Pulmonary barotrauma as the cause of pneumoretropharynx in pulmonary lymphangioleiomyomatosis.

A 55-year-old white woman with pulmonary lymphangioleiomyomatosis (LAM) presented to the emergency department with odynophagia and subplatysmal emphysema after a paroxysm of coughing. Lateral neck films showed subcutaneous emphysema and a retropharyngeal air stripe. Chest radiographs showed neither pneumothorax nor pneumomediastinum. Patients with LAM frequently develop pulmonary barotrauma and pneumothoracies. This patient, however, had undergone prior bilateral talc pleuradesis as treatment for recurrent pneumothoracies and, thus, could not manifest this complication of barotrauma. This case illustrates the uncommon occurrence of superior dissection of air after pulmonary barotrauma.

Current assessment and management of spontaneous pneumomediastinum: experience in 24 adult patients.

OBJECTIVES: Spontaneous pneumomediastinum (SPM) is an uncommon, benign, self-limited disorder that usually occurs in young adults without any apparent precipitating factor or disease. The purpose of this study was to review our experience in dealing with this entity and detail a reasonable course of assessment and management. METHODS: A retrospective case series was conducted to identify adult patients with SPM who were diagnosed and treated in a single institution between 1993 and 2000. RESULTS: Twenty-four patients were identified who included 18 men and 6 women with a mean age of 17.5 years. Acute onset chest pain was the predominant symptom at presentation. Only half of the patients developed clinically evident subcutaneous emphysema. The most frequent precipitating factor was a history of illegal drug abuse seen in 25% of patients. Other factors included asthmatic bronchospasm, physical activity and violent coughing or vomiting. Chest radiography and computerized tomography (CT) were diagnostic in all cases with CT scan revealing six cases with associated pulmonary abnormalities. Esophagogram and flexible bronchoscopy were selectively used. Twelve patients (50%) were admitted to the hospital. Their mean hospital stay was 2 days. All patients were conservatively treated. In a follow-up of 3-10 years no complications or recurrences were observed. CONCLUSIONS: SPM follows alveolar rupture in the pulmonary interstitium. It shows a rising incidence in young drug users. It has a wide range of clinical features necessitating a high index of suspicion. Chest X-ray and CT scan should be always performed. Hospitalization and aggressive approach should be limited. SPM responds well to conservative treatment and follows a benign natural course.

[Diagnosis, procedures and conservative therapy of a bronchial rupture after intubation with double-lumen tube].

Bronchial rupture is a rare but severe complication of intubation with a double-lumen tube. Cardinal symptoms are mediastinal and subcutaneous emphysema as well as pneumothorax. Larger injuries result in an air leak and the endtidal carbon dioxide decreases. The gas exchange may worsen drastically when mucosal prolapse or bronchial haemorrhagia lead to bronchial occlusion. Mediastinitis or sepsis can be the sequel of the opened mediastinum. If bronchial injury is suspected probably fibreoptic bronchoscopy is indicated. We report on a case of bronchial rupture due to overinflation of the endobronchial cuff or movement of the inflated cuff when repositioning the patient. The conservative therapy was successful in spite of the fact that surgical intervention is recommended in the literature following bronchial rupture. To avoid tracheobronchial injuries an adequate tubus size must be selected. The more flexible polyvinylchloride (PVC) tubes without a carinal hook should be preferred to the Carlens tube. An atraumatic intubation is promoted by leaving the stylet inside after the tip of the tube has passed the vocal cords. To identify the minimum occlusive pressure of the endobronchial cuff for lung isolation different methods are described and should be used. The cuff has to be deflated when the patient is repositioned and when one-lung-ventilation is not required. Tumours of the tracheobronchial tree and weakness of the bronchial wall caused by steroid hormone therapy or COPD may increase the risk of tracheobronchial laceration.

[Spontaneous pneumomediastinum and idiopathic pulmonary fibrosis].

The association between pulmonary fibrosis and pneumomediastinum is infrequent. Computed tomography is the suited method for the detection of small pneumomediastinum, which is difficult to detect by chest radiography. A case of idiopathic pulmonary fibrosis, with frequent and violent cough, with pneumomediastinum and cervical subcutaneous emphysema, without pneumothorax, probably caused by rupture of bullae is presented. The outcome was favourable with symptomatic treatment.

[A six-year-old girl with dyspnea following tracheocutaneous repair].

BACKGROUND: A few patients develop prominent scars combined with persistent fistula after the removal of a long-standing tracheostomy tube. The procedure needed to correct the condition is generally considered minor surgery, normally without any significant complications. We describe, however, a patient who developed a particularly complicated postoperative course. MATERIAL AND METHODS: The patient was a six-year-old girl who underwent surgery because of significant scar formation and a persistent small tracheocutaneous fistula eight months after removal of the tube. Postoperatively she had a cough attack and developed spontaneously subcutaneous emphysema, pneumomediastinum and bilateral pneumothorax. She required intensive care, thoracic drainage and antibiotic prophylaxis. Over the next days her situation improved and she was discharged on the sixth day. INTERPRETATION: Operative treatment of scarring after tracheostomy in which the surgeon also confronts a tracheocutaneous fistula or an opening into the tracheal lumen requires postoperative observation so that any severe complications can be managed.

