Varicosity and Pregnancy Induced Blood Flow Changes in the Cranial Tibial Vein in Buffaloes: B-mode and Doppler Ultrasound Study
نویسندگان
چکیده
The study was aimed to assess the effect of varicosity and pregnancy on the blood flow parameters in 22 cranial tibial veins of 17 buffaloes using B-mode and Doppler ultrasonography. Out of these, five buffaloes were suffering from unilateral hind limb varicosity and 12 were clinically healthy non-pregnant (n=6) or in advanced stages of pregnancy (n=6). The study highlights a significant increase in the Doppler blood flow parameters of varicosity affected veins in comparison to clinically healthy cranial tibial veins, with highest percentage change in volume flow/minute. A significant lower vessel diameter and end diastole velocity of the cranial tibial vein was also recorded in healthy advanced pregnant compared to that of healthy non-pregnant buffaloes.

Accurate assessment of gestational age, fetal growth, and the detection of fetal and placental abnormalities are major benefits of sonography. Color Doppler can be used to assist in the identification of vascular architecture, detection of vascular pathology and visualization of blood flow changes associated with physiologic processes and disease states. The clinical applications of obstetrical...

Introduction: Arterial stiffness is an important predictor of cardiovascular risk. Several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. Since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...

Background In patients with abnormal uterine bleeding, transvaginal ultrasound (TVS) is the first-line diagnostic approach to exclude endometrial pathology. If a thickened endometrium suggests endometrial pathology, sonohysterography, office hysteroscopy or dilatation and curettage are the second-line tests preferred, depending on availability and on the suspected pathology, to exclude malignan...

It has been shown that inflammation reduces the effectiveness of sympathetic nerves in the regulation of knee joint blood flow, and the joint vascular- ß adrenoceptors are changed due to acute inflammation from a majority of ß-1 to an equality of ß-1 and ß-2 receptors.. To investigate the role of sympathetic nerves in nerve induced vasoconstriction and changes in joint vascular ß-adrenoceptors ...

Real-time B-mode ultrasonography was combined with a pulsed Doppler ultrasound technique for transcutaneous measurement of human fetal blood flow in the aorta and intra-abdominal part of the umbilical vein. The target vessel was located and its diameter measured in the two-dimensional real-time image. The pulsed Doppler transducer was attached to the real-time transducer at a fixed angle. By pr...
