Long-term outcome in elderly patients after operation for traumatic intracranial hemorrhage.

OBJECTIVE: This study examined outcomes in elderly TBI patients who underwent a cranial operation. METHODS: We identified TBI patients > or = 65 who underwent a cranial operation from January 1, 2004 to December 31, 2008. Data collected included: age, admission GCS, mechanism of injury, ISS, Head AIS, type of operation, hemorrhage acuity, time to operation, pre-hospital warfarin or clopidogrel, and in-hospital death. Survivors were contacted by phone to determine an Extended Glasgow Outcome Score (GOSE). A favorable outcome was defined as having a GOSE of > or = 5 at follow-up, an unfavorable outcome was defined as: in-hospital death, death within one year of injury, and a GOSE < 5 at follow-up. Chi-square and student's t-test were used. RESULTS: One hundred sixty-four elderly TBI patients underwent cranial surgery. Mean age was 79.2 +/- 7.6 years. Most patients: had a ground level fall (86.0%), suffered a subdural hematoma (95.1%), and underwent craniotomy (89.0%). Twenty-eight percent died in the hospital and another 20.1% died within one year. Fifty-six patients were eligible for a GOSE interview of these: 17 were lost to follow-up, seven refused the GOSE interview, 22 had a GOSE > or = 5, and ten had a GOSE < 5. Mean follow-up was 42.6 +/- 14.9 months. Of all the factors analyzed, only older age was associated with an unfavorable outcome. CONCLUSIONS: While age was associated with outcome, we were unable to demonstrate any other early factors that were associated with long-term functional outcome in elderly patients that underwent a cranial operation for TBI.

A unique case of malignant neoplasm--choriocarcinoma in a 24-year-old man--difficulties in differential diagnostics of intracranial injuries in the aspect of medicolegal opinion / Niezwykle rzadki przypadek nowotworu zlosliwego--kosmówczaka u 24-letniego mezczyzny--trudnosci w diagnostyce róznicowej uszkodzen sródczaszkowych w aspekcie opiniowania sadowo-lekarskiego.

Differential diagnostics of pathologic and traumatic lesions based on image techniques may in some cases cause serious difficulties or even be the cause of a medical error resulting in incorrect medicolegal opinion. The authors present a unique case of primary malignant neoplasm of the testicle (choriocarcinoma) in a 24-year-old man. Several days after the event, he was admitted to Department of Neurology with CT-confirmed traumatic intracerebral hematoma communicating with the ventricular system. Discharged in a good general condition, the patient died several days later. A postmortem examination combined with histopathology demonstrated numerous metastases of the primary carcinoma, which also involved the brain, arousing suspicions of head injury in consequence of a crime.

[Fatal crossbow injury in an adolescent]. / Tödliche Armbrustverletzung im Jugendalter.

The authors present the case of a 14-year-old boy who died while handling a crossbow, which was a gift from a friend's mother. The bolt passed through the right nostril, penetrated the sinus sphenoidalis, the brain stem, the left occipital lobe and the occipital calvaria. Immediately after the accident, the victim was taken to a maximum care hospital. In spite of neurosurgical treatment and intensive care the victim died 4 days later. The case presented demonstrates that crossbows are not suitable as toys for underage persons, as they are deadly weapons which can cause serious penetrating injuries. In Germany, no license is required to buy and/or possess crossbows. In the authors' opinion, legal restrictions on the sale of crossbows and a special training of the users would be reasonable measures to reduce such accidents.

Paediatric Trauma Score as a non-imaging tool for predicting intracranial haemorrhage in patients with traumatic brain injury.

