The association of iSUA to adverse outcome of pregnancy has not been consistently reported and whether iSUA carries increased risk of third. Recommendations regarding counseling and man-agement in cases of an isolated single umbilical artery Echocardiography Normal.
The incidence of chromosomal abnormalities was 0 in the isolated SUA group 37 in those with one.
Isolated single umbilical artery. To evaluate if isolated single umbilical artery SUA diagnosed on second-trimester ultrasound has an independent risk association with adverse pregnancy outcomes. We compared 136 singleton pregnancies with isolated SUA with 500 consecutive singleton pregnancies with a three-vessel cord 3 VC. Pregnancies complicated by chromosomal abnormalities and other.
To review our 25-year experience with a single umbilical artery and fetal echocardiography to estimate the need for this test in cases of an isolated single umbilical artery. We conducted a retrospective review of 436 patients with a diagnosis of a single umbilical artery at our institution between 1990 and 2015. Two hundred eighty-eight women had both an anatomic survey.
A single umbilical artery SUA is found in about 05 of pregnancies and is associated with chromosomal defects and malformations of all major organ systems 1 2. In previous studies on a combined total of 1038 cases of SUA diagnosed prenatally the prevalence of fetal abnormalities was 336 Table 1 3-15. Consequently the prenatal diagnosis of SUA should motivate the sonographer.
A single umbilical artery SUA is found in about 05 of pregnancies and is associated with chromosomal defects and malformations of all major organ systems12In previousstudies on a combined total of1038 casesof SUA diagnosed prenatally the prevalence of fetal abnormalities was 336 Table 1315. To determine whether isolated single umbilical artery iSUA even absent identifiable genitourinary GU abnormalities increases the risk of GU infection during childhood. Retrospective population-based comparison of fetuses with iSUA versus normal three-vessel cords.
Fetuses with growth restriction prematurity multiple gestations and anatomical or. Isolated SUA was associated with a higher rate of CS due to NRFHR 55 vs 1 p 002 small for gestational age SGA 143 vs 49 p 0009 lower birth weight and a higher rate of composite adverse outcome 209 vs 88 p 0005. On multivariable analysis isolated SUA was independently associated with an increased risk for composite adverse outcome OR 234 95 CI.
To investigate whether children born with isolated single umbilical artery iSUA at term are at an increased risk for long-term pediatric hospitalizations due to respiratory morbidity. A population-based cohort study compared the incidence of long-term pediatric hospitalizations due to respiratory morbidity in children born with and without iSUA at term. The absence of one umbilical artery which represents the most common anatomical abnormality of the umbilical cord is found in 0220 of deliveries.
The pathogenesis of this condition known as single umbilical artery SUA is uncertain. Aplasia or atrophy of the missing vessel has been suggested in the etiology. Cies with an isolated single umbilical artery do not need to have fetal echocardiography when the views of the 4-chamber heart and outflow tracts are normal at the time of theanatomicsurvey.
Recommendations regarding counseling and man-agement in cases of an isolated single umbilical artery Echocardiography Normal. Isolated single umbilical artery and fetal karyotype T. NICOLAIDES Harris Birthright Research Centre for Fetal Medicine Kings College Hospital Medical School London UK KEYWORDS.
We sought to determine the rate of adverse perinatal outcomes in pregnancies diagnosed with an isolated single umbilical artery SUA. We performed a retrospective review comparing 68 pregnancies with an isolated SUA to 68 pregnancies with a three-vessel cord 3VC. Pregnancies with structural or karyotypic anomalies were excluded.
Gestational age at delivery birth weight SGA rate ponderal. The presence of isolated single umbilical artery SUA in infants has been associated with an increased risk of occult renal malformations. However the need for routine postnatal renal imaging of such infants especially in an era of now routine antenatal fetal sonography is controversial.
There were 643 cases with SUA including 424 659 where the condition was isolated 133 207 with one major fetal defect and 86 134 with multiple defects. The incidence of chromosomal abnormalities was 0 in the isolated SUA group 37 in those with one. The aim of this study was to evaluate the association between prenatally diagnosed isolated single umbilical artery iSUA and perinatal outcomes.
We searched Medline Embase the Cochrane Library and KoreaMed from inception to January 2016 with no language or regional restrictions for cohort and case-control studies reporting on the relationship of iSUA and. From Wikipedia the free encyclopedia Occasionally there is only the one single umbilical artery SUA present in the umbilical cord. This is sometimes also called a two-vessel umbilical cord or two-vessel cord.
Approximately this affects between 1 in 100 and 1 in 500 pregnancies making it the most common umbilical abnormality. Isolated single umbilical artery iSUA refers to single umbilical artery cords with no other fetal malformations. The association of iSUA to adverse outcome of pregnancy has not been consistently reported and whether iSUA carries increased risk of third.
In univariable analysis the presence of an isolated single umbilical artery was significantly associated with lower mean birth weight and with a higher frequency of SGA P. Pregnancy-induced hypertension was more common among pregnancies complicated by an isolated single umbilical artery. The incidence of isolated single umbilical artery in twins and adverse pregnancy outcomes.

The normal group was defined as pregnancies with an isolated single umbilical artery and normal 4chamber and outflow tract views. The incomplete group consisted of pregnancies with an incomplete or inadequate cardiac study. If a cardiac anomaly was diagnosed or.
