Management of Renal Artery-Inferior Vena Cava Fistula Following Nephrectomy for Penetrating Trauma

Background: Renal artery to inferior vena cava fistula is a rare event postnephrectomy. We report a case of an adult male in whom a renal artery to inferior vena cava fistula was detected on non-invasive studies following nephrectomy for penetrating trauma. Case Report: A fistula between the right renal artery and inferior vena cava was confirmed with diagnostic angiography. The fistula was successfully embolized using microcoils. Discussion: This case highlights the importance of exploring retroperitoneal hematomas secondary to penetrating trauma.

Multiple Trauma in Pregnant Women: Injury Assessment, Fetal Radiation Exposure and Mortality. A Multicentre Observational Study.

Purpose: Fetal radiation exposure in pregnant women with trauma is a concern. The purpose of this study was to evaluate fetal radiation exposure with regard to the type of injury assessment performed.Methods: It is a multicentre observational study. The cohort study included all pregnant women suspected of severe traumatic injury in the participating centres of a national trauma research network. The primary outcome was the cumulative radiation dose (mGy) received by the fetus with respect to the type of injury assessment initiated by the physician in charge of the pregnant patient. Secondary outcomes were maternal and fetal morbi-mortality, the incidence of haemorrhagic shock and the physicians’ imaging assessment with consideration of their medical specialty.Results: Fifty-four pregnant women were admitted for potential major trauma between September 2011 and December 2019 in the 21 participating centres. The median gestational age was 22 weeks [12-30]. Seventy-eight percent of women (n=42) underwent WBCT. The remaining patients underwent radiographs, ultrasound or selective CT scans based on clinical examination. The median fetal radiation doses were 38 mGy [23-63] and 0 mGy [0-1]. Maternal mortality (5.6%) was lower than fetal mortality (16.7%). Two women (out of 3 maternal deaths) and 7 fetuses (out of 9 fetal deaths) died within the first 24 hours following trauma.Conclusion: Immediate WBCT for initial injury assessment in pregnant women with trauma was associated with a fetal radiation dose below the 100 mGy threshold. Among the selected population with either a stable status with a moderate and nonthreatening injury pattern or isolated penetrating trauma, a selective strategy seemed safe.

How Did the COVID-19 Pandemic Affect Trauma Volume at an Urban Level I Trauma Center?

Introduction The COVID-19 pandemic changed the face of health care worldwide. While the impacts from this catastrophe are still being measured, it is important to understand how this pandemic impacted existing health care systems. As such, the objective of this study was to quantify its effects on trauma volume at an urban Level 1 trauma center in one of the earliest and most significantly affected US cities. Methods A retrospective chart review of consecutive trauma patients admitted to a Level 1 trauma center from January 1, 2017 to December 31, 2020 was completed. The total trauma volume in the years prior to the pandemic (2017-2019) was compared to the volume in 2020. These data were then further stratified to compare quarterly volume across all 4 years. Results A total of 4138 trauma patients were treated in the emergency room throughout 2020 with 4124 seen during 2019, 3774 during 2018, and 3505 during 2017 in the pre-COVID-19 time period. No significant difference in the volume of minor trauma or trauma transfers was observed ( P < .05). However, there was a significant increase in the number of major traumas in 2020 as compared to prior years (38.5% vs 35.6%, P < .01) and in the volume of penetrating trauma (29.1% vs 24.0%, P < .01). Discussion During the COVID-19 outbreak, trauma remained a significant health care concern. This study found an increase in volume of penetrating trauma, specifically gunshot wounds throughout 2020. It remains important to continue to devote resources to trauma patients during the ongoing COVID-19 pandemic.

Corneal Trauma

Trauma is often the main cause of unilateral loss of vision in developing countries. Although corneal trauma can range from tiny corneal abrasions to sight-threatening and penetrating ocular injuries, even minor corneal trauma that breaches the epithelium has the potential to result in microbial keratitis and its associated complications, up until complete loss of vision. Even though ocular trauma is a global problem, blindness from eye injuries occurs mostly in developing countries, especially those where wars and civil conflicts bring around eye traumas from various weapons such as land mines, chemical substances, etc. Chemical injuries from both acids and alkalies are common causes of corneal injury due to their easy availability and soft regulations regarding their use. This chapter includes photos of trauma cases of the anterior segment, corneal and conjunctival foreign bodies, sequelae of blunt and penetrating trauma, chemical injuries, as well as a case of posttraumatic iris cyst.