To identify a useful non-imaging tool to screen paediatric patients with traumatic brain injury for intracranial haemorrhage (ICH). We retrospectively analysed patients aged < 15 years who visited the emergency department with head trauma between January 2015 and September 2020. We divided patients into two groups (ICH and non-ICH) and compared their demographic and clinical factors. Among 85 patients, 21 and 64 were in the ICH and non-ICH groups, respectively. Age (p = 0.002), Pediatric trauma score (PTS; p < 0.001), seizure (p = 0.042), and fracture (p < 0.001) differed significantly between the two groups. Factors differing significantly between the groups were as follows: age (odds ratio, 0.84, p = 0.004), seizure (4.83, p = 0.013), PTS (0.15, p < 0.001), and fracture (69.3, p < 0.001). Factors with meaningful cut-off values were age (cut-off [sensitivity, specificity], 6.5 [0.688, 0.714], p = 0.003) and PTS [10.5 (0.906, 0.81), p < 0.001]. Based on the previously known value for critical injury (≤ 8 points) and the cut-off value of the PTS identified in this study (≤ 10 points), we divided patients into low-risk, medium-risk, and high-risk groups; their probabilities of ICH (95% confidence intervals) were 0.16-12.74%, 35.86-89.14%, and 100%, respectively. PTS was the only factor that differed significantly between mild and severe ICH cases (p = 0.012). PTS is a useful screening tool with a high predictability for ICH and can help reduce radiation exposure when used to screen patient groups before performing imaging studies.

Prothrombin complex concentrate for vitamin K antagonist reversal in traumatic intracranial hemorrhage.

OBJECTIVE: Administration of prothrombin complex concentrate (PCC) is recommended for vitamin K antagonist (VKA) reversal in patients with severe bleeding complications. However, there are only limited data available on its use for VKA reversal in patients with traumatic intracranial hemorrhage (ICH). METHODS: Data from all anticoagulated patients referred to our hospital for treatment of traumatic ICH and who received PCC for anticoagulation reversal were retrospectively analysed with specific focus on bleeding and thromboembolic complications during the further in-hospital course. RESULTS: A total of 142 patients were included in the present study. The median age was 78 years (Interquartile range [IQR]: 72-84) and the median Glasgow Coma Scale (GCS) score on admission was 12 (IQR: 7-14). Median International Normalized Ratio (INR) on admission was 2.5 [IQR: 2.0-3.3] and decreased to 1.2 [IQR: 1.1-1.3] following administration of a median dose of 2000 I.U. PCC [IQR: 1500-2625]. The in-hospital mortality rate was 13% and the median GCS of survivors at discharge was 14 [IQR: 12-15]. Thromboembolic events after PCC administration occurred in 4 patients (2.8%). The overall one-year mortality rate in this patient cohort was 49%. CONCLUSIONS: PCC administration rapidly normalises INR and facilitates urgent neurosurgical procedures in anticoagulated patients with traumatic ICH.

Effect of Chronic Alcoholism on Traumatic Intracranial Hemorrhage.

BACKGROUND: Traumatic intracranial hemorrhage (TICH) is one of the commonest indications for neurosurgical consultation after trauma. Worsening neurologic examination results, size of initial TICH, presence of displaced skull fracture, and concomitant anticoagulant use at the time of injury drive the recommendations for repeat computed tomography of head (RCTH), to assess for stability of intracranial hemorrhage. Chronic alcohol use is not generally considered an indication for repeat head computed tomography (CT). METHODS: A retrospective study of 423 patients with TICH with normal admission platelet (PLT) counts was reviewed for this study, taken as a subset of 1330 patients with TICH admitted to Lahey Hospital and Medical Center over a 3-year period. Of these 423 patients, 330 were classified as nonalcoholics and 93 were classified as alcoholics, based on whether alcohol use disorder was documented in the patient's medical record, present before injury. The normal PLT level was defined as ≥100,000 µ/L. Patients were excluded from review if they had comorbid conditions that could cause PLT dysfunction or coagulopathy. Continuous and categorical variables were compared using independent t test and χ2, respectively. Binary logistic regression was used to predict outcome: stable versus worsening of TICH on RCTH. Statistical analysis was conducted using SPSS version 25. RESULTS: The mean age of the nonalcoholic and alcoholic cohorts were 71.9 years and 54.8 years, respectively. A significantly higher percentage of alcoholics were male. There was a statistically significant difference (χ2 = 8.14; P < 0.004) in radiologic progression of TICH between the 2 groups, with the alcoholics having a worsening RCTH 16.1% of the time compared with only 6.7% in nonalcoholics. Chronic alcohol use was an independent predictor of radiologic progression in patients with normal PLT level (odds ratio, 2.69; confidence interval, 1.34-5.43; P < 0.006). CONCLUSIONS: Chronic alcohol use was an independent predictor of radiologic progression of TICH in the setting of normal PLT level. Modification of this risk of progression with transfusion of fresh PLTs in chronic alcoholic patients with TICH needs to be investigated in a prospective trial.

