA variants is necessary for hepatosurgical procedures. We found that 22.92% of Iranian patients referred to the Baqiyatallah hospital represented HA variation which must be considered in hepatic surgeries.
