Includes eventualitatiile that cause compression of the umbilical vessels and fetal distress in succession through a complex mechanism (hypoxia, hypovolemia, vagal reflex).
a. umbilical cord bloodWindings are single or multiple segments of the cord around the fetus (neck, trunk, limbs), most frequently around the neck. Coil around torso are called scarf or camisole.
b. umbilical NodesNodes may be false or true cord, single or multiple.
c. umbilical cord prolapsingIs this belt loops at the lower end of the uterus, together with the anchor.
d. thrombosisThey are favored by velamentous insertion of the cord inflammation or circular. Although a rare event, umbilical vessel thrombosis of acute fetal distress may lead to intrauterine death.
e. Leakage cordThey are exceptionally rare contingencies that may arise in cases of short cord, subjected to traction during a twist or precipitate obstetric maneuvers.
f. cord torsionNormally, fetal active movements cause the cord twist, which may occur at any point along the length of cord. Sometimes twisting is so important compromise fetal circulation 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 interesting twist, it is considered that it is practically impossible to determine which is the initial twisting or fetal death. Twisting the reality of existence, the strangulation cord, leading to intermittent occlusion of the vessels if the funicular, which can cause cerebral hypoperfusion and consecutive fetal hypoxia.
g. cord stenosisIn terms of etiologic correlates with torsion and is associated with severe focal deficiency of gelatine Wharton. The consequence is the high rate of stenosis mortinatalitatii cord.
h. cord edemaIt is a rarity, most commonly being associated with fetal edema.
