Endoscopic-assisted removal of bilateral traumatic intracerebral hemorrhage: A case report. Surg Neurol Int 2023; 14:288. [PMID: 37680938 PMCID: PMC10481816 DOI: 10.25259/sni_268_2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 07/31/2023] [Indexed: 09/09/2023] Open
Abstract
Background Decompressive craniectomy or craniotomy is an effective method for reducing intracranial pressure in patients with traumatic brain injury. However, contralateral intracranial hematoma is a rare but serious complication. Recently, the endoscopic technique has been described as a minimally invasive, safe, and effective treatment for intracranial hematoma evacuation. To the best of our knowledge, no technical report has described bilateral traumatic intracerebral hemorrhage (TICH) evacuation using a neuroendoscope. Case Description A 62-year-old man was admitted to the hospital after a fall due to intoxication. His initial Glasgow Coma Scale (GCS) score was 14. Initial computed tomography (CT) revealed a right temporal skull fracture, bilateral frontal and right temporal tip contusions, and acute subdural hematoma. During admission, his condition deteriorated to a GCS score of 6 points, and follow-up CT showed hemorrhagic progression of left frontal and right temporal contusion with midline shift and brainstem compression. Emergency surgery was performed for TICH in the left frontal lobe and right temporal lobe. A burr hole was made in each of the left frontal and right temporal regions, and we used a neuroendoscope to assist in the evacuation of the hematoma. Postoperative CT showed adequate evacuation of the hematoma. The patient regained consciousness and was discharged after 2 months. Conclusion Bilateral TICH was rapidly and sequentially removed by burr-hole craniotomy and endoscopic hematoma evacuation without rapid decompression by craniotomy. The hematoma did not increase. This report demonstrates that the endoscopic-assisted technique allows the safe treatment of bilateral TICH.

A Clinical Predictive Nomogram for Traumatic Brain Parenchyma Hematoma Progression. Neurol Ther 2022; 11:185-203. [PMID: 34855160 PMCID: PMC8857351 DOI: 10.1007/s40120-021-00306-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Accepted: 11/22/2021] [Indexed: 02/05/2023] Open
Abstract
INTRODUCTION Acute traumatic intraparenchymal hematoma (tICH) expansion is a major cause of clinical deterioration after brain contusion. Here, an accurate prediction tool for acute tICH expansion is proposed. METHODS A multicenter hospital-based study for multivariable prediction model was conducted among patients (889 patients in a development dataset and 264 individuals in an external validation dataset) with initial and follow-up computed tomography (CT) imaging for tICH volume evaluation. Semi-automated software was employed to assess tICH expansion. Two multivariate predictive models for acute tICH expansion were developed and externally validated. RESULTS A total of 198 (22.27%) individuals had remarkable acute tICH expansion. The novel Traumatic Parenchymatous Hematoma Expansion Aid (TPHEA) model retained several variables, including age, coagulopathy, baseline tICH volume, time to baseline CT time, subdural hemorrhage, a novel imaging marker of multihematoma fuzzy sign, and an inflammatory index of monocyte-to-lymphocyte ratio. Compared with multihematoma fuzzy sign, monocyte-to-lymphocyte ratio, and the basic model, the TPHEA model exhibited optimal discrimination, calibration, and clinical net benefits for patients with acute tICH expansion. A TPHEA nomogram was subsequently introduced from this model to facilitate clinical application. In an external dataset, this device showed good predicting performance for acute tICH expansion. CONCLUSIONS The main predictive factors in the TPHEA nomogram are the monocyte-to-lymphocyte ratio, baseline tICH volume, and multihematoma fuzzy sign. This user-friendly tool can estimate acute tICH expansion and optimize personalized treatments for individuals with brain contusion.

Surgical application of endoscopic-assisted minimally-invasive neurosurgery to traumatic brain injury: Case series and review of literature. J Formos Med Assoc 2021; 121:1223-1230. [PMID: 34865948 DOI: 10.1016/j.jfma.2021.11.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 11/01/2021] [Accepted: 11/17/2021] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND/PURPOSE Adequate decompression is the primary goal during surgical management of patients with traumatic brain injury (TBI). Therefore, it may seem counterintuitive to use minimally-invasive strategies to treat these patients. However, recent studies show that endoscopic-assisted minimally-invasive neurosurgery (MIN) can provide both adequate decompression (which is critical for preserving viable brain tissue) and maximize neurological recovery for patients with TBI. Hence, we reviewed the pertinent literature and shared our experiences on the use of MIN. METHODS This was a retrospective multi-center study. We collected data of 22 TBI patients receiving endoscopic-assisted MIN within 72 hours after the onset, with Glasgow Coma Scale (GCS) scores of 6-14 and whose hemorrhage volume ranging from 30 to 70 mL. RESULTS We have applied MIN techniques to a group of 22 patients with traumatic ICH (TICH), epidural hematoma (EDH), and subdural hematoma (SDH). The mean pre-operative GCS score was 7.5 (median 7), and mean hemorrhage volume was 57.14 cm3 Surgery time was shortened with MIN approaches to a mean of 59.6 min. At 6-month follow-up, the mean GCS score had improved to 12.3 (median 15). By preserving more normal brain tissue, MIN for patients with TBI can result in beneficial effects on recoveries and neurological outcomes. CONCLUSION Endoscopic-assisted MIN in TBI is safe and effective in a carefully selected group of patients.

Abstract
PURPOSE OF REVIEW The surgical management of trauma-related intracranial hemorrhage is characterized by marked heterogeneity. Large prospective randomized trials have generally been prohibited by the ubiquity of concordant pathology, diversity of trauma systems, and paucity of clinical equipoise among providers. RECENT FINDINGS To date, the results of retrospective studies and surgeon preference have driven the indications, modality, extent, and timing of surgical intervention in the global neurosurgical community. With advances in our understanding of the pathophysiology of hemorrhagic TBI and the advent of novel surgical techniques, a reevaluation of surgical indication, timing, and approach is warranted. In this way, we can work to optimize surgical outcomes, achieving maximal functional recovery while minimizing surgical morbidity.

