Suicide after traumatic brain injury: a population study. (1/39)

OBJECTIVES: To determine the rates of suicide among patients who have had a traumatic brain injury. METHODS: From a Danish population register of admissions to hospital covering the years 1979-93 patients were selected who had had either a concussion (n=126 114), a cranial fracture (n=7560), or a cerebral contusion or traumatic intracranial haemorrhage (n=11 766). All cases of deaths by the end of the study period were identified. RESULTS: In the three diagnostic groups there had been 750 (0.59%), 46 (0.61%), and 99 (0.84%) cases of suicide respectively. Standardised mortality ratios, stratified by sex and age, showed that the incidence of suicide among the three diagnostic groups was increased relative to the general population (3.0, 2.7, and 4.1 respectively). In all diagnosis groups the ratios were higher for females than for males, and lower for patients injured before the age of 21 or after the age of 60. The presence of a codiagnosis relating to substance misuse was associated with increased suicide rates in all diagnosis groups. There was a tendency, among patients with cerebral contusions or traumatic intracranial haemorrhages, for suicide risk to increase with duration of stay in hospital. Cox regression analyses for proportional hazards confirmed that there was a significantly greater risk of suicide among patients with cerebral contusions or traumatic intracranial haemorrhages than among patients with concussion or cranial fractures (hazard ratios=1.42 and 1.50 respectively). There was, however, no evidence of a specific risk period for suicide after injury. CONCLUSION: The increased risk of suicide among patients who had a mild traumatic brain injury may result from concomitant risk factors such as psychiatric conditions and psychosocial disadvantage. The greater risk among the more serious cases implicates additionally the physical, psychological, and social consequences of the injuries as directly contributing to the suicides.  (+info)

The structural basis of moderate disability after traumatic brain damage. (2/39)

The objective was to discover the nature of brain damage in survivors of head injury who are left with moderate disability. Macroscopic and microscopic examination was carried out on the brains of 20 persons who had died long after a head injury that had been treated in a neurosurgical unit. All had become independent but had various disabilities (moderate disability on the Glasgow outcome scale) Most deaths had been sudden, which had led to their referral from forensic pathologists. Post-traumatic epilepsy was a feature in 75%. An intracranial haematoma had been evacuated in 75%, and in 11 of the 15 with epilepsy. Diffuse axonal injury was found in six patients, five of the mildest type (grade 1) and one of grade 2. No patient had diffuse thalamic damage but one had a small focal ischaemic lesion in the thalamus. No patient had severe ischaemic brain damage, but three had moderate lesions which were bilateral in only one. No patient had severe cortical contusions. In conclusion, the dominant lesion was focal damage from an evacuated intracranial haematoma. Severe diffuse damage was not found, with diffuse axonal injury only mild and thalamic damage in only one patient.  (+info)

Giant cell glioblastoma manifesting as traumatic intracerebral hemorrhage--case report. (3/39)

A 33-year-old male presented with intracerebral hemorrhage in the left temporoparietal region after a traffic accident. Ten months later, the traumatic hemorrhage was found to originate in an underlying giant cell glioblastoma. Our case indicates that non-traumatic underlying pathologies, such as vasculopathies, coagulopathies, or tumors, should be considered in the differential diagnoses of intracerebral hemorrhage occurring in unusual locations after traumatic accidents.  (+info)

Magnetization transfer MR imaging in patients with posttraumatic epilepsy. (4/39)

BACKGROUND AND PURPOSE: Intractable epilepsy is a well-recognized complication following head trauma, and many factors have been implicated in its pathogenesis. This study was performed to determine the severity of tissue damage after severe head injury as assessed with magnetization transfer (MT) MR imaging and the relationship of this damage with seizure intractability. METHODS: Forty-four patients, 13 without seizures (disease controls) and 31 with seizures, underwent T1-weighted MT MR imaging 1-10 years after head trauma. Phase-corrected gradient-echo (GRE) imaging was also performed in all patients to look for the presence of hemosiderin. All patients were evaluated for the presence of an MT abnormality beyond an abnormality seen on T2-weighted images, an MT abnormality within a T2 abnormality, and hemosiderin deposition. RESULTS: Patients with an MT abnormality beyond a T2 abnormality had a significantly higher intractability of seizures compared with those with an MT abnormality within a T2 abnormality (P <.05). In addition, the mere presence of hemosiderin deposit was not associated with seizure intractability; however, gliosis around the hemosiderin as seen on T1-weighted MT images was associated with seizure intractability. CONCLUSIONS: T1-weighted MT imaging may be of value in predicting the intractability of the seizure in delayed posttraumatic epilepsy.  (+info)

