Fatal Penetrating Head Injuries Caused by Projectile Tear Gas Canisters.

BACKGROUND: Since their advent in the 1920s, tear gas canisters (TGCs) have been frequently used in crowd control. Few reports have documented nonpenetrating injuries attributed directly to TGCs. In this study, we report a case series of fatal penetrating head injuries caused by TGCs. METHODS: We conducted a retrospective chart review of all the patients who were admitted to the Neurosurgery Teaching Hospital in Baghdad, Iraq, since the start of the antigovernment protests (October 2019). All patients who suffered penetrating head trauma caused by TGCs were included in our study. We collected patient demographics, wound location, neurologic examination, computed tomography (CT) scan findings, surgical management, and clinical outcomes. RESULTS: We found 10 cases of penetrating head trauma caused by TGCs. All victims were men, with a mean age of 16 years (range, 14-19 years). The mean Glasgow Coma Scale score was 7 (range, 3-10). The neurologic examination revealed unilateral hemiplegia/hemiparesis and pupillary abnormality in 40% (n = 4) and 50% (n = 5) of the patients, respectively. CT scans revealed an extensive pattern of brain damage. Surgical intervention was done in 80% of cases (n = 8), which included removal of the TGC, wound debridement, and hemostasis. The in-hospital mortality rate was 100% (N = 10), with all fatalities occurring within 1-3 days of admission. CONCLUSIONS: TGCs have the potential to cause lethal penetrating head injuries, calling for a reevaluation of their safety and methods of use in terms of human health.

Survival following Self-Inflicted Gunshots to the Face.

BACKGROUND: Self-inflicted gunshot wounds involving the face are highly morbid. However, there is a paucity of objective estimates of mortality. This study aims to provide prognostic guidance to clinicians that encounter this uncommon injury. METHODS: A retrospective review of patients presenting to R Adams Cowley Shock Trauma Center (a Level I trauma center) with self-inflicted gunshot wounds to the face from 2007 to 2016. Isolated gunshot wounds to the calvaria or neck were excluded. The data were analyzed to determine predictors of survival. RESULTS: Of the 69 patients that met inclusion criteria, 90 percent were male and 80 percent were Caucasian, with an age range of 21 to 85 years. The most frequently seen injury patterns showed submental (57 percent), intraoral (22 percent), and temporal (12 percent) entry sites. Fewer than half (41 percent) of the cohort sustained penetrative brain injury. Overall, there were 18 deaths (overall mortality, 26 percent), 17 of which were secondary to brain injury. Independent predictors of death included penetrative brain injury (OR, 17; p < 0.0001) and age. Mortality was 17 percent among patients younger than 65 years, compared with 73 percent for those aged 65 years or older (p = 0.0001). Gastrostomy placement was independently associated with 25 percent reduction in length of hospitalization (p = 0.0003). CONCLUSIONS: Despite tremendous morbidity, the overwhelming majority of patients who present with facial self-inflicted gunshot wounds will survive, especially if they are young and have no penetrative brain injury. These findings should help guide clinical decisions for this devastating injury. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Outcome and rational management of civilian gunshot injuries to the brain-retrospective analysis of patients treated at the Helsinki University Hospital from 2000 to 2012.

BACKGROUND: Treatment of gunshot wounds of the brain (GSWB) remains controversial and there is high variation in reported survival rates (from < 10 to > 90%) depending on the etiology and country. We retrospectively analyzed the outcome of a series of consecutive GSWB patients admitted alive to a level 1 trauma center in a safe high-income welfare country with a low rate of homicidal gun violence. METHODS: Patients admitted due to a GSWB to the HUS Helsinki University Hospital during 2000-2012 were identified from hospital discharge registry and log books of the emergency room and ICU. CT scans and medical records of these patients were reviewed. Univariate analysis and backward logistic regression were performed, and their results compared with that of a systematic literature review of factors related to the outcome of GSWB patients. RESULTS: Sixty-four patients admitted alive after GSWB were identified. Eighty percent had self-inflicted GSWB, 81% were contact shots, and 70% were caused by handguns. In-hospital mortality was 72%. Factors associated with mortality in our series were low GCS (≤ 8) at admission, transventricular bullet trajectory, and associated damage to deep brain structures, as reported before in the literature. Of the 64 patients admitted alive, 42% (27/64) were admitted to ICU, 34% (22/64) underwent surgery, and in 25% (16/64), craniotomy and hematoma evacuation was performed. Mortality in the surgically treated group was 32% but near 100% without surgery and ICU treatment. Median GOS in the surgically treated patients was 3 (range 1-5). CONCLUSIONS: GSWB caused by contact shot from handguns has a high mortality rate, but can be survived with reasonable outcome if limited to lobar injury without significant damage to deep brain structures or brain stem. In such GSWB patients, initial aggressive resuscitation, ICU admission, and surgery seem indicated.