Role of repeat CT in mild to moderate head injury: an institutional study. Neurosurg Focus 2020; 47:E2. [PMID: 31675712 DOI: 10.3171/2019.8.focus19527] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Accepted: 08/20/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Patients with traumatic brain injury (TBI) often undergo repeat head CT scans to identify the possible progression of injury. The objective of this study is to evaluate the need for routine repeat head CT scans in patients with mild to moderate head injury and an initial positive abnormal CT scan. METHODS This is a retrospective study of patients presenting to the emergency department from January 2016 to December 2017 with Glasgow Coma Scale (GCS) scores > 8 and an initial abnormal CT scan, who underwent repeat CT during their in-hospital medical management. Patients who underwent surgery after the first CT scan, had a GCS score < 9, or had a normal initial CT scan were excluded. Demographic, medical history, and physical examination details were collected, and CT scans were reviewed. Radiological deterioration, neurological deterioration, and/or the need for neurosurgical intervention were the primary outcome variables. RESULTS A total of 1033 patients were included in this study. These patients underwent at least two CT scans on an inpatient basis. Of these 1033 patients, 54.1% had mild head injury and 45.9% had moderate head injury based on GCS score at admission. The most common diagnosis was contusion (43.8%), followed by extradural hematoma (28.8%) and subdural hematoma (26.6%). A total of 2636 CT scans were performed for 1033 patients, with a mean of 2.55 per patient. Of these, 25 (2.4%) had neurological deterioration, 90 (8.7%) had a progression of an existing lesion or appearance of a new lesion on repeat CT, and 101 (9.8%) required neurosurgical intervention. Seventy-five patients underwent surgery due to worsening of repeat CT without neurological deterioration, so the average number of repeat CT scans required to identify one such patient was 21.3. On multiple logistic regression, GCS score at admission (p = 0.024), abnormal international normalized ratio (INR; p < 0.001), midline shift (p = 0.005), effaced basal cisterns (p < 0.001), and multiple hemorrhagic lesions (p = 0.010) were associated with worsening of repeat CT, neurological deterioration, and/or need for neurosurgical intervention. CONCLUSIONS The role of routine repeat head CT in medically managed patients with head injury is controversial. The authors have tried to study the various factors that are associated with neurological deterioration, radiological deterioration, and/or need for neurosurgical intervention. In this study the authors found lower GCS score at admission, abnormal INR, presence of midline shift, effaced basal cisterns, and multiple lesions on initial CT to be significantly associated with the above outcomes.

Abstract
BACKGROUND Failure of cerebral autoregulation and progression of intracranial lesion have both been shown to contribute to poor outcome in patients with acute traumatic brain injury (TBI), but the interplay between the two phenomena has not been investigated. Preliminary evidence leads us to hypothesize that brain tissue adjacent to primary injury foci may be more vulnerable to large fluctuations in blood flow in the absence of intact autoregulatory mechanisms. The goal of this study was therefore to assess the influence of cerebrovascular reactivity measures on radiological lesion expansion in a cohort of patients with acute TBI. METHODS We conducted a retrospective cohort analysis on 50 TBI patients who had undergone high-frequency multimodal intracranial monitoring and for which at least two brain computed tomography (CT) scans had been performed in the acute phase of injury. We first performed univariate analyses on the full cohort to identify non-neurophysiological factors (i.e., initial lesion volume, timing of scan, coagulopathy) associated with traumatic lesion growth in this population. In a subset analysis of 23 patients who had intracranial recording data covering the period between the initial and repeat CT scan, we then correlated changes in serial volumetric lesion measurements with cerebrovascular reactivity metrics derived from the pressure reactivity index (PRx), pulse amplitude index (PAx), and RAC (correlation coefficient between the pulse amplitude of intracranial pressure and cerebral perfusion pressure). Using multivariate methods, these results were subsequently adjusted for the non-neurophysiological confounders identified in the univariate analyses. RESULTS We observed significant positive linear associations between the degree of cerebrovascular reactivity impairment and progression of pericontusional edema. The strongest correlations were observed between edema progression and the following indices of cerebrovascular reactivity between sequential scans: % time PRx > 0.25 (r = 0.69, p = 0.002) and % time PAx > 0.25 (r = 0.64, p = 0.006). These associations remained significant after adjusting for initial lesion volume and mean cerebral perfusion pressure. In contrast, progression of the hemorrhagic core and extra-axial hemorrhage volume did not appear to be strongly influenced by autoregulatory status. CONCLUSIONS Our preliminary findings suggest a possible link between autoregulatory failure and traumatic edema progression, which warrants re-evaluation in larger-scale prospective studies.

Abstract
Objective The principle operation of acute subdural hematoma (ASDH) is a craniotomy with hematoma removal, but a trephination with hematoma evacuation may be another method in selected cases. Trephine drainage was performed for ASDH patients in subacute stage using urokinase (UK) instillation, and its results were evaluated. Methods Between January 2016 and December 2018, the trephine evacuation using UK was performed in 9 patients. The interval between injury and operation was from 1 to 2 weeks. We underwent a burr hole trephination with drainage initially, and waited until the flow of liquefied hematoma stopped, then instilled UK for the purpose of clot liquefaction. Results The mean age of patients was 71.6 years (range, 38-90 years). The cause of ASDH was trauma in 8 cases, and supposed a complication of anticoagulant medication in 1 case. Four out of 8 patients took antiplatelet medications and one of them was a chronic alcoholism. The range of the Glasgow Coma Scale score before surgery was from 13 to 15. Most of patients, main symptom was headache at admission. The Glasgow Outcome Scale score was 5 in 8 cases and 3 in 1 case. Conclusion It is thought to be a useful operation method in selected patients with ASDH that the subdural drainage in subacute stage with UK instillation. This method might be another useful option for the patients with good mental state regardless of age and the patients with a risk of bleeding due to antithrombotic medications.

Abstract
OBJECTIVE Traumatic intracerebral hemorrhage (TICH) represents approximately 13%-48% of the lesions after a traumatic brain injury (TBI), and hemorrhagic progression (HP) occurs in 38%-63% of cases. In previous studies, decompressive craniectomy (DC) has been characterized as a risk factor in the HP of TICH; however, few studies have focused exclusively on this relationship. The object of the present study was to analyze the relationship between DC and the growth of TICH and to reveal any correlation with the size of the craniectomy, degree of cerebral parenchymal herniation (CPH), or volumetric expansion of the TICH. METHODS The authors retrospectively analyzed the records of 497 adult patients who had been consecutively admitted after suffering a severe or moderate closed TBI. An inclusion criterion was presentation with one or more TICHs on the initial or control CT. Demographic, clinical, radiological, and treatment variables were assessed for associations. RESULTS Two hundred three patients presenting with 401 individual TICHs met the selection criteria. TICH growth was observed in 281 cases (70.1%). Eighty-two cases (20.4%) underwent craniectomy without TICH evacuation. In the craniectomy group, HP was observed in 71 cases (86.6%); in the noncraniectomy group (319 cases), HP occurred in 210 cases (65.8%). The difference in the incidence of HP between the two groups was statistically significant (OR 3.41, p < 0.01). The mean area of the craniectomy was 104.94 ± 27.5 cm2, and the mean CPH distance through the craniectomy was 17.85 ± 11.1 mm. The mean increase in the TICH volume was greater in the groups with a craniectomy area > 115 cm2 and CPH > 25 mm (16.12 and 14.47 cm3, respectively, p = 0.01 and 0.02). After calculating the propensity score (PS), the authors followed three statistical methods-matching, stratification, and inverse probability treatment weighting (IPTW)-thereby obtaining an adequate balance of the covariates. A statistically significant relationship was found between HP and craniectomy (OR 2.77, p = 0.004). This correlation was confirmed with the three methodologies based on the PS with odds greater than 2. CONCLUSIONS DC is a risk factor for the growth of TICH, and there is also an association between the size of the DC and the magnitude of the volume increase in the TICH.

