Multidisciplinary management of thoracic esophageal fistula secondary to traumatic upper thoracic fracture (T3-4) with associated discitis/osteomyelitis and spinal epidural abscess: illustrative case.

BACKGROUND: An esophageal fistula secondary to a traumatic upper thoracic (T3-4) fracture with resultant thoracic discitis/osteomyelitis and an epidural abscess with neurological compromise is a rare clinical entity. Early diagnosis is critical for an optimal clinical outcome avoiding grave and progressive spinal dissemination with structural instability and neurological deterioration. OBSERVATIONS: The following case, not clearly described previously in the literature, highlights the clinical course and multidisciplinary approach to management including a single-stage posterior cervicothoracic (C3-T6) decompression with vertebral reconstruction with an expandable interbody cage (T2-4) and posterior cervicothoracic fusion and instrumentation (C3-T6), followed by direct esophageal fistula closure with AlloDerm and a vascularized latissimus dorsi muscle flap. LESSONS: Early diagnosis and the potential treatment of a posttraumatic esophageal fistula requires a multidisciplinary approach.

Traumatic abdominal wall hernias: a single-center case series of surgical management.

BACKGROUND: Traumatic abdominal wall hernias (TAWHs) are a rare clinical entity that can be difficult to diagnose and manage. There is no consensus on management of TAWH due to its low incidence and complex concomitant injury patterns. We hereby present the largest single-center case series in the USA to characterize associated injury patterns, identify optimal strategies for hernia management, and determine outcomes. METHODS: Patients who presented with a TAWH from blunt trauma requiring operative management were retrospectively identified over a 14-year period. Demographic data, Injury Severity Score (ISS), associated injuries, type of repair, durability of repair, and complications were collected, and descriptive statistics were calculated. RESULTS: Fifteen patients were identified. The average age was 31±11 years, ISS 15±9, and body mass index 33.4±7.1 kg/m2. Mechanisms included falls (13%), motor vehicle collisions (60%), motorcycle accidents (20%), and pedestrian versus motor vehicle collisions (7%). The most commonly associated injuries included colonic injuries (53%), long bone fractures (47%), pelvic fractures (40%), and small bowel injuries (33%). Nineteen hernia repairs were performed: 6 underwent primary suture repair (32%) and 13 used mesh (68%). There were four recurrences. We could not find any significant relationship between contamination and mesh use or recurrence. There was one mortality related to sepsis. DISCUSSION: TAWHs have an associated injury pattern involving fractures and abdominopelvic visceral injuries where a tailored approach is advisable. Without hollow viscous injuries and gross contamination, these hernias can be repaired safely with mesh in the acute setting. However, in patients with gross contamination or hemodynamic instability, the risk of recurrence with primary repair must be weighed against the risk of infection and prolonged surgery with mesh repair. In those cases, a delayed reconstruction in the elective setting may be optimal.

Guillain-Barré Syndrome After a Gunshot Wound to the Thoracic Spine.

BACKGROUND: Guillain-Barré syndrome (GBS) is a rare but well-documented cause of paralysis, often occurring after infection. Few cases have been reported in association with spinal cord injury (SCI), which masks the characteristic ascending paralysis. To our knowledge, this is the first reported case of confirmed GBS during the clinical course of thoracic paraplegia due to a gunshot wound (GSW). CASE DESCRIPTION: A 23-year-old male presented with a GSW to the right axilla that lodged in the spinal canal at the level of T4, causing right hemothorax and American Spinal Injury Association A paraplegia. He had full strength in bilateral upper extremities until 2 weeks after the injury, at which time he developed progressive weakness in the arms with associated paresthesias and dyspnea. Within 5 days, he was intubated and nearly quadriplegic. Cerebrospinal fluid analysis and electromyography led to a diagnosis of GBS. He was treated with plasmapheresis and experienced rapid and marked recovery in respiratory and upper extremity motor function. CONCLUSIONS: The differential diagnosis for new-onset weakness in patients with GSW-induced SCI is complicated by the inability to obtain magnetic resonance imaging. This unique case of GBS in a patient with T4 paraplegia highlights the importance of obtaining a thorough history and using diagnostic tools to explore possibilities beyond surgery.

Major venous injury and large volume crystalloid resuscitation: A limb threatening combination.