Repeat Surgery After Decompressive Craniectomy for Traumatic Intracranial Hemorrhage: Outcomes and Predictors.

INTRODUCTION: Repeat surgery (RS) after decompressive craniectomy/craniotomy (DC) for traumatic intracranial hemorrhage (TICH) is a devastating complication. In patients undergoing DC for TICH, we sought to 1) describe the population requiring RS, 2) compare outcomes of those requiring RS with those who did not, and 3) discern RS predictors. METHODS: A single-institution retrospective case-control study was conducted from 2000 to 2015. Inclusion criteria were DC for acute supratentorial TICH (subdural hemorrhage, epidural hemorrhage, and intraparenchymal hemorrhage) and ≥7 day survival. Patients underwent RS within 7 days of DC; controls did not require RS. Outcomes and predictors of RS were evaluated with univariate and multivariate logistic regression (MLR). RESULTS: Of 201 patients requiring DC, 28 (14%) underwent RS. Common mechanisms were ground-level fall (45%) and motor vehicle collision (29%). Anticoagulation/antiplatelet medication was used by 44 patients (21%). Subdural hemorrhage was the most common hemorrhage (64%). Using MLR, those requiring RS were more likely to experience major complications (odds ratio [OR], 22.6; 95% confidence interval [CI], 5.06-101.35; P < 0.001) and in-hospital mortality (OR, 2.76; 95% CI, 1.02-7.43; P = 0.045) and be dead/dependent at 6 months (OR, 2.50; 95% CI, 1.08-5.82; P = 0.033) and 2 years (OR, 2.44; 95% CI, 0.99-6.00; P = 0.051). Predictors of undergoing RS identified by MLR were smaller hemorrhage (OR, 0.32; 95% CI, 0.13-0.78; P = 0.012), larger midline shift (OR, 4.40; 95% CI, 1.43-13.51; P = 0.010), and better preoperative Glasgow Coma Scale score (OR, 1.28; 95% CI, 1.13-1.46; P < 0.001). CONCLUSIONS: Patients requiring RS after DC represent a heterogenous population with worse outcomes. Although the identified risk factors for RS are not modifiable, surgeons should be aware of these factors during the initial surgery.

Repetitive cortical spreading depolarizations in a case of severe brain trauma.

OBJECTIVE AND IMPORTANCE: Cortical spreading depolarizations (CSD) are waves of mass tissue depolarization that mediate progressive development of cortical infarction in animal models and occur in approximately 50% of patients with acute brain injury. Here we performed multi-modal cerebral monitoring to investigate pathologies associated with CSD occurrence in a case of severe traumatic brain injury. CLINICAL PRESENTATION: A 20 years old male suffering severe traumatic brain injury from a fall had extensive frontal subdural and intraparenchymal hemorrhage with mass effect. Craniectomy was performed for hematoma evacuation and decompression. INTERVENTION: During surgery, a subdural electrocorticography (ECoG) electrode strip, along with microdialysis and PtiO2 probes, was placed beside injured cortex for CSD monitoring. Within 13-81 hours post-injury, 34 CSD occurred. CSD incidence increased during spontaneous hyperthermia and decreased during induced normothermia. Periods of CSD activity were also associated with low brain glucose (<0.10 mmol/l), elevated glutamate (>40 mmol/l) and lactate/pyruvate (>40), and PtiO2<10 mmHg. CSD caused progressive deterioration of ECoG activity only in regions with infarction at follow-up on day 27. CONCLUSION: Repetitive mass tissue depolarizations accompanied a negative course of hemorrhagic lesion progression in the presence of ischemic conditions after traumatic brain injury. Whether as cause or effect, CSD may represent an inherent component of progressive metabolic failure leading to tissue death, and temperature appears to be an important factor influencing their occurrence. Continuous ECoG is a valuable tool for monitoring subclinical events such as CSD and seizures and for translational research in acute brain injury mechanisms and therapeutics.

Does the Presence of Subdural Hemorrhage Increase the Risk of Intracranial Hemorrhage Expansion after the Initiation of Antithrombotic Medication?

