Severity of traumatic adrenal injury does not meaningfully affect clinical outcomes.

PURPOSE: There are limited data comparing the severity of traumatic adrenal injury (TAI) and the need for interventions, such as transfusions, hospitalization, or incidence of adrenal insufficiency (AI) and other clinical outcomes. The aim of this study was to analyze the relationship between the grade of TAI and the need for subsequent intervention and clinical outcomes following the injury. METHODS: After obtaining Institutional Review Board approval, our trauma registry was queried for patients with TAI between 2009 and 2017. Contrast-enhanced computed tomography (CT) examinations of the abdomen and pelvis were evaluated by a board-certified radiologist with subspecialty expertise in abdominal and trauma imaging, and adrenal injuries were classified as either low grade (American Association for the Surgery of Trauma (AAST) grade I-III) or high grade (AAST grade IV-V). Patients without initial contrast-enhanced CT imaging and those with indeterminate imaging findings on initial CT were excluded. RESULTS: A total of 129 patients with 149 TAI were included. Eight-six patients demonstrated low-grade injuries and 43 high grade. Age, gender, and Injury Severity Score (ISS) were not statistically different between the groups. There was an increased number of major vascular injuries in the low-grade vs. high-grade group (23% vs. 5%, p < 0.01). No patient required transfusions or laparotomy for control of adrenal hemorrhage. There was no statistical difference in hospital length of stay (LOS), ventilator days, or mortality. Low-grade adrenal injuries were, however, associated with shorter ICU LOS (10 days vs. 16 days, p = 0.03). CONCLUSION: The need for interventions and clinical outcomes between the low-grade and high-grade groups was similar. These results suggest that, regardless of the TAI grade, treatment should be based on a holistic clinical assessment and less focused on specific interventions directed at addressing the adrenal injury.

Five-Year Management of Vascular Injuries of the Extremities in the "Real-World" Setting in Northeastern Greece: The Role of Iatrogenic Traumas.

BACKGROUND: Vascular trauma comprises a diagnostic and surgical challenge. Aim of this study was to present the vascular traumas treated in our Tertiary Hospital during the last 5 years. METHODS: We retrospectively reviewed the surgical records of our vascular department and documented the site and type of vascular injuries of the extremities along with the concurrence of musculoskeletal injuries. The type and outcome of surgical interventions were also recorded. RESULTS: Fifty-eight cases of vascular trauma were recorded (39 in the upper and 19 in the lower extremities). Overall, iatrogenic traumas accounted for 41.3% of cases. The arterial injuries of the upper limb were blunt and penetrating in 27% and 67%, respectively. The most affected artery in the upper limb was the radial artery (37.8%), followed by the ulnar artery (27%) and the brachial artery (24.3%). Orthopedic injuries were recorded in 19% of patients. Management involved simple revascularization, bypass operations, patch arterioplasty and endovascular management in 48.7%, 33.3%, 5.1%, and 5.1%, respectively. The most affected site in the lower extremity was the common femoral artery (36.8%) followed by the popliteal artery (21%). Bone fractures were reported in 5 cases (26.3%). The surgical management involved bypass, simple revascularization, patch arterioplasty in 42.1%, 26.3%, and 21%, respectively. Endovascular management was performed in 10.5%. CONCLUSIONS: A considerable percentage of iatrogenic vascular injuries was recorded, affecting both the upper and lower limbs. Despite the trend toward centralization of vascular services, a basic service of vascular surgery should be available in most sites to ensure that patients with vascular injuries receive fast and appropriate care.

Quantifying the burden of trauma imaging on the CT scan service at a major trauma centre in South Africa.

BACKGROUND: Imaging is an integral part of trauma management and the huge burden of trauma in South Africa places substantial pressures on radiology resources. This study aims to provide a holistic overview of the burden of trauma imaging and the cost of trauma to a busy CT scanning facility at a tertiary hospital in South Africa. METHOD: We set out to describe and quantify the impact of blunt poly-trauma on CT scanning services at Grey's Hospital in Pietermaritzburg. We aimed to provide a holistic assessment in terms of use of equipment and staff, cost to the hospital and overall usage of CT scanning. RESULTS: Over the four-year study period, 1572 patients required a CT scan following blunt torso trauma (mean age: 30 years, 81% males). Of the 1572 patients, 625 had a chest radiograph (40%), 383 a cervical spine X-ray (24%), 347 a pelvic X-ray (22%), 292 a skull X-ray (18%), 193 a limb X-ray (12%), 133 an abdominal radiograph (8%), and 86 a FAST scan (5%). The 1572 CT included: 967 head, 568 neck, 65 chest, 241 abdominal, 228 pelvic, 12 upper limb, 38 lower limb and 394 had full body (Pan) CT scan. The mean total cost of the CT scanning for blunt poly-trauma is ZAR 12 000. The total cost of CT scanning for blunt poly-trauma is 0.92% of the total hospital expenditure. Roughly 7.8% of the total hours worked by the CT scanner over the time period under review was dedicated to blunt poly-trauma. CONCLUSION: Blunt poly-trauma is a preventable disease, which has a major financial impact on the healthcare system in general. This study has documented the tremendous burden it places on an already stretched CT scanning service.