INTRODUCTION: Major venous injury (MVI) affecting the lower extremity can result in subsequent amputation. The contribution of intraoperative resuscitation efforts on the need for amputation is not well defined. We hypothesized that intraoperative large volume crystalloid resuscitation (LVCR) increases the risk of amputation after MVI, while massive transfusion (MT) does not. METHODS: We performed a retrospective review of patients with infrarenal MVI from 2005 to 2015 at seven urban level I trauma centers. The outcome of interest was the need for secondary amputation. RESULTS: 478 patients were included. 31 (6.5%) patients with MVI required amputation. LVCR(p < 0.001), combined arterial/venous injury (p = 0.001), and associated fracture (p = 0.001) were significant risk factors for amputation. MT did not significantly increase amputation risk (p = 0.44). Multivariable logistic regression model demonstrated that patients receiving ≥5L LVCR(aOR (95% CI): 9.7 (2.9, 33.0); p < 0.001), with combined arterial/venous injury (aOR (95% CI):3.6 (1.5, 8.5); p = 0.004), and with an associated fracture (aOR (95% CI):3.2 (1.5, 7.1); p = 0.004) were more likely to require amputation. CONCLUSION: Patients with MVI who receive LVCR, have combined arterial/venous injuries and have associated fractures are more likely to require amputation. MT was not associated with delayed amputation.

Neurosurgical Outcomes of Isolated Hemorrhagic Mild Traumatic Brain Injury.

Introduction Mild traumatic brain injury (TBI) is common but its management is variable. Objectives To describe the acute natural history of isolated hemorrhagic mild TBI. Methods This was a single-center, retrospective chart review of 661 patients. Inclusion criteria were consecutive patients with hemorrhagic mild TBI. Exclusion criteria were any other acute traumatic injury and significant comorbidities. Variables recorded included neurosurgical intervention and timing, mortality, emergency room disposition, intensive care unit (ICU) length of stay (LOS), discharge disposition, repeat computed tomography head (CTH) indications and results, neurologic exam, age, sex, Glasgow Coma Scale (GCS) score, and hemorrhage type. Results Overall intervention and unexpected delayed intervention rates were 9.4% and 1.5%, respectively. The mortality rate was 2.4%. A 10-year age increase had 26% greater odds of intervention (95% CI, 9.6-45%; P<.001) and 53% greater odds of mortality (95% CI, 11-110%; P=.009). A one-point GCS increase had 49% lower odds of intervention (95% CI, 25-66%; P<.001) and 50% lower odds of mortality (95% CI, 1-75%; P=.047). Subdural and epidural hemorrhages were more likely to require intervention (P=.02). ICU admission was associated with discharge to an acute care facility (OR, 2.9; 95% CI, 1.4-6.0; P=.003). Neurologic exam changes were associated with a worsened CTH scan (OR, 12.3; 95% CI, 7.0-21.4; P<.001) and intervention (OR, 15.1; 95% CI, 8.4-27.2; P<.001). Conclusions Isolated hemorrhagic mild TBI patients are at a low, but not clinically insignificant, risk of intervention and mortality.

Trends in demographics and outcome of patients presenting with traumatic brain injury.

OBJECTIVE: To analyze the trends in demographics and outcomes of patients presenting with traumatic brain injury by performing a retrospective database review of the Illinois Department of Public Health (IDPH) Trauma Registry. METHODS: We utilized the IDPH Trauma Registry to retrieve data on patients treated for traumatic brain injuries at our large, tertiary care hospital from 2004 to 2012, inclusive. From this data, logistic regression models were used to analyze and compare basic demographics such as age, sex, and clinical outcome. RESULTS: Three thousand and thirty-nine patients were analyzed with a mean age of 43 (standard deviation, 24) and a median age of 41 (interquartile range, 23 to 60). Over the study period, patients' age increased steadily from 32 to 49 years. The percentage of female patients increased, from 16.4% to 27.5% over the last 4 years. Overall mortality was greater for males than females (22.1% vs. 17.3%; odds ratio [OR], 1.36; 95% confidence interval [CI], 1.10 to 1.68). Mortality decreased over the period (OR, 0.88; 95% CI, 0.85 to 0.91), with a greater decrease in females (OR, 0.84; 95% CI, 0.78 to 0.90) than in males (OR, 0.90; 95% CI, 0.86 to 0.94). CONCLUSION: Although the age of patients presenting with traumatic brain injury is increasing substantially, the data suggests that overall mortality appears to be decreasing, and this decrease appears to be greater in females than in males. These changes in trends found in the IDPH Trauma Registry supports the importance for further analysis of other reliable public datasets to identify areas of future study.

