The umbilical artery is a paired artery (with one for each half of the body) that is found in the abdominal and pelvic regions. In the fetus, it extends into the umbilical cord. The umbilical arteries supply deoxygenated blood from the fetus to the placenta. There are usually two umbilical arteries present together with one umbilical vein in the umbilical cord. The umbilical arteries surround the urinary bladder and then carry all the deoxygenated blood out of the fetus through the umbilical cord. Inside the placenta, the umbilical arteries connect with each other at a distance of approximately 5 mm from the cord insertion in what is called the Hyrtl anastomosis. Subsequently, they branch into chorionic arteries or intraplacental fetal arteries. The umbilical arteries are actually the latter of the internal iliac arteries (anterior division of) that supply the hind limbs with blood and nutrients in the fetus. The umbilical arteries are one of two arteries in the human body, that carry ...
The 102 fetuses diagnosed by ultrasound to be asymmetrically growth-retarded had blood flow velocity waveforms of the umbilical artery studied. Sixty-two cases had normal blood flow, 28 had abnormal blood flow but with present end-diastolic flow, 8 had absent end-diastolic flow, and 4 had reversal of end-diastolic flow. Comparison was made between the blood flow status and other biophysical methods of antenatal surveillance and perinatal outcome. There is a strong correlation between abnormal blood flow and abnormalities detected by other biophysical methods of antenatal surveillance. Our study shows that fetuses with severe blood flow impairment tend to be more severely growth-retarded and to be delivered earlier. Our results also show abnormal blood flow to be associated with a poor perinatal outcome. Those fetuses with severe impairment of blood flow suffered a high incidence of operative delivery for fetal distress, acidosis at birth, perinatal mortality and morbidity. The association ...
INTRODUCTION: Serum gamma glutamyl transferase (GGT), produced and released mostly from the liver and bile duct, is an enzyme involved in response to oxidative stress, and has been used as a maker for prediction of cardiovascular events. Umbilical artery blood flow resistance index, e.g., the systolic/diastolic ratio (S/D ratio) as determined by ultrasound, has been used to assess the fetal intrauterine conditions. While changes of GGT and S/D ratio in preeclampsia are found to be associated with the risk for adverse perinatal outcome, the potential value of combined use of the two measurements for the prediction of adverse perinatal outcome has not been determined ...
BACKGROUND: Reference values for umbilical artery Doppler indices are used clinically to assess fetal wellbeing. However, many studies that have produced reference charts have important methodological limitations, and these result in significant heterogeneity of reported reference ranges. OBJECTIVES: To produce international gestational age-specific centiles for umbilical artery Doppler indices based on longitudinal data and the same rigorous methodology used in the original Fetal Growth Longitudinal Study (FGLS) of the INTERGROWTH-21st Project. STUDY DESIGN: In Phase II of the INTERGROWTH-21st Project (the INTERBIO-21st Study), we prospectively continued enrolling pregnant women according to the same protocol from three of the original populations in Pelotas (Brazil), Nairobi (Kenya) and Oxford (UK) that had participated in FGLS. Women with a singleton pregnancy were recruited at |14 weeks gestation, confirmed by ultrasound measurement of crown-rump length, and then underwent standardized ultrasound
