The umbilical cord is too short
Introduction
Introduction The length of the umbilical cord shorter than 30 cm is called the umbilical cord is too short. The umbilical cord is too long and too short to be congenital, not for some reason. For obvious reasons, it is congenital, which is caused by poor embryonic development. It may be caused by oral administration of some drugs during pregnancy, resulting in poor embryo development. Under normal circumstances, it does not matter, prenatal examinations can be done on time, generally in the 20th, 24th, 28th, 32nd, 36th, 37th, 38th, 39th, 40th week of pregnancy to do so several prenatal examinations. The umbilical cord is too short due to its own length, and the umbilical cord of normal length may be relatively short due to the high attachment position or the umbilical cord around the neck and around the body.

Diagnosis
Differential diagnosis
The average length of the umbilical cord is 50 cm, shorter than 30 cm is too short, and longer than 70 cm is too long. The umbilical cord is too short due to its own length, and the umbilical cord of normal length may be relatively short due to the high attachment position or the umbilical cord around the neck and around the body. The umbilical cord is too short, due to the decline of the fetus during childbirth, the umbilical cord is thinned and broken, and there is fetal intrauterine hypoxia, umbilical hernia, or the fetal decline is blocked, resulting in complications such as delayed labor, placental abruption, and uterus overturning. Endangering the life of the fetus; the umbilical cord is too long, which is the main factor of umbilical cord entanglement, knotting and prolapse. In these cases, the umbilical cord blood circulation can be blocked, resulting in fetal hypoxia or even death.
