Is there any serious problem ? What should be the line treatment?Thanks and regards  <response>: Thanks for your question on Chat Doctor. I can understand your concern. I have gone through the x-ray report you have mentioned. Most common cause for prominent bronchovascular markings is bronchitis. So if you are smoker or having breathing difficulty then get done PFT Pulmonary Function Test. If PFT is normal then no need to worry, just quit smoking. But if PFT is showing obstructive defect then you will need smoking cessation, inhaled bronchodilators formoterol or albuterol and inhaled corticosteroid ICS budesonide or fluticasone. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
