Interventional pulmonology is a relatively new specialty within the practice of pulmonology and critical care medicine that has dramatically changed the approach to diagnosing and treating pleural (lung) diseases. evaluating pulmonary nodules, diagnosing and staging lung cancer and treating lung cancer. The scope of this practice concentrates on diseases involving the airways and the pleural cavities (the area surrounding the lungs). In addition to the general practice of pulmonology, a big part of the interventional pulmonary practice concentrates on procedures that require special training that general pulmonologists usually do not acquire during their fellowship. Interventional pulmonologist Dr. Yousef Shweihat is one of the few in the country who underwent extensive training through undergoing a special fellowship to acquire experience in this new field.
These are two procedures that usually require a lung doctor and a GI doctor (gastroenterologist or stomach doctor) to perform. Because Dr. Shwiehat is specially trained in both procedures, he can perform them both himself using one small scope.This procedure can be used for:
This is a very old procedure that has been replaced by flexible bronchoscopy. Recently, there has been an increased interest in this procedure in treating airway obstruction (blockage). Patients with obstruction of the airway due to cancer, a foreign body or a benign disease might benefit from such a procedure. The only way to insert certain types of stents or devices to treat the airways is through the rigid scope, and our center is one of few in the country to offer this procedure.
Airway stents are similar to coronary (heart) stents. They are usually used if the airways are blocked or collapse easily after treating a blockage. They are used for both benign and malignant disease. Our program is well equipped for placing all kinds of available stents.
Many modalities are available for removing tumor or opening airway obstruction. Electrocautery, APC and laser therapy are a few of the most commonly used procedures to achieve airway patency. Our pulmonologist had special training in applying such therapies through flexible and rigid bronchoscopy.
Many of the diseases that cause such diseases are benign, but they can be malignant too. The application of ablative therapy through flexible or rigid bronchoscopy is one way to avoid surgery. The endoscopic treatment of these diseases is equivalent if not superior to the complex surgery often recommended to treat these diseases.
Pleural effusion, the collection of fluids around the lungs, can be caused by many diseases. Often, these diseases are hard to diagnose and treat. Our lung program offers less invasive techniques for diagnosis and treatment that can often replace surgery.
This procedure is much less invasive than the open surgical technique and yields similar results. During a pleuroscopy, a scope is placed in the chest to examine the pleural cavity, where the fluid collects, and take biopsies and seal the space if necessary. A pleuroscopy is typically much better tolerated than the surgical approach, with fewer complications. After the procedure, the patient is expected to be in the hospital for few days with a chest tube in the side. For selected patients, an indwelling catheter can be placed at time of the procedure.
Often, pleural effusion recurs even after surgical treatment. In instances, patients are not fit enough to undergo surgery or pleuroscopy for treatment. The insertion of a catheter that the patient can use to empty fluids from the chest(whether malignant or not) makes patients more mobile and able to go home with such a catheter. The catheter itself will cause the space where the fluid collects to get sealed in about 70% of patients. If that happens, the tube can be removed easily in the office. This is an outpatient procedure and patients can go home the same day with their care givers.
Many patients need oxygen for their chronic pulmonary diseases. Often, even with the use of adequate oxygen, their activity is limited due to dyspnea. For certain patients, the insertion of the transtracheal oxygen catheter, a catheter that delivers oxygen directly in the airways, improves their exercise tolerance and their quality of life. This is an outpatient procedure and patients usually go home on the same day. This procedure is only available at a few centers in the country.
A new procedure has been developed to help patients with severe asthma and persistent symptoms despite optimal medical therapy. Airway thermoplasty uses heat to treat the muscles of the airways. It may help patients reduce their symptoms and reduce or phase out certain medications. Airway thermoplasty treats the main cause of airway obstruction in asthma patients, and it is available in our center through our asthma clinic.
Electromagnetic navigational bronchoscopy enables the pulmonolgist to reach areas in the lung using a special magnetic field. It enables the pulmonologist to biopsy very small nodules that previously required a CT-guided biopsy.
In addition to these procedures, our Interventional Pulmonology Program accepts referrals for all forms of diagnostic bronchoscopy and bronchoscopic lung biopses.
