Digital analysis of the dynamics of the arterial supply to the human foetal kidneys.
Variations in the renal arteries in human individuals and foetuses have already been well studied. Contemporary trends in visualisation techniques focus on the evaluation of the dynamic parameters of blood flow in the vessels (speed, pulsatility, resistance). Most of these data have been obtained by the means of Doppler ultrasound (Fig. 1, 2). The authors have not found any anatomical database containing information about variability in the volume of the foetal renal arteries. The aim of the study is to design a database for variation in foetal renal artery volume in relation to foetal age and sex. The material consisted of digital images of the renal arteries filled with LBS-latex taken from 30 foetuses aged 12-19 Hbd. Digital analysis of the arteries was made with a unique form of software. The program is a 2D vector graphic editor using spliced functions of Bezier. Foetal age is estimated according to the last menstrual period and measurement of manual foot length and femur length (FL) as determined by ultrasound.
