“…In the literature, conditions appear which are traditionally related to UC length, including: -Fetal mobility [18], abnormal cords can be expected when scant space is available for the fetus: for example, in twin gestation, when the uterus is anatomically abnormal; and when chromosomal, muscular or neurological disorders occur in the fetus. Similarly, long cords can be expected in women with 3+ parity [5]. -Genetic component: a difference exists in early vascular development between female and male fetuses [19], consequently, more long cords are anticipated in males [9].…”

“…When UC abnormalities occur they may in turn be associated with spontaneous abortions [1], stillbirths [2,3], unexpected perinatal deaths, neurological alterations and intrauterine anoxia [4]. Length is the UC characteristic most frequently associated with such complications [5]. If the cord is long, cord prolapse, entanglement around the neck of the fetus (or other parts of the body), increased coiling, contrary coiling, true knots, single umbilical artery (SUA) and thrombosis may ensue [5,6].…”

If the cord is long, cord prolapse, entanglement around the neck of the fetus (or other parts of the body), increased coiling, contrary coiling, true knots, single umbilical artery (SUA) and thrombosis may ensue [5,6]. If the cord is short, there is a strong likelihood that severe morphological alterations in the abdomen and limbs of the fetus [7,8], will occur; as well as low APGAR and unsatisfactory fetal state, rupture or bruising of the cord, uterine inversion, placental abruption and fetal descent disorders [9].…”

INTRODUCTION: Umbilical cord (UC) alterations are involved in fetal and neonatal complications, and even deaths. Abnormal length has been recognized as the most important UC feature linked to unfavorable results. However, how can the UC be accurately measured in cases in which there is an overriding need for intravenous intervention, urgent lab samples or segments for stem cell cultivation? METHODS: We performed an observational study to describe our UC length measurement method at the San Ignacio University Hospital (HUSI). RESULTS: All HUSI obstetricians and pediatricians accepted the new rapid cord measurement method; no delays were reported for either maternal or neonatal care. CONCLUSIONS: In light of the association of abnormal UC length to complications, we recommend that complete UC length data be registered. Our new and rapid method allows for any UC intervention to be performed, while at the same time, providing precise UC length data under all circumstances.

“…En condiciones reales de la circulación de un feto, tal afirmación no es certera, ya que se carece de los datos de estas variables (gasto real vs. longitud del cordón umbilical); por tanto, las reflexiones sobre las implicaciones clínicas ya conocidas de las condiciones físicas del cordón umbilical en el gasto cardiaco fetal (9,11,26) se están materializando mediante aproximaciones sucesivas (expansiones de Q).…”

“…La longitud se ha definido como la principal característica del cordón umbilical (9), porque cuando es anormal, tiene graves implicaciones en la salud del feto, en la adaptación del recién nacido y en el pronóstico neonatal (10); no obstante, las características de las que depende siguen siendo un enigma (11). Al revisar bases de datos no se encontró literatura relacionada con el tema, por lo que la aproximación desde la física podría ser novedosa para el estudio de esta estructura.…”

Artículo de reflexión RESUMENIntroducción: el cordón umbilical es una estructura incomprendida a pesar de transportar todo lo que un feto necesita para crecer y subsistir. Cada una de sus características es relevante, y la principal es la longitud, la cual, cuando está alterada, se relaciona con pobre pronóstico neurológico y muerte fetal. Materiales y métodos: con base en la revisión de principios físicos, se proponen fórmulas que podrían explicar la importancia de la longitud del cordón por sus repercusiones hemodinámicas. Resultados: se analizó la circulación fetal desde el corazón hasta la red capilar vellositaria en el plato placentario y, por medio de fórmulas físicas, se plantea la importancia de la longitud del cordón en la perfusión fetal. Conclusiones: las complicaciones clínicas conocidas para la excesiva longitud del cordón umbilical fueron analizadas desde el punto de vista de la física, dejando listas las fórmulas para ser alimentadas Recibido: mayo 26/14 -Aceptado: febrero 9/15 con datos reales provenientes de doppler fetales y mediciones del cordón umbilical. ABSTRACTIntroduction: Despite its role of transporting all the things that a foetus needs to grow and survive, the umbilical cord is still poorly understood. All of its characteristics are relevant, and paramount among them is its length. When abnormal, length is associated with poor neurological prognosis and foetal demise. Materials and methods: Based on a review of physics principles, formulae were proposed in an attempt to explain the importance of umbilical cord length on the basis of its haemodynamic repercussions. Results: Foetal circulation was analysed from the heart to the placental villous capillaries and physics formulae were used to describe the importance of umbilical cord length in foetal perfusion. Conclusions: Clinical complications known to be associated with excess umbilical cord length were analysed from the physics perspective, and formulae were established for use with real data derived from foetal Doppler scans and umbilical cord measurements.

In order to keep subscribers up‐to‐date with the latest developments in their field, John Wiley & Sons are providing a current awareness service in each issue of the journal. The bibliography contains newly published material in the field of prenatal diagnosis. Each bibliography is divided into 17 sections: 1 Books, Reviews & Symposia; 2 General Interest; 3 Normal Fetal Development; 4 Gametogenesis and Pre‐implantation Diagnosis; 5 First Trimester Diagnosis; 6 Second Trimester Diagnosis; 7 Fetal Diagnosis by Ultrasound and Other Imaging; 8 Maternal Screening; 9 Screening for Carriers of Genetic Abnormality; 10 Technological Developments; 11 Confined Placental Mosaicism and Uniparental Disomy; 12 Molecular Cytogenetics; 13 Fetal Cells in Maternal Circulation; 14 Fetal Therapy; 15 Psychosocial Aspects; 16 Epidemiology and Environmental Factors; 17 Developmental Pathology. Within each section, articles are listed in alphabetical order with respect to author. If, in the preceding period, no publications are located relevant to any one of these headings, that section will be omitted