Homocysteinemia is a major and independent risk factor for vascular disease. Oxidative stress is a possible mechanism for homocysteine (HCY)-induced vascular disease. Herein, we evaluated the antioxidant property of melatonin (MLT) in relation to the vasoconstrictive effect of HCY on the human umbilical artery. Helical umbilical arterial strips without endothelium were obtained at elective Cesarean delivery near term. Changes in potassium chloride (KCl)-induced vasoconstriction were measured. Arterial strips were treated with HCY (10 or 100 microM) plus FeSO(4) (10 microM) alone or pretreated with a hydroxyl radical ((*)OH) scavenger, mannitol (20 mM), or MLT (1 or 10 microM). The effect of HCY on the response of arterial strips to external calcium (Ca(2+)) in the presence of KCl (20 mM) was determined. HCY plus FeSO(4) potentiated KCl-induced vasoconstriction in a concentration-dependent manner; pretreatment with mannitol significantly reduced this vasospastic effect. HCY (100 microM) significantly
Delayed cord clamping for at least 60 s in both term and preterm babies is a major recent change in clinical care. Delayed cord clamping has several effects on other possible interventions. One of these is the effect of delayed cord clamping on umbilical artery gas analysis. When indicated, umbilical artery gas analysis can safely be done either with early cord clamping or, probably most of the times it is necessary, during delayed cord clamping with the cord still unclamped. Paired blood samples (one from the umbilical artery and one from the umbilical vein) can be taken from the pulsating and unclamped cord, immediately after birth, during delayed cord clamping, without any effect on either the accuracy of umbilical artery gas analysis or the transfusion of blood through delayed cord clamping ...
Experiments on perfused segments or isolated rings of human umbilical artery showed that the magnitude of their contraction in response to bradykinin, epinephrine, or serotonin depended on the Po2 of the perfusing or bathing solution. Constriction to bradykinin varied directly with the O2 tension and was greatest when the Po2 was approximately that of umbilical arterial blood during the transition from the fetal to the neonatal period. Catecholamine beta-receptors were not demonstrated (not present or not functional) in the umbilical artery, since there was no vascular response to either isoproterenol or to propranolol. Alpha-receptors were not required for O2 or bradykinin constriction since these agents constricted the umbilical artery after enough phentolamine had been given to block constriction by norepinephrine. Because of the interaction between O2 and vasoconstrictor agents the O2 environment of umbilical vessels must be rigidly controlled in experiments measuring vascular reactivity. ...
I dont think so, although they might be able to guess that the placenta was rather more ischemic if certain patterns turned up in the waveform -- depending on how the signal bounces back, you might be able to pick up dead areas, but I dont know. Ischaemic areas are hard, because they turn up in a whole lot of pregnancies that go very well. The only thing to say about them is something like "perhaps you are more sensitive to ischaemic areas than other women for some reason", which really is just a fancy way of saying "we have no idea... but there is no other obvious reason why you get PE!" ...
The flow velocity wave forms generated by Doppler ultrasound examination of the umbilical artery were correlated with feto-placental blood flow and numerically expressed as a ratio between the systolic (A) and the end-diastolic point (B). The technique is non-invasive and simple to perform. A cohort analytical study was done to see whether useful information could be obtained from the A/B ratio that could help in the management of patients with severe proteinuric hypertension. Fifty patients with severe proteinuric hypertension at less than 34 weeks gestation were studied and serial Doppler ultrasound examinations of the umbilical artery were performed. No ultrasound results were made available to the clinician. An A/B ratio of 6 or greater was regarded as increased. Twenty-eight of the patients had an increased A/B ratio; in this group these 14 infants were small for gestational age, 14 developed late decelerations and there were 12 perinatal deaths. The remaining 22 patients had an A/B ratio ...

