Cord torsion

Normally, fetal active movements cause the cord twist, which may occur at any pointalong the length of cord. Sometimes twisting is so important compromise fetalcirculation and cause fetal death.
 
Clinically, the torsion is discovered during the expulsion of dead fetuses in utero.
 
Since, by an unknown mechanism after exitusul fetus in utero can occur very interestingtwist, it is considered that it is practically impossible to determine which is the initialtwisting or fetal death.
 
Twisting the reality of existence, the strangulation cord, leading to intermittent occlusionof the vessels if the funicular, which can cause cerebral hypoperfusion and consecutivefetal hypoxia.