Outcome of Craniocerebral Penetrating Injuries: Experience from the Syrian War.

OBJECTIVES: Gunshot wounds to the brain are the most fatal of all firearm injuries. The aim of this study was to evaluate mortality and morbidity in patients with penetrating craniocerebral gunshot injuries and to identify risk factors that affect the outcome. PATIENTS AND METHODS: A retrospective review from June 2012 to November 2013 of 44 Syrian patients with gunshot wound to the head was performed. A thorough physical examination and computed tomography (CT) of the brain was obtained for all patients at the time of admission. Associated systemic injuries were found in 19 patients (43%). Surgical intervention was performed in 25 patients (57%); the remaining patients were managed conservatively. The patients were followed for a period of 1 to 15 months (range: 6 ± 2 months). Univariate analysis of patient age, sex, type of penetrating object, Glasgow Coma Scale (GCS) score and pupil size on admission, brain CT findings, presence of systemic injuries, and surgical intervention on the patient outcome was performed. RESULTS: Eleven patients (25%) had a bullet injury; the remaining 33 (75%) patients had blast injuries. Initial brain CT revealed different types of skull fractures, intracerebral hemorrhage, and brain edema in all patients. The mortality rate during the follow-up period was 25%. Of the survivors, 25 patients (76%) had a good recovery, eight patients (24%) had a mild disability, and none had a severe disability. The significant factors determining outcome in this series were GCS on admission (p < 0.005) and positive pupil reaction to light (p < 0.05). The patient age, sex, CT findings, systemic injuries, neurosurgical intervention, and hospital length of stay were not significant prognostic factors (p > 0.05). CONCLUSIONS: Among various variables, GCS and pupil reactivity were the outcome predictors in patients with penetrating craniocerebral injuries. Age, sex, type of penetrating object, CT findings, and surgical intervention did not have a significant effect on survival for these kinds of injuries.

Trends in civilian penetrating brain injury: A review of 26,871 patients.

INTRODUCTION: The aim of our study is to analyze the 5 years' trends, mortality rate, and factors that influence mortality after civilian penetrating traumatic brain injury (pTBI). METHODS: We performed a 5-year-analysis of all trauma patients diagnosed with pTBI in the TQIP. Our outcome measures were trends of pTBI. RESULTS: A total of 26,871 had penetrating brain injury over the 5-year period. Mean age was 36.2 ±â€¯18 years. Overall 55% of the patients had severe TBI and mortality rate was 43.8%. There was an increase in the rate of pTBI from 3042/100,000 (2010) to 7578/100,000 trauma admissions (2014) (p < 0.001). The mortality rate has increased from 35% (2010) to 48% (2011) (p < 0.001) followed by a linear decrease in mortality to 40% (2014). Independent predictors of mortality were age, pre-hospital intubation, suicide attempt, and craniotomy/craniectomy. CONCLUSIONS: Incidence and mortality for patients who are brought to hospitals following pTBI have gradually increased over the five-year period. Self-inflicted injury and prehospital intubation were the two most significant predictors of mortality.

Outcomes and demostration of cranial firearm injuries: A multicenter retrospective study.

