Umbilical Artery Catheterization in Neonates
Archives of Pediatrics & Adolescent Medicine, 1971A method presented for placement and anchorage of umbilical artery catheters utilizes the following formula: catheter length from the abdominal wall level = 0.33 × heel-crown length. An argument for positioning the catheter tip between T-6 and T-10 is also presented. It is believed that this formula will facilitate the uses of, and decrease the hazards

Although a variety of neonatal arteriovenous fistulas have been described, including some between persistent fetal structures,1,2this is the first observation of an umbilical artery-vein fistula. This fistula was probably produced by an indwelling umbilical vein catheter.

Umbilical artery blood flows among pregnancies with single umbilical artery
The Journal of Maternal-Fetal & Neonatal Medicine, 2015We read with interest the article by Baron et al. [1] that the lower impedance with the same peak systolic velocity level was observed in the umbilical artery of patients with a single umbilical ar...

Vesico-umbilical fistula: A complication of umbilical artery cutdown
Journal of Pediatric Surgery, 1980A vesico-umbilical fistula occurred following cut down for catheterization of the umbilical artery in a premature infant; a previously unreported complication. Knowledge of the variations in anatomical structure of the urachus and umbilical arteries at birth will help to prevent this complication.

Spontaneous haematoma of the umbilical cord with a single umbilical artery
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1996A rare example of the partial rupture of the umbilical vein resulting in a cord haematoma is reported. CTG alterations made possible to anticipate the deterioration of the foetal condition and a healthy infant was delivered by emergency caesarean section.

Umbilical artery sinus Rare cause of umbilical drainage
Urology, 1982Abstract Only 1 previous report was found of a persistent umbilical artery causing sinus tract formation and umbilical drainage. Radiologic studies confirming the anterolateral direction of the sinus allows preoperative diagnosis.

Although numerous reports are available concerning infants who have single umbilical artery, there are no studies that correlate the incidence of congenital malformations or prognosis of such infants with the presence or absence of an atrophied artery in their associated umbilical cords.

Genesis of single umbilical artery
American Journal of Obstetrics and Gynecology, 1970Abstract It is generally accepted that a single umbilical artery in the cord is the result of either aplasia or atrophy of the missing vessel although evidence seemingly supporting such mechanisms is seldom found. In the course of studying the development of the umbilical arteries in young human embryos another possible cause became apparent.

Umbilical Artery Waveforms in Triplet Pregnancy
Survey of Anesthesiology, 1990Twenty patients with triplet pregnancies underwent continuous-wave Doppler ultrasound umbilical artery waveform studies as part of a multiple-pregnancy surveillance program. One or more infants was small for gestational age in nine of these triplet pregnancies. In all of these cases, at least one abnormal umbilical artery velocity waveform was present.

We retrospectively reviewed the records of 56,919 infants born from 1966 through 1986 to determine the incidence, significance, and possible associations of single umbilical artery (SUA). One hundred fifty-nine infants were affected. The sex distribution was approximately equal. Fourteen infants (8.8%) were twins who were discordant for SUA.
