Drug use-related right-sided infective endocarditis complicated by empyema and bronchopleural fistula

Right-sided infective endocarditis is frequently accompanied by septic pulmonary emboli, which may result in a spectrum of respiratory complications. We present the case of a 25-year-old woman diagnosed with infective endocarditis secondary to intravenous drug use. During a long and arduous hospital course, the patient developed empyema with bronchopleural fistula, representing severe but uncommon sequelae that may arise from this disease process. She was treated with several weeks of antibiotics as well as surgical thorascopic decortication and parietal pleurectomy.

Selective Bronchial Occlusion for Treatment of a Bronchopleural Fistula in an Extremely Preterm Infant

Neonatal pulmonary air leak commonly occurs as a complication of mechanical ventilation in infants with underlying hyaline membrane disease. They can commonly be managed conservatively or with the application of a chest drain, but some severe cases pose a significant challenge in finding an alternative therapeutic solution. Selective bronchial occlusion represents an unconventional rescue therapy for treating bronchopleural fistula resistant to the standard therapy. A 27-week gestation preterm infant ventilated for respiratory distress syndrome developed tension right-sided pneumothorax. Conventional modalities of treatment were tried and were unsuccessful. Intermittent selective bronchial occlusion with a Fogarty’s catheter and high-frequency oscillatory ventilation resulted in considerable improvement in the infant’s clinical condition and radiographic findings.

Bronchopleural Fistula associated Tension Pneumothorax in SARS- COVID 19: A case report

COVID-19 can cause pneumothorax but pneumothorax in COVID-19 patient associated with bronchopleural fistula is very rarely reported. We present this unusual case of Tension Pneumothorax in COVID -19 Patient associated with Bronchopleural Fistula.

A pneumatocele observed in the thoracic cavity after bronchoalveolar lavage

A 76-year-old man was admitted to the respiratory medicine department with 5 days of a non-productive cough and exertional dyspnea. A computed tomography revealed multiple mild patchy consolidations in both lungs (Figure 1). Despite antibiotic therapy, there was poor improvement in laboratory and radiological parameters. A bronchoscopy was performed on day 5. The bronchoscopy was wedged in left B5 and a bronchoalveolar lavage (BAL) was performed. After the BAL, we noticed a fistula in the depth of left B5 and saw a structure like a pleural cavity in the back of the fistula (Figure 2). We diagnosed the patient’s condition as pneumatocele (PC). BAL showed 46% lymphocytes and the CD4/8 ratio as 3:7. These findings suggested cryptogenic organizing pneumonia (COP). It took 3 weeks for the PC to improve. Bilateral multiple consolidations improved after the administration of a steroid (PSL 0.5 mg/kg). PCs can occur in infections, chest trauma, barotrauma from mechanical ventilation, and bronchial interventions [1,2]. The mechanism of PC formation is closely related to that of a check valve. The check valve may be composed of exudate from inflammation and the destroyed wall of the respiratory tract [3]. In this case, it was considered that the wedged bronchoscopy and collapsed bronchial wall became the check-valve. PCs can be a severe condition including tension pneumothorax, bronchopleural fistula, and secondary infections [4]. In our case, as we were concerned about new complications due to the PC we did not prescribe a steroid for COP until the PC had improved. To our knowledge, no papers have reported internal observations of PC. We herein report the first case of PC observed in the thoracic cavity after BAL.
