Pons Anteroposterior and Cerebellar Vermis Craniocaudal Diameters in Fetuses With Down Syndrome

Objectives To investigate the pons anteroposterior diameter (APD) and cerebellar vermis craniocaudal diameter (CCD) of fetuses with Down syndrome (DS). Methods This was a prospective observational study including 200 low-risk pregnancies and 18 pregnancies with fetuses who had DS. A midsagittal view was obtained to measure the pons APD and cerebellar vermis CCD. Gestational age-related 5th, mean, and 95th percentiles for the pons APD and cerebellar vermis CCD between 18 and 32 weeks' gestation were created from the low-risk population. Each measurement of a fetus with DS was plotted on growth charts, and those below the 5th percentile for gestational age were considered small. Results The pons APD and cerebellar vermis CCD measurements were below the 5th percentile for gestational age in 7 of the 18 (38.8%) fetuses with DS. Fetuses who had pons APDs below the 5th percentile for gestational age also had cerebellar vermis CCDs below the 5th percentile. Fetuses who had pons and cerebellar vermis measurements below the 5th percentile for gestational age on the initial examination continued to have small measurements during follow-up. Conclusions Fetal pons and cerebellar vermis abnormalities could be observed prenatally in fetuses with DS, which could help in the antenatal counseling and postnatal follow-up of such pregnancies

A case of parasitic myoma 4 years after laparoscopic myomectomy

We present a case of parasitic myoma complaining of abdominal pain, constipation, dyspareunia and dysmenorrhea 4 years after laparoscopic myomectomy. We performed laparoscopic myomectomy for multiple parasitic myomas. Three myomas were very firmly attached to bowel and mesentery. Parasitic myoma after laparoscopic surgery is very rare condition there are almost 35 cases in the literature. It is related with variable symptoms or can be asymptomatic. Laparoscopic surgeons should be aware of this situation, and further investigation should be made in case of suspicion. Surgery for parasitic myomas can be difficult in case of bowel and mesentery involvement and patient should be informed about the extensive surgery

Fetal left ventricular modified myocardial performance index and renal artery pulsatility index in pregnancies with isolated oligohydramnios before 37 weeks of gestation

Objective: The aim was to evaluate fetal left modified myocardial performance index (Mod-MPI) and renal artery Doppler parameters in fetuses with isolated oligohydramnios and a normal amount of amniotic fluid

Leriche's syndrome and twin pregnancy

Leriche's syndrome is characterized by chronic obstruction of the abdominal aorta and iliac arteries. A patient with Leriche's syndrome presented with twin pregnancy and severe preeclampsia at 32 weeks' gestation. Cesarean delivery was performed and the patient was admitted to the intensive care unit. Magnetic resonance angiography showed total occlusion of the distal abdominal aorta, common, and external iliac arteries. There were extensive collateral vessels between the lumbar arteries and iliolumbar arteries. The patient was discharged in an improved clinical condition. Leriche's syndrome and pregnancy demonstrating complete aortic, common, and external iliac artery occlusion is very rare in the literature. Despite complete occlusion, viability of the fetus can be achieved with collateral vessels

Complete Hydatidiform Mole and Co-Existing Live Fetus after Intracytoplasmic Sperm Injection: A Case Report and Literature Review

Introduction: Twin pregnancy with complete hydatidiform mole and co-existing fetus (CHMCF) is an uncommon obstetric entity and may occur after assisted reproductive technologies. These pregnancies are associated with severe complications for both mother and fetus and the management is challenging. Case Report: We report a twin pregnancy after intracytoplasmic sperm injection (ICSI) treatment with CHMCF which delivered at 26 gestation weeks due to severe preeclampsia. The 625g neonate survived without any complication. The woman had persistent trophoblastic disease with lung metastasis and was treated with single agent methotrexate. We also present a brief review of the literature about the outcomes of CHMCF after ICSI. Conclusion: CHMCF may occur after ICSI treatment. Pregnancies with CHMCF are associated with severe complications however under close follow-up successful outcomes could be achieved in such pregnancies

Are complicated monochorionic twins more susceptible to indomethacin-induced fetal ductal constriction? Two cases of laser surgery for Twin-Twin Transfusion syndrome

Indomethacin is a commonly used medication against preterm delivery. Several reports of fetal ductal constriction have been described after indomethacin use in the literature; however, there are no previously documented reports describing an association between Twin-Twin Transfusion syndrome and a constrictor effect of indomethacin on the ductus arteriosus. Two patients were referred to our department for Twin-Twin Transfusion syndrome and each underwent placental laser surgery. Constriction of the ductus arteriosus occurred as early as 20 and 24 weeks’ gestation following maternal use of indomethacin after laser surgery. Spontaneous amelioration was observed after discontinuation of the drug. The constrictor effect of indomethacin on the ductus arteriosus can be observed even after a single dose and as early as 20 weeks of gestation in complicated monochorionic twin pregnancies. We emphasize meticulous use of indomethacin in complicated monochorionic twin pregnancies because the constrictive effect seems to be independent of gestational age