Acute fatal haemorrhage during percutaneous dilatational tracheostomy. (5/39)

Percutaneous dilatational tracheostomy (PDT) is associated with a number of life-threatening complications. We present a case of massive and fatal arterial haemorrhage that occurred in the intensive care unit during an elective PDT on an 86-year-old woman following earlier evacuation of a traumatic subdural haematoma. An avulsed right subclavian artery was found at post mortem. Previous thyroid surgery and aberrant arterial anatomy contributed to the fatal outcome.  (+info)

Low doses of dexamethasone decrease brain water content of collagenase-induced cerebral hematoma. (6/39)

Different doses of dexamethasone were evaluated for the treatment of cerebral trauma using a rat model of cerebral hematoma induced by intracerebral (IC) stereotaxic injections of collagenase. Control animals received an intracerebral collagenase injection followed by intraperitoneal (IP) saline injection. Sham operated animals received saline only (IC, IP). Forty-eight hours following the surgeries, the brains were removed from the euthanized animals. Cerebral hemispheres were separated and the 4 coronal sections (antero-posterior plane) were weighed. Each slice was dried for 24 h (100 degrees C) and weighed again to establish brain water content. In hematoma-induced saline treated rats, significant differences in brain water content were observed when compared to sham operated animals. Rats treated with 1 mg/kg dexamethasone had a significant brain water content decrease; however, no significant differences were observed with higher doses of dexamethasone. In conclusion, low doses of dexamethasone seem to be beneficial for the treatment of cerebral trauma.  (+info)

Diffuse axonal injury associated with chronic traumatic brain injury: evidence from T2*-weighted gradient-echo imaging at 3 T. (7/39)

BACKGROUND AND PURPOSE: Diffuse axonal injury is frequently accompanied by tissue tear hemorrhages. We examined whether high field strength T2*-weighted gradient-echo imaging performed during the chronic stage of traumatic brain injury may have advantages in the evaluation of diffuse axonal injury as compared with T1- and T2-weighted MR imaging. METHODS: Prospective MR imaging of 66 patients (age range, 17-57 years) was performed using a 3-T system 3 to 292 months (median, 23.5 months) after traumatic brain injury. T1-, T2-, T2*-hypointense and T2-hyperintense foci of 1- to 15-mm diameter were registered in 10 brain regions by two readers separately. Foci that appeared hypointense both on the T1- and T2- and/or on the T2*-weighted images were defined as traumatic microbleeds. RESULTS: For 46 (69.7%) of the patients, T2*-weighted gradient-echo imaging revealed traumatic microbleeds. Hyperintense foci were observed on the T2-weighted images of only 15 (22.7%) patients. T2*-weighted imaging showed significantly more traumatic microbleeds (P =.000) than did T1- and T2-weighted imaging. Interobserver agreement was strong (kappa = 0.79, tau = 0.749, P =.000). For 14 (21.2%) of the patients, T2*-weighted gradient-echo imaging revealed traumatic microbleeds in the corpus callosum, whereas for only two (3%), hyperintense callosal lesions were seen on the T2-weighted images. Although a significant correlation existed between the total amount and callosal appearance of traumatic microbleeds and Glasgow Coma Scale scores (P =.000), no correlation existed with extended Glasgow Outcome Scale scores. CONCLUSION: T2*-weighted gradient-echo imaging at high field strength is a useful tool for the evaluation of diffuse axonal injury during the chronic stage of traumatic brain injury. Diffuse axonal injury-related brain lesions are mainly hemorrhagic. The relevance of diffuse axonal injury for long-term clinical outcome is uncertain.  (+info)

Endovascular management of intracranial pial arterio-venous fistulas. (8/39)

From 1996-2002 we treated 5 consecutive cases of pial fistula. There were 3 patients with a single hole-single channel pial fistula and two patients had a complex pial fistula. Three patients presented with intracerebral hematoma and had a focal neurological deficit. One patient presented with history of seizures and 1 patient had headache. The results of the treatment were analyzed both clinically and angiographically. The follow-up period ranged from 6 months to 6 years. All fistulas were treated with concentrated glue. The glue cast included the distal part of the feeding artery, A-V connection and the proximal part of the vein. Post-embolisation angiography showed complete occlusion of two single-hole fistulas and one complex pial A-V fistula and near total occlusion of one single-hole and one complex pial A-V fistula. Four patients had excellent clinical outcome. One patient with single-hole fistula had a hemorrhagic venous infarct resulting in transient hemiparesis.  (+info)

