Doppler velocity measurement has been extensively applied in prenatal diagnosis for more than two decades. Blood flow in numerous vessels has been investigated to predict fetal condition, especially in the umbilical artery [1–7]. Histopathologic studies suggest that abnormal umbilical artery Doppler velocimetry is correlated with a pathologic lesion of the placenta characterized by obliteration...

Understanding anatomical variations can help physicians achieve better results in clinical practice. During routine dissection, we found variations in the branches of Internal Iliac Artery (IIA) of a 65-year-old Iranian female cadaver. The IIA ended by dividing to an unusual smaller anterior and a greater posterior trunk which was branched to the inferior gluteal arteries. Both pelvis and the u...

Background: Arterial catheters are frequently needed to optimize the intensive care in sick newborn. Umbilical Catheters (UAC) is more popular than peripheral arterial catheterization. They utilized provide continuous accurate blood pressure monitoring, frequent assessment of gas exchange efficiency, sampling and rarely for transfusion. may be used emergencies infuse fluids or medications absen...

PURPOSE To explore the effect of pulsatile flow in the decellularization process of small blood vessels. METHODS A total of 30 human umbilical cords were used in the current study. The umbilical cords were flushed with 0.25% trypsin/0.01% EDTA for 30 minutes, followed by treatment with 1% sodium dodecyl sulfate sodium dodecyl sulfate for 3 hours. The effectiveness of decellularization on the ...

Background: To evaluate the effect of oxytocin on blood circulation of fetus and uterus by Doppler ultrasound. Materials and Methods: Forty six pregnant women were assigned to receive for indication of delivery intravenous oxytocin. Doppler velocitometry before and after administration of oxytocin for umbilical,middle cerebral artery and uterine artery were performed, and Pulsatility index (PI)...

OBJECTIVES Determination of gestational age-related modulations in fetal heart rate and descending aorta blood flow velocity in the early human fetus and comparison of aortic variability data with data obtained from the umbilical artery. It is hypothesized that these modulations present in the umbilical artery also occur in the descending aorta. METHODS Doppler studies of descending aorta vel...

Background: Abnormal umbilical cord pH can be indicated a distress imposed of newborn and can also be useful in determining the prognosis of the newborn. There are different views about the effect of the neonatal delivery method on the blood gas analysis of the umbilical artery. This study aimed to determine the effect of the method of delivery on umbilical artery pH. Methods: In this Cross-Sec...
