Congenital heart defects (CHD) are very common in patients with trisomy 18 (T18) and trisomy 13 (T13). The surgical indication of CHD remains controversial since the natural history of these trisomies is documented to be poor. To investigate the outcome of CHD in patients with T18 and T13, we collected and evaluated clinical data from 134 patients with T18 and 27 patients with T13 through nationwide network of Japanese Society of Pediatric Cardiology and Cardiac Surgery. In patients with T18, 23 (17%) of 134 were alive at this survey. One hundred twenty-six (94%) of 134 patients had CHDs. The most common CHD was ventricular septal defect (VSD, 59%). Sixty-five (52%) of 126 patients with CHD developed pulmonary hypertension (PH). Thirty-two (25%) of 126 patients with CHD underwent cardiac surgery and 18 patients (56%) have survived beyond postoperative period. While palliative surgery was performed in most patients, six cases (19%) underwent intracardiac repair for VSD. Operated patients survived longer than those who did not have surgery (P < 0.01). In patients with T13, 5 (19%) of 27 patients were alive during study period. Twenty-three (85%) of 27 patients had CHD and 13 (57%) of 27 patients had PH. Atrial septal defect was the most common form of CHD (22%). Cardiac surgery was done in 6 (26%) of 23 patients. In this study, approximately a quarter of patients underwent surgery for CHD in both trisomies. Cardiac surgery may improve survival in selected patients with T18. 相似文献

Developmental data were abstracted from medical records on 50 trisomy 18 individuals ranging in age from 1 to 232 months and 12 trisomy 13 individuals ranging in age from 1 to 130 months. Data on the age when trisomy 18 and trisomy 13 children achieved developmental skills were collected from a larger group of 62 trisomy 18 individuals and 14 trisomy 13 individuals whose families filled out parent questionnaires. Developmental quotient (DQ), defined as developmental age divided by chronological age, averaged 0.18 for trisomy 18 and 0.25 for trisomy 13. There was a dramatic drop in DQ from infancy to later childhood. The highest DQs and the greatest variation in DQs were in the first 2–3 years of life. Developmental ages in 7 skill areas were significantly different, with daily living and receptive language having the highest values and motor and communication skills having the lowest. When chronological age was taken into account, there was no significant difference in DQs in the same 7 skill areas, although there was a trend that was similar to the pattern of differences with developmental age. Older children could use a walker, understand words and phrases, use a few words and/or signs, crawl, follow simple commands, recognize and interact with others, and play independently. Walking and some toileting skills were also reported for trisomy 13. Although individuals with trisomy 18 and trisomy 13 were clearly functioning in the severe to profound developmentally handicapped range, they did achieve some psychomotor maturation and always continued to learn. © 1994 Wiley-Liss, Inc. 相似文献

The natural history of trisomy 18 and trisomy 13 was investigated using data derived from parent questionaires and medical records from 98 families with an index case of trisomy 18 and 32 families with an index case of trisomy 13. Data are presented on pregnancy, delivery, survival, medical complications, immunizations, growth, cause of death, cytogenetics, and recurrence risk. Half of the trisomy 18 babies were delivered by C-section. Fetal distress was a factor in half, and the only reason in a third of C-section deliveries. One minute Apgar scores were significantly lower in C-section and breech deliveries. There were more small for gestational age babies than in the general population, but most of the low birth weight new borns were small for gestational age, unlike the general population. Survival in this group of children was better than in other studies due to ascertainment bias. There were more girls than boys at all ages for both conditions, and the sex ratio decreased with time. Growth curves for length, weight, head circumference, and weight vs height are provided. Long-term survival did not appear to be due to mosaicism. We found no adverse reactions attributable to immunizations. At age 1 year there was an average of approximately 2 operations per living child. We report the second case of successful major cardiac surgery in a trisomy 18 child. Almost 70% of deaths were attributed to cardiopulmonary arrest. The sibling recurrence risk for trisomy 18 or trisomy 13 was 0.55%. © 1994 Wiley-Liss, Inc. 相似文献

Cytogenetic analysis of amniotic fluid cells from a 31-week-old fetus suffering from polyhydramnios revealed that there were two cell lines, each with either trisomy 13 or trisomy 18. We studied the origin and mechanism of formation of this unique mixoploidy by tracing chromosomal heteromorphisms as genetic markers, and showed no discordance of parent-child transmission between the two cell lines in any of the heteromorphisms examined. The result indicated that the mixoploidy is not chimerism but mosaicism and that the mechanism of mosaic development is most likely due to two non-disjunctional events which had occurred independently at the two-cell stage of the zygote. A girl was born at the 38th gestational week and her clinical features were mainly those for trisomy 13. Chromosome analysis of the newborn confirmed +13/+18 mosaicism in fibroblasts from the skin and chorionic plate, while cord blood lymphocytes and chorionic villus cells showed only the +18 cell line. 相似文献

We report on an adult woman with profound mental retardation and multiple anomalies who consists of 3 cell lines: one with trisomy 18, one with trisomy 13, and a normal cell line. Her phenotype includes manifestations of both trisomy syndromes. The origin of these cell lines could have been a doubly aneuploid (48,XX+ 13, + 18) or singly aneuploid (47,XX + 18 or 47,XX, + 13) zygote with subsequent mitotic nondisjunctions, or a normal zygote with multiple mitotic nondisjunctions. There have been four previous reports of mosaicism involving both trisomy D and trisomy E; all died in the first six months of life. Two of these cases had a doubly aneuploid (48,XX, + D + E) cell line. Our patient illustrates the need for study of several tissues in patients with complex aneuploidy syndromes or atypical manifestations of a given syndrome (such as prolonged survival), as well as the need for caution in counseling families about prognosis for survival in autosomal trisomies which usually are lethal. 相似文献

Trisomy 13, trisomy 18, and triploidy belong to the chromosomal abnormalities which are compatible with life, but which are also associated with a high rate of spontaneous abortion, intrauterine death, and a short life span. This study was conducted to analyze natural outcome after prenatal diagnosis of these disorders. Between January 1, 1999 and December 31, 2009, we investigated all amniocenteses and chorionic villus biopsies carried out at our department. All cases with fetal diagnosis of triploidy, trisomy 13, and 18 were analyzed, with a focus on cases with natural outcome. Overall, 83 (78%) cases of pregnancy termination and 24 (22%) patients with natural outcome (NO) were identified. The NO group included 15 cases of trisomy 18, six cases of triploidy, and three cases of trisomy 13. No case of triploidy was born alive. The live birth rate was 13% for trisomy 18 and 33% for trisomy 13. The three live-born infants with trisomy 13 and 18 died early after a maximum of 87 hr postpartum. Our data are consistent with the literature concerning outcome of triploidy, with none or only a few live births. Analyzes of trisomy 13 and 18 indicate a very short postnatal life span. Different study designs and diverse treatment strategies greatly affect the fetal and neonatal outcome of fetuses with triploidy, trisomy 13, and 18. More studies analyzing natural outcome after prenatal diagnosis of these chromosomal abnormalities are needed. Non-termination of these pregnancies remains an option, and specialists advising parents need accurate data for counseling. 相似文献

We report the 6th case of double trisomy X and 18, ie, 48,XXX,+18. The infant lacked overlapping fingers, simian creases, and structural heart disease and is alive at 275 days. Two X chromosomes were late replicating. Anomalies of the hands and kidneys involved only the right side in the present case; review of the five previous cases of 48,XXX,+18 also showed that anomalies of kidneys, hands, and ears affected predominantly the right side in three patients. 相似文献
