Discussion & Conclusion

We revised 493 cases of mortality II perinatal in a General hospital.

The rate of II perinatal mortality in our hospital is 18.0 it is high and although the hospital has appropriate technological advances the mortality II perinatal continues being a serious problem of health.

We studied r correlation between amenorrhoea and birthweight by eight years. The r coefficient of 0.79 is strong, positive and it indicate us a narrow relationship between these two variables; In the graph the lineal regression is strong and positive; the behavior of the r correlation remains very similar to the cases of alive patients. We Showed the attention that in patients with congenital anomalies the weight is low, means + - .

We didn't find clinical difference neither statisticses between the fetal deaths and neonatal deaths of the studied cases. The postpartum lenght of stay varied in the stillbirths it was 0 days and they in the neonatal deaths were 4.5 days.

The 6 groups of more frequent illnesses corresponded to the IRDS, congenital anomalies, prematurez, pathology of cordon and placenta, infections and birth trauma.Figure No 3, figure 4, figuere 5, figure 6

The prospective risk of stillbirth was elevated in certain ethnic groups and increased significantly with advanced maternal age, multiple gestation, and lack of prenatal care.

It associated with preterm birth had more reproductive history variables (maternal age, parity, marital status, prior spontaneous abortion, prior induced abortion, prior stillbirth or neonatal death, sex of infant.

The relative importance of these umbilical complications is pointed out and discussed in regard to clinical and pathological factors.

Umbilical cord stricture is an uncommon but distinctive condition associated with intrauterine fetal death.

Morphologically, most infants are macerated and an extremely narrow segment of umbilical cord is usually seen at the fetal end and rarely at the placental end or in multiple sites along the cord. The findings of this study support the view that the condition can cause fetal death and alerts both pathologists and clinicians to the important features identifying this cause of perinatal wastage.

The pathologic examination showed umbilical cord torsion and an organized thrombus at the site of the torsion. Perinatal histopathologic examination is important in diagnosis.


We reported 493 cases of II perinatal mortality. Our r correlation were 0.79 it is strong and positive and it is similar at live newborn.