BACKGROUND: Cranial firearm injuries (CFAI) are associated with significant morbidity and mortality.This study was aimed to determine the factors affecting mortality of CFAI cases managed in our institution by a retrospective analysis of CT scans and clinical data. METHODS: This multicenter retrospective study examined two hundred and nineteen patients presenting to neurosurgery clinics after CFAI between January 2012 and November 2014. Age, sex, Glasgow Coma Score (GCS), CT findings, and mortality and morbidity rates of the patients were analyzed to determine the factors affecting mortality. RESULTS: Mean age of the study population was 24.19±12.25 years, 85.8% of them were male. The most common CT findings were fracture (100%), intracranial hemorrhage (61.2%), and an intracranially located foreign body (44.3%). A cranial operation was performed in 64.8% of the victims. Mean GCS on admission was 8±3.9, which increased in survivors (p<0.05). CONCLUSION: CFAIs are associated with increased mortality and morbidity. We determined that many factors affected morbidity and mortality rates, and patient age, presence of intracranial hemorrhage, GCS, and treatment protocols were significantly associated with mortality.

[Methodological aspects of surgical approach in victims with severe multiple craniofacial trauma in consideration of severity of traumatic injury].

It is important to improve the medical care system and treatment of victims, introduce new methods of treatment and attract the multidisciplinary specialists in the cases of multitrauma. An integrated approach is required for the identification of different character and severity of multiple craniofacial injuries and the development of rational surgical strategy on this base. Different scales such as AIS, CRIS, ISS, PTS, TRISS, TRISSCAN, CRAMS et.al, were created abroad. Another approach to medical strategy was developed in the department of military surgery of Kirov Military Academy in the late nineties. It was based on investigating of possibilities of surgical strategy optimization by application of objective evaluation of the severity of injuries (military surgery--SP, SG, SS). Given treatment strategy of victims with multiple craniofacial trauma resulted in double reduction of quantity of suppurative and septic complications (from 10.5% to 4.1%). It gave the possibility to reduce the lethality from 6.4% to 4.0%. At the same time a hospital stay was shortened and the strategy allowed obtaining satisfactory functional results of treatment and avoiding reinterventions for removal of posttraumatic facial deformations.

Predictors of outcome in civilian gunshot wounds to the head.

OBJECT: Civilian gunshot wounds to the head (GSWH) are often deadly, but some patients with open cranial wounds need medical and surgical management and are potentially good candidates for acceptable functional recovery. The authors analyzed predictors of favorable clinical outcome (Glasgow Outcome Scale scores of 4 and 5) after GSWH over a 24-month period. METHODS: The authors posited 2 questions: First, what percentage of civilians with GSWH died in the state of Maryland in a given period of time? Second, what were the predictors of favorable outcome after GSWH? The authors examined demographic, clinical, imaging, and acute care data for 786 civilians who sustained GSWH. Univariate and logistic regression analyses were used to analyze the data. RESULTS: Of the 786 patients in this series, 712 (91%) died and 74 (9%) completed acute care in 9 trauma centers. Of the 69 patients admitted to one Maryland center, 46 (67%) eventually died. In 48 patients who were resuscitated, the Injury Severity Score was 26.2, Glasgow Coma Scale (GCS) score was 7.8, and an abnormal pupillary response (APR) to light was present in 41% of patients. Computed tomography indicated midline shift in 17%, obliteration of basal cisterns in 41.3%, intracranial hematomas in 34.8%, and intraventricular hemorrhage in 49% of cases. When analyzed for trajectory, 57.5% of bullet slugs crossed midcoronal, midsagittal, or both planes. Two subsets of admissions were studied: 27 patients (65%) who had poor outcome (25 patients who died and 2 who had severe disability) and 15 patients (35%) who had a favorable outcome when followed for a mean period of 40.6 months. Six patients were lost to follow-up. Univariate analysis indicated that admission GCS score (p < 0.001), missile trajectory (p < 0.001), surgery (p < 0.001), APR to light (p = 0.002), patency of basal cisterns (p = 0.01), age (p = 0.01), and intraventricular bleed (p = 0.03) had a significant relationship to outcome. Multivariable logistic regression analysis indicated that GCS score and patency of the basal cistern were significant determinants of outcome. Exclusion of GCS score from the regression models indicated missile trajectory and APR to light were significant in determining outcome. CONCLUSIONS: Admission GCS score, trajectory of the missile track, APR to light, and patency of basal cisterns were significant determinants of outcome in civilian GSWH.