Abstract
Secondary injuries are associated with bad outcomes in the case of severe traumatic brain injury (sTBI). Patients with a Glasgow Coma Scale (GCS) < 9 should undergo pre-hospital intubation (PHI). There is controversy about whether PHI is beneficial. The aim of this study was to estimate the effect of PHI in patients after sTBI. A multicenter, prospective cohort study was performed in Switzerland, including 832 adults with sTBI. Outcomes were death and impaired consciousness at 14 days. Associations between risk factors and outcomes were assessed with univariate and multivariate Cox models for survival, and univariate and multivariate regression models for impaired consciousness. Potential risk factors were age, GCS on scene, pupil reaction, Injury Severity Score (ISS), PHI, oxygen administration, and type of admission to trauma center. Age, GCS on scene < 9, abnormal pupil reaction and ISS ≥ 25 were associated with mortality. GCS < 9 and ISS ≥ 25 were correlated with impaired consciousness. PHI was overall not associated with short-term mortality and consciousness. However, there was a significative interaction with PHI and major trauma. PHI improves outcome from patients with sTBI and an ISS ≥ 25.

Abstract
The optimal management of mild traumatic brain injury (TBI) patients with injuries identified by computed tomography (CT) brain scan is unclear. Some guidelines recommend hospital admission for an observation period of at least 24 h. Others argue that selected lower-risk patients can be discharged from the Emergency Department (ED). The objective of our review and meta-analysis was to estimate the risk of death, neurosurgical intervention, and clinical deterioration in mild TBI patients with injuries identified by CT brain scan, and assess which patient factors affect the risk of these outcomes. A systematic review and meta-analysis adhering to PRISMA standards of protocol and reporting were conducted. Study selection was performed by two independent reviewers. Meta-analysis using a random effects model was undertaken to estimate pooled risks for: clinical deterioration, neurosurgical intervention, and death. Meta-regression was used to explore between-study variation in outcome estimates using study population characteristics. Forty-nine primary studies and five reviews were identified that met the inclusion criteria. The estimated pooled risk for the outcomes of interest were: clinical deterioration 11.7% (95% confidence interval [CI]: 11.7%-15.8%), neurosurgical intervention 3.5% (95% CI: 2.2%-4.9%), and death 1.4% (95% CI: 0.8%-2.2%). Twenty-one studies presented within-study estimates of the effect of patient factors. Meta-regression of study characteristics and pooling of within-study estimates of risk factor effect found the following factors significantly affected the risk for adverse outcomes: age, initial Glasgow Coma Scale (GCS), type of injury, and anti-coagulation. The generalizability of many studies was limited due to population selection. Mild TBI patients with injuries identified by CT brain scan have a small but clinically important risk for serious adverse outcomes. This review has identified several prognostic factors; research is needed to derive and validate a usable clinical decision rule so that low-risk patients can be safely discharged from the ED.

Abstract
OBJECTIVE A subdural drain using urokinase after a burr hole hematoma evacuation was performed for subacute subdural hematoma (SASDH), and its effectiveness and safety in elderly patients were evaluated. METHODS Between January 2013 and May 2015, subdural drains using urokinase after burr hole hematoma evacuation were performed in 19 elderly patients. The inclusion criteria were as follows: 1) a subdural hematoma occurring between 4 and 20 days after injury; 2) worsening neurological symptoms, from mild to moderate or severe, due to injury during the subacute stage; 3) a mix of solid clots (high-density lighter shadow) and fluid hematoma (low-density darker shadow) on the computed tomography (CT) scan; 4) a score of ≥9 on the Glasgow Coma Scale (GCS) assessed immediately before surgery; and 5) an age of ≥65 years. When the majority of the hematoma was evacuated on the CT, we removed the catheter. RESULTS Under local anesthesia, a catheter was inserted into the hematoma through a burr hole. The mean age of the patients was 73.7 years (range, 65-87 years). The mean preoperative GCS score was 11.2 (range, 10-13), and the mean Glasgow Outcome Scale score for all patients was 5 at discharge. No recurrences of hematomas or surgical complications were observed. CONCLUSION A subdural drain using urokinase after burr hole hematoma evacuation under local anesthesia is thought to be an effective and safe method of blood clot removal with low morbidity. This surgical method is less invasive for treating elderly patients with SASDH.

Abstract
Traumatic brain injury (TBI) is one of the main causes of mortality and severe disability in young and middle age patients. Patients with severe TBI, who are in coma, are of particular concern. Adequate diagnosis of primary brain injuries and timely prevention and treatment of secondary injury mechanisms markedly affect the possibility of reducing mortality and severe disability. The present guidelines are based on the authors' experience in developing international and national recommendations for the diagnosis and treatment of mild TBI, penetrating gunshot wounds of the skull and brain, severe TBI, and severe consequences of brain injury, including a vegetative state. In addition, we used the materials of international and national guidelines for the diagnosis, intensive care, and surgical treatment of severe TBI, which were published in recent years. The proposed recommendations for surgical treatment of severe TBI in adults are addressed primarily to neurosurgeons, neurologists, neuroradiologists, anesthesiologists, and intensivists who are routinely involved in treating these patients.

Abstract
Background Mild traumatic brain injury (TBI) patients with initial traumatic intracranial hemorrhage (tICH) and without immediate neuro-surgical intervention require close monitoring of their neurologic status. Progressive hemorrhage and neurologic deterioration may need delayed neuro-surgical intervention. This study aimed to determine the potential risk factors of delayed neuro-surgical intervention in mild TBI patients with tICH on admission. Methods Three hundred and forty patients with mild TBI and tICH who did not need immediate neuro-surgical intervention on admission were evaluated retrospectively. Their demographic information, clinical evaluation, laboratory data, and brain CT was reviewed. Delayed neuro-surgical intervention was defined as failure of non-operative management after initial evaluation. Risk factors of delayed neuro-surgical intervention on admission were analyzed. Results Delayed neuro-surgical intervention in mild TBI with tICH on initial brain CT accounted for 3.8 % (13/340) of all episodes. Higher WBC concentration, higher initial ISS, epidural hemorrhage (EDH), higher volume of EDH, midline shift, and skull fracture were risk factors of delayed neuro-surgical intervention. The volume of EDH and skull fracture is independent risk factors. One cubic centimeter (cm3) increase in EDH on initial brain CT increased the risk of delayed neurosurgical intervention by 16 % (p = 0.011; OR: 1.190, 95 % CI:1.041–1.362). Conclusions Mild TBI patients with larger volume of EDH have higher risk of delayed neuro-surgical interventions after neurosurgeon assessment. Longer and closer neurological function monitor and repeated brain image is required for those patients had initial larger EDH. A large-scale, multi-centric trial with a bigger study population should be performed to validate the findings.

