normal morphometry of fetal posterior fossa at midtrimester brainstem Tentorium angle and brainstem vermis angle
Prenatal Diagnosis, 2012Co-Authors: E Contro, Francesca De Musso, Antonio Farina, Roberto Conturso, Paola Bonasoni, G Salsi, A Youssef, Nicola Rizzo, G PiluAbstract:Objective To standardize the evaluation of normal Tentorium insertion and normal rotation of the cerebellar vermis over the brainstem, using two novel measurements: the brainstem–Tentorium angle (BT angle) and the brainstem–vermis angle (BV angle). We also aimed to test the reproducibility of these measurements. Methods Prospective observational study including normal fetuses at routine anomaly scan with confirmed normal follow-up. Three-dimensional volumes of the fetal head were acquired starting from standard trans-cerebellar views. In the sagittal plane, obtained by multiplanar reconstruction, the angle between the brainstem and the Tentorium insertion in the fetal skull, and between the brainstem and the lower edge of the vermis were measured twice by two independent operators. Intraobserver and interobserver variations were calculated. Results Eighty cases were included. The estimated BT and BV angles lie in a wide interval among normal midtrimester fetuses with a median value (min–max) of 25.65 (20.13–47.39) and 9.29 (3.87–19.36) respectively. Intraobserver and interobserver variation were good for both measurements. Conclusion The BT and BV angle may be of help in assessing the fetal posterior fossa at midgestation and gives a standardized and reproducible measurement of normal Tentorium insertion and normal rotation of the cerebellar vermis over the brainstem. © 2012 John Wiley & Sons, Ltd.

clinical study of Tentorium cerebelli hiatus incision for prevention of cerebral infarction after severe traumatic brain injury
Journal of Traumatic Surgery, 2014Co-Authors: Pan LiangzAbstract:Objective To explore the value of Tentorium cerebelli hiatus incision in preventing cerebral infarction after operation for severe traumatic brain injury.Methods Totally 120 patients with severe traumatic brain injury who were admitted into our hospital from Jan.2011 to Jan.2013 were divided into 2 groups:treatment group(n =60) treated with the removal of hematomas,decompressive craniotomy and Tentorium cerebelli hiatus incision,and control group(n = 60) with the same treatment except for Tentorium cerebelli hiatus incision.All patients underwent head CT after operation.The incidence of cerebral infarction,intracranial pressure index,the dosage of mannitol and Glasgow Outcome Scale were compared and statistically analyzed.Results The incidence of cerebral infarction(6.7%),intracranial pressure index(11.30 ± 2.62),the application times of mannitol(34.00 ± 2.90) in the treatment group were lower than those in the control group[13.3%,(15.70 ± 2.65),(45.38 ± 3.42),respectively](P 0.05).Glasgow Outcome Scale was obviously better in the treatment group than that in the control group(P 0.05).Conclusion Tentorium cerebelli hiatus incision is a good approach for the treatment of severe traumatic brain injury,which can reduce the incidence of cerebral infarction and improve patients' survival and prognosis.