A rare case of penetrating cranial trauma by knife with direct lesion to the anterior cerebral artery

Las lesiones penetrantes en el cráneo por lo general se asocian con alta mortalidad. Ellos pueden ser el resultado de numerosos eventos, la mayoría de ellos están causados por un trauma de alta energía. La perforación de un cráneo por los objetos de baja energía cinética es inusual en la práctica neuroquirúrgica. Un alto porcentaje de los casos con lesiones penetrantes craneales se asocian con lesiones vasculares, lo que requiere el estudio de la vascularización intracraneal para una conducta médica adecuada. Presentamos un caso de una paciente de 32 años de edad que sufrió un trauma penetrante en el cráneo con un cuchillo a través de los huesos del cráneo, con lesión directa a la arteria cerebral anterior, e incluimos una breve revisión de la literatura sobre el tema.

The penetrating injuries of the skull are usually associated with high mortality. They may be the result of numerous events, the majority of them being caused by high energy trauma. Penetrating brain injury by objects of low kinetic energy is unusual in the neurosurgical practice. A high percentage of the cases with penetrating injuries is associated with cranial vascular lesions, requiring study of the intracranial vasculature for proper management. We report on a case of a 32-year-old patient who suffered a head-penetrating trauma by a knife through the bones of the skull, with direct injury to the anterior cerebral artery, including a brief review of the literature on the theme.

Long-term outcomes of combat casualties sustaining penetrating traumatic brain injury.

BACKGROUND: Previous studies have documented short-term functional outcomes for patients sustaining penetrating brain injuries (PBIs). However, little is known regarding the long-term functional outcome in this patient population. Therefore, we sought to describe the long-term functional outcomes of combat casualties sustaining PBI. METHODS: Prospective data were collected from 2,443 patients admitted to a single military institution during an 8-year period from 2003 to 2011. PBI was identified in 137 patients and constitute the study cohort. Patients were stratified by age, Injury Severity Score (ISS) and admission Glasgow Coma Scale (aGCS) score. Glasgow Outcome Scale (GOS) scores were calculated at discharge, 6 months, 1 year and 2 years. Patients with a GOS score of 4 or greater were considered to have attained functional independence (FI). RESULTS: The mean (SD) age of the cohort was 25 (7) years, mean (SD) ISS was 28 (9), and mean (SD) aGCS score was 8.8 (4.0). PBI mechanisms included gunshot wounds (31%) and blast injuries (69%). Invasive intracranial monitoring was used in 80% of patients, and 86.9% of the study cohort underwent neurosurgical intervention. Complications included cerebrospinal fluid leak (8.3%), venous thromboembolic events (15.3%), meningitis (24.8%), systemic infection (27.0%), and mortality (5.8%). The cohort was stratified by aGCS score and showed significant improvement in functional status when mean discharge GOS score was compared with mean GOS score at 2 years. For those with aGCS score of 3 to 5 (2.3 [0.9] vs. 2.9 [1.4], p < 0.01), 32% progressed to FI. For those with aGCS score of 6 to 8 (3.1 [0.7] vs. 4.0 [1.2], p < 0.0001), 63% progressed to FI. For those with aGCS score of 9 to 11 (3.3 [0.5] vs. 4.3 [0.8], p < 0.0001), 74% progressed to FI. For those with aGCS score of 12 to 15 (3.9 [0.7] vs. 4.8 [0.4], p < 0.00001), 100% progressed to FI. CONCLUSION: Combat casualties with PBI demonstrated significant improvement in functional status up to 2 years from discharge, and a large proportion of patients sustaining severe PBI attained FI. LEVEL OF EVIDENCE: Epidemiologic study, level III.

Outcome of craniocerebral gunshot injuries in the civilian population. Prognostic factors and treatment options.