121 Introduction: Serial changes in cerebral blood flow after intracerebral hemorrhage may influence tissue viability in regions surrounding the hematoma. Non invasive monitoring may assist titration of systolic blood pressure. Purpose: To determine if continuous quantitative electroencephalography percent alpha variability(EEGPAV)can discriminate areas of critically reduced cerebral blood flow (CBF). Methods:Ten patients with traumatic intracerebral hemorrhage underwent combined monitoring of cerebral microdialysis, EEGPAV, and intermittent xenon-computerized tomograhpy to determine if EEGPAV monitoring could determine and monitor cellular distress in the context of oligemia. Critical oligemia was defined as CBF , 25. Time and regional matched samples of EEG, microdialysis and CBF were used to correlate across modalities. Regions adjacent to the hematoma only were studied. Results:Six patients had regional CBF , 25 and 4 , 30 cc/100gm/min. In the low CBF group, the mean regional EEGPAV was 0.11 ...

A small number of patients with an apparently minor head injury will develop a life-threatening intracranial hematoma that must be rapidly detected and removed. To assess the risk of a significant intracranial neurosurgical complication after apparently minor head injury, the authors collected data prospectively on 610 patients who had sustained a transient posttraumatic loss of consciousness or other neurological function and who had a Glasgow Coma Scale (GCS) score of 13, 14, or 15 in the emergency room. Skull x-ray films were obtained in 583 patients, 66 of whom (10.8% of the study population) had cranial fractures. Eighteen of the 610 patients (3.0%) required a neurosurgical procedure. Three acute subdural hematomas, one epidural hematoma, and one traumatic intracerebral hematoma required craniotomy. Of the 66 patients who had skull fracture, 7.6% required a craniotomy for intracranial hematoma. Thirteen (19.7%) of the 66 patients with skull fracture required an operative procedure as ...

A 66-year-old male patient, with an unremarkable past medical history, was admitted via the emergency department with blunt trauma. He presented in shock with an open wound of his left thigh and massive bleeding, suggestive of left femoral vessel injury, along with a traumatic intracerebral hemorrhage, a left femoral mid-shaft fracture and left hip dislocation. His initial blood pressure was 50/20mm Hg and pulse rate was 130/minute. Our trauma team decided to perform REBOA using a RESCUE balloonTM catheter (Tokai Medical Products, Aichi, Japan) and 7 Fr. Radiofocus® Introducer II (Terumo, Tokyo, Japan) via his right common femoral artery, targeting zone III. After performing total inflation of the balloon using normal saline, we checked its position using portable X-ray, and found that the catheter was placed at zone II (Fig. 1). We planned to reposition the REBOA catheter to zone III in the emergency room, however, the patients vital signs worsened and we decided to reposition the catheter in ...

TY - JOUR. T1 - Surgery for intracerebral hematoma. T2 - The search for the elusive right candidate. AU - Rabinstein, Alejandro A.. AU - Wijdicks, Eelco F.M.. PY - 2006/9/1. Y1 - 2006/9/1. N2 - The value of surgery for patients with intracerebral hemorrhage (ICH) remains a topic of debate. Although several studies have been unable to prove the benefit of surgical intervention of ICH, there is available evidence to suggest that some patients may experience favorable outcome with surgery. Identifying optimal candidates and the timing of surgery for the treatment of ICH are crucial issues. Studies have explored the value of early and ultra-early surgical intervention, as well as the role of stereotactic hematoma evacuation. The International Surgical Trial in Intracerebral Hemorrhage suggested that favorable surgical outcome was more likely for patients with superficial hematomas, and patients who underwent craniotomy in the trial seemed to fare better than those treated with other surgical ...

Histology in DAI. A number of histological techniques are available to appreciate sequential pathological changes in axons in diffuse axonal injury. These are primarily aimed at shortening the duration at which the axonal changes are seen and to put them in context to various traumatic and non traumatic conditions so as to differentiate the causative mechanism. Axonal swellings or retraction balls, representing transected axons, are the histological hallmark of axonal injury but are usually not visible before 24 to 36 hours by routine H & E staining or with a myelin stain like Luxol fast blue [2]. Silver staining method can reliably demonstrate axonal swellings within 12 to 18 hours [27]. The method has been found to be more sensitive and reliable as compare to H & E staining. However diffuse staining of axons by silver stains may occasionally make differentiation of injured and irregular axons difficult thereby limiting their practical utility [28]. Injuries to the axons may be detected even ...