Bullet Embolism into the Common Iliac Artery from a Gunshot Wound to the Heart

We describe the management of bullet embolism from a penetrating cardiac injury, including the clinical, radiographic, and operative considerations in this challenging trauma scenario. Bullet embolism represents a rare but complex subset of ballistic penetrating trauma, and highlights the importance of radiographic correlation with intraoperative findings.

Alcohol is not associated with increased mortality in adolescent traumatic brain injury patients

Purpose Compared to adults, there is a paucity of data regarding the association of a positive alcohol screen (PAS) and outcomes in adolescent patients with traumatic brain injury (TBI). We hypothesize adolescent TBI patients with a PAS on admission to have increased mortality compared to patients with a negative alcohol screen. Methods The 2017 Trauma Quality Improvement Program database was queried for patients aged 13–17 years presenting with a TBI and serum alcohol screen. Patients with missing information regarding midline shift on imaging and Glasgow Coma Scale (GCS) score were excluded. A multivariable logistic regression analysis for mortality was performed. Results From 2553 adolescent TBI patients with an alcohol screen, 220 (8.6%) had a PAS. Median injury severity scores and rates of penetrating trauma (all p > 0.05) were similar between alcohol positive and negative patients. Patients with a PAS had a similar mortality rate (13.2% vs. 12.1%, p = 0.64) compared to patients with a negative screen. Multivariate logistic regression controlling for risk factors associated with mortality revealed a PAS to confer a similar risk of mortality compared to alcohol negative patients (p = 0.40). Conclusion Adolescent TBI patients with a PAS had similar associated risk of mortality compared to patients with a negative alcohol screen.

Neurointerventional management of cerebrovascular trauma

Traumatic cerebrovascular injuries following blunt or penetrating trauma are common and carry a high risk of permanent disability or death. Proper screening, diagnosis, and treatment of these lesions is essential to improve patient outcomes. Advances in imaging continue to improve the accuracy of non-invasive diagnosis of these injuries while new clinical data provide better evidence for optimal management, whether medical or invasive. Here, we review screening, diagnosis, and treatment of traumatic cerebrovascular injuries.

Complications in Patients with Cardiac Penetrating Trauma

Background: Cardiac penetrating trauma is a medical emergency that mostly affects young people. Based on the type of injury and associated complications, it can present as a surgical challenge and can lead to mortality. Objective: The aim of this study is to evaluate the complications of penetrating heart trauma among patients referred to Shahid Madani Hospital. Methods: In this retrospective descriptive study, the data of penetrating cardiac trauma patients referred to Shahid Madani hospital, Karaj, Tehran, from 2016-2019, were investigated. Information, including age, sex, cause of trauma, traumatized area and complications, was extracted and recorded in a data collection form. The data were evaluated statistically using SPSS v18. Results: A total of 44 patients were included in the study, where the mean age of the patients was 25 years. 73.3% of these patients were men and 26.7% were women. Knife stab wounds were the most prevalent cause of the trauma, present in 93.3% of patients. 73.3% of the patients had cardiac tamponade and 20% had a pneumothorax. The right ventricle was the most common site of the injury in 46.7% of the patients. A mortality rate of 3.4% was reported in this study. Conclusion: The results of this study showed that the highest penetrating heart rate trauma occurred among young people, and the most common cause of the trauma was a knife stab. The most common area of the injury was the right ventricular, and cardiac tamponade was the most common complication.

A rare case: Penetrating craneoencefalic trauma by knife

Background: Cranioencephalic penetrating trauma (CPT) is caused by a sharp or short- pointed object that passes through the bone, dura mater, brain and other structures. Its incidence is unknown and few cases are described; penetrating injuries represent 0.4%, therefore there is no protocolized management. Case report: A 24-year-old male patient suffered penetrating trauma at left parietal region with a "knife"; he was sutured and sent home with analgesics. Five days after the trauma, he was admitted for headache, disorientation and decreased visual acuity. X-ray (XR) of Cranium evidencing a foreign body, therefore it is sent to a reference hospital. Evolution: The diagnosis is confirmed by a computerized tomography (CT) scan of the skull with 3-dimensional reconstruction (3D) plus CT angiography (angio CT), which shows "knife" in the left parietal region without vascular compromise. Neurosurgeons perform removal of the foreign body plus a dura mater plasty. Patient stay 12 days hospitalized with a favorable evolution and improvement of neurological symptomatology. Conclusion: CPT due to a knife is an emergency and there is no protocolized management. The removal of the foreign body must be done in a hospital for the risk of lesions of large vessels.
