About our Practice

We provide multidisciplinary care for patients with all aspects of central airway obstruction due to either malignant or non-malignant disease. The complex airway team includes Interventional Pulmonology, Thoracic Surgery, Otolaryngology Head and Neck Surgery and Anesthesiology. Our goal is to provide expeditious care in a multidisciplinary fashion with outstanding communication to both the patient and the referring physicians. To help achieve these goals, patients are discussed at a Multidisciplinary Complex Airway Conference.

In addition to airway obstruction from malignancy, we treat non-malignant central airway obstruction due to diseases such as tracheobronchomalacia, tracheal or sub-glottic stenosis, relapsing polychondritis, amyloidosis, tracheobronchial papillomatosis, Wegener's granulomatosis and pulmonary alveolar proteinosis. We are fortunate to have all modalities for central airway intervention available to us, allowing treatment to be tailored to each patient. These technologies include:

  • Endobronchial ultrasound (EBUS)
  • Autofluorescence and narrow-band imaging
  • Thermal techniques including argon plasma coagulation (APC), electrocautery, laser and cryotherapy
  • Photodynamic therapy
  • Electromagnetic navigational bronchoscopy
  • Endobronchial brachytherapy
  • Silicone, metallic, and hybrid airway stents
  • Powered instrumentation (microdebrider)

Patients with pleural effusions, mediastinal adenopathy and lung nodules or masses are also evaluated and treated in a multidisciplinary approach with members of Interventional Pulmonology, Thoracic Surgery, Medical Oncology and Radiation Oncology. We also perform ultrasound guided pleural procedures such as placement of PleurRx® and pigtail catheters, and medical thoracoscopy in addition to whole lung lavage. Additionally, we are one of the leading centers for intrabronchial valve placement for the management of prolonged air leaks.
