Severe traumatic brain injury (sTBI) has a high mortality and disability rate, making it a difficult issue and hot topic in neurosurgery. Controlled decompression is an important technique in the treatment of sTBI combined with intracranial hypertension, which can reduce the ischemia-reperfusion injury to the nervous tissue and intracranial vessel and can significantly lower the incidence of complications related to decompressive craniectomy. However, the effects of the controlled decompression technique have been affected by different understandings of the technique and nonstandard surgical procedures in clinical practice. For this purpose, the authors discussed the concept of controlled decompression technique, its indications and the key problems during operation so as to standardize the surgical procedures and improve the therapeutic effects of controlled decompression technique in the treatment of sTBI.

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.

Objective:To explore the application value of ventricular intracranial pressure monitoring (V-ICPM) in the treatment of unilateral temporal lobe cerebral contusion.Methods:A retrospective cohort study was conducted to analyze the clinical data of 295 patients with unilateral temporal lobe cerebral contusion admitted to 904th Hospital of PLA Joint Support Force from January 2014 to August 2021, including 172 males and 123 females; aged 14-78 years [(46.3±14.7)years]. V-ICPM was used in 136 patients (V-ICPM group), who received surgical or non-surgical treatment according to the monitoring, while not in 159 patients (non-V-ICPM group), who received routine surgery or non-surgical treatment. The two groups were compared in terms of the rates of intracranial hematoma clearance by craniotomy, decompressive craniectomy (DC) and dehydration and osmotic therapy during hospitalization, use time of 20% mass fraction of mannitol and 30 g/L hypertonic salt, displacement rate of brain midline structure of head CT≥10 mm after discharge, rate of intracranial infection, hydrocephalus and epilepsy, and Glasgow Outcome Scale (GOS) at 6 months after discharge.Results:All patients were followed up for 6-12 months [(8.9±2.1)months]. During hospitalization, the rate of intracranial hematoma clearance by craniotomy and the rate of DC in V-ICPM group were 35.3% (48/136) and 8.1% (11/136), lower than 47.2% (75/159) and 22.0% (35/159) in non-V-ICPM group ( P<0.05 or 0.01). There was no significant difference between the two groups in the rate of dehydration and osmotic therapy or the use time of mannitol (all P>0.05). The use time of hypertonic salt in V-ICPM group was (7.2±2.5)days, more than (4.1±1.8)days in non-V-ICPM group ( P<0.05). After discharge, the displacement rate of brain midline structure of head CT in V-ICPM group was 29.4% (40/136), lower than 42.8% (68/159) in non-V-ICPM group ( P<0.05). There was no significant difference between the two groups in the rate of intracranial infection, hydrocephalus and epilepsy (all P>0.05). Six months after discharge, the good rate of GOS in V-ICPM group was 91.2% (124/136), significantly better than 81.8% (130/159) in non-V-ICPM group ( P<0.05). Conclusion:For unilateral temporal lobe cerebral contusion, V-ICPM is associated with reduced rate of craniotomy exploration and DC, decreased incidence of complications and improved prognosis of the patients in spite of longer use time of hypertonic salt.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Objective:To systematically evaluate the effect of serum albumin content on the prognosis of patients with severe traumatic brain injury (TBI).Methods:PubMed, Embase, Cohrane Library, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), China Journals Full-text Database (CJFD), VIP database and Wanfang Database were used for retrieval from inception to November 10, 2020. Through retrieving Chinese and English literatures, relevant studies on serum albumin content in different types of TBI patients and in severe TBI patients with different prognostic results were included. The difference of serum albumin content in patinets with severe TBI with healthy people and patients with mild illness TBI, and the difference in serum albumin content between patients with good and poor prognosis of severe TBI were observed. At the same time, the differences in serum albumin content between subgroups were evaluated by subgroup analysis of the authors' country, literature quality and severity of the control group according to characteristics that might cause heterogeneity.Results:A total of 9 articles were included in this study, including 1, 438 study subjects. The serum albumin content in patients with severe TBI was significantly lower than that in healthy individuals and patients with mild TBI ( WMD=-6.42, 95% CI -9.95--2.80, Z=3.82, P<0.01). Subgroup analysis showed that serum albumin content in patients with severe TBI was significantly lower than that in healthy people ( WMD=-8.77, 95% CI-10.28--7.25, Z=11.37, P<0.01). Serum albumin content in patients with severe TBI was significantly lower than that in patients with mild TBI ( WMD=-4.07, 95% CI -9.53 -1.39, Z=1.46, P<0.05), suggesting that mild TBI patients are the main source of heterogeneity. The serum albumin content in patients with poor prognosis of severe TBI was significantly lower than that in patients with good prognosis of severe TBI ( WMD=-4.48, 95% CI-7.39--1.58, Z=3.02, P<0.01). Conclusion:Serum albumin content in patients with severe TBI is significantly lower than that in healthy individuals as well as in patients with mild TBI, and low albumin content indicates a poor prognosis in patients with severe TBI.

