Lung anastomoses stay in the body after surgery. Lung anastomosis is needed when performing lung surgery, such as resection of lung blisters and lung nodules. By placing the lung anastomosis and anastomosing the cut edges of the lung tissues, the anastomosis plays a role in reducing bleeding and avoiding air leakage from the lungs, and at present, most of the anastomoses are made of titanium alloy, and they are used for a long time, and have been used for decades of experience, so the patients usually don’t feel the discomfort. The lung anastomosis stays in the body and will not affect the subsequent examinations, such as lung CT, MRI, etc.; at the same time, it will not fall off under normal circumstances, and will remain in the body for life.
