Right pulmonary hilar angiogram is a pathological manifestation presented during chest CT examination, which is considered to be caused by pneumonia, emphysema, bronchitis, etc. It is recommended to consult a doctor for timely diagnosis. 1. Pneumonia: usually caused by bacterial or viral infection, when the right lung is repeatedly stimulated by inflammation, it may thicken the blood vessels in the right lung, and more obvious blood vessel shadows will be seen during chest CT examination. It can be treated with antibiotic drugs such as cefixime capsule or antiviral drugs such as acyclovir tablets under doctor’s supervision. 2. Emphysema: Emphysema is usually caused by long-term smoking, air pollution, etc., which leads to the expansion of the alveoli. It may lead to over-inflation of the lungs, making the peripheral blood vessels enlarged and thicker, and eventually showing the manifestation of vascular shadows in the right lung hilum. It can be treated with drugs such as budesonide formoterol inhalation powder aerosol and tiotropium bromide powder aerosol as prescribed by the doctor. 3. Bronchitis: usually due to the inflammatory reaction caused by various pathogens, some patients because of the inflammatory stimulation may lead to increased pressure in the lungs, the appearance of increased texture, manifested in the right pulmonary hilar angiography. It can be treated with drugs such as cotrimoxazole capsule and lomefloxacin hydrochloride capsule as prescribed by the doctor. If there is a right pulmonary hilar angiographic shadow, it is necessary to go to a regular hospital in time and be treated according to the specific cause of the disease.
