Objective To evaluate the clinical significance and prognosis of tetus with lateral ventriculomegaly.Methods We retrospectively analyzed 92 singleton pregnant women who were antenatally diagnosed with fetal ventriculomegaly by ultrasound in genetic conselling clinics,Department of Gynaecology and Obstetrics,Nanfang Hospital,Southern Medical University between August 2007 and August 2010.All participants were divided into three groups according to the width of the lateral ventricles:group A (10.0-12.0 mm,n＝50),group B (12.1-14.9 mm,n=38) and severe ventriculomegaly group (≥15.0 mm,n=4).All fetuses were followed up.Chi-square test(or Fisher's exact test),Bonfferoni method,Mann Whitney or Kruskal-Wallis test were used for statistics.Results In group A,B and severe ventriculomegaly group,18％ (9/50),65.8％(25/38)and 3/4 of fetuses were complicated with structural malformation,respectively (x2 =22.934,P =0.000),and statistical significance were found only between group A and B (x2 =20.798,P=0.000).The incidences of fetal chromosomal aberration were 4.0％ (2/50),7.9％ (3/38)and 0/4 in the three groups,respectively (x2＝0.878,P ＝ 0.645).Eventually,all four cases with severe cerebral ventriculomegaly were terminated.Among cases of mild ventriculomegaly,63 women continued the pregnancy (48 in group A and 15 in group B).The intrauterine improvement of group B was poorerthan that of group A (Z=-3.317,P =0.001).Respectively,three,ten and two cases of ventriculomegaly deteriorated,stabilized and regressed in group B,and the corresponding figures were 3,15 and 30 in group A.In group A,the prognosis of fetus with non-isolated ventriculomegaly was poorer than that of fetus with isolated ventriculomegaly (Z=-2.631,P=0.009).For neonates 14 days after birth (n=62),the rates of normal neonatal behavioral neurological assessment (NBNA) scoring were respectively 93.8％ (45/48) and 71.4％ (10/14) for groups A and B with statistical difference (Fisher's exact test,P =0.040).Bayley scales of infant development (BSID) used to evaluate infants at 12-month-old revealed that the psychomotor developmental index (PDI) between group A and group B had statistical difference (8,26 and 1 case of good,moderate and poor development in group A; one,seven and three cases in group B; Z=-2.203,P=0.043).However,the mental developmental index (MDI) between group A and B had no statistical difference.Twenty babies among the survived ones received magnetic resonance imaging (MRI) examination.The results showed that lateral ventricle width regressed in nine babies (45.0％) and progressed in one baby (5.0％).Ten cases (50.0％) did not change.The change of ventriculomegaly after birth was related to BSID evaluation.Better prognosis of fetuses were found in those with regressed ventriculomegaly (P=0.033).Conclusions Fetuses with mild ventriculomegaly (10.0 12.0 mm) have a favorable outcome.Further investigations,such as fetal development,chromosomal examination,intrauterine infection screening and MRI if necessary,are suggested for fetus with ventriculomegaly.Moreover,intensive intrauterine and postnatal follow-up is recommended.

OBJECTIVETo investigate the implications of a prenatal diagnosis of single umbilical artery (SUA) for chromosomal abnormalities and neonatal outcomes.

METHODSFrom January, 2008 to June, 2012, color Doppler ultrasound identified 44 fetuses with SUA. Prenatal diagnoses with amniocentesis or umbilical blood sampling were subsequently ordered for routine chromosome karyotyping and the newborns were followed up for assessing the neonatal outcomes.

RESULTSOf all the 44 fetuses, 24 had uncomplicated SUA, and 20 had other concurrent abnormalities (including 8 with abnormal ultrasound soft indexes and 12 with chromosomal abnormalities). The two groups of fetuses showed significant differences in gestational weeks at delivery and incidence of chromosomal abnormalities but not in neonatal weight, placenta weight or APGAR score.

CONCLUSIONSFetuses with a prenatal diagnosis of SUA and other development abnormities need to undergo prenatal chromosomal examination. For fetuses with uncomplicated SUA, careful ultrasound examination is necessary to avoid missed diagnosis of potential congenital abnormalities.

