PECULIARITIES OF THE STRUCTURAL ORGANIZATION OF THE ARTERIAL SUPPLY IN LIVER

Abstract

Aim. The aim of the study was to establish general patterns and individual anatomical variability of the hepatic arterial supply. Material and Methods. 150 multispiral computed tomography scans were examined. Results and Discussion. Our study revealed new variants and features of the structural organization of the hepatic arterial supply: a) a significant amount (25.2%) of additional arteries in the right lobe, in the left lobe - 4.7%, both lobes - 0.7%; b) trifurcation of the proper hepatic artery in the hilus of liver: in addition to the right and left branches, there was an artery to the quadrate lobe of liver, from which in turn departed a branch to the lesser curvature of the stomach; c) the length of the common hepatic artery depends on the shape of the duodenum: short artery (5.2±0.37 mm) - in its vertical form (p<0.0001); long (27±0.3 mm) - in horizontal (p<0.0001); intermediate length (7.1±0.3 mm) - in horseshoe-shaped (p<0.0001) form; d) the first hepatic segment is the most variable depending on the number of arteries (from 4 to 5 arteries in 19.2%) (p<0.05). Conclusions. Presence of the intra and intersistemic anastomoses of pancreatic arteries influences the outcome after surgical treatment of pancreatic diseases and should be carefully studied during preoperative examination.
