Hyrtl's unastomosis is indicated by an arrow. The two umbilical arteries are joined by a single anastomotic branch just before the insertion into the placenta.

The Hyrtl anastomosis is a common connection between the umbilical arteries near the cord insertion in most human placentas. It was speculated that it equalizes the blood pressure between the territories supplied by the umbilical arteries.

Hyrtl fissure (also known as tympanomeningeal fissure) is a congenital infralabyrinthic fissure through the petrous temporal bone. It is a very rare cause of spontaneous CSF otorrhea and meningitis.

The Hyrtl anastomosis (Figs 1 and 2) is the only connection between the two umbilical arteries (1, 2).Its variable anatomy is incompletely known despite the assessment of umbilical artery blood flow velocity waveforms (FVWs) in its vicinity at the cord insertion. The presence of a communicating vessel, the Hyrtl anastomosis, between the umbilical arteries is well described in pathological studies. Using different injection techniques, it has been speculated that this vessel acts as a pressure-equalizing mechanism between the different lobes of the placenta.

A study in full term placentas from AGA infants with normal umbilical artery blood flow Acta Obstet Gynecol Scand . a communicating loop between the right and left hypoglossal nerves, lying between the geniohyoid and genioglossus muscles or in the substance of the geniohyoid; it is found in about 1 in 10 people.

A significant difference was observed between the normotensive and pregnancy-induced hypertension cases, whereas the transverse type of anastomosis was mostly observed in pregnancy-induced hypertension. Hyrtl Anastomosis.

Hyrtl's anastomosis, the only connection between the two umbilical arteries. A study in full term placentas from AGA infants with normal umbilical artery blood flow

linkem Nervus hypoglossus im Musculus genioglossus. In higher plants, anastomosis is the connecting of tubular structures—for example, veins in leaves and branchings of latex vessels. In fungi, anastomosis is the connecting or concresence of two mycelium hyphae with the establishing of intercommunication between them. Hyrtl's anastomosis is normally developed in placentas from small for gestational age infants.

It is a very rare cause of spontaneous CSF otorrhea and meningitis. 2021-03-07 · (2003) Ullberg et al. Acta Obstetricia et Gynecologica Scandinavica. Background. The aim of this study was to investigate the occurrence and appearance of the anastomosis between the two umbilical arteries in placentas from infants small for gestational age (SGA). In addition, the length of the anastomosis and its distance from the cord insertion was shorter in specimens from hypertensive compared to normotensive subjects. We conclude that pregnancy‐induced hypertension alters the anatomy of Hyrtl's anastomosis, and in some circumstances, the placenta.