Objective To evaluate the clinical outcome of fetus diagnosed as mild and moderate isolated ventriculomegaly(IVM)and its correlation with imaging follow-up. Methods Totally,161 cases of single pregnancy whose fetus was diagnosed as mild or moderate IVM by ultrasound were administrated. Data of prenatal ultrasound examination, pregnancy outcomes, and the postnatal MRI results were collected. New borns' growth and development, language expression, movement coordination, auditory and visual function were followed up to evaluate the neurodevelopment. Results (1)Before birth:80.1%(129/161) of IVM disappeared before the delivery, 16.1%(26/161)remained stable, and 3.7%(6/161)continued to deteriorate.(2)Postnatal MRI: 8 cases(9.6%, 8/83)were diagnosed IVM, of which 3 cases were found additional abnormalities(1 case was the corpus callosum dysplasia and 2 cases were leukodystrophy). The additional abnormal detection rate was 3/8.(3)Postnatal assessments: There were 7 cases(8.9%, 7/79) neunatal behavioral neurological assessment (NBNA), 6 cases (7.6%, 6/79) Bayley scales of infant development (BSID)-psychomotor developmental index(PDI) and 3 cases (3.8%, 3/79) BSID-mental development index(MDI) whose scores were low. There was no significant difference of the NBNA and BSID scores between mild and moderate IVM (NBNA: x2=2.042,P=0.210; BSID-PDI: x2=-1.359,P=0.174; BSID-MDI: x2=-1.205,P=0.228). Follow-up of 9 cases(11.4%, 9/79)with low BSID score, 6 of them were found to be stable in the medial ventricle of the uterus, and the size of the lateral ventricle was normal after birth by ultrasound and MRI. Conclusions The majority of IVM fetuses have good prognosis, but there is also a risk of neurodevelopmental dysplasia. The postnatal follow-up should be paid attention to, and MRI should be performed as the postnatal imaging evaluation.

Objective To analysis the common abnormalities in fetus with ventriculomegaly and clinical significance. Methods Collected from March 2010 to December 2016,298 cases of pregnant women whose fetus with ventriculomegaly and accepted the prenatal diagnosis of pregnancy,including 109 cases of isolated cerebral ventriculomegaly(IVM),and 189 cases of non-isolated cerebral ventriculomegaly(NIVM).They were divided into mild groups(10.0-11.9 mm),moderate group(12.0-14.9 mm)and severe group(≥15.0 mm)according to the width of the lateral ventricle. Results(1)The most common abnormality of the NIVM were neurodevelopmental system(37.30%,94/252);The second was ultrasonic soft index(27.78%,70/252).(2)The most frequent combi-nation in mild group was ultrasonographic soft mark anomalies(44.76%,47/105),followed by other ultrasonic indi-cators(18.10%,19/105).The abnormal incidence of central nervous system was higher in middle group(45.16%, 42/93),followed by ultrasonic soft index abnormality(21.51%,20/93).The abnormality of the central nervous sys-tem was 62.96%(34/54)in severe group,followed by an abnormal(14.81%,8/54).(3)There was a difference in the nervous system and the ultrasonic-soft indicator between the non-isolated lateral ventricle dilation with different lateral ventricle widths(P<0.001).There was no difference in cardiovascular abnormalities. Conclusion Prena-tal ultrasound revealed that fetus with cerebral ventriculomegaly should carefully examine whether other abnormali-ties existed to determine the prognosis of the fetus and whether intervention should be taken.There was a difference between the different types of lateral ventricle and the prognosis.

