1/187. uterine artery embolization--a successful treatment to control bleeding cervical pregnancy with a simultaneous intrauterine gestation.A case of a woman suffering from a bleeding heterotopic cervical pregnancy is described. The concurrent cervical pregnancy and intrauterine gestation were diagnosed by ultrasound and bleeding was initially controlled with selective fluoroscopic uterine artery embolization. A selective fetal reduction was done with ultrasound-guided intracardiac potassium chloride. uterine artery embolization has been used successfully to control haemorrhage in cervical pregnancies when the main goal was to allow preservation of the uterus, thus maintaining potential fertility. This is the first report of arterial embolization used to control bleeding for maintaining a concurrent intrauterine heterotopic pregnancy in an in-vitro fertilization patient. Unfortunately, subsequent conservative measures led to undesired outcome. This procedure initially controlled the bleeding without disrupting the intrauterine fetal cardiac activity.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
2/187. Early prenatal diagnosis of cord entanglement in monoamniotic multiple pregnancies.OBJECTIVES: Cord entanglement is a severe complication in monoamniotic multiple pregnancies. Three cases were reviewed to determine how early ultrasound diagnosis might improve counselling and management. methods: In two monoamniotic twin and one dichorionic diamniotic triplet pregnancies, cord entanglement was detected between 10 and 18 gestational weeks by color Doppler and pulsed Doppler velocimetry. Pregnancies were followed up on a weekly basis with special observation of fetal behavior and use of color Doppler velocimetry. RESULTS: In Case 1, a monoamniotic twin pregnancy with cord entanglement close to the umbilical insertions was diagnosed at 10 weeks. Longitudinal follow-up showed intrauterine death of both twins at 15 weeks. In Case 2, entanglement of the umbilical cords of two monoamniotic triplets within a dichorionic diamniotic triplet pregnancy was diagnosed at 10 weeks. The pregnancy continued uneventfully until 35 weeks when cord entanglement was confirmed at cesarean section. All triplets have since developed normally. In Case 3, monoamniotic twins were diagnosed at 18 weeks. color Doppler detected side-by-side insertion of the umbilical cords and Doppler velocimetry suggested an entanglement at the chorionic plate. The pregnancy was complicated by polyhydramnios. cesarean section at 36 weeks confirmed cord entanglement at the chorionic plate. Postnatal computer angiography and morphological examination of the placenta showed the presence of superficial artery-to-artery and vein-to-vein anastomoses and of deep arteriovenous shunts. The development of the twins was uneventful. CONCLUSIONS: Diagnosis of cord entanglement is feasible early in gestation. Future protocols are proposed to document the gestational age at detection, the location, and the Doppler flow patterns and to facilitate the assessment of short- and long-term development.- - - - - - - - - - ranking = 223.66391882449keywords = umbilical, artery (Clic here for more details about this article) |
3/187. Lymphoproliferative disorder of fetal origin presenting as oligohydramnios.lymphoma involving the placenta or fetus remains a very rare event. All cases reported to date have shown the lymphoma cells to be of maternal origin in that the tumor cells have preferentially involved the intervillous spaces with sparing of the villi and fetal circulation. We report a novel case of a monoclonal primary placental Epstein-Barr virus (EBV)-associated B-cell lymphoma of fetal origin. The placenta of a 20-week stillborn fetus born to a 19-year-old gravida 1 para 0 woman, presenting with oligohydramnios, showed a large cell infiltrate confined within villi and sparing the intervillous spaces, indicative of preferential involvement of the fetal circulation. Necropsy did not show any other site of involvement by malignant lymphoma or other abnormalities. Immunophenotypic studies showed the tumor cells to be of B-cell phenotype with a relatively high proliferation rate. EBV EBER1 rna was identified in more than 95% of tumor cells, and polymerase chain reaction studies showed EBV EBNA1 strain type A and wildtype EBV LMP1. Analysis of the immunoglobulin heavy chain by polymerase chain reaction showed a monoclonal B-cell population. in situ hybridization studies using a commercially available probe directed at repeated sequences on the human y chromosome showed a single intense signal within trophoblastic epithelium and lymphoma cells, indicative of male origin. The mother remains in good health 11 months after delivery.- - - - - - - - - - ranking = 0.051222718224101keywords = single (Clic here for more details about this article) |

5/187. Pressure in the hydrocephalic fetal head during the first stage of labor.Intraamniotic pressure was studied in the 30th week of amenorrhea in relationship with fetal intracranial pressure with open-tip catheters. The fetus had a severe hydrocephalus (echoscopy 16 cm) due to a teratologic malformation of the cerebrum. Clinically nonoperative treatment was indicated. intracranial pressure (X) was invariably higher than intraamniotic pressure (Y) between contractions: Y = 2.04 0.54 X, and during contractions: Y = 5.30 0.55 X. There was no definite relationship between intrauterine and intracranial pressure, and the fetal tachogram. A definite relationship was established with the supine position of the patient and decelerations in the fetal tachogram. It is suggested that when fetal cardiac decelerations are seen during the first stage of labor it seems advisable to look for factors such as umbilical cord compression and decrease of materno-placental perfusion rather than fetal head compression.- - - - - - - - - - ranking = 74.443528497053keywords = umbilical (Clic here for more details about this article) |