Abstract
OBJECTIVES The aim of this study was to assess the change in trends in the management of traumatic brain injury (TBI) at a level I trauma center and the utilization of resources as a result of this change in management. BACKGROUND The management of TBI has been evolving with trends toward management of minimally injured patients with intracranial hemorrhage exclusively by trauma surgeons. METHODS A 5-year (2009-2014) prospective database on all patients with TBI (skull fracture/intracranial hemorrhage on head computed tomography) presenting to a level I trauma center was analyzed for patient demographics, injuries, admission physiology, computed tomographic scan results, and hospital outcomes. These records were matched to the institutional registry and hospital financial database. RESULTS A total of 2184 patients were included with median (interquartile range) Glasgow Coma Scale score of 15 (12-15), and median (interquartile range) head-abbreviated injury scale score of 3 (2-4). The distribution of types and size of intracranial bleeds remained unchanged throughout the study period. The proportion of TBI managed exclusively by trauma surgeons increased significantly over the years from 6.8% to 40.1% (P < 0.001). Proportion of patients who received neurosurgical consultations (P < 0.001) and repeat head computed tomographic scans (P < 0.001), hospital length of stay (P = 0.028), and costs (P < 0.001) decreased significantly over time. The overall mortality rate (18.5%) and rate of intervention (14.1%) remained unchanged. CONCLUSIONS TBI patients can be selectively managed without initially involving neurosurgeons safely in a cost-effective manner, resulting in more effective use of precious resources.

Abstract
OBJECTIVE The object of this study was to determine the mortality and neurological outcome of patients with mild traumatic brain injury (mTBI) who require neurosurgical intervention (NSI), identify clinical predictors of a poor outcome, and investigate the effect of failed nonoperative management and delayed NSI on outcome. METHODS A cross-sectional study of 10 years was performed, capturing all adults with mTBI and NSI. Primary outcome variables were mortality and Glasgow Outcome Scale (GOS) score. Patients were divided into an immediate intervention group, which received an NSI after the initial cranial CT scan, and a delayed intervention group, which had failed nonoperative management and received an NSI after 2 or more cranial CT scans. RESULTS The mortality rate in mTBI patients requiring NSI was 13%, and the mean GOS score was 3.6 ± 1.2. An age > 60 years was independently predictive of a worse outcome, and epidural hematoma was independently predictive of a good outcome. Logistic regression analysis using independent variables was calculated to create a model for predicting poor neurological outcomes in patients with mTBI undergoing NSI and had 74.1% accuracy. Patients in the delayed intervention group had worse mortality (25% vs 9%) and worse mean GOS scores (2.9 ± 1.3 vs 3.7 ± 1.2) than those in the immediate intervention group. CONCLUSIONS Data in this study demonstrate that patients with mTBI requiring NSI have higher mortality rates and worse neurological outcomes and should therefore be classified separately from mTBI patients not requiring NSI. Additionally, mTBI patients requiring NSI after the failure of nonoperative management have worse outcomes than those receiving immediate intervention and should be considered separately.

Abstract
Limited data exist regarding the use of hemostatic adjuncts on the progression of traumatic intracranial hemorrhage (tICH). The objective of this study was to examine the impact of platelet transfusion and desmopressin (DDAVP) administration on hemorrhage progression following tICH. We hypothesized that platelet and DDAVP administration would not result in decreased early hemorrhagic progression. We performed a three-year retrospective analysis of a Level 1 trauma center database to identify all adult patents with blunt tICH. The primary outcome was early (≤4 hours) radiographic hemorrhagic progression. Secondary outcomes included mortality, frequency of operative interventions, and complications. Multiple logistic regression analysis was performed to identify predictors for hemorrhage progression and mortality. A propensity score analysis also was performed to minimize differences and improve comparability between patients who received platelets and DDAVP and those who did not. Of 408 patients with tICH meeting the inclusion criteria, 126 received platelets and DDAVP (P/D [+]) and 282 did not (P/D [-]). Overall, 37% of patients demonstrated early radiographic hemorrhage progression. On univariate analysis, there was no difference in the incidence of hemorrhage progression between groups (43.7% [P/D (+)] vs. 34.2% [P/D (-)]; p = 0.07). On multivariate analyses, platelet and DDAVP administration was not associated with either a decreased risk of hemorrhage progression (odds ratio [OR] = 1.40, confidence interval [CI] = 0.80-2.40; p = 0.2) or mortality (OR = 1.50, CI = 0.60-4.30; p = 0.4). The administration of platelets and DDAVP is not associated with a decreased risk for early radiographic hemorrhage progression in patients with tICH. Further prospective study of these potentially hemostatic adjuncts in patients with tICH is potentially warranted.

Abstract
BACKGROUND As the population ages, an increasing number of trauma patients are taking antiplatelet and anticoagulant medications (ACAP) prior to their injuries. These medications increase their risk of hemorrhagic complications, particularly intracerebral hemorrhage. Clopidogrel and warfarin are common and their mechanisms well understood, but optimal reversal methods continue to evolve. The novel direct thrombin and factor Xa inhibitors are less well described and do not have existing antidotes. METHODS This article reviews the relevant literature on traumatic outcomes with use of ACAP medications, as well as data on ideal reversal strategies. Suggested algorithms are introduced, and future research directions discussed. RESULTS Although they are beneficial in preventing clot formation, once bleeding occurs ACAP medications contribute to increased morbidity and mortality, particularly in geriatric patient populations. The efficacy of clopidogrel reversal with platelet transfusions and DDAVP remains unclear. Warfarin use is best treated with the algorithm-driven use of plasma, vitamin K, prothrombin complex concentrates (PCCs) and possibly recombinant factor VIIa depending upon specific patient and injury factors. Optimal treatment for direct thrombin and factor Xa inhibitors has yet to be developed, but PCCs are promising for rivaroxaban and apixaban while dabigatran is best treated with medication cessation and the possible addition of activated PCCs or hemodialysis. CONCLUSION New developments in reversal of the ACAP medications are promising, particularly PCCs for warfarin and the factor Xa inhibitors. Function assays and clear antidotes are needed for the thrombin and Xa inhibitors. Research on outcomes and appropriate treatments is actively ongoing.

