CT-guided percutaneous lung puncture.
Percutaneous pulmonary puncture is a more mature operation technique, commonly used for biopsy diagnosis of lung and pleural diseases, with a positive rate of 50-70% of specimens and a diagnostic accuracy rate of 98%, but its adverse effects and complications are nearly 40%, mainly pneumothorax and hemoptysis and infection, etc. Therefore, clinical development is not popular enough, in recent years, the progress of medical technology and the development of medical equipment, CT-guided percutaneous pulmonary puncture in clinical In recent years, medical technology and medical equipment development, CT-guided percutaneous lung puncture in the clinical application has improved.
I. Commonly used equipment
Biopsy gun, 14-18G, length 10-15cm
Cutting needle, 16-20G, length 15-20cn
Biopsy needle, 16-20G, length 15-20cm
Coaxial positioning needle, 12-16G, length 10-15cm
Treatment Needle 18-20
Table setter: homemade
II. Applicable objects
(A) Application to intrapulmonary lesions
Intrapulmonary masses
Intrapulmonary nodular lesions
Diffuse lesions in the lung
Interstitial lung fibrosis
Tuberculosis cavity
Pulmonary abscess cavity
Tuberculosis globules, pulmonary
Tuberculosis cheese lesions
Lung cancer intervention
(II) Application of pleural lesions
Pleural tumors, masses
Pleural disease of unknown origin
Repeated massive pleural fluid growth
Restricted encapsulated effusion
Pustular pleura
Pleural tuberculoma
III. Contraindications
(1) Severe emphysema Those with cardiac insufficiency or myocardial infarction.
(2) Intrapulmonary vascular lesions, such as arteriovenous malformations and aneurysms, because they can lead to unpredictable bleeding complications, but are not absolute contraindications.
(3) Those with disorders of coagulation mechanism.
(4) Intercolonic pleural position (contraindicated only for 14-gauge needle), because the colon is extremely close to the angle of the rib diaphragm, and the puncture needle can easily pierce into the lumen of the colon during puncture.