Surgical treatment for a case of coronary steal from a traumatic coronary artery-cameral fistula after blunt cardiac injury.

INTRODUCTION: Blunt cardiac trauma covers a spectrum of injuries from clinically insignificant myocardial contusions to lethal ruptures of cardiac valves and chambers. Traumatic coronary artery-cameral fistulas (TCAF) are a rare sequelae of blunt chest trauma. CASE PRESENTATION: A 53-year-old male developed a TCAF after a motor vehicle collision. He was found on admission to be in cardiogenic shock with an elevated troponin and intermittent bifascicular block. An echocardiogram revealed hypokinesis of the mid-anteroseptal myocardium with an ejection fraction of 50%. Cardiac catheterization revealed a pseudoaneurysm of the left anterior descending artery (LAD) with a fistulous connection to the right ventricle, shown to be associated with reversible anterior wall ischemia from distal LAD coronary steal phenomenon on a nuclear perfusion scan. Given the ischemic burden, he was treated with operative revascularization via a single vessel coronary artery bypass graft (CABG) using the left internal mammary artery to LAD. DISCUSSION: Early repair of TCAF can halt the progression of complications like left-to-right shunting, pulmonary hypertension, and heart failure. The two best described operative approaches to surgical closure of the fistula are either via external ligation or direct repair from within the recipient chamber, possibly with bypass grafting distal to the fistula site. Transcatheter closure and conservative management has been described for select patients with iatrogenic fistulas in recent literature. CONCLUSION: High levels of clinical suspicion are necessary for the early detection and intervention of TCAF. Surgical or transcatheter interventions including fistula ligation and CABG can prevent later complications of heart failure.

The modified Ravitch approach for the management of severe anterior flail chest with bilateral sternochondral dislocations: a case report.

The management of flail chest continues to evolve as scientific evidence and surgical experience accumulates. Flail chest injuries that span the sternum present a rare and complicated injury pattern that can be challenging to manage both medically and surgically. Our patient is a 69-year-old involved in a high-speed motor vehicle crash with respiratory failure secondary to an anterior flail chest. Tomographic examination confirmed a sternal fracture with bilateral sternochondral dislocations and multiple rib fractures. The rib fractures created a lateral flail segment which extended towards the right side. An open Pectus exposure with a right anterolateral extension (modified Ravitch approach) and osteosynthesis plates accomplished stabilization of the chest wall, and contributed to weaning from mechanical ventilation.

Traumatic common hepatic artery injury causing isolated right hepatic ischemia due to a left accessory artery. A case report.

INTRODUCTION: Hepatic arterial liver flow is renowned for its redundancy. Previous studies have demonstrated that the common hepatic artery is not essential for liver survival. We present a case of a 31year-old involved in a high-speed motor vehicle accident whose liver survived thanks to the presence of an accessory hepatic artery. PRESENTATON OF THE CASE: We present the case of a 31year-old male who sustained a traumatic injury of the proper hepatic artery following a motor vehicle accident. The patient suffered temporary right liver lobe ischemia due to the presence of an accessory left hepatic artery. This resulted in the selective formation of 'biliary lakes' distinctively within the territory of the right hepatic artery supply. Simultaneously the patient developed a pseudo-aneurysm of the proper hepatic artery which required radiology intervention. At the time of pseudo-aneurysm embolisation, a rich network of arterial collaterals had formed between the accessory left hepatic and the inferior phrenic artery. On follow up the biliary lakes to the right lobe had resolved, but a small area at the periphery of the right lobe had encountered atrophy. DISCUSSION: This case report is an 'in vivo' demonstration of liver resilience to arterial flow re-distribution and demonstrates the ability of the biliary epithelium to recover from and ischemic injury. CONCLUSION: Parenchymal liver survival is mostly independent from flow within the common hepatic artery. Acute and chronic liver parenchyma changes following interruption of hepatic artery flow can still occur.

Facial firework injury: a case series.

