Clinical significance and precautions of bronchography

Bronchography is a common diagnostic method in clinical medicine to examine the condition of the bronchus. For patients, it is very necessary to know some knowledge about this diagnostic method. For example, knowing some issues that need to be paid attention to before surgery and some taboos can help you get a more accurate diagnosis and assist in treatment. So, what does this knowledge about the clinical significance and precautions of bronchial angiography bring to everyone?

Bronchography is an examination method for directly observing bronchial lesions. It has good diagnostic effect, but it causes certain pain to patients. Bronchography is one of the important examination methods for chest diseases and has definite diagnostic value for bronchial diseases. It can determine the location, extent and nature of the lesion, and provide a basis for clinical selection of effective treatment methods.

The indications for bronchography include:

(1) Congenital or acquired bronchial and lung diseases, such as bronchiectasis, bronchial and lung tumors, organizing pneumonia, chronic lung abscess, and atelectasis.

(2) Chronic cough or hemoptysis of unknown cause.

(3) Recurrent pneumonia, especially pneumonia that occurs repeatedly in the same location.

(4) Unilateral hilar enlargement of uncertain nature.

(5) Differential diagnosis of chronic cavities or cysts.

(6) Localized emphysema or atelectasis.

Analysis of inspection results:

(1) If the bronchi are uneven in thickness after filling and have localized edema or dilation, the bronchi are fixed, rigid, gathered and twisted, and the contrast agent is delayed in emptying, this is common in bronchiectasis.

(2) If there is local bronchial stenosis or obstruction or compression and deformation of the lumen, it is often seen in tumors, trauma, foreign bodies, tuberculosis or inflammation.

(3) The tube wall is irregular and the contrast agent protrudes through the tube wall, which may be a bronchopleural fistula or esophageal fistula.

(1) Contraindications: ① Those with general physical impairment, advanced age, or poor heart, lung, or liver function. ② Patients with acute bronchial and lung infections and infiltrative pulmonary tuberculosis. ③ Those who have severe hemoptysis within 2 weeks. ④ People with hyperthyroidism or allergy to iodine.

(2) Before the operation, the purpose, method and possible pain of angiography should be explained in detail to the patient in order to gain the patient's cooperation.

(3) Do not eat or drink for 4 hours before and 2 hours after contrast imaging.

(4) When the amount of sputum is large, postural drainage should be performed before surgery.

(5) The contrast agent should be prepared with appropriate consistency to prevent it from entering the alveoli; change body position when injecting the contrast agent to ensure that the contrast agent is evenly distributed.

(6) Anesthesia should be adequate to prevent severe coughing from affecting the imaging effect.

(7) Postural drainage is performed after surgery to promote the rapid excretion of contrast agent.

After understanding the clinical significance and precautions of bronchial angiography, patients will have a thorough understanding of how to take care of their bodies before and after surgery. However, understanding alone is not enough. What patients need to do is to apply all this knowledge so that they can get help. This is the value of this knowledge.