Cerebral contusion, Latin contusio cerebri, a form of traumatic brain injury, is a bruise of the brain tissue. Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20-30% of severe head injuries. A cerebral laceration is a similar injury except that, according to their respective definitions, the pia-arachnoid membranes are torn over the site of injury in laceration and are not torn in contusion. The injury can cause a decline in mental function in the long term and in the emergency setting may result in brain herniation, a life-threatening condition in which parts of the brain are squeezed past parts of the skull. Thus treatment aims to prevent dangerous rises in intracranial pressure, the pressure within the skull. ...

Seventy cases of intracerebral hematomas were analysed, forty-six of spontaneous origin and remainder of traumatic one, which had been experienced in Seoul National University Hospital between March, 1970 and June, 1975. The results were as follows: A. Among forth-six cases of spontaneous intracerebral hematomas, twenty-six cases(52%) were primary intracerebral hematomas, normotensive or hypertensive, seven aneurismal ruptures(15%), seven arteriovenous malformations(15%), two cerebral rete mirabilies, one tumor bleeding, one leukemia, one idiopathic thrombocytopenic and one due to other blood dyscrasia. 1. Among twenty-six cases of primary intracerebral hematomas, angiography was performed in all and fourteen cases were operated. The sites of hemorrhage were as follows: a. Putaminal hemorrhage:17 cases(65%)(two cases associated with intraventricular hematoma). b. Thalamic hemorrhage:5 cases(19%)(two cases associated with intraventricular hematoma). c. Subcortical hemorrhage:4 cases(16%). 2. ...
Mycotic aneurysms are produced by an infected embolus from vegetations on the heart valves in bacterial endocarditis, which breaks off and lodges in the cerebral blood vessels. The wall of the embolized vessel becomes infected, invasion by inflammatory cells and necrosis of the wall are often followed by rupture and formation of a aneurysmal sac. These aneurysms are very are in incidence and are usually located more peripherally in the vascular tree than berry aneurysms, are more irregular in shape and are not necessarily located at bifurcations. Recently we experienced a case of mycotic aneurysm with intracerebral hematoma which had developed in a subacute bacteria endocarditis patient. The patient was 44 years old male patient with dilated right pupil and left hemiplegia. He was treated surgically by evacuation of intracerebral hematoma and excision of mycotic aneurysm. We also experienced another case of mycotic aneurysm with intracerebral hematoma in 17 years old male patient who had been ...

The management of non-life threatening spontaneous intraparenchymal hemorrhage with no obvious medical etiology in patients and the lack of findings on images has not been clearly defined. In general, the current practice is to treat these patients conservatively and repeat studies to rule out a treatable cause 6 weeks to 3 months later; more often than not these repeated studies fail to reveal any findings, and the patient is treated conservatively. For years, the senior author (R.C.H.) has treated these patients with early surgical exploration. This study was undertaken prospectively to ascertain the frequency of positive findings during surgical exploration. Methods. Between 2000 and 2007, the authors prospectively collected data from 9 cases (4 ...

Diffuse Axonal Injury is a brain injury associated most closely with the rotation and disruption of your brain within the cranium. This can cut away, shear or sever the brain axons, which are connecting nerve fibers. Damage such as this is typically difficult to analyze. It is also accompanied by microscopic tears that are difficult to locate from the get go.. If doctors diagnose your case as a mild brain injury you may notice that thus the wounds heal over time. But often, a DAI results in permanent disabilities from loss of consciousness to lifetime coma. Eventually, a fatality could be the nexus of a future wrongful death claim in civil court and even a murder case in criminal court.. Currently, medical science has not discovered a methodology to treat diffuse axonal injuries. But medical experts have observed in some studies that the damage to axons occurs in the first 12 to 24 hours after the head impact. Many are confident that modern advances in science will be able to treat and/or slow ...