Objective To investigate pregnancy outcomes and neurodevelopment in fetuses with ventriculomegaly. Methods This was a cohort study of 173 gravidas with singleton pregnancy who were diagnosed with fetal ventriculomegaly by ultrasound in Prenatal Diagnostic Center of Nanfang Hospital Affiliated to Southern Medical University from March 2010 to July 2016. Thirty normal gravidas who received antenatal care in the same hospital and at the same period were selected as control. Clinical data were collected. Gravidas who had chosen to continue their pregnancy were followed up to monitor the variations of fetal ventricular. Fetal mild and moderate ventriculomegaly were respectively defined as a ventricular atrial width of 10-12 mm and >12 mm but <15 mm. Isolated ventriculomegaly (IVM) indicated those without any other ultrasound abnormalities, otherwise the case would be defined as non-isolated ventriculomegaly (NIVM). Among the 173 gravidas, 54 cases were mild IVM, 53 mild NIVM, 26 moderate IVM and 40 moderate NIVM. Fetuses with chromosome abnormalities were excluded from the study. Neonatal behavioral neurological assessment (NBNA) was used to analyze the neonatal neurodevelopment at the age of 7 days, and Bayley scales of infant development was used to evaluate the development of nervous system at the age of 6 months through analyzing their mental development index (MDI) and psychomotor development index (PDI). Statistical methods included t test, χ2 test (or Fisher's exact test), nonparametric test, Mann-Whitney test and multiple Kruskal-Wallis H test. Results (1) Among the 107 fetuses with mild ventriculomegaly, 72.9％ (78), 23.4％ (25) and 3.7％ (4) of them regressed, stabilized and progressed,respectively; however, among the 66 moderate cases, the figures were 45.4％ (30), 37.9％ (25) and 16.7％ (11) respectively (χ2=15.769, P<0.001). For those in the IVM and NIVM subgroups within the moderate ventriculomegaly group, significant difference was shown [17(65.4％), 8(30.8％) and 1(3.8％) vs 13(32.5％), 17(42.5％) and 10(25.0％), χ2=8.552, P=0.014], but not within the mild groups (χ2=2.412, P=0.299). (2) There were 164 gravidas who continued their pregnancy and delivered. Significant differences in NBNA score were observed between the ventriculomegaly group and the control (37.70±1.80 vs 38.53±1.38, t= - 2.424, P<0.05). Numbers of neonates with NBNA score < 36 and ≥ 36 points were 5(4.7％) and 101(95.3％) in the mild group, and 8(13.8％) and 50(86.2％) in the moderate group (χ2=4.231, P=0.004). There was significant difference in NBNA score between the IVM and NIVM subgroup within neither mild nor moderate group (χ2 were 0.210 and 0.201, P were 1.000 and 0.720). (3) Totally, 137 cases completed the assessment of nervous system development at the age of 6 months. There was significant difference in PDI score between the ventriculomegaly group and the control (90.50±10.85 vs 95.80±9.65, t= - 2.471, P=0.014), but not in MDI score (95.42+11.20 vs 99.50+12.00, t= - 1.786, P=0.076). (4) The comparison of the proportion of excellent, average and poor PDI scores: Significant differences were found between the IVM and NIVM subgroup within the moderate ventriculamegaly group and in the different intrauterine outcome groups [IVM vs NIVM groups: 3(15.0％), 16(80.0％) and 1(5.0％) vs 1(3.1％), 24(75.0％) and 7(21.9％),Z= - 2.097, P=0.036;intrauterine regression, stable and progress group: 9(10.6％), 75(88.2％) and 1(1.2％);3(6.5％), 37(80.4％) and 6(13.1％) vs 0, 2(2/6) and 4(4/6), χ2=19.808, P<0.001], but not between the mild and moderate vetriculamegaly group, or between the subgroups within the mild ones (Z were - 1.869 and - 1.946, P were 0.062 and 0.052). (5) The comparison of the proportion of excellent, average and poor scores of MDI: Significant difference was only found among the different intrauterine outcome groups[13(15.3％), 71(83.5％), 1(1.2％); 2(4.4％), 41(89.1％), 3(6.5％) vs 0, 5(5/6), 1(1/6); χ2=7.980, P=0.018], but not in any other comparisons (all P>0.05). Conclusions Prognosis of fetal ventriculomegaly is affected by co-existed abnormalities and intrauterine progression. Fetus with mild ventriculomegaly can also have risk of abnormal neural development, suggesting that we should pay much attention to such cases and a regular follow-up is required.

Objective To investigate the risk assessment ,prevention and management for perioperative stroke in elderly patients with hip fractures. Methods A total of 179 patients aged 65 years and older were admitted to our department due to hip fracture. In managements of perioperative stroke ,the preoperative risk assessment and the management of stroke ,identifying the risk population for stroke prevention ,controlling risk factors of the preoperative stroke ,intraoperative monitoring , postoperative treatment ,etc.were studied retrospectively.The incidence of perioperative stroke was recorded and analyzed. Results Of 179 patients with hip fracture ,overviews of diagnosis and treatment were as follows.Twenty-four (24/179 ,13.41% ) cases did not receive operative treatments.Head and neck CT angiography(CTA)-showed severe stenosis or occlusion of intracranial artery and internal carotid artery were in 9(5.03% ,9/179)patients ,of whom the 5(2.79% ,5/179) cases underwent cerebrovascular digital subtraction angiography (DSA ) ,balloon dilation and stent implantation ,then received the operation for hip fracture 10 days later ,finally were discharged uneventfully.1 (0.56% ,1/179 ) patient underwent orthopaedic surgery due to the results of DSA showing no indication of interventional therapy ,and was discharged unevenfully.3 (1.68% ,3/179 ) patients refused to receive the further DSA examination or interventional therapy ,strongly demanded for orthopaedic surgery and would take the surgical risk ,and were discharged uneventfully.2(1.12% , 2/179)patients were found to have cerebral aneurysm diagnosed by CTA and DSA ,and underwent surgery for hipfracture without special treatment.2(1.12% ,2/179)patients were diagnosed as new occurrence of cerebral infarction before the operation ,and received head and carotid stenting at the department of cerebrovascular surgery ,followed by combined antithrombotic therapy of aspirin , clopidogrel and low molecular weight heparin for 4 weeks ,then underwent orthopaedic surgery for hip fracture.2 (1.12% ,2/179 ) patients were diagnosed as new cerebral infarction after orthopaedic surgery ,then were transferred to the department of neurology for treatment. Conclusions The thorough preoperative risk assessment and management of stroke ,reasonable perioperative antiplatelet and anticoagulation therapy ,intense intraoperative monitoring and active postoperative complications management make it possible for high-risk and new ischemic stroke patients with hip fractures to receive early orthopaedic treatment.
