Hemodinamične spremembe maternične arterije pri kobilah z različnimi patologijami maternice

Cysts, fluid accumulation, inflammatory changes and tumors are common uterine pathologies in mares. It was aimed to investigate the change of uterine hemody­namics in mares according to uterine pathologies (endometritis or intrauterine cysts). The study contained 28 mares and the groups formed as 9 gynaecologically healthy diestrus mares (Group H), 9 mares with endometritis (Group E) and 10 mares with intra­uterine cyst (Group C). The mean uterine diameter (UD) in Group H (2.29±0.18 cm) was significantly lower than in Group C (2.97±0.19 cm) (P<0.05) and in Group E (3.47±0.29 cm) (P<0.01). The diameters of the intrauterine cysts ranged between 0.51 cm and 1.83 cm in Group C. The highest diameter of the uterine artery (UA) was observed in Group E. Hemodynamic indices of UA (PI and RI) in Group E were not significantly different from those in Group C (P>0.05). However, PI and RI values in Group H were significantly lower than both in Group E and Group C (P<0.001). The UA waveform in Group E had an early diastolic notch while systolic notches and small diastolic peaks were observed in the UA waveforms of the mares in group C. Doppler USG is considered as a useful tool to analyze the waveform and hemodynamics of the UA related to the different pathologies (cyst or endometritis). It was concluded that not only Doppler indices but also character­istics of the waveforms of the UA should be evaluated to understand the hemodynamic effect of the uterine pathologies.
