Objective To detect the normal values of the fetal coronary sinus(CS) in length(L) .diameter (D) and diameter-to-length ratio(D/L) using fetal echocardiography and assess the clinical significance of dilated CS. Methods Fetal echocardiography were performed in 218 normal fetuses from the 20th to the 40th week of gestation. The L,D and D/L of CS were measured and the standard values of the normal fetal CS were established. A second group of 8 fetuses with dilated CS were assessed compared to the values of normal fetuses. Results The L and D of normal fetal CS correlated well with the gestational weeks (Linear regression equation is L= - 0. 94 + 0. 4 weeks, r = 0. 661, P<0. 0001 ;D= - 0. 07 + 0. 08 weeks, r = 0. 433, P <0. 0001). And the D/L did not vary significantly throughout pregnancy(D/L = 0. 21 0.04, r = 0. 115, P = 0.08). Therefore, the D value of normal fetal CS is less than 3.9 mm and D/L is less than 0.3 throughout pregnancy (20-40 gestational weeks). Conclusions The values of D and D/L of fetal CS in prenatal echocardiography might be useful and important parameters for fetal cardiac or extracardiac anomaly.

Objective To compare success and complication rate of cordocentesis (CC) with intrahepatic umbilical vein sampling (IUVS) under the guidance of ultrasonography in ovine fetus. Methods Twenty near-term singleton pregnant ewes were randomly divided into CC group and IUVS group (each n=10). All of the ewes underwent CC or IUVS in ovine fetus guided with ultrasonography. Success and complication rate of CC and IUVS were calculated. Results Success rates of IUVS on the first, less than 3 times and 5 times attempt was 32.00%, 68.00% and 84.00%, respectively, higher than that of CC (15.00%, 40.00% and 75.00%, respectively, P<0.05). Sever complication rates of IUVS in comparison with CC was not statistically different (P>0.05). Conclusion Fetal IUVS may be a reasonable option to obtain fetal intravascular access and facilitate therapeutic intervention.

BACKGROUND: A skull defect is inevitable after decompression treatment for traumatic brain injury. Titanium mesh as the most recognized skull repair material has good biocompatibility and has been widely used in clinical practice. However, the timing for skull repair after brain injury is still in dispute.OBJECTIVE: To compare the changes of brain perfusion and the recovery of neurological function in patients with skull defects before and after early and late-stage titanium mesh repair based on CT perfusion technique.METHODS: This was a single-center, prospective, observational clinical trial that was completed at the Taihe Hospital,Hubei University of Medicine in Hubei Province, China. Eighty-six patients with craniocerebral injury who had undergone decompression with removal of bone flap from January 2013 to January 2016 were recruited and subjected to skull repair using titanium mesh. All the patients were randomized into two groups: test group (n=40) with early skull repair within 1-3 months after decompression and control group (n=46) with late-stage skull repair within 6-12 months after decompression. CT perfusion technology was used to observe changes of brain perfusion at 3 days operatively and at 10 days postoperatively. The Barthel index was evaluated at 30 days postoperatively. The trial was registered with ClinicalTrial.gov (identifier: NCT03222297) on July 12th, 2017. The study protocol was approved by the Ethics Committee of Taihe Hospital with the approval No. 2012 (08), and performed in accordance with the Declaration of Helsinki,formulated by the World Health Organization and the hospital's ethical requirements for human research. All the patients and their families were voluntary to participate in the trial, were fully informed of the trial process, and then signed the informed consent prior to the initialization of the trial.RESULTS AND CONCLUSION: The postoperative cerebral blood volume and cerebral blood flow at the parietal cortex on the side of skull defect and at the cortex in the defect region were significantly higher in the two group than the baseline (P < 0.05), while the time to peak was lower than the baseline (P < 0.05). Compared with the control group,significantly higher cerebral blood volume and cerebral blood flow as well as shorter time to peak were observed in the test group (P < 0.05). The Barthel index of the test group was also significantly higher than that of the control group at 30 days postoepratively (P < 0.05). Overall, early skull repair with titanium mesh is helpful to improve the cerebral blood perfusion at the affected side and the recovery of neurological function. In addition, CT perfusion technology is a safe and effective method to monitor hemodynamic changes in the brain.