Fireworks are used to celebrate a variety of religious, patriotic, and cultural holidays and events around the world. Fireworks are common in the United States, with the most popular holiday for their use being national Independence Day, also known as July Fourth. The use of fireworks within the context of celebrations and holidays presents the ideal environment for accidents that lead to severe and dangerous injuries. Injuries to the face from explosions present a challenging problem in terms of restoring ideal ocular, oral, and facial function. Despite the well documented prevalence of firework use and injury, there is a relatively large deficit in the literature in terms of firework injury that involves the face. We present a unique case series that includes 4 adult male patients all with severe firework injuries to the face that presented at an urban level 1 trauma center. These four patients had an average age of 26.7 years old and presented within 5 hours of each other starting on July Fourth. Two patients died from their injuries and two patients underwent reconstructive surgical management, one of which had two follow up surgeries. We explore in detail their presentation, management, and subsequent outcomes as an attempt to add to the very limited data in the field of facial firework blast injury. In addition, the coincidence of their presentation within the same 5 hours brings into question the availability of the fireworks involved, and the possibility of similar injuries related to this type of firework in the future.

Comparison of Objective Screening and Self-Report for Alcohol and Drug Use in Traumatically Injured Patients.

Alcohol and drug use is prevalent in trauma patients. Concerns over the validity of self-reporting drug use could make non laboratory screening problematic. This study sought to validate patient self-report of substance use against objective screening to determine the reliability of self-report in trauma patients. Patients admitted to either the Trauma or Burn services who were at least 18 years old were screened for alcohol and drug use with validated screening tools. Exclusion criteria were altered mental status, non English speaking, inability to answer questions for other reasons, under police custody, or admission for < 24 hours. Results from admission Blood Alcohol Concentration BAC and Urine Drug Screen UDS were also collected and compared to self-reported use to determine its reliability. Alcohol use was queried in 128 patients, 101 of whom had a BAC drawn. Of those 101, 34 (33.7%) had a BAC > 0 mg%. Alcohol Use Disorder Identification Test AUDIT screening revealed 13 (12.9%) patients who were self-reported non drinkers, none of which had a BAC > 0 mg%. Drug use was queried in 133 patients, 93 of whom had a UDS. A positive was found in 26 (28.0%) of the patients, only 12 (46.2%) of whom reported drug use in the past year. Though substance use in trauma patients is prevalent, self-report screening techniques for drugs may be inadequate at determining those patients whom could benefit from brief interventions while in the hospital. Further investigation is needed to determine the discrepancy between alcohol and drug use screening in trauma patients and more acceptable means of drug use discussion.

A clustering of injury behaviors.

BACKGROUND: Alcohol is a well-known risk factor for injury. A number of other behaviors are also associated with injury risk. We hypothesized that risky drinking would be associated with other high risk behaviors, thereby delineating a need for behavioral interventions in addition to alcohol. METHODS: A consecutive sample of trauma patients was interviewed for drinking and risky behaviors including seat belt use, helmet use, and driving behaviors. The Alcohol Use Disorders Identification Test was used to screen for risky drinking and risky behavior questions were taken from validated questionnaires. Behaviors were ranked on a Likert scale ranging from a low to a high likelihood of the behavior or assessed the frequency of behavior in the past 30 days. An Alcohol Use Disorders Identification Test score of 8 or more was considered risky drinking for adults age 21 to 64, and 4 or more for ages 16 to 20 and over 65. Risky and nonrisky drinkers were compared on behavior risk items. A p value of less than 0.05 was considered significant. RESULTS: One hundred sixty patients (mean age, 36.8 years, 72% men,) were interviewed. Risky drinkers were more likely to drive after consuming alcohol, ride with drinking drivers, tailgate, weave in and out of traffic, and make angry gestures at other drivers (all p < 0.05). Risky drinkers were less likely to wear motorcycle helmets. However, risky drinkers were no more or less likely to talk on the cell phone while driving, to use seatbelts, or use turn signals. Although number of lifetime vehicle crashes were similar, risky drinkers were more likely to have been the party at fault for the crash (mean 1.09 vs. 0.64, p = 0.03). CONCLUSIONS: Factors other than alcohol increase injury risk in problem drinkers. Injury prevention programs performing alcohol interventions should consider including behavioral interventions along with alcohol reduction strategies. New screening and intervention programs should be developed for injury behaviors that increase risk but are not alcohol related.
