A cost-effective thoracoscopic treatment strategy for pediatric spontaneous pneumothorax.

BACKGROUND: Recent data suggest that children have a higher incidence of recurrence than adults after nonoperative treatment of primary spontaneous pneumothorax (PSP). Video-assisted thoracoscopic surgery (VATS) allows efficacious therapy with significantly less morbidity. We attempt to define the most cost-effective clinically efficacious strategy using VATS to manage pediatric PSP. METHODS: We retrospectively reviewed all admissions to a tertiary care children's hospital for PSP between January 1, 1991 and June 30, 1996. RESULTS: Fifteen children had 29 primary or recurrent PSPs. Mean patient age was 14.8 +/- 1.1 years, boy-girl ratio 4:1, median body mass index 18 (normal, 20-25), and 67% of pneumothoraces left sided. All patients were managed initially nonoperatively: 14 with tube thoracostomy drainage and 1 with oxygen alone. Of the children initially managed nonoperatively, 57% had a recurrent pneumothorax, and 50% of these patients eventually developed contralateral pneumothoraces. Nonoperative treatment for recurrence resulted in a 75% second recurrence rate. In contrast, eight children who underwent operative management had a 9% incidence of recurrence. The total for charges accrued in treating 29 pneumothoraces in these 15 patients was approximately $315,000. In the same population, the estimated charges for initial nonoperative therapy followed by bilateral thoracoscopy after a single recurrence would be $230,000. CONCLUSIONS: A cost-effective treatment strategy for pediatric primary spontaneous pneumothorax is tube thoracostomy at first presentation, followed by VATS with thoracoscopic bleb resection and pleurodesis for patients who experience recurrent pneumothorax.

Spontaneous pneumothorax and pneumomediastinum in IPF.

Patients with idiopathic pulmonary fibrosis (IPF) are at risk for a variety of acute pulmonary complications, including pneumothorax and pneumomediastinum. Our aim was to describe the radiographic and CT findings and to determine the frequency of complicating spontaneous pneumothorax and pneumomediastinum in patients with IPF. A retrospective study was performed including 78 consecutive patients who underwent CT scanning of the chest and who had confirmed IPF. The chest radiographs and CT scans were reviewed by two chest radiologists and classified as showing features of extra-alveolar air collections. The CT scans showed extra-alveolar air in 9 (11.2 %) of 78 patients (six females and three males; age range 26-90 years, mean age 65 years). Pneumothorax was demonstrated in 5 patients and mediastinal air collections in 4 patients. All patients had dyspnea for 1-48 months (mean 14 months). Of the five cases with pneumothorax, four developed acute onset of dyspnea and pleuritic chest pain, whereas 1 patient had a relatively stable functional status. Of the 4 patients with pneumomediastinum, three presented with nonpleuritic chest pain and acute dyspnea. Chest radiographs showed extra-alveolar air in 6 patients. Three cases were predicted to be negative by chest radiographs. Follow-up CT showed that air collections had resolved completely in 5 patients. Two patients died of respiratory failure within 4 months after CT. Extra-alveolar air should be recognized as a relatively common IPF-related complication. Chest CT is a useful imaging method in determining air collections in patients with IPF that become acutely breathless and their chest radiograph fails to reveal the presence of extra-alveolar air.

Symptomatic spontaneous pneumothorax in term newborns.

The causes and risk factors of symptomatic spontaneous pneumothorax in term newborns are not completely understood. In the present study, our aim was to investigate the risk factors for and clinical and laboratory characteristics of term newborns with spontaneous symptomatic pneumothorax and to evaluate the outcome of management in this condition. A total of 11 term newborns admitted to the newborn intensive care unit with a diagnosis of symptomatic spontaneous pneumothorax were included during a 22-month period. Female to male ratio was 4:7, mean gestational age was 39.5 weeks, and 63% were delivered with a cesarean section, 18% of patients had renal and 55% had congenital cardiac anomalies. Rate of cardiac anomalies was more frequent in the study group compared to control group. Echocardiography in addition to renal ultrasonography may also be needed in term newborns with spontaneous symptomatic pneumothorax and further studies may be warranted to evaluate this association.

Thoracoscopic surgery for pneumothorax in older patients.

