RESUMO
Primary tracheal schwannomas are rare benign tumours. This is a case report, and therefore, no specific methods or results are applicable. We here report a case of a tracheal schwannoma in an early adolescent girl presenting with subcutaneous emphysema and symptoms of airway obstruction. Tracheal resection and reconstruction by primary anastomosis were performed. Pathology confirmed the diagnosis of tracheal schwannoma. This is an unusual life-threatening presentation of a benign rare tracheal tumour with a challenging approach to management.

INTRODUCTION: Tension pneumomediastinum is an increasingly common condition since the COVID-19 pandemic's onset. It is a life-threatening complication with severe hemodynamic instability that is refractory to catecholamines. Surgical decompression with drainage is the key point of treatment. Various surgical procedures are reported in the literature, but no cohesive approach has yet been developed. AIM: The aim was to present the available options for surgical treatment of tension pneumomediastinum, as well as the post-interventional results. MATERIALS AND METHODS: Nine cervical mediastinotomies were performed on intensive-care unit (ICU) patients who developed a tension pneumomediastinum during mechanical ventilation. The age and sex of patients, surgical complications, pre- and post-intervention basic hemodynamic parameters, as well as oxygen saturation levels, were recorded and analyzed. RESULTS: The mean age of patients was 62±16 years (6 males and 3 females). No postoperative surgical complications were recorded. The average preoperative systolic blood pressure was 91±12 mmHg, the heart rate was 104±8 bpm, and the oxygen saturation level was 89±6%, while the short-term postoperative values changed to 105±6 mmHg, 101±4 bpm, and 94±5%, respectively. There was no long-term survival benefit, with a mortality rate of 100%. CONCLUSIONS: Cervical mediastinotomy is the operative method of choice in the presence of tension pneumomediastinum allowing an effective decompression of the mediastinal structures and improving the condition of the affected patients without improving the survival rate.

As the SARS-CoV-2 virus continues to infect millions of people worldwide, the medical profession is seeing a wide range of short-term and long-term complications of COVID-19. One lesser-known complication is that of pneumomediastinum. This is a rare, but significant, complication defined by the presence of air in the mediastinum with an incidence of 1.2 per 100 000. Described mortality rate is 30%, increasing to 60% in patients with concomitant pneumothoraces. Management of pneumomediastinum is typically conservative, but in cases of extensive subcutaneous emphysema, cardiac or airway compression, life-saving surgical decompression is necessary. We report a case of pneumomediastinum secondary to COVID-19, requiring a surgical approach not described in pneumomediastinum secondary to COVID-19. The case demonstrates the importance of prompt diagnosis and management, as well as the potential for good clinical outcome in selected patients.

BACKGROUND: Tension pneumomediastinum is one of the most serious complications in COVID-19 patients with respiratory distress requiring invasive mechanical ventilation. This complication can lead to rapid hemodynamic instability and death if it is not recognized in a timely manner and intervenes promptly. CASE PRESENTATION: We reported 7 COVID-19 patients with tension pneumomediastinum at a field hospital. All patients were critically ill with ARDS. These 7 patients, including 3 females and 4 males in this series, were aged between 39 and 70 years. Tension pneumomediastinum occurred on the first day of mechanical ventilation in 3 patients and later in the course of hospital stay, even 10 days after being intubated and ventilated. The tension pneumomediastinum caused hemodynamic instability and worsened respiratory mechanics with imminent cardiopulmonary collapse. In this series, we used two surgical techniques: (i) mediastinal decompression by suprasternal drainage with or without simultaneous pleural drainage in the first two cases and (ii) mediastinal drainage via suprasternal and subxiphoid incisions in 5 patients. The surgical procedures were feasible and reversed the pending cardiopulmonary collapse. Four patients had a favorable postprocedural period and were discharged from the intensive care center. Both patients undergoing suprasternal drainage died of failed/recurrent tension pneumomediastinum and nosocomial infection. Only one in five patients who underwent mediastinal drainage via suprasternal and subxiphoid incisions died of septic shock secondary to ventilator-associated pneumonia. CONCLUSION: Tension pneumomediastinum was a life-threatening complication in critically ill COVID-19 patients requiring mechanical ventilation. Surgical mediastinal decompression was the salvage procedure. The surgical technique of mediastinal drainage via suprasternal and subxiphoid incisions proved an advantage in tension relief, hemodynamic improvement and mortality reduction.

Subcutaneous emphysema is the fortuitous entry of air into subcutaneous tissue. Its occurrence in the head, neck, and mediastinum is a result of trauma or surgery. This case describes a 45-year male who presented with massive progressive subcutaneous emphysema, spreading from the peri-orbital area to the upper mediastinum, secondary to tracheal injury following blunt trauma sustained two days before presentation. We present this case to emphasize on simple management and observation of minor laryngo-tracheal trauma which can prevent further unexpected complications. In this case, we used an unconventional approach of making blowhole incision which is not in routine practice. Key Words: Subcutaneous emphysema, Blowhole, Neck trauma.

Tension pneumomediastinum is a rare but life-threatening cause of tamponade. Mechanical ventilation is a described source of tension pneumomediastinum. Here, we present a case of a 72-year-old man who developed cardiovascular collapse from tension pneumomediastinum in the setting of coronavirus disease 2019-related acute respiratory distress syndrome. We successfully performed bedside mediastinotomy and mediastinal tube placement under local anesthetic to alleviate his hemodynamic instability. Bedside mediastinotomy can be used to relieve tension pneumomediastinum in this setting.

