Hyrtl anastomosis

Arts, 1961 ( 16 ), investigated 65 placentas. Besides one case with single umbilical artery none lacked an anastomosis, but the types were similar. 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.

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.

Conclusions. By using angiography we were able to demonstrate the variable anatomy of the anastomosis of Hyrtl. The variability in the anatomic structure of Hyrtl's anastomosis is large, but studies on possible physiological correlates between structural variations and function are notably lacking .Because of the apparent importance of the anastomosis in distributing flow between the umbilical arteries and in the placenta, we investigated potential hypertension related anatomical changes.

In earlier investigations of Hyrtl’s anastomosis the placentas have often been unspecified, usually mentioned as ‘normal’ placentas (5, 15).

In earlier investigations of Hyrtl’s anastomosis the placentas have often been unspecified, usually mentioned as ‘normal’ placentas (5, 15). Most former studies have used injection corrosion technique in which the arteries of the placenta were rinsed from blood with tap water or saline solution and filled with, for example, celluloid solution.

The effect of this anastomosis is to equalize pressure between the placental lobes. The hyrtl anastomosis permits perfusion of the entire placenta even if one of the umbilical arteries is Hyrtl reported only a single anastomosis (Hyrtl, 1870).
