Background： During craniotomies using the transpetrosal-presigmoid approach, exposure of the sigmoid sinus remains an essential but hazardous step. In such procedures, accurate localization of the anterosuperior point of the transverse-sigmoid sinus junction （ASTS） is very important lbr reducing surgical morbidity. This study aimed to create an accurate and practical method for identifying the ASTS. Methods： On the lateral surfaces of 40 adult skulls （ 19 male skulls and 21 female skulls）, a rectangular coordinate system was defined to measure the x and y coordinates of two points： the ASTS and the squamosal-parietomastoid suture junction （SP）. With the coordinate system, the distribution characteristics of the ASTS were statistically analyzed and the differences between the ASTS and SP were investigated. Results： For ASTS-x, significant differences were found in different sides （P =0.020）; the ASTS-x in male skulls was significantly higher on the right side （P =0.017）; there was no significant difference between the sides in female skulls. There were no significant differences in gender or interaction of gender and side for ASTS-x, and for ASTS-y, there were no significant differences in side, gender, or interaction of gender and side. For both sides combined, the mean ASTS-x was significantly higher than the mean SP-x （P = 0.003） and the mean ASTS-y was significantly higher than the mean SP-y （P = 0.011 ）. Conclusions： This reference coordinate system may be an accurate and practical method for identifying the ASTS during presigmoid craniotomy. The SP might be difficult to find during presigmoid craniotomy and, therefore, it is not always a reliable landmark for defining the ASTS.

Background: Although technically regarded as a simple procedure, titanium mesh cranioplasty could lead to various surgical complications, including postoperative implant exposure. However, there is little data available on the occurrence and risk factors of this complication in the pediatric population. Cases presentation: Two pediatric male patients, one 12-year-old and one 7-year-old, had decompressive craniectomy after traumatic brain injuries and subsequent cranioplasty with titanium mesh. However, both patients had skin defects developed gradually at the scalp adjacent to the surgical incisions, 11 and 7 months after cranioplasty, respectively. Implants removal surgeries were then delivered and, during the operation, some bone debris were found just beneath the skin defects in both patients. Because microbiological culture results of the exudations were negative, in addition to the long interval between cranioplasty and developments of skin defects, surgical infections might not be major causes of the observed titanium implants exposures. On the other hand, local osteogenesis and impaired scalp blood supply might contribute to their occurrence. Conclusions: Efforts should be made to achieve complete clearance of bone debris and protect scalp blood supply during the initial decompressive craniectomy in order to minimize the risks of subsequent titanium mesh exposures.

Purpose： Posterior fossa epidural hematomas （PFEDH） are uncommon in children but usually require timely surgical intervention due to the risk of life-threatening brainstem compression. We attempt to make the surgical procedure less invasive by treating selected pediatric patients with trephination minicraniectomy. Methods： We retrospectively reviewed the clinical courses, radiological findings, surgical procedures, and prognoses of the pediatric patients who were treated in our departments for traumatic PFEDH from January 2010 to January 2015. Results： During this period, a total of 17 patients were surgically treated for PFEDH and 7 were managed with trephination mini-craniectomy for hematoma evacuation. The outcomes were good in all 7 patients as evaluated with Glasgow Outcome Score. There was no mortality in this series. The on average 30-month clinical follow-up showed that patients experienced satisfactory recoveries without complications. Conclusion： Our results suggest that trephination mini-craniectomy is a safe surgical technique for selected PFEDH patients with moderate hematoma volume and stabilized neurological functions. However, standard craniectomy is recommend when there are rapid deteriorations in patients＇ neurological functions or the hematomas are large and exerted severe mass effects.

目的探讨钆喷酸葡胺作为胃肠道阴性对比剂在3.0T磁共振胰胆管成像中的应用价值。方法对39例病人分别在口服钆喷酸葡胺前后进行磁共振胰胆管成像检查,得到两组对照图像,请放射科3位高年资医生对两组图像进行评估后行统计学分析。结果采用χ2检验分析,χ2值为62,P<0.001,两组差异具有显著性意义。结论口服钆喷酸葡胺后行磁共振胰胆管成像,图像中胃肠道液体信号几乎完全被抑制,既经济又方便,在磁共振胰胆管成像中更应该值得推广应用。