Abstract
Objective The intracranial pathologies after head trauma should be usually progressed. It is clearly visualized in the non-invasive brain CT. The invasive monitor such as intracranial pressure (ICP) monitoring may be accompanied with the complications. This study aims whether the patients with severe head injury could be managed with serial CT scans. Methods The medical records of 113 patients with severe head injury in the prospectively enrolled trauma bank were retrospectively analyzed. After the emergency care, all the patients were admitted to the intensive care unit for the aggressive medical managements. Repeat brain CT scans were routinely taken at 6 hours and 48 hours after the trauma. ICP monitoring was restrictively applied for the uncertain intracranial pressure based on the CT. The surgical intervention and the mortality rate were analyzed. Results Immediate surgical intervention after the initial CT scan was done in 47 patients. Among the initially non-surgical patients, 59 patients were managed with the serial CT scans and 7 with the ICP monitoring. Surgical interventions underwent eventually for 10 patients in the initially non-surgical patients; 1 in the ICP monitoring and 9 in the serial CT. The mortality rate was 23.7% in the serial brain CT and 28.6% in the ICP monitoring. There was no statistical difference between two groups in the aspect of mortality (p=0.33). Conclusion Serial CT scans in time could be a good way to monitor the intracranial progression in the severe head injury and reduce the implantation of an invasive ICP probe.

Abstract
Background Severe traumatic brain injury (TBI) is a significant health concern and a major burden for society. The period between trauma event and hospital admission in an emergency department (ED) could be a determinant for secondary brain injury and early survival. The aim was to investigate the relationship between prehospital factors associated with secondary brain injury (arterial hypotension, hypoxemia, hypothermia) and the outcomes of mortality and impaired consciousness of survivors at 14 days. Methods A multicenter, prospective cohort study was performed in dedicated trauma centres of Switzerland. Adults with severe TBI (Abbreviated Injury Scale score of head region (HAIS) >3) were included. Main outcome measures were death and impaired consciousness (Glasgow Coma Scale (GCS) ≤13) at 14 days. The associations between risk factors and outcome were assessed with univariate and multivariate regression models. Results 589 patients were included, median age was 55 years (IQR 33, 70). The median GCS in ED was 4 (IQR 3-14), with abnormal pupil reaction in 167 patients (29.2%). Median ISS was 25 (IQR 21, 34). Three hundred seven patients sustained their TBI from falls (52.1%) and 190 from a road traffic accidents (32.3%). Median time from Out-of-hospital Emergency Medical Service (OHEMS) departure on scene to arrival in ED was 50 minutes (IQR 37-72); 451 patients had a direct admission (76.6%). Prehospital hypotension was observed in 24 (4.1%) patients, hypoxemia in 73 (12.6%) patients and hypothermia in 146 (24.8%). Prehospital hypotension and hypothermia (apart of age and trauma severity) was associated with mortality. Prehospital hypoxemia (apart of trauma severity) was associated with impaired consciousness; indirect admission was a protective factor. Conclusion Mortality and impaired consciousness at 14 days do not have the same prehospital risk factors; prehospital hypotension and hypothermia is associated with mortality, and prehospital hypoxemia with impaired consciousness.

Abstract
This adult cohort determined the incidence and patients' short-term outcomes of severe traumatic brain injury (sTBI) in Switzerland and age-related differences. A prospective cohort study with a follow-up at 14 days was performed. Patients ≥16 years of age sustaining sTBI and admitted to 1 of 11 trauma centers were included. sTBI was defined by an Abbreviated Injury Scale of the head (HAIS) score >3. The centers participated from 6 months to 3 years. The results are presented as percentages, medians, and interquartile ranges (IQRs). Subgroup analyses were performed for patients ≤65 years (younger) and >65 (elderly). sTBI was observed in 921 patients (median age, 55 years; IQR, 33-71); 683 (74.2%) were male. Females were older (median age, 67 years; IQR, 42-80) than males (52; IQR, 31-67; p<0.00001). The estimated incidence was 10.58 per 100,000 inhabitants per year. Blunt trauma was observed in 879 patients (95.4%) and multiple trauma in 283 (30.7%). Median Glasgow Coma Score (GCS) on the scene was 9 (IQR 4-14; 8 in younger, 12 in elderly) and in emergency departments 5 (IQR, 3-14; 3 in younger, 8 in elderly). Trauma mechanisms included the following: 484 patients with falls (52.6%; younger, 242 patients [50.0%]; elderly, 242 [50.0%]), 291 with road traffic accidents (31.6%; younger, 237 patients [81.4%]; elderly, 54 [18.6%]), and 146 with others (15.8%). Mortality was 30.2% (24.5% in younger, 40.9% in elderly). Median GCS at 14 days was 15 (IQR, 14-15) without differences among subgroups. Estimated incidence of sTBI in Switzerland was low, age was high, and mortality considerable. The elderly had higher initial GCS and a higher death rate, but high GCS at 14 days.

Abstract
There is currently no accepted standard for deep venous thrombosis (DVT) and pulmonary embolism (PE) prophylaxis in patients with traumatic brain injury (TBI). The objective of our study was to evaluate the effects of implementing a subcutaneous heparin prophylaxis protocol for patients with TBI that began in our hospital as of June 2009. In our retrospective cohort study, we examined 3812 TBI records between January 2007 and December 2011. A significant reduction in the risk of DVT/PE development was not demonstrated by comparing DVT and PE incidences before and after protocol implementation. A clear trend between heparin use and DVT occurrence could not be determined from a review of TBI records after June 2009. The use of heparin after initiation of our protocol among operative TBI cases without intracranial hemorrhage (ICH) based on admission head computed tomography was 58 per cent. ICH complication from heparin prophylaxis was 10.6 per cent for patients with TBI with ICH on admission (five of 47 cases) compared with 0.7 per cent for those without ICH on admission (four of 535 cases).

Abstract
Objective The objectives of the present study were to characterize the natural course of initially non-operated traumatic acute subdural hematoma (ASDH) and to identify the risk factors of hematoma progression. Methods Retrospective analysis was performed using sequential computed tomography (CT) images maintained in a prospective observational database containing 177 ASDH cases treated from 2005 to 2011. Patients were allocated to four groups as followings; 136 (76.8%) patients to the spontaneous resolution group, 12 (6.8%) who underwent operation between 4 hours and 7 days to the rapid worsening group (RWG), 24 (13.6%) who experienced an increase of hematoma and that underwent operation between 7 and 28 days to the subacute worsening group (SWG), and 5 (2.8%) who developed delayed aggravation requiring surgery from one month after onset to the delayed worsening group (DWG). Groups were compared with respect to various factors. Results No significant intergroup difference was found with respect to age, mechanism of injury, or initial Glasgow Coma Scale. The presence of combined cerebral contusion or subarachnoid hemorrhage was found to be a significant prognostic factor. Regarding CT findings, mixed density was common in the RWG and the SWG. Midline shifting, hematoma thickness, and numbers of CT slices containing hematoma were significant prognostic factors of the RWG and the SWG. Brain atrophy was more severe in the SWG and the DWG. Conclusion A large proportion of initially non-operated ASDHs worsen in the acute or subacute phase. Patients with risk factors should be monitored carefully for progression by repeat CT imaging.

