If the tumor in the lung grows bigger and compresses the large airway, the situation becomes more critical. A few days ago, 86-year-old grandmother Wang encountered a dangerous situation, because the tumor growing in the upper lobe of her right lung blocked the right main bronchus and caused difficulty in breathing, and she had to rely on her left lung to breathe. The tumor was successfully removed and the right main airway was opened, so that Wang’s grandmother safely passed the dangerous period. Before removing the tumor, a biopsy is routinely performed, however, a surprising scene occurred during this simple biopsy. “Lung cancer patients are generally rich in blood vessels where the lesions are.” Wang Jiwang told reporters that Wang’s grandmother was not an exception. During the biopsy, because Wang’s tumor was rich in blood vessels, it led to hemorrhage, and Wang’s medical team immediately gave hemostatic treatment and made her lie on her right side to prevent the blood from flowing into the left bronchus, which led to asphyxia. The bleeding was finally stopped. Although the bleeding was stopped, there were different voices in the team. Some people thought that the bleeding of Wang’s grandmother was more serious than other patients who had the same biopsy, and that the bleeding might be more serious and risky if the bronchoscopic intervention was done, but Director Wang Jiwang decided to take the risk to remove the blocked tumor after careful analysis and consideration and seeing Wang’s grandmother suffering from oxygen and infection due to the blockage. The tumor was blocked. Arterial embolization was performed before surgery to prevent bleeding, and the tumor was successfully removed “In order to prevent heavy bleeding again during surgery, we performed right bronchial artery embolization before surgery.” Wang Jiwang said that after repeated discussions with his team before the surgery, he decided to perform right bronchial artery embolization for Grandma Wang first, mainly to prevent heavy bleeding when removing the tumor for her. On the third day after the biopsy, a vascular interventional surgeon performed the right pulmonary artery embolization for Grandma Wang, and the surgery was done successfully. The bronchoscopic respiratory intervention technique completely compensates for the disadvantages mentioned earlier, as it is less invasive and more precise. With the pavement of arterial embolization in front of her, together with Wang Jiwang and his team’s skillful and skilful operation of bronchoscopic respiratory intervention, the tumor in Wang’s right large airway was successfully removed, and she resumed walking after the operation, taking care of herself completely and being able to go to the farmers’ market again. According to Director Wang Ji-wang, the current bronchoscopic respiratory intervention technique has obvious advantages for the treatment of central airway stenosis caused by benign and malignant tumors in the lung, and the results are also very good from the treated cases.