AIM: Gunshot wounds to the head are rare in Europe. They may be inflicted by low-velocity handguns, captive bolt guns and tear gas cartridges and mostly result from suicide attempts. The experience of neurosurgeons with this kind of traumatic injury is decreasing; the aim of this study was therefore to analyse prognostic factors which help to decide whether or not to operate and to discuss treatment options. METHODS: Thirty patients with gunshot head injuries treated in our hospital from 1993 to 2008 were retrospectively evaluated. Glasgow Coma Scale (GCS) score, pupil reactivity, lesion localisation, number of bone fragments, intracranial pressure (ICP), midline shift, hypotension, and dural penetration were analysed for their prognostic value. Surgically and non-surgically treated patients were evaluated separately. Complications were registered. RESULTS: A low GCS of 3-8, fixed pupils, >2 bone fragments, bilobar or posterior fossa/brainstem lesions and ICP >45 mmHg were indicators of a poor prognosis. CONCLUSION: Patients with a GCS of 3-8 and two non-reactive pupils should not be operated. If one or both of the pupils are reactive, surgery should be performed irrespective of the GCS score, except in patients with translobar/transventricular wounds. Even if there are no clear contraindications to surgery, the outcome is expected to be poor in patients with a low GCS score, midline shift >10 mm, >2 bone fragments in the brain, and a bilobar, posterior fossa/brainstem or ventricular lesion and ICP >45 mmHg. When surgery is performed the wound and the missile or bone track should be debrided meticulously, the wound and dura should be closed in a watertight fashion and antibiotic prophylaxis as well as tetanus serum should be given.

Adolescent Russian roulette deaths.

Adolescence, between the ages of 10 and 19 years, is a unique period both physically and emotionally. During this time of life, individuals are known to experiment and engage in risky behavior, sometimes with unforeseen morbidity and mortality. We also see suicide emerge as a manner of death in this age group. The most common method is gunshot wound and sometimes in the form of Russian roulette. Few studies have looked at deaths by Russian roulette, the victims, and scenarios. In particular, no study examines the adolescent victim of Russian roulette. To better understand and classify this entity, adolescent Russian roulette autopsy cases over a 20-year period were examined looking at the victims, scenarios, autopsy findings, cause and manner of death, and the weapons. All victims were males, ages 13 to 19 years, with a Black-to-White ratio of 1:1. No victim had a previous psychiatric history. Toxicology was positive for alcohol and/or marijuana in 50% of the victims. Friends were present when the victim shot himself which occurred in the home the majority of the time. In all but 1 case, premeditation of the game was involved as the victim provided the weapon for the roulette. The cause of death was gunshot wound to the head (6 to the right side, 1 to the mouth, 1 to the forehead), and the manner of death was suicide in 6 cases and accident in 2 cases. A review of the literature discusses the adolescent victim, suicide, and Russian roulette.

Administration off label of recombinant factor-VIIa (rFVIIa) to patients with blunt or penetrating brain injury without coagulopathy.

Traumatic brain contusions may increase in size over time or may develop at a delay after injury. This may lead to neurological deterioration, long term morbidity or even death. Coagulation disorders after injury can contribute to progression of haemorrhage. Recombinant activated factor VII (rFVIIa) was used in 12 patients with a severe head injury who had no systemic coagulopathy but who were considered to be at risk of progression of their intracranial lesion. Twelve consecutive patients suffering from life-threatening acute head injuries from blunt (3 cases) and penetrating mechanisms were given with rFVIIa, either to prevent the expected development of brain contusion or to assist in bleeding control during surgery. In 11 patients, rFVIIa was given by the attending neurosurgeon. Two of the patients died of their severe penetrating injuries one of whom had severe vasospasm 2 days after administration of rFVIIa. The other 11 patients did not appear to suffer any treatment-related adverse effects. When the drug was given prophylactically to prevent brain resection (6 cases) or to limit the need for widening resection (5 cases), marked control was achieved in seven cases, and a lesser effect was observed in the other 4 cases. We conclude that, in a small and highly individually selected series of patients with severe head injury, the administration of rFVIIa did not lead to adverse effects. Although the majority of patients were considered to be at high risk of progression of their lesions, this occurred in only one. The early use of rFVIIa in head injured patients without systemic coagulopathy may reduce the occurrence of enlargement of contusions, the requirement of further operation, and adverse outcome. Prospective randomised controlled studies are required to investigate this.

