Tracheobronchial rupture in a child following blunt trauma

A 6-year-old boy sustained a crush injury to the upper chest that resulted in a linear laceration of the membranous part of the lower trachea and right main stem bronchus. He presented with extensive subcutaneous emphysema, pneumomediastinum, and pneumoperitoneum. The diagnosis was indicated by a CT scan of the chest and confirmed by bronchoscopy. The trachea was intubated in the operating room after rigid bronchoscopy. Intraoperative leakage of gas from the tracheobronchial laceration was minimized by single left-lung manual ventilation and application of moist packs to the site of tracheal injury. Surgical repair was achieved with interrupted sutures of non-absorbable material; a pedicle pleural flap was used to buttress the suture line. The patient was discharged in good condition after 1 week. Complete healing of the anastomosis was attested at bronchoscopy 2 months postoperatively. The rarity of tracheobronchial lacerations in childhood is noted on review of the literature. Emphasis is placed on early recognition and expeditious management of tracheobronchial lacerations. Rarely, these lacerations have been reported to heal spontaneously.     

Bronchial rupture in children following blunt chest trauma

We present five patients with fracture of the bronchus, in whom the diagnois of bronchial rupture was first suggested because of persistent leakage of air, atelectasis of a segment of the lung or of the entire lung, mediastinal and deep cervical emphysema. In all patients the bronchoscopy was essential to confirm the diagnosis and to determine the full extent of injury.     

Isolated rupture of an accessory liver from blunt abdominal trauma in childhood

 An accessory liver is uncommonly encountered in surgical practice. It can rarely cause acute abdominal pain. An isolated injury to an accessory liver from blunt trauma in a 10-year-old boy caused major intraperitoneal haemorrhage. Laparotomy and excision of the lacerated accessory liver lobe was necessary; the patient recovered uneventfully. The literature on accessory liver is reviewed. Accepted: 18 December 2000     

CT diagnosis of gastric rupture following blunt abdominal trauma in a child

Conclusion Traumatic gastric perforations are uncommon, especially in children. CT may be helpful in establishing an early diagnosis thereby decreasing the period of peritoneal contamination, sepsis and shock. This may also lessen intraperitoneal abscess formation. This case is probably the first which illustrates the CT criteria of gastric perforation.     

Emergency department management of blunt cervical tracheal trauma in children.

A case history of a young girl who sustained a small posterior laceration of her cervical trachea after blunt trauma is presented. She was brought to the emergency department (ED) by her parents roughly two hours after the incident with only minor symptoms. While in the ED, she developed significant airway compromise over a span of minutes. Orotracheal intubation was performed to secure her airway, and she responded to conservative management of her laceration. Her signs and symptoms, resolved, and she was discharged after five days. This case illustrates the importance of urgent evaluation and careful observation of patients with possible tracheal damage, as even very small tears have the potential to cause life-threatening airway compromise.     

Isolated bowel injury in blunt abdominal trauma in childhood.

From a total of 734 children with a blunt abdominal trauma admitted to the hospital in the past 15 years, 21 patients (3%) sustained an isolated injury of the bowel (8 duodenal, 9 jejunal and 4 colon ruptures). All patients were laparotomized without a postoperative mortality. Accompanying abdominal injuries were seen only in duodenal ruptures (pancreatitis and one choledochal and pancreatic ruptures). In 85% the blunt violence was caused by bicycle accidents due to the handle bar, in one case by a car accident and in 3 children by falls. Accurate diagnosis was only possible regarding the history, the mechanism of the accident and an exact repeated clinical examination. Despite further investigations of blood chemistry laboratory findings, ultrasound and x-ray, no further confirmation of the diagnosis could be achieved. Complications, occurring in 14% of our patients, were not related to the trauma itself, but caused by a delayed diagnosis and therapy.     

Splenic abscess following blunt abdominal trauma

A rare case of splenic abscess occurring after blunt abdominal trauma in a previously healthy boy is reported. The diagnosis was made by ultrasonography. The patient recovered after splenectomy and drainage of subphrenic and intraperitoneal pus.     

Management of testicular rupture after blunt trauma in children

Purpose  

Testicular rupture is a very rare entity in children and adolescents. The aim of this study was to evaluate the outcomes of surgical repair after testicular rupture in children.     

Ureteropelvic junction disruption following blunt abdominal trauma

We report here on a case of avulsion of the ureteropelvic junction in a 7-year-old boy who was injured in a car accident. Severe brain trauma took precedence over signs and symptoms of blunt abdominal trauma, but 24 hours after the accident, progressive distension of the abdomen required further evaluation. Ultrasound examination and a computed tomography scan revealed disruption of the ureteropelvic junction. Simple primary anastomosis was performed. We discuss the characteristics of this unusual injury and include a review of the literature.     

Tracheobronchial rupture due to blunt trauma in children: report of two cases.