BACKGROUND: Secondary pneumothorax is more common in older pneumothorax patients. Therefore, we set out to investigate the usefulness of thoracoscopic surgery in this group. METHODS: A total of 59 operations were performed on patients aged > or = 50 years, with the goal of excising only the lesions responsible for air leaks by using the minimum degree of dissection. If the patients were found to have numerous bullae, the lesions responsible were identified by pleurography. The duration of chest tube drainage, hospital stay, and recurrence were assessed. RESULTS: The air leaks stopped and all patients were discharged without drains. Postoperative drainage time was 3.8 +/- 3.0 days. Postoperative hospital stay was 10.8 +/- 9.2 days. Six patients died of other diseases, but there was only one recurrence of pneumothorax. CONCLUSION: We consider video-assisted thoracic surgery (VATS), with the goal of excising only the lesions responsible for air leaks, to be particularly efficacious in older pneumothorax patients.

Spontaneous pneumothorax secondary to radiographically occult lung metastasis from parapharyngeal synovial sarcoma: report of a case.

This report describes a case of secondary pneumothorax caused by a radiographically occult lung metastasis from parapharyngeal synovial sarcoma, a relatively rare tumor known to be highly metastatic to the lung. Although chest X-ray and thoracic computed tomography scan failed to detect the metastatic nodule in the right lung, the surgically resected specimen proved to be a 3-mm lung metastasis. To our knowledge, only eight cases of lung metastases from synovial sarcoma causing pneumothorax have ever been reported. In most of these cases, the lung metastases were detected by radiographical examinations. However, in this patient, the metastatic lesion was not detected during examination. It is speculated that secondary pneumothorax caused by synovial sarcoma may occur during the early stages of lung metastasis. Therefore, if pneumothorax occurs in a patient with a synovial sarcoma, the possibility of lung metastasis should be carefully considered, even if it is undetectable on radiological examinations.

Pneumothorax as a presenting manifestation of early sarcoidosis.

Pneumothorax rarely develops sarcoidosis. A 21-year-old man with early sarcoidosis presenting as pneumothorax is reported. The patient came to our institute with severe chest pain and dyspnea. Plain chest roentgenograms revealed pneumothorax in the left lung. A chest tube was inserted to inflate the lung. Subsequent computed tomography demonstrated subpleural blebs in the upper lobe of the left lung. Continuous treatment with tube drainage was performed. However, surgical intervention was needed since long-term tube drainage turned out to be unsuccessful. Thoracoscopic partial extirpation on the left upper lobe was performed. The histology of the obtained lung tissue showed non-caseating granulomas composed of epithelioid cells and occasional giant cells. A diagnosis of sarcoidosis was made on the basis of the histological report. Although early sarcoidosis presenting as pneumothorax is rare in young patients, the possibility of a sarcoidosis should be considered.

Spontaneous pneumothorax and a coexistent azygos lobe.

We present a primary spontaneous pneumothorax involving a possible diagnostic and surgical pitfall. A 25-year-old man with a previously identified azygos lobe was admitted to our hospital because of right primary spontaneous pneumothorax. A preoperative chest X-ray at the onset of the pneumothorax as well as after resolution by tube drainage showed an azygos fissure but no azygos vein. Chest computed tomography revealed the dislocated azygos vein external to the azygos fissure on the mediastinal side of the reexpanded upper lobe. Thoracoscopic bullectomies were uneventfully performed. The azygos arch was found dangling in the free inferior border of the mesoazygos. An azygos vein located in this position can be a potential surgical hazard especially in video-assisted thoracic surgery. This case suggests that the presence of an azygos lobe can be missed on chest X-ray when a pneumothorax occurs in a patient with an azygos lobe.

Management of pneumothorax and barotrauma: current concepts.

Pneumothorax can be spontaneous, traumatic or iatrogenic. Pneumothorax ex vacuo, sports-related pneumothorax and barotrauma unrelated to mechanical ventilation are interesting and newer entities. Management consists of getting rid of the air and prevention of recurrence of pneumothorax.

Value of computed tomography of the lung in the management of primary spontaneous pneumothorax.

The treatment of patients with primary spontaneous pneumothorax remains controversial, since recurrence and the ultimate need for thoracotomy [corrected] cannot be predicted. In the current study, computed tomography (CT) of the lung was performed prospectively on 26 consecutive patients with primary spontaneous pneumothorax to determine whether the size and/or the number of apical blebs would correlate with recurrence and/or need for thoracotomy [corrected]. Both the number of blebs and the bleb score (calculated by the number of blebs multiplied by a numeric value assigned a range of bleb sizes) of the affected lung was significantly greater in patients with a history of recurrent pneumothorax and/or ultimate need for thoracotomy [corrected] as treatment. CT of the lung may be useful in predicting the natural history of pneumothorax.