TEC por arma de fuego, experiencia del Servicio de Neurocirugía del Hospital de Restauración, Recife, Brasil / TEC fire arm, experience of Neurosurgery Service Restoration Hospital, Recife, Brazil

EI TEC representa un problema de salud pública mundial, siendo una de las tres principales causas de muerte en la población menor de 45 años, lo que constituye un impacto social y económico importante. Sin duda que la principal causa de estos lo constituye los accidentes de tránsito, seguido por los actos de violencia, que en los cambios sociales actuales se hacen cada vez mayor. Es así como en el Hospital de Restauración, Recife, capital de la provincia de Pernambuco en Brasil, éstos últimos contribuyen de manera importante a incrementar el número de admisiones hospitalarias por esta causa. Según datos publicados en prensa local se consignan hasta 5 ingresos por herida de arma de fuego al día en dicho recinto, lo que hace interesante observar y estudiar el manejo que se practica en dicho centro. El presente trabajo es un análisis retrospectivo de datos obtenidos en fichas clínicas, para lo cual se consignaron variables prequirúrgica, quirúrgicas y postquirúrgicas, con el objetivo de valorar el desenlace final en este grupo de pacientes con respecto a la mortalidad durante esa hospitalización, en relación a las variables estudiadas. Es así que se consignó las admisiones del año 2005, representando un universo de I 10 pacientes con TEC por arma de fuego, en donde se observó conducta quirúrgica en 100 pacientes donde se realizó craniectomias descompresivas y craniotomias como conducta inicial, observándose una mortalidad general de un 25 por ciento de los ingresados. Se presenta la siguiente revisión como una amplia experiencia que permita extrapolar conductas en nuestro país, Chile, en donde este tipo de lesiones son infrecuentes en tiempo de paz y así contribuir en la toma de decisiones en el grupo médico enfrentado a estos pacientes.

Herida penetrante intracraneal causada por una tijera: caso clínico / Intracranial penetrating injury caused by a scissors: a case report

El incremento de la violencia relacionada con las armas en general y el subsecuente aumento de las lesiones craneocerebrales penetrantes le conciernen al neurocirujano un papel protagónico. La definición de trauma penetrante es aquel que presenta únicamente orificio de entrada, la morbimortalidad de estas lesiones es alta, en general más del 90 por ciento son provocadas por agresiones, el arma blanca más comúnmente empleada es el cuchillo, le siguen tijeras, clavos, etc. Se realiza una pequeña revisión de la literatura y se presenta un caso clínico en toda su evolución que después de ser agredido con una tijera el examen físico, el Rx simple y la TAC de cráneo, mostraron un fragmento metálico en el compartimiento intracraneal, es llevado de urgencias al salón de operaciones, el paciente se recupera con un ECG de 15 puntos y sin déficit neurológico, no hubo complicaciones infecciosas ni crisis comiciales postoperatorias.

Injuries in combat from 1982-2005 with particular reference to those to the head and neck: A review.

The aim of this review was to examine the range of combat injuries with particular reference to those of the head and neck. We evaluated 10 retrospective studies selected from the period 1982-2005 that covered war injuries from Vietnam, Lebanon, Slovenia, Croatia, Iraq, Somalia, and Afghanistan. We found differences in the causes of injuries. Injuries from fragments were more common during the 90s than during the Vietnam War, where shooting injuries predominated. Injuries to the trunk were reduced in conflicts from 1991 onwards as military personal armour systems including protective vests were used. However, the mortality of wounded soldiers in all conflicts was consistently between 10% and 14%. There was a high incidence of injuries to the head and neck (up to 40%) though they affected only 12% of the body surface area. Though the data from the different military conflicts are not totally comparable, there are trends in the type of injuries and mortality, which may lead to changes in existing systems of medical care.

Penetrating civilian craniocerebral gunshot wounds: a protocol of delayed surgery.