Severe acute respiratory syndrome coronavirus 2 disease 2019 (COVID-19) has rapidly spread worldwide since December 2019. An acute respiratory distress syndrome develops in a relevant rate of patients, who require hospitalization. Among them, a nonnegligible rate of 9.8% to 15.2% of patients requires tracheal intubation for invasive ventilation. We report the case of a pneumomediastinum and subcutaneous emphysema developing in a COVID-19 patient secondary to postintubation tracheal injury. The management of COVID-19 patients can be challenging due to the risk of disease transmission to caregivers and epidemic spread. We performed a bedside tracheal injury surgical repair, after failure of conservative management, with resolution of pneumomediastinum and subcutaneous emphysema and improvement of the patient's conditions.

CASE PRESENTATION: A 64-year-old man presented for consideration for lung transplant. He had a history of previous tobacco use, OSA on CPAP therapy, and gastroesophageal reflux disease. He worked as a design engineer. The patient had a 4-year history of dyspnea on exertion, followed with periodic CT scan of the chest. Nine months prior to his evaluation for lung transplant, the patient developed worsening of dyspnea, dry cough, poor appetite, and weight loss. At times, the cough was violent and associated with chest pressure. He was prescribed systemic corticosteroids and antibiotics without improvement. Four months later, the patient noted sudden onset of severe chest pain and worsening dyspnea. A CT scan of the chest demonstrated extensive pneumomediastinum in addition to changes consistent with pulmonary fibrosis. An esophagogram showed thickening of the distal esophagus, but no signs of perforation. He was prescribed supplemental oxygen and advised to stop the use of CPAP. The patient sought a second opinion. A CT scan of the chest showed improvement of the pneumomediastinum and extensive fibrotic lung disease. Pulmonary function tests (PFTs) were consistent with a restrictive pattern, decreased diffusing capacity (Dlco), and a preserved residual volume over total lung capacity ratio. The patient was prescribed systemic corticosteroids with no improvement of his symptoms. Repeat PFTs showed further decline of Dlco, and he was referred for lung transplant evaluation.

BACKGROUND: Exacerbations of asthma constitute the most common cause of pneumomediastinum and subcutaneous emphysema in children. Foreign body aspiration is a rare cause of pneumomediastinum and subcutaneous emphysema. Foreign body aspiration leading to the occurrence of pneumomediastinum in a child with asthma may go unnoticed and be wrongly attributed to asthma, which leads to delayed diagnosis as well as to life-threatening and long-term complications. CASE PRESENTATION: We describe a case of a 6-year-old Moroccan boy with asthma who was admitted to our emergency department for acute dyspnea and persistent dry cough. The patient was initially treated as having acute asthma exacerbation. Owing to insufficient clinical and radiographic improvement with asthma treatment, a rigid bronchoscopy under general anesthesia was performed. A pumpkin seed was removed from the left main bronchus. Clinical and radiographic improvement was achieved after foreign body extraction. CONCLUSIONS: This case emphasizes that the possibility of foreign body aspiration should always and carefully be considered by the emergency physician when faced with a child with asthma presenting with pneumomediastinum and subcutaneous emphysema as an important differential diagnosis even in the absence of a history of foreign body aspiration.

INTRODUCTION: Chest pain is one of the most common symptoms with which patients report to the doctor. The reason for this is the fear of the sick, who often equate this symptom with dangerous diseases such as heart attack. The primary source of pain does not always have to be located within the chest. Colon perforation is a rare but possible complication of colonoscopy, which may result in free gas entering the mediastinum which is accompanied by chest pain. CASE REPORT: We present the case of a 78-year-old woman who reported to the hospital emergency department with chest pain, shortness of breath and abdominal pain. On the basis of imaging examinations, perforation of sigmoid affected by diverticulosis, complicated by pneumomediastinum and retroperitoneal emphysema, was suspected. The aforementioned ailments were caused by iatrogenic perforation of the sigmoid during diagnostic colonoscopy performed on an outpatient basis a few hours before reporting to the hospital. The patient was urgently qualified for laparotomy. Intraoperatively, perforation was confirmed at the rectosigmoid junction, which was the cause of retroperitoneal and pneumomediastinum with rightsided emphysema of the lateral neck region. No fluid or intestinal contents were found in the abdomen. The sigmoid colon and upper rectum were resected via double-stapled anastomosis performed between the descending colon and rectum. The patient was discharged home in good condition on the 7th postoperative day. CONCLUSIONS: Colonoscopy is a diagnostic and therapeutic procedure that is considered relatively safe, but also carries complications such as bleeding or perforation of the large intestine. Diverticular disease is a common condition which most often affects the sigmoid colon. In areas of the weakest resistance, diverticulum formation occurs as a result of increased intra-abdominal pressure, which is an additional risk factor for perforation during colonoscopy. It is important to remember the possible different clinical presentation of gastrointestinal perforation, which may also manifest as chest pain. With early detection and surgical treatment, life-threatening complications associated with the development of pneumothorax can be avoided.

A 59-year-old man with bilateral apical emphysema underwent a double lung transplant for end-stagechronic obstructive pulmonary disease leaving remnant right apical native tissue due to pleural adhesions. Initial postoperative course was uneventful until the chest drains were removed. This revealed a small pneumomediastinum, which progressively increased in size causing gross surgical emphysema. Re-insertion of the chest drain stabilised the patient so that the cause could be identified and corrected. Two bronchoscopies excluded anastomotic dehiscence as a cause. Therefore the subcostal wound was refashioned under video-assisted thoracoscopic surgery in case there was a defect. Unfortunately this also failed to halt the air leak; therefore another cause was sought. A multidisciplinary team meeting review of the radiology revealed that the patient's native bullous tissue was still inflated. Subsequent bronchoscopy revealed a native bronchial communication, due to variant anatomy, proximal to the surgical anastomosis. This was subsequently occluded using a bronchial valve allowing the patient to make a swift recovery.