AIM OF THE STUDY: Determination of correlation between Doppler parametersin the evaluation of fetal state and biochemical and clinical determinants of birth status of the newborn.MATERIAL: 30 full-term pregnancies. METHODS: Doppler parameters were determined in maternal vessels (uterineand arcuate arteries), fetal vessels (middle cerebral arteries, renal artery and descending aorta) andin umbilical arteries and veins. Levels of uric acid, xanthine and hypoxanthine, which reflect oxygendeficiency, were assessed in amniotic fluid by means of HPLC method. Furthermore, clinical conditionof a newborn (rating according to the Apgar scoring system), pH-metry and gasometry in umbilical bloodwere assessed. RESULTS: Significant correlation between determinants of fetal and neonatal conditionand Doppler parameters were determined, that is: between uric acid concentration and blood flow in fetalcerebral arteries, between base excess, pH and blood flow in umbilical vessels, between clinical examinationof ...

Although UCM is becoming increasingly popular at the delivery of preterm infants, little is known about the acute physiological effects of UCM and how it influences the cardiovascular transition after birth. We have now quantified the blood transfer achieved by two different UCM strategies and compared the physiological changes associated with UCM with immediate UCC and PBCC strategies. We found that both UCM strategies caused large fluctuations in mean arterial blood pressures and cerebral blood flows that are similar to clamping the UC multiple times. While it is commonly assumed that UCM enhances blood transfer to the fetus, we found that only UCMwPR produced a net blood volume transfer towards the fetus. The measured transfer of approximately 8.8 mL/kg (IQR 8-10 mL/kg) of blood during UCMwPR likely represents half the volume the lamb received, as we only measured blood flow in one umbilical vein and one umbilical artery. The volume transfused via UCMwPR is therefore consistent with the ...

Helpful, trusted answers from doctors: Dr. Scott on fetal doppler heart rate monitor: Monitoring a fetus by fetal hr, ultrasound or the expectant womans perception of activity is important. No one test can tell us everything we need to know, but together they can tell us which babies might be better off delivered. If a baby is near term and the testing is worrisome then obstetric specialists or subspecialists might deliver. But conditions can change. Plus every case is different.

Introduction Middle cerebral artery (MCA) and umbilical artery (UA) Doppler blood flow pulsatility indices (PIs) and MCA peak systolic velocity (PSV) are essential variables for clinically evaluating fetal well-being. Here we examined how a maternal meal influenced these Doppler blood flow velocity variables. Methods This prospective cohort study included 89 healthy Caucasian women with normal singleton pregnancies (median age, 32 years). Measurements were performed at gestational weeks 30 and 36, representing the start and near the end of the energy-depositing period. Measured variables included the MCA-PI, UA-PI, fetal heart rate (FHR) and MCA-PSV. The cerebroplacental ratio (CPR) was calculated as the ratio of MCA-PI to UA-PI. The first examination was performed in the fasting state at 08:30 a.m. Then participants ate a standard breakfast (approximate caloric intake, 400kcal), and the examination was repeated ~105 min after the meal. Results Without adjustment for FHR, fetal MCA-PI decreased ...

Initially, I was reluctant to get involved because the patient reported that the bleeding came from deep inside her umbilicus and that in the past the surgeons in the hospital complained about how difficult it was to gain access to the site of the bleeding and to place sutures. I advised the patient to keep firm pressure on her umbilicus and to call an ambulance. However, after a little while I decided to call the patient back because I knew that a trip to the hospital would be a major ordeal for her because of her disability. I packed my medical supplies and instruments and went to the patients home. Upon arrival at the patients bedside I noticed that the gauze pads that were used to stop the bleeding were soaked in blood and that there was a pool of blood next to the bed. As soon as the gauze pads were removed I saw the blood squirting out of the umbilical artery. This made it difficult to have a clear surgical field. Fortunately, within a short time I was able to place two sutures around ...