Abstract
The magnitude of damage to cerebral tissues following head trauma is determined by the primary injury, caused by the kinetic energy delivered at the time of impact, plus numerous secondary injury responses that almost inevitably worsen the primary injury. When head trauma results in a cerebral contusion, the hemorrhagic lesion often progresses during the first several hours after impact, either expanding or developing new, non-contiguous hemorrhagic lesions, a phenomenon termed hemorrhagic progression of a contusion (HPC). Because a hemorrhagic contusion marks tissues with essentially total unrecoverable loss of function, and because blood is one of the most toxic substances to which the brain can be exposed, HPC is one of the most severe types of secondary injury encountered following traumatic brain injury (TBI). Historically, HPC has been attributed to continued bleeding of microvessels fractured at the time of primary injury. This concept has given rise to the notion that continued bleeding might be due to overt or latent coagulopathy, prompting attempts to normalize coagulation with agents such as recombinant factor VIIa. Recently, a novel mechanism was postulated to account for HPC that involves delayed, progressive microvascular failure initiated by the impact. Here we review the topic of HPC, we examine data relevant to the concept of a coagulopathy, and we detail emerging data elucidating the mechanism of progressive microvascular failure that predisposes to HPC after head trauma.

Abstract
BACKGROUND Patients with traumatic brain injuries (TBIs) are at high risk for venous thromboembolic sequelae; however, prophylaxis is often delayed because of the perceived risk of intracranial hemorrhagic exacerbation. The goal of this study was to determine whether enoxaparin for early venous thromboembolism (VTE) prophylaxis is safe for hemodynamically stable patients with TBIs. METHODS This is a retrospective cohort study from a Level I Trauma Center of patients with TBIs receiving early (0-72 hours) or late (>72 hours) VTE prophylaxis. Inclusion criteria included evidence of acute intracranial hemorrhagic injury (IHI) on admission computed tomography, head/neck abbreviated injury score≥3, age≥16 years, and hospital length of stay≥72 hours. Exclusion criteria included intracranial pressure monitor/ventriculostomy, current systemic anticoagulation, pregnancy, coagulopathy, history of DVT, ongoing intra-abdominal hemorrhage 24 hours postadmission, and preexisting inferior vena cava filter. Progression of IHI defined as lesion expansion/new IHI on repeat computed tomography. RESULTS Totally, 669 patients were identified: 268 early (40.1%) and 401 late (59.9%), with a mean injury severity score of 27.8±10.2 and 29.4±11, respectively. Head neck abbreviated injury score of 3 (47% vs. 34%), 4 (42% vs. 46%), 5 (11% vs. 19%), and 6 (0% vs. 1%) were reported for the early and late treatment groups, respectively. Mean time to prophylaxis was 2.77 days±0.49 days and 5.31 days±1.97 days. IHI progression before prophylaxis was 9.38% versus 17.41% (p<0.001) and after prophylaxis was 1.46% versus 1.54% (p>0.9). Proportions of proximal DVT were 1.5% versus 3.5% (p=0.117) and pulmonary embolism were 1.5% versus 2.2% (p=0.49). There were no differences in injury severity score, age, and pelvic and/or long bone fractures. CONCLUSIONS We found no evidence that early VTE prophylaxis increases the rate of IHI progression in hemodynamically stable patients with TBIs. The natural rate of IHI progression observed is comparable with previous studies. Although not powered to detect differences in the incidence of DVT and pulmonary embolism, the data trend toward increased proportions of both VTE outcomes in the late group.

Prophylactic anticoagulation to prevent venous thromboembolism in traumatic intracranial hemorrhage: a decision analysis. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2010; 14:R72.

Abstract
Introduction Patients with intracranial hemorrhage due to traumatic brain injury are at high risk of developing venous thromboembolism including deep vein thrombosis (DVT) and pulmonary embolism (PE). Thus, there is a trade-off between the risks of progression of intracranial hemorrhage (ICH) versus reduction of DVT/PE with the use of prophylactic anticoagulation. Using decision analysis modeling techniques, we developed a model for examining this trade-off for trauma patients with documented ICH. Methods The decision node involved the choice to administer or to withhold low molecular weight heparin (LMWH) anticoagulation prophylaxis at 24 hours. Advantages of withholding therapy were decreased risk of ICH progression (death, disabling neurologic deficit, non-disabling neurologic deficit), and decreased risk of systemic bleeding complications (death, massive bleed). The associated disadvantage was greater risk of developing DVT/PE or death. Probabilities for each outcome were derived from natural history studies and randomized controlled trials when available. Utilities were obtained from accepted databases and previous studies. Results The expected value associated with withholding anticoagulation prophylaxis was similar (0.90) to that associated with the LMWH strategy (0.89). Only two threshold values were encountered in one-way sensitivity analyses. If the effectiveness of LMWH at preventing DVT exceeded 80% (range from literature 33% to 82%) our model favoured this therapy. Similarly, our model favoured use of LMWH if this therapy increased the risk of ICH progression by no more than 5% above the baseline risk. Conclusions Our model showed no clear advantage to providing or withholding anticoagulant prophylaxis for DVT/PE prevention at 24 hours after traumatic brain injury associated with ICH. Therefore randomized controlled trials are justifiable and needed to guide clinicians.

Abstract
The standard surgical treatment of hemorrhagic cerebral contusion is craniotomy with evacuation of the focal lesion. We assessed the safety and feasibility of performing decompressive craniectomy and duraplasty as the primary surgical intervention in this group of patients. Fifty-four consecutive patients with Glasgow Coma Scale (GCS) scores of less than or equal to 8, a frontal or temporal hemorrhagic contusion greater than 20 cm(3) in volume, and a midline shift of at least 5 mm or cisternal compression on computer tomography (CT) scan were studied. Sixteen (29.7%) underwent traditional craniotomy with hematoma evacuation, and 38 (70.4%) underwent craniectomy as the primary surgical treatment. Mortality, reoperation rate, Glasgow Outcome Scale-Extended (GOSE) scores, and length of stay in both the acute care and rehabilitation phase were compared between these two groups. Mortality (13.2% vs. 25.0%) and reoperation rate (7.9% vs. 37.5%) were lower in the craniectomy group, whereas the length of stay in both the acute care setting and the rehabilitation phase were similar between these two groups. The craniectomy group also had better GOSE score (5.55 vs. 3.56) at 6 months. Decompressive craniectomy is safe and effective as the primary surgical intervention for treatment of hemorrhagic contusion. This study also suggests that patient with hemorrhagic contusion can possibly have better outcome after craniectomy than other subgroup of patients with severe traumatic brain injury.