6/187. Anomalous ependyma inducing split cord and meningomyelocele?The case is that of a female fetus of 17 to 18 weeks' gestation with major defects of the central nervous system: (1) The thoracic vertebrae demonstrated rachischisis, with segmental diplomyelia; the duplicated cords were dissimilar in size and lay side by side within a single meningeal sheath lacking a dividing septum or spur. Cranially to the divided cord lay an unsplit segment of "open cord" lacking the posterior elements and exposing the centrally placed ependyma of the central canal flanked by glial and epidermal lining, respectively; it could be regarded as an example of a meningomyelocele. (2) Heterotopic massed ependymal cells, some of which were actively proliferating, were associated with the choroid plexus in the brain. Minor anomalies included cerebellar heterotopia and the malpositioning of dorsal root ganglia outside the meningeal sheath. Because the ependyma is such a powerful inducer of the development of neighboring tissue, the findings could be united by a common pathogenic theme, viz problematic ependymal development and migration within both the brain and spinal cord. The causative agent responsible for these abnormalities remains unidentified, but the balance of evidence suggests that its effect was felt during the second week of postconceptual age.- - - - - - - - - - ranking = 0.051222718224101keywords = single (Clic here for more details about this article) |
7/187. Outcome of twin pregnancies in patients with haemoglobinopathies--case reports.pregnancy in patients with haemoglobinopathy is associated with increased risk of maternal and perinatal morbidities and mortalities. Multiple pregnancy is potentially more hazardous than singleton pregnancy. There is a dearth of information concerning multiple pregnancies in patients with haemoglobinopathy. Four of such patients seen in the obstetric service of the University College Hospital, Ibadan are presented here and discussed. Increased surveillance and elective caesarean delivery are suggested in the management of these patients.- - - - - - - - - - ranking = 0.051222718224101keywords = single (Clic here for more details about this article) |
8/187. hemangioma of the umbilical cord: stenotic change of the umbilical vessels.We report a rare case of an umbilical cord hemangioma diagnosed by ultrasound at 16 weeks of gestation. The umbilical cord consisted of a hemangioma nodule and pseudocysts near the placental insertion, a large gelatin-like swelling adjacent to the nodule on its fetal side, and a short normal part extending to the navel. At 17 weeks of gestation, this condition resulted in the intrauterine death of the fetus. Microscopically, there were communications between the capillary of the hemangioma and the umbilical vessels, verifying the origin of the tumor. Moreover, the umbilical vein and one of the arteries changed stenotically due to the intravascular proliferation of the hemangioma. These findings indicate the possibility of a pathological association between the umbilical cord hemangioma and fetal demise due to impaired umbilical circulation.- - - - - - - - - - ranking = 1042.2093989587keywords = umbilical (Clic here for more details about this article) |
9/187. Maternal and neonatal outcome in a monochorionic twin pregnancy complicated by single intrauterine demise.Single fetal death in monochorionic pregnancies is believed to be associated with increased risk of perinatal morbidity and mortality for the living twin and risk of coagulopathy affecting the mother. In this report we present a case of single intrauterine death in a monochorionic twin gestation diagnosed in the 28th week of pregnancy.- - - - - - - - - - ranking = 0.25611359112051keywords = single (Clic here for more details about this article) |
10/187. Congenital hyperthyroidism: autopsy report.We report the autopsy of a stillborn fetus with congenital hyperthyroidism born to a mother with untreated Graves' disease, whose cause of death was congestive heart failure. The major findings concerned the skull, thyroid, heart, and placenta. The cranial sutures were closed, with overlapping skull bones. The thyroid was increased in volume and had intense blood congestion. Histological examination showed hyperactive follicles. The heart was enlarged and softened, with dilated cavities and hemorrhagic suffusions in the epicardium. The placenta had infarctions that involved at least 20% of its surface, and the vessels of the umbilical cord were fully exposed due to a decrease in Wharton's jelly. hyperthyroidism was confirmed by the maternal clinical data, the fetal findings of exophthalmia, craniosynostosis, and goiter with signs of follicular hyperactivity. Craniosynostosis is caused by the anabolic action of thyroid hormones in bone formation during the initial stages of development. The delayed initiation of treatment in the present case contributed to the severity of fetal hyperthyroidism and consequent fetal death.- - - - - - - - - - ranking = 74.443528497053keywords = umbilical (Clic here for more details about this article) |
