          Abstract

          Background

          We retrospectively reviewed the presentation, diagnosis, treatment, and outcomes of patients with closed injury of the cervical trachea. We evaluated factors that improve diagnosis and treatment, reduce mortality, and avoid tracheal stenosis.

          Methods

          We reviewed the clinical data of 17 patients with closed injury of the cervical trachea. All patients underwent CT scanning or endoscopy, tracheal exploration, low tracheotomy, and tracheal repair.

          Results

          In 12 patients, breathing, phonation, and swallowing functions had returned to normal at 2 weeks. In three patients, breathing and swallowing functions had recovered at 2 weeks, but hoarseness continued. In two patients, tracheal stenosis prevented extubation and required further surgery; in these patients breathing and swallowing functions had recovered at 6 months.

          Conclusions

          Closed injury of the cervical trachea may cause airway obstruction and is potentially life-threatening. Early diagnosis and repair to restore structure and function are important to ensure survival and avoid tracheal stenosis.

          Traumatic injury to the trachea and bronchus.

          Tracheobronchial injuries are relatively uncommon, often require a degree of clinical suspicion to make the diagnosis, and usually require immediate management. The primary initial goals are twofold: stabilize the airway and define the extent and location of injury. These are often facilitated by flexible bronchoscopy, in the hands of a surgeon capable of managing these injuries. Most penetrating injuries occur in the cervical area. Most blunt injuries occur in the distal trachea or right mainstem, and are best approached by a right posterolateral thoracotomy. Choice and timing of approach are dictated by the presence and severity of associated injuries. The mainstay of intraoperative management remains a single-lumen endotracheal tube. Most injuries can be repaired by simple techniques, using interrupted sutures, but some require complex reconstructive techniques. Follow-up to detect stenosis or anastomotic technique is important, as is attention to pulmonary toilet.

            Tracheobronchial injury.

            Tracheobronchial injuries (TBI) can be challenging to diagnose, manage, and definitively treat. They encompass a heterogeneous group of injuries that are often associated with other injuries. Although relatively rare, diagnosis and treatment of TBI often requires skillful and creative airway management, careful diagnostic evaluation, and operative repairs that are often resourceful and necessarily unique to the given injury. An experienced surgeon with a high level of suspicion and the liberal use of bronchoscopy constitute the major tools necessary for diagnosing and treating these injuries. Most TBI can be repaired primarily using a tailored surgical approach and techniques specific to the injury. Associated injuries are common, and surgeons must be knowledgeable in treating a wide variety of physiologic abnormalities, especially those involving the chest wall and lung parenchyma, if a successful outcome is to be achieved in the management of these often challenging patients.

              Acute major airway injuries: clinical features and management.

              Patients with an acute major airway injury are coming at our attention with increasing frequency. Despite of its nature, post-traumatic or iatrogenic, these lesions may be life-threatening. An early diagnosis and a prompt treatment reduce morbidity and mortality. In the last 10 years, on a total of 55 patients treated in our institution for benign lesions of the major airway, 20 were with an acute injury; eleven females and nine males with a mean age of 58 years (range of 24--92). Twelve lesions were iatrogenic (orotracheal intubation) and eight were post-traumatic (three blunt traumas, five penetrating traumas). The cervical trachea was involved in 13 cases (one associated to an incomplete esophageal transection and two associated to laryngeal injuries), the thoracic trachea in six cases (four extended to the right mainstem one and to the left). Sixteen patients underwent immediate surgical repair (13 direct sutures of the tear and three complex restorations of the airway): 11 by cervicotomy and five by thoracotomy. In six cases the suture of a posterior tracheal wall tear was achieved through a new approach which provides for a small collar incision and a longitudinal tracheotomy. All the patients were discharged healed with a normal patency of the airway. At a mean follow up of 49 months (range of 9--122) endoscopy showed a perfect healing process of the lesions. One patient, treated in a conservative fashion, required endoscopic laser Nd-YAG removal of a granuloma. Early diagnosis and surgical repair are the goals to persecute to achieve the best outcomes in this potentially lethal lesions. The surgical approach should be the thoracotomy if the trauma involves the 1/3 inferior trachea and/or a mainstem, the cervicotomy in the case it was injured the 2/3 superior trachea and the larynx. Posterior tracheal wall tears may be repaired via the new transcervical/transtracheal technique. The conservative treatment should be reserved to those patients with minimal signs and symptoms, and with an adequate patency of the airways.