"Mixed" trauma to the carotid artery in a mixed martial arts injury - A case report and review of the literature.

We present the case of a mixed martial arts (MMA) cage fighter who presented to the emergency department with a right sided common carotid artery pseudoaneurysm as a result of a neck trauma at an MMA event. We discuss the management of blunt force neck trauma, differential diagnosis, imaging findings and review the literature on blunt cerebrovascular injury following blunt force injury to the neck.

Hemobilia: An Uncommon But Notable Cause of Upper Gastrointestinal Bleeding.

GOAL AND BACKGROUND: A literature review to improve practitioners' knowledge and performance concerning the epidemiology, diagnosis, and management of hemobilia. STUDY: A search of Pubmed, Google Scholar, and Medline was conducted using the keyword hemobilia and relevant articles were reviewed and analyzed. The findings pertaining to hemobilia etiology, investigation, and management techniques were considered and organized by clinicians practiced in hemobilia. RESULTS: The majority of current hemobilia cases have an iatrogenic cause from either bile duct or liver manipulation. Blunt trauma is also a significant cause of hemobilia. The classic triad presentation of right upper quadrant pain, jaundice, and upper gastrointestinal bleeding is rarely seen. Computed tomography and magnetic resonance imaging are the preferred diagnostic modalities, and the preferred therapeutic management includes interventional radiology and endoscopic retrograde cholangiopancreatography. Surgery is rarely a therapeutic option. CONCLUSIONS: With advances in computed tomography and magnetic resonance imaging technology, diagnosis with these less invasive investigations are the favored option. However, traditional catheter angiography is still the gold standard. The management of significant hemobilia is still centered on arterial embolization, but arterial and biliary stents have become accepted alternative therapies.

[Coronary artery dissection following blunt chest trauma]. / Koronararteriedissektion er en sjælden komplikationi forbindelse med et stumpt thoraxtraume

A previously healthy 38-year-old man was admitted to hospital with chest pain. The day before the patient had been to a karate session and had received multiple punches and kicks to the chest region. An ECG showed Q-waves in V1 and V2 and flattening of the T-waves in V1-V6. Levels of cardiac enzyme markers were elevated. The patient subsequently underwent coronary angiography with supplemental optical coherence tomography that revealed a bifurcate dissection involving the proximal parts of left ramus interventricularis anterior and circumflex coronary artery. Two drug-eluting stents were implanted with good angiographic result.

CT with coronal reconstruction identifies previously missed smaller diaphragmatic injuries after blunt trauma.

Diaphragmatic injuries (DIs) are difficult to diagnose and often go unrecognized after blunt trauma. We proposed that CT scan with coronal reconstruction (CTCR) improves the detection of small DIs missed by chest x-ray (CXR) and CT scan with axial views (CTAX). We performed a retrospective review at a Level I trauma center from 2001 to 2006 and identified 35 patients who underwent operative repair of DI after blunt trauma. The size of the DI and the radiographic test (CXR, CTAX, and CTCR) that identified the defect was compared. Results were analyzed using mean, Mann-Whitney U test, and Fisher exact test. Of the 35 DI repairs, nine were performed after CXR alone and 12 after identification by both a CXR and CTAX. There was no significant difference between the mean DI size identified by CXR with and without CTAX (10.6 vs 9.7, P = 0.88). The remaining 14 DIs were undetected by CXR and CTAX. Seven of these (before CTCR) were found during exploratory laparotomy and seven were identified by CTCR (4.6 cm vs 3.5 cm, P = 0.33). The mean DI size identified by CTCR was significantly smaller than that identified by CXR alone (4.6 cm vs 9.7 cm, P < 0.05) and by CXR and CTAX (4.6 cm vs 10.6 cm, P < 0.0005). CTCR improves the ability to detect smaller DI defects (4 to 8 cm) that were previously missed by CXR and CTAX. CTAX adds little to CXR alone for the diagnosis of large defects (greater than 8 cm).

