Umbilical cord knots.

BACKGROUND: Umbilical cord knots may represent a hazard to the fetus, particularly as regards intrauterine death and fetal distress or asphyxia in labor. The object of this study was to analyze the impact of associated umbilical cord encirclements and cord length on fetal outcome and fetal weight deviation. METHODS: Among 22,012 births occurring in Akershus Central Hospital, there were 216 instances of umbilical cord knots. Fetal outcome, fetal weight deviation, associated umbilical cord encirclements and cord length were assessed. RESULTS: Neonates with a knotted cord are more often large-for-gestational age compared to other babies, and have longer umbilical cords. There is a 10 times higher chance of intrauterine fetal death with a knotted cord, but if this does not occur then there is no increased risk of obstetrical intervention and Apgar scores are the same as in other babies and other fetuses. CONCLUSION: There is an association between umbilical cord knots and umbilical cord encirclements. Knotting of the cord is not by itself lethal. Pregnancies with knotted cords have characteristics different from those with ordinary umbilical cord encirclements.

Umbilical cord encirclements and Apgar scores.

OBJECTIVE: To establish the relative influence of umbilical cord encirclements versus fetal growth restriction in determining fetal outcome. METHODS: Twelve thousand and thirty-nine singleton births were studied. The number of cord encirclements were noted. Fetal growth restriction was measured as standard deviations from gestational weight. Fetal outcome was determined by using Apgar scores after 5 minutes. RESULTS: For growth restricted babies, Apgar 5 was not affected by the presence of encirclements when corrected for the level of FGR. Only for infants larger-for-date did the encirclements affect their Apgar score. CONCLUSION: The poorer outcome for babies with cord encirclements and fetal growth restriction is due to the accompanying level of growth restriction.

Umbilical cord encirclements and fetal growth restriction.

OBJECTIVE: To establish whether the presence of umbilical cord encirclements around the fetal body influence fetal growth. METHODS: The encirclements, cord length, gestational age, and fetal weight at birth were recorded for 11,201 births occurring at our hospital during 1991-1994. RESULTS: The presence of umbilical cord encirclements is associated with fetal growth restriction (FGR), the severity of the restriction being positively related to the number of encirclements. Umbilical cord encirclements are also associated with a relative lengthening of the umbilical cord. Because there is a positive correlation between cord length and fetal weight, this association tends to offset the effects of the encirclements, giving the newborns a more normal birth weight than they would have had otherwise. The net result, however, is negative. CONCLUSION: Umbilical cord encirclements are associated with FGR.

Evaluation of endometrial thickness measured by endovaginal ultrasound in women with postmenopausal bleeding.

Endovaginal ultrasound scanning was used preoperatively in 100 women with postmenopausal vaginal bleeding referred for dilatation and curettage. The ultrasonographic appearance of the endometrium was related to the histologic diagnosis. Endometrial malignancy was found in 15 patients, in 2/45 (4.4%) of women aged less than 60 years and in 13/55 (23.6%) of women aged 60 years or more. Out of 54 patients with an endometrial thickness of less than 5 mm as measured by ultrasound, 3 had an endometrial malignancy, and 12 of 45 with an endometrial thickness of 5 mm or more, had an endometrial malignancy. The sensitivity of ultrasound to detect malignancy was 80%, the specificity was 60%, the positive and negative predictive values were 26% and 94.4%. The sensitivity and the negative predictive value was not high enough to replace histologic examination of the endometrium.

Fertility outcome after treatment of tubal pregnancy by laparoscopic laser surgery.

In 150 women with tubal pregnancy consecutively treated over a two year period by laparoscopic techniques, 74 were treated conservatively by linear salpingotomy with carbon dioxide laser laparoscopy and 76 cases non-conservatively through the laparoscope by salpingectomy. Between 15 and 37 months later all patients were contacted by means of questionnaires to evaluate subsequent fertility outcome. Sixty-six percent (38/58) of those women who desired pregnancy after conservative laparoscopic treatment achieved an intrauterine pregnancy. The corresponding rate for women who desired pregnancy after salpingectomy was 45% (18/40). The recurrent ectopic pregnancy rates in the two groups were 7% (4/58) and 10% (4/40), respectively. This study confirms that tubal pregnancy can be appropriately managed by laparoscopic laser surgery with the advantages of minimal invasive techniques.

Treatment of tubal pregnancy by laparoscopic laser surgery.

We present 150 consecutive cases of tubal pregnancy treated by laparoscopic techniques. A three-puncture technique was used. 74 cases were treated conservatively by linear salpingotomy with carbon dioxide laser laparoscopy and 76 cases were treated nonconservatively through the laparoscope by salpingectomy or tubal resection. Contra-indications to laparoscopic surgery were haemodynamically unstable patient and interstitial pregnancy. Seventy-five per cent of all tubal pregnancies were treated by laparoscopy in the period studied. No complications were encountered during the laparoscopic operations. Two patients needed a second laparoscopy, while 2 others underwent a subsequent laparotomy. This study has shown that tubal ectopic pregnancies can in most cases be effectively managed by laparoscopic techniques.

[An epidemic of ectopic pregnancies in Ostre Akershus. Looking for possible causes].

During the period 1969 to 1985, 640 women with a confirmed diagnosis of ectopic pregnancy were admitted to Sentralsykehuset i Akershus. The case histories were reviewed for possible predisposing factors. From 1969 to 1985 the frequency of ectopic pregnancy increased threefold in relation to the number of conceptions in the same region. Until 1978 the major part of this increase was observed among women with IUCD in situ. Women who had previously undergone surgery on the uterine tubes accounted for the greater part of the increase in extrauterine pregnancies after 1976. A large year-to-year variation was found among women with neither of the above predisposing factors. However, a rising frequency of ectopic pregnancies was also observed in this group. It appears that the risk of ectopic pregnancy is greater among women using IUCD than among women using other methods of contraception.

Short umbilical cord as a cause of fetal distress.

The purpose of this study was to examine if a short umbilical cord might give rise to fetal distress of such a severity that would necessitate operative delivery. Review of the literature gave little clarification. Out of a database consisting of 7212 births, 5885 were included in the study according to pre-set criteria. The incidence of operative delivery was then compared with cord length. A significantly higher incidence of forceps deliveries and vacuum extractions was found when cord length was less than 40 cm. The incidence of cesarean section was also higher for the shorter cords. There was no increased need for neonatal resuscitation for the babies with the shortest cords.

Uterine size, parity and umbilical cord length.

It seems to be a widely held notion that the uterine cavity is larger during a woman's later pregnancies than during her first pregnancy. The direct evidence for this is, however, scarce. The umbilical cord length at term is one measure of the fetal intrauterine mobility, and therefore indirectly of the space in which the fetus moves. If the uterine cavity is larger during later pregnancies, the cord length of the babies in these pregnancies should be longer. We have compared the cord lengths of 1839 babies, divided into three groups: babies born of primiparous, secundiparous and tertiparous women. The difference in mean cord length is statistically significant between the first and the third group. This supports the theory of a larger intra-uterine space in later pregnancies. We also examined 159 mothers, measuring the umbilical cord length of their first and second babies. A significant positive correlation was found, in that the first baby tended to have the shorter cord. A control group with matching, but unrelated babies showed no such correlation. The results seem to us to support the stated theory further.
