Objective. This study is aimed at investigating the early diagnosis and efficacy of emergency treatments of nine patients with severe multiple injuries accompanied by traumatic aortic dissection (TAD). Methods. Patients who sustained severe multiple injuries accompanied by TAD following a car accident ( n = 6 ) and falls from a height ( n = 3 ) were treated in the emergency department of our hospital from October 2017 to July 2021. Data of these patients, including seven men and two women (average age,  53 ± 15.2 years; range, 18–83 years) were analysed retrospectively. Upon hospital arrival, the multidisciplinary treatment (MDT) trauma team, composed of doctors and nurses, immediately performed resuscitation following the Green Channel Consultation and Treatment Process for Severe Multiple Injuries. Life-threatening injuries were managed urgently. Blood tests and blood preparation and bedside B-scan ultrasonography and CT were performed. Aortic computed tomography angiography (CTA) was conducted decisively in patients suspected of TAD so that endovascular graft exclusion (EVGE) with the aortic covered stent can be performed promptly, followed by emergency management, second-stage surgery, and intensive care according to the injury control strategy. Results. This study included nine patients suffering from severe multiple injuries accompanied by Stanford type B TAD, with injury severity scores ranging from 35 to 43 points. Six patients underwent EVGE while receiving emergency treatment, whereas two patients who also had intracranial haemorrhage underwent selective EVGE. One case of TAD missed in the emergency department was detected 13 days after hospitalisation; therefore, the patient promptly underwent EVGE. Emergency procedures performed included exploratory laparotomy and splenectomy ( n = 2 ), thoracic closed drainage ( n = 5 ), haemothoracotomy ( n = 3 ), second-stage fracture surgery ( n = 4 ), and tracheotomy ( n = 1 ). Postinjury complications included haemorrhagic shock, coagulation disorders, hyoxaemia, pulmonary infection, renal insufficiency, and hypoproteinaemia; however, all patients recovered after intensive care treatment. Aortic CTA after EVGE revealed the disappearance of the dissection and the resorption of the intermural haematoma. However, varying degrees of stenosis or occlusion were observed in the left subclavian artery. Nine patients with severe multiple injuries were treated satisfactorily by the MDT, without fatalities, and all patients were discharged for rehabilitation. Conclusion. In this study, procedures including resuscitation, urgent aortic CTA for definitive diagnosis, prompt EVGE, emergency injury control surgery, second-stage definitive surgery, intensive care treatment, and rehabilitation were rationally performed by the emergency MDT trauma team. Overall, this continuous and seamless process is a key factor for the successful treatment of patients with severe multiple injuries accompanied by TAD.
