Umbilical cord pathology Pathology accidental

Umbilical cord pathology
Pathology accidental
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 blood
Windings 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 Nodes
Nodes may be false or true cord, single or multiple.

 
c. umbilical cord prolapsing
Is this belt loops at the lower end of the uterus, together with the anchor.

 
d. thrombosis They 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 cord They are exceptionally rare contingencies that may arise in cases of short cord, subjected to traction during a twist or precipitate obstetric maneuvers.

 
f. cord torsion Normally, 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 stenosis In 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 edema It is a rarity, most commonly being associated with fetal edema.
