PREVALENCE OF HEPATIC ARTERY ATHEROSCLEROSIS AND FACTORS AFFECTING HEPATIC ARTERY ATHEROSCLEROSIS IN PATIENTS WITH ABDOMINAL AORTA ATHEROSCLEROSIS

Backgrounds/Aims: This study aimed to investigate the prevalence of hepatic artery (HA) atherosclerosis and the factors affecting HA atherosclerosis in adults with abdominal aorta (AA) atherosclerosis detected by computed tomography angiography (CTA). Methods: 296 adults with AA atherosclerosis who underwent CTA of the AA for various reasons in 2020 at xxx University Hospital were included in this study. The presence and type of atherosclerosis in the common HA, right, and left HA were evaluated. Celiac trunk anatomy, HA anatomy, presence of left gastric artery (LGA) atherosclerosis, calcium scores of other visceral branches of the AA, and total AA atherosclerosis score were evaluated in all patients. These parameters were compared between patients with and without HA atherosclerosis. Results: HA atherosclerosis was found in 25 cases (8.4%). The most common type of HA atherosclerosis was calcified plaque in the common HA. The mean age of patients with HA atherosclerosis was statistically significantly higher than those without (70±7.67 vs 66±9.3, p= 0.041). There was a statistically significant correlation between HA anatomy and HA atherosclerosis (p= 0.034). Post hoc analyses revealed that HA atherosclerosis was more frequent in patients with type 2 and type 3 HA anatomy (p values 0.027 and 0.044, respectively). Prevalence of the LGA atherosclerosis was significantly higher in patients with HA atherosclerosis than those without (12% vs 0.3%, p= 0.002). Total renal artery (RA) calcium score, superior mesenteric artery (SMA) calcium score, splenic artery (SA) calcium score, AA total atherosclerosis score, and total iliac artery (IA) calcium score were significantly higher in patients with HA atherosclerosis than in patients without (p values
