Network Interpretation Endobronchial ultrasound
Expansion:
Ultrasound bronchoscopy is a device that has an ultrasound probe mounted on the front end of the bronchoscope that allows for real-time ultrasound-guided transtibial needle aspiration biopsy (EBUS-TBNA) .
Some extra-bronchial lesions are the "blind spot" of conventional fiberoptic bronchoscopy because conventional bronchoscopy can only visualize the lesions located in the trachea and bronchus, but is often unable to do anything about the extra-bronchial lesions. EBUS can locate the exact location of the extra-bronchial lesion by ultrasound, and avoid the blood vessels under the guidance of Doppler, and obtain the cells and tissues in the corresponding area through needle aspiration and biopsy, so as to achieve the purpose of diagnosing the disease.
EBUS-TBNA can clearly show the relationship between blood vessels, lymph nodes, and space-occupying lesions in the mediastinum outside the airway, and performs trans-tracheobronchial needle aspiration biopsy under real-time monitoring of ultrasound images, which completely solves the problem of traditional TBNA that can only be performed "blindly" and effectively avoids damages to the peripheral blood vessels, and improves the safety of this technology. It effectively avoids damage to the surrounding blood vessels and improves the safety and accuracy of the technique. Compared with mediastinoscopy, EBUS-TBNA does not require tracheal intubation, is minimally invasive and safe, and is easier to perform and less expensive.
EBUS-TBNA is mainly used for staging lymph node metastasis in lung cancer, but also for diagnosing intrapulmonary tumors, unexplained hilar and/or mediastinal lymph node enlargement, and mediastinal tumors.
