Broncho-pleural fistula embolization is a medical procedure used to treat a condition where there is an abnormal connection (fistula) between the airways in the lungs (bronchi) and the space between the lungs and the chest wall (pleural space). This can occur as a complication of lung surgery, trauma, infection, or other lung diseases. During the procedure, a catheter is guided through the blood vessels to the site of the fistula. A special material, such as coils or glue, is then injected into the fistula to block it off and prevent air or fluid from leaking into the pleural space. This helps to reduce symptoms such as coughing, shortness of breath, and fever, and allows the lung to heal. The procedure is typically performed under sedation or general anesthesia, and patients can expect a relatively quick recovery time.