Jujitsu kick to the abdomen: a case of blunt abdominal trauma resulting in hematochezia and transient ischemic colitis.

Blunt abdominal trauma is a common presentation to the emergency department. Ischemic colitis is a rare complication of this and its possible sequelae are important for an emergency physician to recognize. A 21-year-old man presented to the emergency department with abdominal pain and hourly episodes of bright red blood per rectum shortly after being kicked in the stomach at his jujitsu class. He had no significant medical history, and results of his systems review were otherwise unremarkable. On examination, he appeared well, with normal vital signs. He had mild lower abdominal tenderness, but there were no peritoneal signs present. There was blood on the digital rectal examination. His hemoglobin, platelet, and international normalized ratio levels were normal and his abdominal radiograph was unremarkable. The gastroenterology service was contacted because of the hematochezia and a flexible sigmoidoscopy was performed. The sigmoidoscopy showed erythema, ulceration, and edema of a segment in the left colon, consistent with ischemic colitis. This was later confirmed on biopsy. A computed tomography (CT) scan of the abdomen was conducted, which revealed left colonic inflammation consistent with colonic ischemia. There was no mesenteric vascular thrombosis or mesenteric hematoma found on CT. His hematochezia and abdominal pain subsided spontaneously, and he was discharged home. This case illustrates transient ischemic colitis as a potential presentation of blunt abdominal trauma, and emergency physicians should consider this uncommon diagnosis in the differential diagnosis of patients presenting after abdominal trauma.

Contrast-enhanced ultrasound for blunt hepatic trauma: an animal experiment.

OBJECTIVE: The aim of this study was to study the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of active hemorrhage and intraparenchymal lesions in blunt hepatic trauma versus conventional ultrasound (US). METHODS: Twenty heparinized and anesthetized domestic pigs have been created to animal models with blunt hepatic trauma by a special impacting device. Conventional US and CEUS were performed to determine if hepatic traumas were present. RESULTS: Active hemorrhage, the presence of intraparenchymal lesions, and sonographic pattern were evaluated for conventional US and CEUS, as compared with laparotomy and pathologic findings. Contrast-enhanced US detected active hemorrhage from the injured livers in all cases, but conventional US did not find that in any case. The sensitivity of CEUS and conventional US in diagnosing intraparenchymal lesions of blunt hepatic trauma were 100% and 60%, respectively. CONCLUSIONS: Contrast-enhanced US is more sensitive than conventional US in determining the active hemorrhage and intraparenchymal lesions in blunt hepatic trauma.

[Arterial air embolism following multiple injuries after a fall from the tenth floor]. / Arterielle Luftembolie nach Polytraumatisierung bei Sturz aus dem 10. Stock.

We report about the case of a 20-year-old patient who fell from the tenth floor. The patient suffered multiple injuries and systemic gas embolism. He survived his injuries despite CPR, massive transfusion, development of ARDS and SIRS with minimal neurological deficit. The possible pathogenesis of the systemic gas embolism as well as the therapy are discussed. Besides stabilizing the circulation with i.v. fluids, blood transfusion and catecholamine therapy, the use of hyperbaric oxygenation was the decisive therapeutic measure.

Trauma-induced changes in diaphyseal cross-sectional geometry in two elites from Copan, Honduras.

This research utilized biplanar radiographs to estimate cross-sectional biomechanical properties for the skeletal remains of two elite individuals from the Early Classic period (ca. AD 400-600) of Copan, Honduras: K'inich Yax K'uk' Mo' (Hunal Burial 95-2), founder of the Early Classic Dynasty at Copan, and the primary female interment (Burial 37-8) from the Motmot tomb. Both individuals survived severe blunt-force insults to the right forearm. Gross skeletal examination and evaluation of the radiographs for K'inich Yax K'uk' Mo' suggest that these traumas resulted from, at least in part, disuse atrophy of the affected forearm skeletal elements. Gross and radiologic evaluation of the Motmot remains countered the possibility that she suffered from a metabolic bone disease, and confirmed the presence of a well-healed parry fracture of the right ulna. The degree of asymmetry in cross-sectional biomechanical properties reported here for K'inich Yax K'uk' Mo' is likely the secondary result of the described blunt-force trauma. The results obtained for the principal Motmot interment are not as dramatic, but suggest subtle changes to humeral cross-sectional geometry subsequent to trauma.

[Radiofrequency coagulation for splenic resection--a case report]. / Die Radiofrequenz-Koagulation bei der nicht-anatomischen Resektion der Mil--Ein Fallbericht.

