Benefits and risks

NICE based its recommendations on the fact that only a small amount of research has been done on the insertion of these coils. The 7 studies that NICE looked at involved a total of 208 patients.

Generally, the insertion of endobronchial nitinol coils seemed to improve people's quality of life slightly more than usual care. There was also some improvement in breathlessness and in the ability to exercise.

The studies showed that, within 6 months of the coils being inserted, risks included:

  • chest pain in up to 14% of procedures

  • pneumonia in up to 11% of procedures

  • serious worsening of chronic obstructive pulmonary disease in 17% of procedures

  • pneumothorax (air between the lung and chest wall) in 5% of procedures

  • infection of the lower airways in up to 5% of procedures.

NICE was also told about some other possible risks; bleeding and infection.

If you want to know more about the studies see the guidance. Ask your health professional to explain anything you don't understand.
