In HELLP syndrome patients it is very important to closely follow maternal vital signs and fluid intake and output, and to perform fetal status assessment tests. Of the biophysical parameters, Doppler flow measurement is an especially helpful predictor of poor perinatal outcome in growth retarded fetuses in HELLP patients. Patients with very low platelets have a significantly higher risk of intrauterine growth retarded fetuses.
A massive cervicothoracal lymphangioma was diagnosed in a fetus at 25 weeks of gestation. On ultrasound study, the mass showed septated, cystic components and extended from the right submandibular region to the right anterolateral thoracic wall including the right axilla and right scapula. Close sonographic follow-up revealed an increase in the size of the lymphangioma without fetal hydrops. An interdisciplinary approach including a pediatric surgeon, neonatologist, perinatologist and anesthesiologist was chosen. Elective cesarean section under general anesthesia was planned at 37 + 0 weeks of gestation. Surgical correction of the lymphangioma was successfully performed on the 4th day of life. Possible differential diagnoses and the obstetrical management are presented.
The objective of this study is to analyze the prenatal management and prognostic factors of hygroma colli cysticum by using cytogenetic tests and sonographic morphological features. All cases with hygroma colli cysticum diagnosed and managed at our Prenatal Diagnostics Unit between January 96 and September 2000 were analyzed. Sonographic morphological features were divided in two groups; nonseptated (n = 18) and septated (n = 12) hygroma colli cysticum lesions were compared with fetal karyotype results and pregnancy outcome data. Statistical analysis was performed by Chi-square test and statistical significance was defined as p <0.05. In 5 years, 30 cases with hygroma colli cysticum were identified. Cytogenetic results were obtained from 23 (76.7%) cases (four chorionic villus sampling and 19 amniocentesis). Chromosomal abnormalities were present in 13 cases (56.5%). The most common chromosomal abnormality was Turner Syndrome (four cases, 17.4%) and Trisomy 18 (four cases, 17.4%). Pregnancy outcome data were available for 29 patients. Those fetuses with septated hygroma colli cysticum tended to have a worse fetal outcome, without statistical significance (p >0.05), compared with the nonseptated hygroma colli cysticum cases (75 vs. 61.1%, respectively). Fetal hygroma colli cysticum, either septated or not, carries high risks of aneuploidies and adverse fetal outcome. Recommended management includes karyotyping and if parents decide to continue the pregnancy ultrasound scan at 20 to 22 weeks' gestation is necessary, for excluding associated anomalies. At birth, if the cystic hygroma persists, it should be noted that a respiratory difficulty can happen and a pediatrician should standby as a precaution.
We report the course and outcome of a pregnancy involving a giant fetal neck teratoma which was diagnosed at 23 weeks of gestation. Sonographic surveillance of the fetal neck revealed continuing growth of the tumor with development of polyhydramnios. Three-dimensional ultrasound provided additional detailed information on the external extent of the lesion. Color Doppler ultrasound showed intense arterial and venous flow with low resistance indices. Cesarean section under general anesthesia was planned in close cooperation with the neonatologist, pediatric surgeon and anesthesiologist because the size of the neck mass precluded vaginal delivery. Cesarean section was performed at 34 weeks of gestation following preterm rupture of the membranes. Orotracheal intubation was not successful because of compression of the airway and a tracheostomy could not be performed because of the risk of severe fetal hemorrhage from the tumor. The neonate died from respiratory insufficiency 66 min after birth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