BACKGROUND: Deep brain stimulation (DBS) is a well-established treatment to reduce tremor, notably in Parkinson disease. DBS may also be effective in post-traumatic tremor, one of the most common movement disorders caused by head injury. However, the cohorts of patients often have multiple lesions that may impact the outcome depending on which fiber tracts are affected. CASE DESCRIPTION: A 20-year-old man presented after road traffic accident with severe closed head injury and polytrauma. Computed tomography scan showed left frontal and basal ganglia hemorrhagic contusions and intraventricular hemorrhage. A disabling tremor evolved in step with motor recovery. Despite high-intensity signals in the intended thalamic target, a visual analysis of the preoperative diffusion tensor imaging revealed preservation of connectivity of the intended target, ventralis oralis posterior thalamic nucleus (VOP). This was confirmed by the postoperative tractography study presented here. DBS of the VOP/zona incerta was
Objectives: We sought to describe the frequency and location of headache in intracerebral hematoma (ICH) and to analyze its clinical and CT predictors by means of multivariate analysis. Background: Headache is more common in intracerebral hemorrhage than in ischemic stroke, and its frequency varies with hematoma location, but the pathophysiologic mechanisms of headache associated with ICH are not fully known. Methods: We examined a cohort of 289 patients with ICH during a 14-month period in a university hospital. Clinical, including the presence and location of headache, and CT features were collected by two neurologists. Results: One hundred and sixty-five (57%) patients with ICH had a headache at the onset of their stroke. Headache was more common in cerebellar and lobar hemorrhages than in deep ones (thalamic, caudate, capsuloputaminal, brainstem). Headache was also more common in women, patients younger than 70 years, those who vomited, and those with meningeal signs, a Glasgow Coma Scale ...
Proposal for standardized preanalytical and analytical conditions for measuring thrombin generation in hemophilia. Readouts from the thrombin generation (TG) assay (TGA) have been used to predict the effects of hemostatic drugs in hemophilic patients [1]. There is better correlation between an individuals bleeding tendency and his or her TG capacity compared with factor levels measured using routine assays [2, 3]. However, the clinical utility of TGA has not yet been validated in multicenter studies because of lack of standardization. This report aims to highlight variables that may impact directly on TGA reliability and steps to reduce TGA variability within and between laboratories to improve precision of results.

An emerging field of research focuses on using biomarkers as a different non-invasive clinical approach for diagnosis of DAI. These markers could be detected in CSFsamples due to the breakdown products of neurons and diffusion through the damaged blood brain barrier of traumatic brain injury patients. Possible biomarkers could include proteins associated with primary structural damage or with the cellular and molecular cascade involved in secondary axonomy. Axonal and glial biomarkers include neurofilaments (NF), microtubule-associated protein tau, and α-II Spectrin, and myelin basic protein. These are all critical components of the cytoskeleton or myelin that are dephosphorylated, degraded, depolymerized, and form protein bundles upon injury due to the action of proteolytic enzymes. Biomarkers associated with the molecular cascade during secondary axonomy include β-Amyloid precursor protein, an axoplasmic transport protein that accumulates in the retraction balls, amyloid β, FE65, and ...
Diffuse Axonal Injury (DAI). Trauma professionals tend to focus on the two extremes of TBI: mild concussive injury because we see so much of it, and very severe injury that we have to work so hard to keep the patient alive. Today Ill write about the one in the middle, diffuse axonal injury (DAI). People dont talk about it nearly as much, and it seems kind of mysterious.. DAI is also known as a shear injury, because thats what we think happens to the brain at the time of injury. Officially, it is diagnosed when a patient remains in a coma for more than 6 hours without a demonstrable mass lesion from bleeding seen on CT. It is seen in about 15% of trauma ICU patients with head injury. Essentially the substance of the brain moves around enough to disrupt a critical mass of axonal connections that results in prolonged unconsciousness. It then takes time to try to rebuild those connections and restore consciousness and some degree of cognition. Mechanisms which result in sudden acceleration or ...

Can you die from post concussive syndrome - Can you die from post concussive syndrome? Not likely. Post concussive syndrome should not be fatal. Although this is one of the disorders under traumatic brain injury, concussion should not show abnormalities on ct scan or the diagnosis changes to something more severe such as diffuse axonal injury.

They dont think at this point, that Cale is ever going to be able to care for himself. Theyre hoping that when he starts walking (which could be this week!) that he can get to the point of being aware enough that he can hold a conversation and know whats going on around him. The last 10 weeks its been them saying they dont know, they just dont know. Now, theyve diagnosed Cale with severe diffuse axonal injury. I KNOW God is still in control and works miracles. Im not giving up or loosing hope, Im just realizing that its not just me saying anymore that Cale might be like this forever, its reality. As of today they are still estimating 5 weeks left in this program, but at this point are not thinking hes going to make it to rehab and that I should start making plans for our life this way.
