Aim: The aim of the study was to map the morphometry and variability of a partof the abdominal aorta and its branches - the coeliac artery (AC), the cranialmesenteric artery (AMC) and both renal arteries (ARS, ARD).

Methods: CT scans of 13 animals ((7 XY, 6 XX), weigh 28-33 kg, Přešticeblack-pied breed) were evaluated. Measurements were performed in multiplanarreconstructions (MPR), slice thickness 0.8 mm. The transverse diameter (P) ofaorta (Ao), AC, AMC and ARs at the point of separation P Ao(X), the exit angle(ÚO) including, were assessed.

Results: Aorta narrowed caudally, in the segment between the AC and AR from1.1 cm to 0.9 cm. The largest branch was the cranial mesenteric artery. Theaverage values of the branches root lumen diameter P (X) were: P (AC) = 0.6 cm,P (AMC) = 0.7 cm, P (ARD, ARS) = 0.5 cm. The branches departed in a caudallysharp angle: ÚO (AC) = 67.9°, ÚO (AMC) = 75.8°, ÚO (ARD) = 64.4°,ÚO (ARS) = 72.2°. Moderately strong variability of the exit angle of the AC,and the ARS was demonstrated (coefficient of variation > 30, standarddeviation > 20°). 70% of the renal arteries (N = 9) showed right-leftasymmetry and exited between L2-3. In females, the right renal artery waswider (p = 0.007).

Conclusions: Our results map a part of the abdominal arteries of the domesticpig, the Přeštice black-pied breed (N = 13, both sexes, weigh 28-33 kg). Weanticipate their use for the preclinical studies designing, the surgical andimaging methods training in the field of vascular surgery.