Patients with traumatic intracranial hemorrhage (ICH) with a clinical indication for antithrombotic medication present a clinical dilemma, burdened by the task of weighing the risks of hemorrhage expansion against the risk of thrombosis. We sought to determine the effect of subdural hemorrhage on the risk of hemorrhage expansion after administration of antithrombotic medication. Medical records of 1626 trauma patients admitted with traumatic ICH between March 1, 2008, and March 31, 2013, to a Level I trauma center were retrospectively reviewed. The pharmacy database was queried to determine which patients were administered anticoagulant or antiplatelet medication during their hospitalization, leaving a sample of 97 patients that met inclusion criteria. Patients presenting with subdural hemorrhage were compared with patients without subdural hemorrhage. Demographic data, clinically significant expansion of hematoma, postinjury day of initiation, and mortality were analyzed. A total of 97 patients met inclusion criteria with 55 patients in the subdural hemorrhage group and 42 in the other ICH group. There were no significant differences in age, gender, injury severity score, admission Glasgow coma score, or mean hospital day of antithrombotic administration between the groups. Patients with subdural hemorrhage had a significantly higher rate of ICH expansion (9.1 vs 0%, P = 0.045). There was no difference in overall hospital mortality between the two groups. Incidence of ICH expansion was higher in patients with subdural hemorrhage. It may be prudent to use special caution when administering antiplatelet or anticoagulant medication in this group of patients after injury.

The Relationship Between Hematoma and Pachymeninges in an Interdural Hematoma: Diagnosis and Surgical Strategy.

BACKGROUND: The exact location of a hematoma in relation to the pachymeninges contributes to typical radiographic presentations. However, because of the complexity of hematoma evolution and neomembrane formation, an unexpected intraoperative finding can lead to a change of surgical strategy. In addition, the concentration of hemoglobin and its degradation products, the integrity of red blood cells, and the infiltration of fibroblasts, polymorphonuclear neutrophils, and macrophages are factors that affect the imaging characteristics on computed tomography and magnetic resonance imaging as the hematoma ages. CASE DESCRIPTION: An interdural hematoma (IDH)-a hemorrhage that splits the periosteal dura mater from the meningeal dura mater-is an extremely rare occurrence, and the diagnosis requires confirmation by surgical or pathologic findings. By presenting a case of an IDH that was misdiagnosed as a chronic subdural hematoma before surgery, and reviewing the literature, we propose the radiologic characteristics of presenting both dural border sign and dural beak sign on magnetic resonance imaging as a specific indicator for IDH preoperatively. CONCLUSIONS: A careful evaluation of cerebral expansion before membranectomy was mandatory intraoperatively. For IDH, wide inner membranectomy (i.e., excision of meningeal dura mater) should not be necessary. An IDH should be considered as a distinct disease category when evaluating an extra-axial hematoma despite its rarity, because the characters of radiologic, histopathologic findings are different. In addition, surgical strategy varies for epidural or subdural hematoma in different hematoma stages.

Traumatic midbrain hematoma in a patient presenting with an isolated palsy of voluntary facial movements. Case report.

The authors report on the case of a young man with a mild head injury and an isolated palsy of voluntary facial movements, attributed to a midbrain traumatic hematoma. This exception to the generally accepted conjunction between brainstem contusion and poor prognosis pertains to a special entity of midbrain laceration due to hyperextension of the head, with minimal influence on the level of consciousness. The clinical presentation of this lesion with facial palsy sparing emotion-related movement has rarely been described and offers a clue for exploring the neuroanatomy of facial movement.

Cortical spreading depression and peri-infarct depolarization in acutely injured human cerebral cortex.