Tracheobronchial tree injuries occur in a small number of patients after blunt chest trauma, and their occurrence is uncommon in the pediatric trauma population. The authors report two male children, one with a tracheal rupture, and the other with disruption of the main right bronchus. Mediastinal and subcutaneous emphysema resulting in airway obstruction were noted in Case 1 and soft-tissue emphysema, pneumomediastinum and tension pneumothorax were evident in Case 2 at the time of presentation. In the child with bronchial disruption, a major airway injury was suspected early on, because of a massive air leak despite two properly placed chest tubes. The definitive diagnosis was established bronchoscopically, and thoracotomy and primary repair were performed. The child with rupture of the posterior tracheal wall was diagnosed at an early stage by bronchoscopy and he was successfully managed without surgery.     

Diaphragmatic hernia following blunt trauma in a child

Summary A nine-year old boy successfully treated for an acute diaphragmatic hernia resulting from blunt trauma is presented. The clinical features, diagnosis and management of this rare condition are briefly reviewed. From the Main Hospital, Steel Plant, Bhilai (M.P.)     

A case of mitral papillary muscle rupture due to blunt chest trauma

Mitral regurgitation due to papillary muscle rupture after blunt chest trauma is uncommon. Sudden onset severe mitral regurgitation may lead to death due to heart failure if surgical repair is delayed. A previously healthy 12-year-old girl underwent splenectomy and chest tube insertion for pneumothorax after a traffic accident in a vehicle 15 days before. She was discharged from the hospital after a nine-day follow-up. She was presented to our hospital due to respiratory distress. On physical examination, an apical holosystolic murmur radiating to the axillary region was recognized. Transthoracic echocardiogram showed severe mitral regurgitation with freely moving posterior mitral chordae and prolapse of the posterior mitral valve leaflet. She received reimplantation of the complete ruptured posteromedial papillary muscle of the mitral valve. Her medical condition improved after the operation. On the postoperative echocardiogram, the left ventricular systolic function was normal with no mitral regurgitation.     

Significance of periportal low-attenuation zones following blunt trauma in children

The CT scans of 400 consecutive children evaluated with CT following blunt abdominal trauma were evaluated to determine the frequency of periportal lowattenuation zones, assess patterns of associated intraabdominal injury, and examine clinical outcome. Periportal low-attenuation zones were noted in 60 children (15%). The presence of these zones was associated with a significantly higher incidence of intraabdominal injury (60% versus 11%,p=0.0001). Injuries most frequently associated with zones of periportal low-attenuation included hepatic (n=23,38%), and adrenal (n=14,23%). Children who had periportal low-attenuation zones tended to be more physiologically unstable as evidenced by a lower Trauma Score (diffuse, 11.9; focal, 13.4) than children without the zones (15.1,p=0.0001). The presence of these zones was also associated with a significantly higher mortality rate (13% versus 1%,p=0.0001). Ten children who had periportal low-attenuation zones and no hepatic injury on CT had a normal appearing liver on gross inspection at surgery or autopsy. In conclusion, periportal lowattenuation zones are common in children who have hepatic injury. These zones may be seen in conjunction with non-hepatic visceral injury or in the absence of intraabdominal injury. The presence of zones of periportal lowattenuation is associated with a higher index of physiologic instability, and higher mortality.     

Management of blunt tracheal trauma in children: a case series and review of the literature

Blunt tracheal trauma seldom develops in children because of their anatomy and the mobility of the cartilage. It has the potential to be overlooked, either because of the severity of concomitant injuries or because of the unfamiliarity of paediatricians with this type of injury. However, tracheal injury might be lethal due to airway compromise. Early bronchoscopy may be necessary to anticipate complications and prevent permanent dysfunction. We present a retrospective, double-institution case series over a 5-year period, describing five children, aged 3 to 14 years, with tracheal injury after blunt cervical trauma. All patients showed emphysema with pneumomediastinum. After explorative bronchoscopy, all patients were successfully treated with antibiotics and/or supportive ventilation. In summary, minimal lesions due to blunt tracheal trauma could be treated conservatively in children. Since the external signs of tracheal injury are not indicative of the extent of the trauma, a high index of suspicion is warranted in these patients.     

Transient electrocardiographic abnormalities following blunt chest trauma in a child

Blunt cardiac injury may occur in patients after suffering nonpenetrating trauma of the chest. It encompasses a wide spectrum of cardiac injury with varied severity and clinical presentation. Electrocardiographic abnormalities are frequently encountered. This article presents a case of a child who presented with complete right bundle branch block on the initial ECG at the emergency department. She suffered blunt chest trauma during a horseback riding accident. She was admitted for cardiac monitoring. The electrocardiographic abnormalities resolved within 12 hours. No signs of myocardial injury were found on repeat serum troponin measurement and echocardiography. The natural history of ECG abnormalities in the pediatric age group following blunt chest trauma is limited. Although a complete right bundle branch block may be transient in adult patients, this has not been previously reported in a children. Significant ECG abnormalities can be encountered in children following blunt chest trauma. Although a complete RBBB can be associated with severe injury to the RV, it can also occur with minor injury.     

Evisceration through multiple abdominal wall defects following blunt abdominal injury

We report an unusual case of a posttraumatic evisceration of small and large bowel through 2 holes in the anterior abdominal wall after a motor vehicle accident. Prompt adequate management consists of reestablishing the perfusion of the eviscerated organ if the blood supply is compromised, performing a full laparotomy to exclude intra-abdominal organ injury and meticulous cleaning of the eviscerated organs before reducing them in the abdomen and closing the abdomen in layers.