Despite the perceived importance of umbilical cord care after birth for potentially reducing the incidence of umbilical infections and possible subsequent umbilical hernias, very few randomized trials have evaluated umbilical cord care and antiseptic use in production-animal settings. In one epidemiological study using dairy calves,9 risk of calf mortality was significantly lower following use of chlorhexidine than after use of iodine or no cord care, while iodine tended to increase mortality risk. In a more recent study, Robinson et al10 reported no differences between umbilical antiseptic treatments (7% iodine, 10% trisodium citrate, 4% chlorhexidine, and 1000 mmol per L chlorine) for enhancing healing or reducing the incidence of infection in Jersey calves in a clean, dry environment. However, an important consideration when comparing across species is that calves have a much larger umbilical cord than do piglets, which may affect both healing time and risk of infection.. However, the ...
Severe intrauterine growth restriction (IUGR) is recognised to be a major cause of perinatal morbidity and mortality. Identifying the fetus that is truly growth restricted and therefore compromised, from the one that is simply genetically small and not at risk is difficult. Recent work using umbilical artery (UA) Doppler waveform studies have shown that a reduction in the diastolic component of the UA Doppler waveform correlates strongly with poor perinatal outcome. Since this technique can be used to reliably distinguish the truly growth restricted fetus at risk, it is imperative, if we are to understand the pathophysiology of severe IUGR, that the mechanisms by which abnormal Doppler waveforms arise is established. The elaboration pattern of blood vessels within stem villi from IUGR and gestationally age- matched control placentas, was first evaluated by measuring the diameter of 600 vessel profiles, identified by the antibody anti-a smooth muscle actin, within stem villi from randomly chosen ...
Introduction: Growth factors can stimulate angiogenesis, which describes the sprouting of new capillaries from endothelial cells. So far, the transcriptional regulation of endothelial cell function during this process is only incompletely understood. While high expression of the transcription factor Gata6 was previously reported in human umbilical vein endothelial cells (HUVECs), its importance for angiogenic function and endothelial cell survival remained unknown.. Results: We detected Gata6 mRNA and protein expression in HUVECs, human umbilical artery endothelial cells (HUAECs), human cardiac microvascular cells (HCMECs) and also in vascular endothelial cells in mouse tissues in vivo. Stimulation of HUVECs with a growth factor cocktail (containing FCS, EGF and bFGF), led to translocation of Gata6 to the nucleus, enhanced chromatin binding at the promoter region of endothelial Gata target genes (Pecam1, EDN-1 and NOS3; ChIP-assay) and enhanced Gata mediated transcriptional activation ...

Adhesion of platelets to the vessel wall is the first step in hemostasis and thrombosis. This makes it an attractive target for the development of an antithrombotic agent. Most drugs interfering with platelet function do not affect its adhesion. An approach based on functional domains of adhesive ligands or receptors should therefore be considered seriously. In this article, we report on the antiadhesive profile of VCL, a recombinant fragment of vWF expressed in E coli and purified to homogeneity. This fragment, the activity of which was first established in aggregation studies with ristocetin and botrocetin, was found to be a potent inhibitor of platelet adhesion to subendothelium of umbilical arteries at 2600 s−1.24 We studied the adhesion to the ECM of cultured endothelial cells. Previously, we have demonstrated that the matrix of cultured human umbilical endothelial cells may serve as a good model for the subendothelium.41 The inhibition was shear rate dependent, with a more potent ...
DISCUSSION: The newborn infant has a relatively elevated pulmonary artery pressure and shunts a significant amount of unoxygenated blood through the foramen ovale and patent ductus arteriosus. The normal PaO 2 below the ductus, as measured through an umbilical artery catheter, would be between 60 and 80 mm. Hg. Surfactant levels do not approach normal until after the 34th week of gestation, when enzyme levels in the surfactant pathway mature. Amniocentesis is performed to measure the lethicin-to-sphingomyelin ratio (L:S ratio) and determine whether maturation has occurred. Fluid requirements in the premature infant are between 140 and 150 ml. per kg. per day in comparison with those of the normal neonate in whom 80 ml. per kg. per day would be adequate. Increased insensible losses and the need for overhead warmers play a role in this increase. Axillary or skin probe temperature monitoring is more accurate than the rectal temperature in the neonate. The rectal temperature is not a good indicator ...

This ultrasound was the 1/2 way one during the pregnancy where they look at all of his little organs and parts and make sure hes developing normally. He had his little hands and arms up by his face so I couldnt see his face though...and he never moved them away! After the ultrasound tech finished a doc looked at the photos and came in to talk to me. He said the babys cord is a two vessel cord instead of a three/ he has a single umbilical artery instead of two arteries. This happens in about 1% of pregnancys. The doctor called it a "soft defect marker" :( He then proceeded to tell me that there were NO other signs of defects, specifically hes right where he should be growth wise and his heart and kidneys look good.The Doc also said that it will be easier for the cord to get wrapped around things or pinched in the womb in the third trimester just because its smaller. He told me not to worry but said theyd keep a closer watch of him. Needless to say.... Id had nightmares all night about ...