Electrocorticographic (ECoG) activity was recorded for up to 129 h from 12 acutely brain-injured human patients using six platinum electrodes placed near foci of damaged cortical tissue. The method probes ECoG activity in the immediate vicinity of the injured cortex and in adjacent supposedly healthy tissue. Six out of twelve patients displayed a total of 73 spontaneous episodes of spreading depression of the ECoG. Of the remaining 6 patients 1 displayed an episode of synchronous depression of ECoG during surgery. Using the same electrodes we also measured the slow potential changes (SPC) (0.005-0.05 Hz) to test the hypothesis that the ECoG depressions were identical to Leao's cortical spreading depression (CSD), and to be able to record peri-infarct depolarisations (PIDs) in electrically 'silent' cortical tissue. Changes in the SPC indicate depolarization of brain tissue. For the analysis, the SPCs were enhanced by calculating the time integral of the ECoG signal. Spreading ECoG depressions were accompanied at every single recording site by stereotyped SPCs, which spread across the cortical mantle at 3.3 (0.41-10) mm/min (median, range), i.e. at the same speed of spread as the depression of the ECoG activity. The amplitude of the SPCs was 0.06-3 mV. In 4 out of 6 patients the ECoG recovered spontaneously. In 2 patients we subsequently recorded recurrent SPCs, but without recovery of the initial ECoG background activity until 2-5 h later. This represents the first direct recording of PIDs in acutely injured human brain. Evidence from this and our previous study of 14 brain-injured patients suggests that CSDs in acute brain disorders occur at higher incidence in patients <30 years (83%) than above (33%). CSD was recorded in 4 out of 5 traumatic brain injury patients, and in 2 out of 7 patients with spontaneous haemorrhages. We conclude that the spreading ECoG depressions recorded in patients are identical to CSDs recorded in animal experiments. We furthermore provide direct electrophysiological evidence for the existence of PIDs and hence a penumbra in the human brain. We hypothesize that the depolarization events might contribute to tissue damage in acute disorders in the human brain.

[Expression of synaptophysin in experimental diffuse brain injury].

OBJECT: To investigate the changes in the expression_level of synaptophysin following diffuse brain injury (DBI) in rats and to correlate the changes of the synaptophysin expression_level with the post injury time interval. METHODS: Wister rats were used as a DBI model induced by Marmarou method. The changes of synaptophysin immunoreactivity on coronal sections of the rats sampled at different post-injury time intervals were used as a marker. The densitometry of the synaptophysin immunoreactivity was documented by imaging technique and analyzed by SPSS software. RESULTS: The expression level of synaptophysin in DBI rats showed dynamic changes following DBI as well as during the repairing period. CONCLUSION: The changes of synaptophysin level may be used as a marker for estimation of the post injury time interval in DBI.

Lesson of the month 2: Contusion confusion.

This lesson of the month highlights that certain radiology terminology may be used to report bleeding on head computerised tomography (CT) reports. On-call junior doctors should not be expected to interpret CT head images, so often their decisions will be based on the written report. The wording used can change the clinical decision and therefore the treatment given by a junior doctor. Clinical teams and junior doctors should be educated on terminology in relation to bleeding on CT head reports.

[Changes in regional meningeal immunity in local immunomodulating therapy in patients with acute traumatic intracranial hematomas].

A clinicomorphological study of 660 patients with acute traumatic intracranial hematomas has shown that pneummonia develops in 56% of cases, intracranial complications (purulent meningitis) in 14%.Pyoinflammatory complications were 1.5-1.7 times less common in small-sized hematomas, their total rate and the rate of pneumonias was twice higher in left cerebral hemispheric lesion. On the contrary, intracranial complications were twice more common in right cerebral hemispheric lesion. The structural bases of the regional meningeal immunity system were as follows: the pathways of blood and spinal fluid circulation and dural arachnoidal intercellular fluid; cellular cooperation of the meninx and tissue of the brain; the network of lymph vessels of the dura mater encephali and adventitia of large blood vessels and middle and inferior jugular (regional) lymph nodes. Morphodunctional changes in the local meningeal immunity system in patients with hematomas point to the development of secondary immunodeficiency. Inclusion of regional immunotherapy with T-activin into multimodality treatment decreases the incidence of extra- and intracranial pyoinflammatory complications and mortality.

Application of optical methods in the monitoring of traumatic brain injury: A review.

We present an overview of the wide range of potential applications of optical methods for monitoring traumatic brain injury. The MEDLINE database was electronically searched with the following search terms: "traumatic brain injury," "head injury," or "head trauma," and "optical methods," "NIRS," "near-infrared spectroscopy," "cerebral oxygenation," or "cerebral oximetry." Original reports concerning human subjects published from January 1980 to June 2015 in English were analyzed. Fifty-four studies met our inclusion criteria. Optical methods have been tested for detection of intracranial lesions, monitoring brain oxygenation, assessment of brain perfusion, and evaluation of cerebral autoregulation or intracellular metabolic processes in the brain. Some studies have also examined the applicability of optical methods during the recovery phase of traumatic brain injury . The limitations of currently available optical methods and promising directions of future development are described in this review. Considering the outstanding technical challenges, the limited number of patients studied, and the mixed results and opinions gathered from other reviews on this subject, we believe that optical methods must remain primarily research tools for the present. More studies are needed to gain confidence in the use of these techniques for neuromonitoring of traumatic brain injury patients.

