Current updates in acute traumatic aortic injury: radiologic diagnosis and management

Acute traumatic aortic injuries, which have substantial lethal outcomes at the time of admission, are fatal in 80% to 90% of cases. These injuries are relatively rare and have nonspecific clinical presentations. Radiologists and emergency physicians need to identify the radiological signs of acute traumatic aortic injury and differentiate them from common imaging errors to ensure accurate diagnosis and determine appropriate management protocols. In combination with image-guided interventions, advances in cross-sectional imaging have enabled nonsurgical management of acute traumatic aortic injuries. Timely and precise diagnoses of these injuries following prompt treatment are essential as up to 90% of patients presenting at the hospital can undergo early repair.

Clinical characteristics and management of patients with fat embolism syndrome in level I Apex Trauma Centre / 中华创伤杂志(英文版)

PURPOSE@#Fat embolism syndrome (FES) is systemic manifestation of fat emboli in the circulation seen mostly after long bone fractures. FES is considered a lethal complication of trauma. There are various case reports and series describing FES. Here we describe the clinical characteristics, management in ICU and outcome of these patients in level I trauma center in a span of 6 months.@*METHODS@#In this prospective study, analysis of all the patients with FES admitted in our polytrauma intensive care unit (ICU) of level I trauma center over a period of 6 months (from August 2017 to January 2018) was done. Demographic data, clinical features, management in ICU and outcome were analyzed.@*RESULTS@#We admitted 10 cases of FES. The mean age of patients was 31.2 years. The mean duration from time of injury to onset of symptoms was 56 h. All patients presented with hypoxemia and petechiae but central nervous system symptoms were present in 70% of patients. The mean duration of mechanical ventilation was 11.7 days and the mean length of ICU stay was 14.7 days. There was excellent recovery among patients with no neurological deficit.@*CONCLUSION@#FES is considered a lethal complication of trauma but timely management can result in favorable outcome. FES can occur even after fixation of the fracture. Hypoxia is the most common and earliest feature of FES followed by CNS manifestations. Any patient presenting with such symptoms should raise the suspicion of FES and mandate early ICU referral.

Innocuous cardiac gunshot that proved fatal: A bitter lesson learned / 中华创伤杂志(英文版)

The management of hemodynamically normal patients with retained intra-pericardial foreign body remains a matter of conjecture. The available literature supports non-operative management of such innocuous foreign bodies. We report our experience of a hemodynamically normal patient with a retained intra-pericardial pellet from a firearm injury. He initially received successful non-operative management but developed fatal hemopericardium 21 days after injury. In this paper, we discussed the pitfalls in the management of such injuries in light of the available literature and summarized the clinical experience.

Blunt traumatic superior gluteal artery pseudoaneurysm presenting as gluteal hematoma without bony injury: A rare case report / 中华创伤杂志(英文版)

Blunt traumatic injuries to the superior gluteal artery are rare in clinic. A majority of injuries present as aneurysms following penetrating trauma, fracture pelvis or posterior dislocation of the hip joint. We reported a rare case of superior gluteal artery pseudoaneurysm following blunt trauma presenting as large expanding right gluteal hematoma without any bony injury. The gluteal hematoma was suspected clinically, confirmed by ultrasound and the arterial injury was diagnosed by CT angiography that revealed a large right gluteal hematoma with a focal contrast leakage forming a pseudoaneurysm within the hematoma. Pseudoaneurysm arose from the superior gluteal branch of right internal iliac artery, which was successfully angioembolized. The patient was discharged on day 4 of hospitalization with resolving gluteal hematoma. This report highlighted the importance of considering an arterial injury following blunt trauma to the buttocks with subsequent painful swelling. Acknowledgment of this rare injury pattern was necessary to facilitate rapid diagnosis and appropriate treatment.

Acute femoral artery pseudoaneurysm due to lesser trochanter fragment: an unusual complication of an intertrochanteric fracture / 中华创伤杂志(英文版)

False aneurysm of the femoral artery is a rare complication of intertrochanteric fracture. Most of these situations are due to iatrogenic trauma or the trauma itself and are rarely caused by dislocated bone fragments. Here we report a case of a 72-year-old man who presented acutely with a pseudoaneurysm of the superficial femoral artery from the spike of a lesser trochanter fragment. Percutaneous endovascular treatment of the pseudoaneurysm with a covered stent was undertaken on an urgent basis. Five days later, the patient was operated upon and the lesser trochanter fragment was excised through an anterior incision and the intertrochanteric fracture was fixed using dynamic hip screws. The fracture was united at 10 weeks. At one-year's follow-up, there were no graft-related complications. This case illustrates that an intertrochanteric fracture with a displaced lesser trochanter fragment can present acutely with bleeding and a pseudoaneurysm of the femoral artery.

Cerebral fat embolism: a diagnostic challenge

Fat embolism syndrome [FES] is a rare but a serious clinical catastrophe occurring after traumatic injury to long bones. Cerebral involvement in the absence of pulmonary or dermatological manifestation on initial presentation may delay the diagnosis of cerebral fat embolism [CFE]. We discuss a case series of CFE which posed a challenge in diagnosis. The clinical presentations of these patients did not satisfy the commonly used clinical criteria for aiding the diagnosis of FES. Early MRI brain [DWI and T2 weighted sequences] in patients with neurological symptoms after trauma even in the absence of pulmonary and dermatological findings should be the goal
