Abstract

Backround /Aim: The aim of the present study was to evaluate the corpus luteum images of the goats biometric and hemodynamically and to investigate the relationship between corpus luteum CL size and time-dependent changes with luteal arterial resistance during the early pregnancy stage. Material and Methods: For this purpose, 94 B-mode and 63 Pulsed Doppler CL images taken from 21 healthy pregnant goats aged 1-5 years were examined. The mean number of CL, maximum CL diameter mm and the resistance indices RI of the luteal vessels were determined in these images taken by transrectal ultrasonography on 7th, 14th and 21st days of pregnancy. Results: The mean numbers of corpus luteum that can be visualized on days 7th, 14th and 21st of pregnancy were 1.81±0.16; 1.38±0.11 and 1.15±0.08. The mean maximum diameter and luteal blood flow resistance values ​​of luteal tissues were measured as 13.23±0.49 mm / 0.43±0.03; 16.04±0.76 mm / 0.33±0.02 and 16.98±0.41 mm / 0.34±0.02 respectively. It was observed that the mean corpus luteum diameters increased from the first week up to the 21st day P

Gebe keçilerde erken dönem korpus luteum ultrasonografisinin değerlendirilmesi

Abstract

Özbilgi/Amaç: Sunulan araştırmada, keçilerde erken gebelik döneminde korpus luteum görüntülerinin biometrik ve hemodinamik açıdan değerlendirilmesi ve korpus luteumun büyüklüğü ve zamana bağlı değişimin luteal arteriel direnci ile olan ilişkisinin araştırılması amaçlandı. Materyal ve Metot: Bu amaçla, 1-5 yaşlarında 21 sağlıklı gebe keçiden elde edilen toplam 94 adet B-mod ve 63 adet Pulsed Doppler korpus luteum ultrasonografi görüntüsü incelendi. Gebeliğin 7, 14 ve 21. günlerinde transrektal ultrasonografi ile görüntülenebilen ortalama korpus luteum sayısı, maksimum korpus luteum çapı mm ve korpus luteumda perfüzyonu sağlayan damarlara ait rezistans RI değerleri belirlendi. Bulgular: Gebeliğin 7, 14, ve 21. günlerinde ortalama korpus luteum sayıları sırasıyla 1.81±0.16; 1.38±0.11 ve 1.15±0.08 olarak kaydedildi. Luteal dokulara ait ortalama maksimum çap ve luteal kan akım direnç değerleri ise sırasıyla 13.23±0.49 mm / 0.43±0.03; 16.04±0.76 mm / 0.33±0.02; 16.98±0.41 mm / 0.34±0.02 olarak ölçüldü. Ortalama korpus luteum büyüklüklerinin ilk haftadan başlayarak 21. güne kadar arttığı P
