Abstract
Domestic pigs were frequently used in training centers for residents and students in medicine for the stenting procedures at the level of renal arteries. On 12 domestic pigs (all male) with an average weight of 34 kg (30.0-39.9 kg), were analysed the morphological parameters of femoro-iliaco-aorto-renal arterial system. An analysis of the pelvic segment length (I-II-III) and abdominal (IV), shows almost perfect equality of the lengths of the two segments on the right (76.26 ± 5.30 mm / 76.21 ± 4.51 mm) and a mean difference of 1.25 mm in favour of segment IV (abdominal) (75.53 ± 5.10 mm / 76.78 ± 4.44 mm), a difference that correlate with left renal artery cranial origin. Pelvic diameter portions of femoro-iliac arterial axis increase linear in average by 10% per segment (from 3.99 ± 0.40 mm ± 4.89 in segment I at 4.89±0.33 mm in segment III). Increasing the diameter from the segment III to segment IV is approximately of 30%. The diameter of the proximal part of renal artery (3.46 ± 0.36 mm) on the studied material is smaller than the diameter of the proximal part of the external femoral artery (segment I) (3.99 ± 0.40 mm), making it easy retrograde catheterisation of femoro-iliac-aorto-renal arterial axis. Knowledge of the morphological parameters of femoro-iliaco-aortic arterial axis and their evolution in correlation with the weight of laboratory animals -domestic pigs- favours the achievement in good conditions to arterial catheterization for proximal renal artery stenting.