Tension pneumothorax during extracorporeal membrane oxygenation.

Life-threatening tension pneumothorax in neonates on extracorporeal membrane oxygenation (ECMO) has been associated with an increase in arterial oxygen tension and a decrease in peripheral perfusion, followed by a decrease in ECMO flow with progressive hemodynamic deterioration. To investigate this triad, chest tubes were placed bilaterally in 9 dogs to allow injection of air to produce tension pneumothorax. Six dogs were subsequently placed on standard venoarterial ECMO before the reinduction of tension pneumothorax. Measured values included arterial pulse pressure, inferior vena cava pressure, systemic arterial blood gases, peripheral arterial oxygen saturation, mixed venous oxygen saturation, and left heart cardiac output. Oxygen delivery was calculated from directly measured values. Each of the 6 dogs on ECMO demonstrated the triad of increased arterial oxygen tension (92 +/- 7 to 325 +/- 20 mm Hg; p less than 0.05), decreased peripheral perfusion (as evidenced by a decrease in pulse pressure from 55 +/- 4 to 31 +/- 5 mm Hg; p less than 0.05), and decreased mixed venous oxygen saturation (71% +/- 3% to 22% +/- 2% saturation; p less than 0.05) followed by a lower ECMO flow with progressive hemodynamic deterioration (oxygen delivery decreased from 285 +/- 11 to 111 +/- 12 mL/min; p less than 0.05). Aspiration of the intrathoracic air allowed return to baseline ECMO flow and hemodynamic stability in all dogs. The triad of increased arterial oxygen tension and decreased peripheral perfusion (as evidenced by a lower arterial pulse pressure and lower mixed venous oxygen saturation) followed by decreased ECMO flow with progressive hemodynamic deterioration consistently appears when tension pneumothorax occurs on ECMO.

Pneumothorax in cystic fibrosis: a 26-year experience.

We reviewed the records of all patients with cystic fibrosis and radiologically demonstrated pneumothorax at Rainbow Babies and Childrens Hospital between 1959 and 1987. There occurred 144 pneumothoraces, 71 right and 73 left, in 99 patients, 48 female and 51 male. The median survival from the date of the first pneumothorax was 29.9 months. Primary therapy included the following: observation; tube thoracostomy; tube thoracostomy with instillation of quinacrine hydrochloride, tetracycline, silver nitrate, or talc; or partial pleurectomy. Complications were minimal in each group. The surgical group did significantly better than all other groups except the group given talc. We conclude that pneumothorax is a late and ominous complication of cystic fibrosis. The primary treatment of pneumothorax should be partial pleurectomy. Talc instillation should be reserved for patients in respiratory failure who are too ill to undergo operation and for the occasional patient in whom surgical intervention fails.

Spontaneous pneumothorax: a single-institution, 12-year experience in patients under 16 years of age.

OBJECTIVE: To characterize the natural history and outcome of spontaneous pneumothorax in patients under age 16 years. DESIGN: This is a retrospective review in which all patients admitted to the authors' institution (between December 1980 and July 1993) with a diagnosis of spontaneous pneumothorax were included. Information was obtained from the hospital records. SETTING: This study was performed in a university childrens' hospital. PATIENTS: All patients under 16 years with a diagnosis of spontaneous pneumothorax were included. RESULTS: Seventeen patients were admitted and analyzed. Only three admissions were for recurrence. The main symptoms included chest pain (100%), shortness of breath (41%), and cough (6%). Chest tube drainage was successful in 65% of the cases; the median time was 4 days. Two patients had a persistent air leak. An underlying cause was recognized in 42% of cases. Seven operations were necessary, and the mean follow-up periods is 31 months, with no recurrence reported to date. CONCLUSION: Spontaneous pneumothorax occurs in the pediatric population, although it is less common in adults. An underlying pathology is more frequently observed in pediatric patients, but recurrence is less common. Chest tube drainage alone is sufficient treatment for the majority of patients; however, a significant number require some form of surgical intervention.

Spontaneous pneumothorax complicating pregnancy--case report and review of the literature.

Patients with a spontaneous pneumothorax frequently present for care in the emergency department. The occurrence of spontaneous pneumothorax during parturition occurs rarely. We describe a case of spontaneous pneumothorax during the first trimester of pregnancy, which resolved with tube thoracostomy. The patient delivered vaginally a healthy 4.3 kg male at term under epidural anesthesia. We discuss spontaneous pneumothorax and review reported cases during pregnancy.