Intraoperative life-threatening emphysema associated with endotracheal intubation and air insufflation devices: report of two cases.

Two cases of life-threatening body emphysema with decompensating pneumothoraces, pneumomediastinum, and pneumopericardium intraoperatively have been presented. The most likely cause was tracheal perforation combined with high pressure ventilation. Although subcutaneous emphysema and pneumomediastinum are self-limiting conditions with rapid recovery with conservative treatment, life-threatening complications may arise requiring prompt recognition and specific surgical management in order to save the patient's life.

Anterior infradiaphragmatic free gas following bronchial rupture: case report and literature review.

Bronchial rupture is an uncommon injury that presents clinically and radiologically with tension or non-tension pneumothorax, pneumomediastinum and subcutaneous emphysema caused by air leak and migration of free gas. Infradiaphragmatic gas has previously been demonstrated in mechanically ventilated patients with pneumomediastinum and is secondary to passage of air via anterior and posterior trans-diaphragmatic pathways. We present a case of bronchial rupture complicated by extensive infradiaphragmatic gas following mechanical ventilation that illustrates these pathways and some of the major radiographic signs associated with this injury.

Otologic complications following the use of a high-speed air-turbine handpiece.

The use of high-speed instruments may result in subcutaneous air in the face and neck. Hearing loss and otalgia have been added to the previously reported sequelae. Careful use of air-driven high-speed handpieces around areas of weakened and disrupted oral tissues may help avoid subcutaneous emphysema. Awareness of this entity plays a significant role in appropriate diagnosis and treatment.

[Computed tomography in the diagnosis of pulmonary barotrauma associated with the adult respiratory distress syndrome].

In the patients suffering from adult respiratory distress syndrome (ARDS), pulmonary barotrauma is a frequent and fearful complication, whose timely and accurate diagnosis is therefore needed. To this purpose, bedside chest films often exhibit some diagnostic drawbacks. Computed tomography (CT) of the chest is rarely used because of the problems concerning the transfer and the control of these critically ill patients outside the Intensive Care Unit. The chest CT findings of 84 ARDS patients were retrospectively reviewed, investigating: a) the presence of barotrauma (pulmonary bullae, pneumothorax, pneumomediastinum, subcutaneous emphysema); b) the positioning of thoracostomy tubes; c) the chest films performed on the same day as CT. CT showed the presence of barotrauma in 41 patients. Pulmonary bullae were seen in 26 cases (31%), pneumothorax (mainly in anteromedial location) in 27 cases (32%) and pneumomediastinum in 11 cases (13%). In 22 patients with thoracostomy tubes CT demonstrated the exact site of the drainages: in 7 cases only the tubes were correctly positioned, or were working properly. The presence of pulmonary bullae (regarded as the evidence of interstitial pulmonary emphysema) proved to be associated with a higher mortality rate than that of the entire sample (58% vs 38%); in 30 of 41 patients with barotrauma (73%) CT proved to be superior to chest films, especially to demonstrate pulmonary bullae (26 cases detected by CT vs 7 cases diagnosed by chest films). In 14 of 41 patients with barotrauma the information yielded by CT directed the choice of treatment: thoracostomy tubes were positioned in the cases of pneumothorax undetected by chest films and in the cases of only partially drained multilocular pneumothorax, or replaced in the event of tube mispositioning. In conclusions, in ARDS patients the use of chest CT is recommended in selected cases only, when complications (especially barotrauma) are suspected and unrevealed by bedside chest films.

Small intestinal perforation and necrotizing fasciitis after abdominal liposuction.

Liposuction, the most common aesthetic procedure performed in the United States, is not without risk, but the overall complication rate in the literature varies from less than 1% to 9.3%. A 55-year-old woman who had undergone abdominal liposuction with bilateral breast augmentation was hospitalized in a state of profound septic shock. A diagnosis of necrotizing fasciitis was made on the basis of findings that included abdominal skin discoloration, subcutaneous emphysema, and air in the subcutaneous plane seen on abdominal computed tomography (CT) scan. During the operative procedure for abdominal wall debridement, extensive necrosis of abdominal wall fascia with leakage of bilious fluid from defects in the rectus sheath was found. Subsequent peritoneal cavity exploration showed two perforations in the mid ileum with gross peritoneal cavity contamination.

Epidural emphysema associated with primary spontaneous pneumothorax.

A 21-year-old male patient was admitted with spontaneous pneumothorax, and no history of asthma. Closed drainage treatment was unsuccessful. Chest computed tomography demonstrated pneumomediastinum and subcutaneous emphysema with multiple air bubbles within the spinal canal between the levels Th3 and Th11. Resection of bullae on the upper lobe and partial pleurectomy were performed. Postoperative period was uneventful. Epidural emphysema was resolved spontaneously without neurologic symptoms and signs. Intraspinal air, or pneumorachis, associated with spontaneous pneumothorax and pneumomediastinum is an extremely rare condition. We discussed spontaneous pneumothorax and pneumomediastinum as well as epidural pneumatosis and reviewed reported cases in the literature.
