“…Based on the fetopathological studies of all twin fetuses in his practice, Livingston and Poland [20] reported some kind of malformation in 21%, which is slightly higher than the figures for twin and triple miscarriages in our sample at 14 and 16%, respectively. According to the results by Arteaga et al [1] , in the case of multiple pregnancies the incidence of congenital malformation was around 25-30% higher than in singleton pregnancies.…”

Objective: We aimed to analyze, based upon autopsy, the main characteristics of miscarriages in the second trimester. Methods: We have processed the results of fetopathological investigations of 544 aborted fetuses resulting from 486 second-trimester miscarriages. Results: Malformation could be identified in 13.05% of all cases. In almost one third of the patients there was a positive history. In the cases having a malformation, expressed dominance of male fetuses could be observed. Among the fetopathologically identified malformations, 49 were isolated. The most common was the single umbilical artery (22.4%). In 1.3% of the cases a chromosome aberration was verified. Conclusion: Miscarriage in pregnancies complicated by a malformation occurs approximately 3 weeks earlier than in cases without a confirmed malformation. There is practically no difference between affected and unaffected miscarriages as far as the cumulative ratio of positive history is concerned. A single umbilical artery alone predisposes to miscarriage, while in association with other malformations it may result from chromosome aberration.

“…The following mechanisms are implicated as possible causes of this anomaly: (1) early amnion rupture before obliteration of the extraembryonic coelom [3]; (2) abnormal splitting of the embryo at 4 gestational weeks [3]; (3) disturbance of the blood flow due to vascular rupture, as described in cocaine users [4][5][6] and (4) a special situation in monozygotic twins [7][8][9][10][11].…”

We report on a case of embryonic anomaly detected at 9 + 5 gestational weeks. The lower part of the embryo was located in the coelomic cavity. Lower extremities could not be depicted. The abdominal wall showed the appearance of omphalocoele. After termination of pregnancy at 10 weeks, autopsy confirmed the anomaly of the lower embryonic parts consistent with the diagnosis of body stalk anomaly. To our knowledge, this is the first observation of this condition before 10 gestational weeks.

“…Several investigators have studied the frequency of twinning among spontaneously aborted gestational material; their results range from 0.3% to 20% [3,12,23]. One recent study found 53 twin pairs among 1,939 spontaneous abortions, for a frequency of 2.7% [23].…”

In general, it has not been recognized that many twin or multiple gestations are lost in utero early in pregnancy. Until the advent of ultrasound, the ability to document early human fetal loss in multiple gestation was difficult. However, recent reports of serial ultrasound examinations of pregnant women have documented the "disappearance" of at least one of two gestational rings. Furthermore, the number of twins observed at delivery was significantly less than the number of twin conceptions originally identified by ultrasound during the first trimester. These observations led to the concept of the "vanishing twin" [8,10,13,15,17,20,22,35,41].In order to obtain reference and personal data on this subject, we reviewed the literature and corresponded with members of the International Society for Twin Studies and obstetricians affiliated with Northwestern University Medical School, Chicago, Illinois. The nine studies that have documented this phenomenon cite "disappearance" rates ranging from 0% to 78%, depending on patient population and timing of ultrasonography [8,10,13,15,17,20,22,35,41]. Several explanations are offered: physiological mechanisms of "disappearance" (resorption or formation of a blighted ovum or fetus papyraceus), artifactual error, incomplete scanning technique, and poor quality ultrasound equipment. The only complication thus far associated with "disappearance" of a fetus is slight vaginal bleeding.