Radiofrequency ablation is used in our Department of Surgery in cases of unresectable liver tumors. The case of a 22-year old male, who underwent nonanatomical resection of the spleen for trauma, is briefly reported. Splenic resection with the use of the radiofrequency needle could be performed safely and easily without complications. We use radiofrequency coagulation routinely in cases of blunt trauma of the spleen and liver.

Favorable outcome in a large left heart air embolism: lessons from an unusual complication of a noninvasive chest scan.

OBJECTIVE: To report an unusual life-threatening complication of the performance of a computed tomographic (CT) scan of the chest. DESIGN: Case report. SETTING: University hospital. PATIENT: An intubated patient with blunt thoracic trauma. INTERVENTION: Performance of a CT scan of the chest at full inspiration. MAIN RESULT: With air insufflation, a large left ventricular air embolism occurred as a consequence of an airway breach, revealed by the simultaneous existence of a mild bilateral anterior pneumothorax. CONCLUSION: CT scan of the chest in patients at risk of airway breach (patients with acute respiratory distress syndrome, trauma patients) should first be performed at full expiration, not full inspiration.

Emergency endovascular treatment of a life-threatening hemorrhage from traumatic rupture of the left extracranial vertebral artery.

Hemorrhagic complications from transection of cervical arteries in blunt traumas are rare. We report a case of potentially fatal hemorrhage from rupture of the left vertebral artery in a closed trauma, successfully treated by endovascular injection of glue. Endovascular embolization may be considered as an alternative to surgical exploration in the treatment of traumatic lesions of vertebral arteries.

Laparoscopic examination of the traumatized spleen with blood salvage for autotransfusion.

The management of splenic trauma presents a dilemma to the surgeon, who must weigh the risks of operative versus nonoperative management. Laparoscopy has been used increasingly for trauma cases to decrease the morbidity associated with standard laparotomy. Autotransfusion of the patient's shed blood has also become widespread to decrease the risks associated with transfusion. We describe the case of a 15-year-old male with blunt splenic trauma, in which laparoscopy was used to examine the spleen to ascertain the need for operative treatment, to look for other intra-abdominal injuries, and to salvage intraperitoneal blood for autotransfusion. In this case, laparoscopy determined that laparotomy would be nontherapeutic, and that autotransfusion could obviate the need for banked-blood transfusion.

Stroke without dissection from a neck holding manoeuvre in martial arts.

Carotid artery trauma is a known cause of stroke in young people. The vessel may occlude, dissect or shower thrombotic emboli into intracranial vessels. This paper reports the use of single photon emission computed tomography (SPECT) imaging in a 29 year old man who developed an embolic stroke after neck holding manoeuvres at a martial arts class. Awareness of the potential consequences of these procedures is matched by the need for rapid and accurate diagnosis of stroke now that thrombolytic and neuroprotective treatments are emerging, which are effective only within a short time window.

Sigmoid colon obstruction due to blunt abdominal trauma: a case report.

Post-traumatic colonic stenosis (obstruction) is rare. We experienced a case of sigmoid obstruction due to blunt abdominal trauma. A 75-year-old man was hit on the lower abdomen 3 days before admission and gradually developed abdominal pain and distension. Laboratory data showed severe inflammation and a barium enema disclosed obstruction of the sigmoid colon. Conservative treatment was carefully carried out, because there was no sign of peritoneal irritation and there were passages of normal stool and flatus. The sigmoid obstruction gradually improved and the stenosis was almost undetectable on a barium enema on the 51st hospital day. An abdominal contusion is the most likely causal factor in this case. Compression of the sigmoid colon between the abdominal wall and the promontory of the pelvis is the most possible explanation.

[Encephaloangioscintigraphy in the diagnosis of posttraumatic cerebral venous circulatory disorders]. / Entsefaloangiostsintigrafiia v diagnostike posttravmaticheskikh tserebral'nykh venoznykh distsirkuliatsii.

Encephaloangioscintigraphy performed in 30 patients with a closed craniocerebral trauma has shown simultaneous inhibition of the venous cerebral blood flow both in the vascular regions of the cerebral hemispheres and in the lateral sinuses indicating the common pathogenesis of disorders of the venous circulation in these parts of the circulatory bed. The most informative characteristic feature of the venous outflow is a period of RP half-life, determined on a radiocirculogram of the brain. The diagnostic efficacy of the above method in the detection of disorders of the venous circulation of the brain in some vascular regions provides an opportunity for a purpose-oriented use of adequate methods of reflexotherapy.