Abstract
There are few data in the literature on venous thromboembolic (VTE) prophylaxis for the traumatic population with intracranial hemorrhage (ICH). We reviewed our institutional experience and compared the incidence of deep vein thrombosis and pulmonary embolism in patients with ICH receiving either early prophylaxis (<72 hours from admission) or late prophylaxis (>72 hours from admission), and the respective incidences in progression of intracranial hemorrhage. We identified 124 patients for this study. There were 29 patients (23%) who received early (<72 hours) pharmacological VTE prophylaxis and 53 patients (43%) received late (>72 hours) prophylaxis. In the study, 42 patients had intermittent pneumatic compression devices and received no pharmacological VTE prophylaxis. Among those with pharmacological VTE prophylaxis, 10 patients (8%) developed VTE (9 deep vein thrombosis and 1 pulmonary embolism). Three patients with pharmacological VTE prophylaxis developed ICH progression, with one being clinically significant. Our institutional review demonstrated that it seems safe to initiate early pharmacological VTE prophylaxis in blunt head trauma with stable ICH. Nevertheless, further prospective randomized studies are needed to fully elucidate the safety and efficacy in the timing of prophylaxis for blunt head trauma with ICH.

Coagulation disorders after traumatic brain injury. Acta Neurochir (Wien) 2008; 150:165-75; discussion 175. [PMID: 18166989 DOI: 10.1007/s00701-007-1475-8] [Citation(s) in RCA: 229] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2007] [Accepted: 10/01/2007] [Indexed: 10/22/2022]
Abstract
BACKGROUND Over the past decade new insights in our understanding of coagulation have identified the prominent role of tissue factor. The brain is rich in tissue factor, and injury to the brain may initiate disturbances in local and systemic coagulation. We aimed to review the current knowledge on the pathophysiology, incidence, nature, prognosis and treatment of coagulation disorders following traumatic brain injury (TBI). METHODS We performed a MEDLINE search from 1966 to April 2007 with various MESH headings, focusing on head trauma and coagulopathy. We identified 441 eligible English language studies. These were reviewed for relevance by two independent investigators. A meta-analysis was performed to calculate the frequencies of coagulopathy after TBI and to determine the association of coagulopathy and outcome, expressed as odds ratios. RESULTS Eighty-two studies were relevant for the purpose of this review. Meta-analysis of 34 studies reporting the frequencies of coagulopathy after TBI, showed an overall prevalence of 32.7%. The presence of coagulopathy after TBI was related both to mortality (OR 9.0; 95%CI: 7.3-11.6) and unfavourable outcome (OR 36.3; 95%CI: 18.7-70.5). CONCLUSIONS We conclude that coagulopathy following traumatic brain injury is an important independent risk factor related to prognosis. Routine determination of the coagulation status should therefore be performed in all patients with traumatic brain injury. These data may have important implications in patient management. Well-performed prospective clinical trials should be undertaken as a priority to determine the beneficial effects of early treatment of coagulopathy.

Abstract
BACKGROUND Management of a patient with a closed head injury is based on neurologic status and computerized tomography scan results. We hypothesized that those patients with an epidural hematoma (EDH) or subdural hematoma (SDH) <1 cm in thickness could safely be treated nonoperatively. METHODS We retrospectively reviewed charts of 204 consecutive patients with either an EDH or SDH. RESULTS There were 122 lesions < or =1 cm and 82 lesions >1 cm. In the first group, 115 were managed nonoperatively, with 111 good outcomes (minimal deficit with a Rancho Los Amigos score [RLAS] > or =3), two poor outcomes (severely disabled with RLAS <3), and two deaths. Twenty-eight patients with lesions greater than 1 cm had concomitant cerebral edema (CE) with an 89% mortality rate. The mortality rate in this group without CE was 20%, demonstrating the presence of CE in this group may have adversely affected the mortality rate, regardless of intervention. CONCLUSIONS This data suggests that EDH or SDH <1 cm thick can be safely managed nonoperatively unless there is concomitant CE.

Abstract
Traumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide. The modern management of severe TBI has fallen into the domain of a multidisciplinary team led by neurointensivists, neuroanaesthetists, and neurosurgeons and is based on the avoidance of secondary injury, maintenance of cerebral perfusion pressure (CPP), and optimization of cerebral oxygenation. In this review, we will discuss the intensive care management of severe TBI with emphasis on the specific measures directed at the control of intracranial pressure and CPP.

Effects of Recombinant Activated Factor VII in Traumatic Nonsurgical Intracranial Hemorrhage. ACTA ACUST UNITED AC 2006; 63:310-7. [PMID: 16971200 DOI: 10.1016/j.cursur.2006.04.013] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2006] [Revised: 04/20/2006] [Accepted: 04/21/2006] [Indexed: 11/15/2022]
Abstract
OBJECTIVE To determine whether treatment with recombinant activated factor VII (rFVIIa) will prevent progression of bleeding in nonsurgical hemorrhagic traumatic brain injury (TBI). METHODS Chart review from the trauma registry of a level 1 trauma center between January 1, 2002 and December 31, 2004 identified 2 patients who received rFVIIa for progressive hemorrhagic TBI. These patients were given a single dose of rFVIIa (120 mcg/kg) after a repeat head computed tomography (CT) scan showed worsening of intracranial bleeding. Pre-rFVIIa and post-rFVIIa coagulation parameters and postintervention CT scans were performed. A matched convenience sample was drawn from the institution's trauma registry reflecting similar injury patterns. RESULTS The 2 patients who received rFVIIa were ages 61 and 79 years; the patients in the matched convenience sample were 57 and 63 years. Both sets of patients comprised 1 man and 1 woman who had suffered blunt trauma, including hemorrhagic TBI, and were matched according to age, gender, and injury severity score (ISS). During their hospital course, repeat CT scans documented worsening of intracranial hemorrhage in both cohorts. In the rFVIIa patients, follow-up CT showed overall improvement of head injury compared with the convenience sample. The rFVIIa patients also saw an appreciable decrease in both prothrombin time (PT) and international normalized ratio (INR). CONCLUSIONS In hemorrhagic TBI, rFVIIa has the potential to limit or even halt the progression of bleeding that would otherwise place growing pressure on the brain. A prospective, randomized multicenter trial is planned to elucidate this hypothesis.