Objective To investigate the prognostic influence factors of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion. Methods From March 2015 to March 2017,222 consecutive patients with acute anterior circulation macrovascular occlusion admitted to the Department of Neurosurgery,the 101stHospital of People′s Liberation Army and the Nanjing Jinling Hospital were enrolled retrospectively.They were all confirmed by DSA and were treated with Solitaire stent thrombectomy. According to the modified Rankin Scale(mRS) scores at 90 d after treatment,they were divided into a good prognosis group (0-2,n=120) and a poor prognosis group (3-6,n =102). The baseline data and clinical data of the two groups of patients were analyzed,including the risk factors for cardiocerebrovascular diseases,baseline National Institutes of Health Stroke Scale (NIHSS) score,occlusion sites (internal carotid artery or middle cerebral artery occlusion),collateral compensatory,onset to puncture time, operation time,onset to recanalization median time,recanalization status,preoperative Alberta stroke programme early CT score(ASPECTS),and symptomatic cerebral hemorrhage,and then further multivariate logistic regression analysis was conducted for the prognostic factors of patients. Results (1) The rate of good prognosis was 54.1% (120/222).There were no significant differences in patients′ age,NIHSS at admission,ASPECTS at admission,sex,hypertension,occlusion site,and rate of good collateral branches in both groups(all P<0.05).There were no significant differences in other baseline data (all P >0. 05). (2) Onset to puncture time and onset to successful recanalization median time of the patients in good prognosis group was lower than that of the poor prognosis group (182 [138,230]min vs.236[170,305]min, 237[175,269]min vs.288[223,367]min).The proportion of successful recanalization was higher than that of the poor prognosis group (98.3% [118/120] vs.78.4% [80/102]).The proportion of postoperative symptomatic intracerebral hemorrhage was lower than that of the poor prognosis group (2.5% [3/120] vs.21.6% [22/102]).There was significant difference between the two groups (all P <0.01). There was no significant difference in operative time between the two groups (P >0.05). (3)In the single factor analysis,the parameter of P <0.05 was used as an independent variable,and prognosis was used as a dependent variable,multivariate logistic regression analysis showed that the increased age (OR,1.096,95% CI 1.050-1.144),history of hypertension (OR,8.401,95% CI 2.960-23.845),increased baseline NIHSS score (OR,1.071,95% CI 1.007-1.138),prolonged onset to successful recanalization time (OR,1.019,95% CI 1.003-1.035),symptomatic intracerebral hemorrhage after procedure (OR,18.110,95% CI 4.656-70.434) were all the risk factors for poor prognosis(all P<0.05);higher ASPECTS score at admission(OR,0.641,95% CI 0.451-0.911) and successful recanalization (OR,0.127,95% CI 0.024-0.664) were all the protective factors of good prognosis (all P<0.05). Conclusions Higher ASPECTS at admission and successful recanalization were the protective factors of poor prognosis of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion.Increased age,history of hypertension,increased baseline NIHSS score,prolonged onset to successful recanalization time,and symptomatic intracerebral hemorrhage after procedure were the risk factors for poor prognosis of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion.

Objective To observe the changes of cerebral vascular morphology and blood flow after craniocerebral trauma so as to investigate the role of transcranial Doppler sonography (TCD) combined with CT angiography (CTA) in judgment of the operative effect and prognosis of severe craniocerebral trauma.MethodsA total of 56 patients with craniocerebral trauma were monitored dynamically by using TCD before and after surgery.Dynamic CTA of head was also performed by using 128-slice spiral CT.Results TCD and CTA indicated that both the cerebral blood flow and vascular morphologychanged after craniocerebral trauma.CTA manifested mainly the vascular displacement or angiostegnosis and TCD showed mainly the high-resistance blood flow,indicating good operative effect.For the patients with vasospasm,the TCD manifested high-resistance flow (relatively good operative effect) or nail flow(mostly poor operative effect). The patients with vascular occlusion were associated with nail flow on TCD,with poor operative effect.ConclusionsTCD shows the velocity of cerebral blood flow and CTA shows the morphological change of cerebral vessels.Thereby,the combination of TCD and CTA can effectively judge the cerebral perfusion and provide a promising way for validating the operative effect and prognosis of craniocerebral trauma.