Local anesthesia infiltration as a cause of intraoperative tension pneumothorax in a young healthy woman undergoing breast augmentation with general anesthesia.

Pneumothorax may be a medical emergency. Iatrogenic pneumothorax is more common than all other forms of spontaneous pneumothorax, and surgical procedures involving the breast are a frequent setting for this. A 32-year-old, 60 kg, woman without any significant medical history underwent a bilateral breast augmentation and rhinoplasty. She underwent a routine general endotracheal anesthetic. Prior to surgical incision, the surgeon infiltrated the breast with lidocaine with epinephrine. Six hours into the surgical procedure, the patient developed hemodynamic compromise and was diagnosed with tension pneumothorax, which was treated emergently with a 14-gauge angiocatheter placed intrapleurally. The patient immediately returned to hemodynamic stability. This case report discusses iatrogenic pneumothoraces as well their most likely causes; which in this specific case was the injection of local anesthetic. Suggestions for prevention and treatment of the unusual complication are discussed.

A newborn case of congenital laryngeal cyst complicated with pneumothorax and pneumomediastinum.

Benign congenital laryngeal cysts are rare entities. They often cause chronic hoarseness and severe stridor. Case reports of congenital laryngeal cyst complicated with pneumothorax and pneumomediastinum are very rare. A 3,112 g full-term male newborn developed stridor which got worse during crying for 12 h after birth. Chest retractions were present with inspiration. Chest X-rays showed the presence of right pneumothorax and pneumomediastinum. Transnasal flexible laryngoscopic examination revealed a large cystic mass, which occupied almost the entire supraglottic airway. The operation was performed with the techniques of laryngomicrosurgery under general anesthesia. The cystic wall was punctured and serous liquid contents were aspirated. Excision of the entire cystic lesion was performed. The next day, extubation was performed without any troubles. The stridor had disappeared and the pneumothorax and pneumomediastinum were improved without further medical intervention. The histopathological examination revealed that the cystic wall consisted of normal squamous epithelial cells. It is reasonable to think that the high airway pressure due to congenital laryngeal cyst was responsible for pneumothorax and pneumomediastinum.

Late-onset occult pneumothorax after lung volume-reduction surgery.

BACKGROUND: Lung volume-reduction surgery has proved to be a reliable palliative surgical treatment for patients with severe emphysema. Nonetheless, late complications can arise after lung volume-reduction surgery although this matter has been poorly investigated by previous studies. METHODS: We report a series of 6 patients undergoing unilateral lung volume-reduction surgery at our institution between October 1995 and December 2004, who were readmitted several months after discharge because of the occurrence of occult pneumothorax mimicking acute respiratory failure. RESULTS: Occult pneumothorax occurred in 3.3% of the 182 patients treated with lung volume-reduction surgery at our institution. Patients were readmitted after a mean of 94 days (range, 20 to 700 days) from the discharge. Chest roentgenography was unable to detect the occurrence of pneumothorax, which was instead revealed by means of a computed tomographic scan in all patients. The interval between admission and correct diagnosis averaged 22.4 hours. The number of air collections ranged between two and four. Treatment entailed solely blind chest drainage placement in 2 patients and awake video-assisted thoracoscopic surgery in the others, including placement of chest tube under direct vision in 1 patient, repair of lung tears by means of cyanoacrylate glue in 2 and bovine pericardium patch plus cyanoacrylate glue apposition in 1 patient. CONCLUSIONS: In conclusion, we believe that occult pneumothorax should be kept in mind as one of the possible late complications of lung volume-reduction surgery and should be suspected whenever sudden worsening of dyspnea is noticed even in the presence of an uneventful chest roentgenogram. Awake video-assisted thoracoscopic surgery management can represent an effective option in these instances.

Modified central line for pneumothorax.

Pneumothoraxes, whether spontaneous or iatrogenic, frequently require drainage. Although the recent trend has been toward a catheter-based approach, many thoracic surgeons continue to use chest tubes. Tube thoracostomy is associated with significant pain at the time of insertion and during continued drainage. Pneumothorax catheters are less painful but more expensive, and some have been associated with significant failure. After disappointing experience with pneumothorax catheters, we have modified a central line to use in lieu of a pneumothorax kit. We have found this technique to be effective, safe, reliable, and inexpensive.