Abstract
OBJECTIVE To characterize the natural course of traumatic intraparenchymal contusions and hematomas (IPHs) and to identify risk factors for IPH progression in the acute post-injury period. METHODS A retrospective analysis was performed on a prospective observational database containing 113 head trauma patients exhibiting 229 initially nonoperated acute IPHs. The main outcome variable was radiographic evidence of IPH progression on serially obtained head computed tomographic (CT) scans. Secondary outcomes included the actual amount of IPH growth and later surgical evacuation. Univariate and multivariate analyses (using a generalized estimate equation) were applied to both demographic and initial radiographic features to identify risk factors for IPH progression and surgery. RESULTS Overall, 10 IPHs (4%) shrank, 133 (58%) remained unchanged, and 86 (38%) grew between the first and second head CT scan. IPH progression was independently associated with the presence of subarachnoid hemorrhage (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.12-2.3), presence of a subdural hematoma (OR, 1.94; 95% CI, 1.1-3.43), and initial size (OR, 1.11; 95% CI, 1.02-1.21, for each cm volume). Size of initial IPH proportionately correlated with the amount of subsequent growth (linear regression, P < 0.001). Worsened Glasgow Coma Score between initial and follow-up head CT scan (OR, 8.6; 95% CI, 1.5-50), IPH growth greater than 5 cm (OR, 7.3; 95% CI, 1.6-34), and effacement of basal cisterns on initial CT scan (OR, 9.0; 95% CI, 1.5-52) were strongly associated with late surgical evacuation. CONCLUSION A large proportion of IPHs progress in the acute post-injury period. IPHs associated with subarachnoid hemorrhage, a subdural hematoma, or large initial size should be monitored carefully for progression with repeat head CT imaging. Effacement of cisterns on the initial head CT scan was strongly predictive of failure of nonoperative management, thereby leading to surgical evacuation. These findings should be important factors in the understanding and management of IPH.

Abstract
BACKGROUND Repeat head computed tomography (CT) is standard practice for head-injured patients at many trauma centers. Utilization of CT has increased over time, yet effects on outcome and associated risks are unknown. We systematically reviewed the literature to determine the incidence of progression of injury on repeat CT and resulting treatment changes. METHODS Studies were included from Medline, Embase, and a hand search of citations in reviewed articles. Main outcome measures were progression of injury on repeat CT and resulting intervention. Data were abstracted from 30 eligible studies and discrepancies were settled by consensus. RESULTS Progression of injury on repeat CT was evident in 8 to 67% of patients in the included studies. Neurosurgical intervention resulting subsequent to a repeat CT occurred in 0 to 54% of patients. More severe traumatic brain injury, defined by Glasgow Coma Scale, was associated with a higher proportion of patients with progression of injury on CT and subsequent neurosurgical interventions. Risk factors associated with progression of injury on CT or resulting intervention were inconsistently reported, but coagulopathy and injury severity were most commonly reported. Few studies reported changes in nonsurgical management, in-hospital disposition, or adverse events associated with obtaining repeat CTs. CONCLUSION Indications for repeat head CT after traumatic brain injury are unclear. The wide range of reported injury progression on CT and resulting surgical and medical treatment changes suggest there may be a subset of patients who benefit from repeat CT. Further research should stratify by severity of traumatic brain injury, clearly define inclusion and exclusion criteria, address selection bias, quantify progression of injury on CT, determine factors predictive of injury progression and intervention, and assess risks associated with repeat CT.

Abstract
OBJECTIVE The purpose of this review is to review how pediatric trauma may predispose children to sepsis. DESIGN The information discussed in this report is derived from a recent literature review of pediatric trauma and related topics and discussion at an international consensus conference on pediatric sepsis. MEASUREMENTS AND MAIN RESULTS There is a paucity of evidence on sepsis-related complications in pediatric trauma patients. Severe traumatic brain injury is a leading predisposing factor for sepsis complications. Excluding burn trauma, traumatically injured children without severe head injury rarely succumb to overwhelming sepsis. CONCLUSIONS Patients with multiple traumatic injuries are frequently admitted to the intensive care unit, and because head injury is the most common ailment, unconscious patients with a combination of injuries that include head injury will regularly require mechanical ventilation and central venous access and are at risk for life-threatening nosocomial infections. Outside of pulmonary contusions, organ-specific causes of infection are infrequent.

Abstract
BACKGROUND Computed tomography (CT) of the head is the current standard for diagnosing intracranial pathology following blunt head trauma. It is common practice to repeat the head CT to evaluate any progression of injury. Recent retrospective reviews have challenged the need for serial head CT after traumatic brain injury (TBI). This study intends to prospectively examine the value of routine serial head CT after TBI. METHODS Consecutive adult blunt trauma patients with an abnormal head CT admitted to an urban, Level I trauma center from January 2003 to September 2003 were prospectively studied. Variables collected included: initial head CT results, indication for repeat head CT (routine versus neurologic change), number and results of repeat head CT scans, and clinical interventions following repeat head CT. RESULTS Over the 9-month period, there were 128 patients admitted with an abnormal head CT after sustaining blunt trauma. The 16 patients who died within 24 hours and the 12 patients who went directly to craniotomy were excluded. The remaining 100 patients make up the study population. Abnormal head CT findings were subarachnoid hemorrhage (47%), intraparenchymal hemorrhage (37%), subdural hematoma (28%), contusion (14%), epidural hematoma (11%), intraventricular hemorrhage (3%), and diffuse axonal injury (2%). Overall, 32 patients (32%) had only the admission head CT, while 68 patients (68%) underwent 90 repeat CT scans. Of the repeat head CT scans, 81 (90%) were performed on a routine basis without neurologic change. The remaining 9 (10%) were performed for a change in Glasgow Coma Scale (n = 5), change in intracranial pressure (n = 1), change in Glasgow Coma Scale and intracranial pressure (n = 1), change in pupil size (n = 1), or sudden appearance of a headache (n = 1). Three patients had their care altered after repeat head CT: two underwent craniotomy and one was started on barbiturate therapy. All three patients had their repeat head CT after neurologic change (decrease in Glasgow Coma Scale in 2 and increase in intracranial pressure in 1). CONCLUSIONS Serial head CT is common after TBI. Most repeat head CT scans are performed on a routine basis without neurologic change. Few patients with TBI have their management altered after repeat head CT, and these patients have neurologic deterioration before the repeat head CT. The use of routine serial head CT in patients without neurologic deterioration is not supported by the findings of this study.

Abstract
The incidence of deep venous thrombosis (DVT) and subsequent pulmonary embolism (PE) in patients undergoing neurosurgery has been reported to be as high as 25%, with a mortality rate from PE between 9 and 50%. Even with the use of pneumatic compression devices, the incidence of DVT has been reported to be 32% in these patients, making prophylactic heparin therapy desirable. Both unfractionated and low-molecular-weight heparin have been shown to reduce the incidence of DVT consistently by 40 to 50% in neurosurgical patients. The baseline rate for major intracranial hemorrhage (ICH) following craniotomy has been reported to be between 1 and 3.9%, but after initiation of heparin therapy this rate has been found to be as high as 10.9%. Therefore, neurosurgeons must balance the risk of PE against the increased risk of postoperative ICH from prophylactic heparin for DVT. The authors review the literature on the incidence of DVT and PE in neurosurgical patients, focusing on the incidence of ICH related to the use of unfractionated and low-molecular-weight heparin in this patient population