OBJECTIVE: Several factors have led to our unique approach of delayed definitive débridement. We wanted to evaluate the effectiveness of our management and compare it with the existing data in the literature. METHODS: We retrospectively reviewed the records of 194 patients presenting between January 1996 and October 2003 with penetrating craniocerebral gunshot wounds. After exclusion criteria, 125 patients qualified. RESULTS: Of the patients, 88.8% were male. The mean age was 24.9 +/- 10.9 years. In 70.4% of patients, the presenting Glasgow Coma Scale (GCS) score was 3 to 8. Only 38 (30.4%) of the 125 patients survived, with poor outcome in 2 and good outcome in 36. Bilaterally fixed and dilated pupils and bihemispheric tract on computed tomographic scan were significantly related to poor outcome. There were 49 surgical procedures performed on 27 of the patients, with a mortality rate of 7.4%. Of the 38 survivors, 13 underwent no surgery. Average time to surgery was 11.04 days. Total rate of infection was 8%, and it did not influence outcome. No patient presenting with a GCS score of 3 or 4 survived. Seventeen patients attended follow-up, for a total of 3609 days (average, 212 d) and very few late complications. CONCLUSION: Our supportive care of patients is not optimal. We should have saved more of our patients who presented with GCS scores of 14 and 15 who subsequently died. We have been able to report unconventionally late surgical management of two-thirds of survivors, with no surgery in one-third of survivors. Despite a high rate of infectious complications, infection did not lead to death or disability. Our protocol rarely leads to patients surviving in a permanently vegetative state. In the future, we would perform early surgery for patients who present awake and continue our current management for poor-grade patients. In this way, we will improve the number of good outcomes without increasing the population of severely damaged and dependent survivors.

Craniocerebral gunshot wounds: results of less aggressive surgery and complications.

Four hundreds patients who suffered from cranial gunshot wounds injuries were analyzed. Surgical therapy, primary and secondary debridement, including repair of dural defects and removal of retained intracranial bone and metal fragments were applied. Central nervous system infections were mostly observed in cases with cerebrospinal fluid (CSF) fistulas. In 130 of 400 patients, bone and metal fragments were determined on control CT scans. Most of the deaths in this group of patients were attributed to the influence of brain injury and occurred within the first month after injury. Fragments retained after first debridement were followed periodically by CT scans. Surgery was not performed until the infection developed. Retained fragments did not increase the infection risk but high rates of infection did occur in cases with CSF fistulas. The presence of diffuse brain damage, brainstem injury, CNS infection, or ventricular injury was associated with a poor outcome. The prognostic importance of complications such as intracranial haemorrhage, epileptic seizures, hydrocephalus, was also investigated.

Civilian gunshot wounds to the brain.

BACKGROUND: Civilian gunshot wounds to the brain are relatively rare, and a much-neglected subject in Taiwan. We present our experience with 16 patients who sustained gunshot wounds to the brain, and then identify factors determining the respective outcomes. METHODS: From 1988-2002, data from 16 patients with civilian gunshot wounds to the brain, who were treated at Taichung Veterans General Hospital, were retrospectively reviewed. Historical information, clinical manifestations, and imaging findings were described. Based on Glasgow Outcome Score (GOS), patients were divided into a poor-outcome group (GOS, 1-2) and satisfactory-outcome group (GOS, 3-5) for further analysis. RESULTS: The overall mortality rate was 31.3% (5 of 16 patients). Thirteen patients underwent surgery, and the surgical mortality rate was 15.4% (2 of 13 patients). Of the 7 patients with a Glasgow Coma Scale (GCS) score of more than 8, all survived with satisfactory outcomes; of the 9 patients with a GCS score of less than 8, 8 had poor outcomes (5 died, and 3 were in a persistent vegetative state); p < 0.005 between the 2 GCS groups. In addition, the rate of satisfactory outcome was significantly higher in 7 patients with limited brain injury, as determined by computed tomography (CT) scan, than in 8 patients with extensive brain injury (86% vs 25%; p < 0.05). CONCLUSION: GCS score on admission, and the extent of brain injury as visualized by CT scan, seem to be the 2 most significant predictors of outcome in cranio-cerebral gunshot wounds. Patients with a GCS score of more than 8, or brain lesions limited to a single lobe of the brain, may benefit from aggressive management.