Fall from a car driving at high speed: A case report.

In cases of falls, the key issue for forensic scientists is to determine the manner of death. They must distinguish between accidental falls, suicidal falls, falls including blows and falls caused by a blow. Several strategies have been proposed in the literature to help explain injury patterns. Here, we report an original case of a man who died after jumping from a car moving at high speed. A mathematical and modeling approach was developed to reconstruct the trajectory of the body in order to understand the injury pattern and apparent discrepancy between the high speed of the car from which the victim jumped and the topography of the bone fractures, which were limited to the skull. To define the initial values of the model's parameters, a technical vehicle evaluation and several test jumps at low speed were carried out. We studied in greater detail the trajectory of three characteristic points corresponding to the dummy's center of gravity, head and right foot. Calculations were made with and without the air friction effect to show its influence. Finally, we were successful in modeling the initial trajectory of the body and the variation of its head energy over time, which were consistent with the injuries observed.

Severe craniofacial fractures with frontobasal involvement and cerebrospinal fluid fistula: indications for surgical repair.

BACKGROUND: The management of posttraumatic cerebrospinal fluid (CSF) fistulae is a controversial topic. Although recent literature shows that endoscopic repair of CSF fistula is efficacious and minimally invasive, in specific conditions open operative approach remains imperative. METHODS: A series of 36 patients underwent surgery for posttraumatic CSF fistula according to specific selection criteria. These criteria included: bone displacement more than 1 cm (5 cases), location of fracture in proximity to the midline (6 cases), involvement of cribriform plate (12 cases), presence of encephalocele (3 cases), and failure of the conservative treatment (10 cases). The dural defect was closed using vascularized pericranium and fibrin glue. Closure of the basal bone defect was necessary in very large fractures or in special localization of the fistula, such as near the optic nerve. Mean clinical follow-up was 5.7 years. RESULTS: Two patients presented meningitis without sequelae, and 12 with hyposmia. One patient died of the severity of the primary brain injury and associated extracranial lesions. None of the patients had recurrence. CONCLUSIONS: Our results indicate that surgical dural repair in selected cases is related to low morbidity and mortality preserving from delayed risks such as recurrence and infections.

Childhood casualties during civil war: Syrian experience.

In war areas a lot of children die as well as adults. According to UNICEF, almost 2 million children have died in the wars took place in the last 10 years. In this study, we aimed to evaluate demographical data and injury characteristics of Syrian children who were wounded in Syria Civil War and died while being treated in Turkey. Postmortem examination and autopsy reports of 985 forensic deaths from Hatay -a Syrian neighborhood city of Turkey-between January 2012 and August 2014 were analyzed retrospectively. Among 763 Syrian people who were wounded in the war and died while being treated in Turkey, 140 cases (18.3%) who were younger than 18 years of age were taken into the scope of this study. Among those cases 77.9% (n = 109) were male and 22.1% were female. Median ages of female cases are 14 (min-max: 2-18) and median age of female cases are 9 (min-max: 1-18). Frequency distribution is highest between 13 and 18 years of age (n: 71, 50.7%). In 70% (n: 98) of cases, cause of death is bombing and shrapnel injuries, 13.6% (19) of them were killed by gunshot wounds. According to injury sites most of the injuries were reported to be on multiple body parts (54.3%, n: 76) and only head and neck injuries (%30). Cause of death was intracranial bleeding and cerebral parenchymal injury in most of the cases (n: 66, %47.1) followed by vascular damage with external bleeding (n: 15, %10.7) and internal organ damage with internal bleeding (n: 15, %10.7). The cases had very high level Abbreviated Injury Scales and Injury Severity Sores. In conclusion, a lot of children have died in the Civil War of Syria. Their average abbreviated injury scale and injury severity score values reported very high. Children that we evaluated were mostly died of head and neck injuries predominantly caused by bombing attacks and Autopsies of them revealed fatal intracranial hemorrhages and parenchymal injuries.

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.
