Introduction: true umbilical cord knots are rare and occur between 0.3-1.3% of all pregnancies. The fetal mortality rate before delivery ranges from 4 to 10 times higher than in pregnancies with normal umbilical cords.

Case presentation: case 1: 39-year-old patient G3 P (1 eut and 1 ces) A0, obese, gestational age of 39.3 weeks, who attends the Hospital with uterine contractions of 3/10 minutes, good intensity, high presentation, cephalic and fetal heart rate (fcf) of 164 / min, previous cesarean section 2 years ago, plus sign, with a patent cervix 1cm, thick and intact membranes. Case 2: patient admitted to the Hospital at 41 years of age, obese, with G5 P4 A0, gestational age of 40, 4 weeks, the last delivery occurred 6 years ago, has contractions 2/10 minutes and fcf of 160 / minutes, with late decelerations in the cardiotocographic recordings (CTG), dilation of 2 cm with intact membranes and a thick and stiff neck. BP: 140/80, in chronic hypertensive and treatment with methyldopa 250mg every 6hrs. Case 3: patient who was admitted with 39 years of age, 41 weeks of gestation, G6 P5 A0, obese, the last delivery was performed with the application of forceps with low apgar, 3 years ago, has been treated with methyldopa 500mg every 8 hours for be a chronic hypertensive; she was admitted with a blood pressure of 120/80, she complains of pain in the lower abdomen.

Discussion: among the risk factors raised in the appearance of true umbilical cord knots, it was found: chronic arterial hypertension in the three patients, two multiparous, three with age equal to or greater than 39 years and all with cords greater than 60 cm. The normal length of the cord is (30 cms to 60 cms). It is posed as a risk of developing knots in the cord, with cords greater than.
