ABSTRACT
Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.
ABSTRACT
Spinal cord injury (SCI) is a central nervous system(CNS)-related disorder. There is yet no successful treatment for this issue at present. Cell-based therapies have been explored for SCI restoration, including the use of pluripotent human stem cells, and a number of adult-derived stem and mature cells such as mesenchymal stem cells, olfactory ensheathing cells. However, cell transplantation is often hampered by the poor cell survival in the treatment of spinal cord injuries. Alternatively, the therapeutic role of different cells has been used in tissue engineering approaches by engrafting cells with biomaterials. The latter have the advantages of physically mimicking the CNS tissue, while promoting a more permissive environment for cell survival, growth, and differentiation. The roles of both cell transplantation and biomaterial-based therapies as single therapeutic approaches for SCI repair will be discussed in this review.
ABSTRACT
Objective To compare the effects of standard decompressive craniectomy (DC) vs.combined cisternostomy on severe traumatic brain injury (STBI).Methods Seventy-two patients with severe brain injury were divided into standard decompressive craniectomy group (control group,n=34) and DC combined cisternostomy group (treatment group,n=38).The clinical parameters from pre-and post-surgery were compared between the two groups.Results There was no statistical difference in clinical data including gander,age,injury causes,GSC score,Helsinki CT score and operative opportunity between two groups before surgery (P＞0.05).The treatment group was inferior in the duration of decompression (2.8±0.4 h vs.2.5±0.3 h,P＜0.05) relative to control treatment group.However,treatment group were superior to control group in the mean time of admission in neuro-intensive care unit (5.54±3.09 d vs.7.24±2.74 d,P＜0.01),the cumulative time of intracranial pressure (ICP) more than 20 nmHg within seven days after surgery(23.2±4.4 h vs.56.8±8.3 h,P＜0.01),Helsinki CT scores at postoperative day (3(2,5) vs.5(2,9),P＜ 0.01)and Glasgow Outcome Scores (GOS) at 3 month after surgery (P＜0.01).Conclusion DC combined with cisternostomy for STBI is significantly better than standard decompressive craniectomy,which is worth further study by multicenter clinical trials.
ABSTRACT
Objective To explore the significance of surgical resection for the pineal region tumor,the extent of tumor resection,the surgical approaches and treatment measures of hydrocephalus.Methods Twentythree patients diagnosed of pineal region cancer were recruited for this study.Thirteen patients received ventriculo-peritoneal shunt(V-P),during which 7 cases received intraoperative end-plate colostomy.Two of the 13 cases received a second V-P procedure.Another 13 cases received operation by corpus callosum- septum-Dome Room-the third ventricle approach to remove the tumor; Eight cases underwent the tumor resection by suboccipital supratentorial approach (Poppen approach )and 2 cases underwent the tumor resection by the infratentorial cerebellar approach( Krause approach).Results Total tumor resection was performed in 11 cases,subtotal or major total resection in 8 cases and partial resection in 4 cases.Nine cases underwent postoperative radiotherapy alone,8 receiving radiotherapy plus chemotherapy,and 6 cases receiving neither radiotherapy nor chemotherapy.Two cases died during treatment.Conclusion Though it is not practicable to completely remove the germ cell tumor in patients with relatively large tumors,cerebrospinal fluid circulation pathways should be reestablished,including ventriculo-peritoneal shunt,colostomy from the end of the third ventricle to the end plate.If tumors are not too large,they would be easy to be removed.The effects on the surrounding brain tissue would not be much significant.If the connection of Ⅲ,V ventricles were normal,the patient may not need shunt or colostomy.Radiotherapy and chemotherapy can be given to this kind of patients after the surgery.To improve the efficacy,other types of tumors,expecially the benign tumors,should be totally removed.
