Pulmonary isolation resection

During embryonic development, part of the lung tissue is isolated from normal lung tissue to form pulmonary isolation. The isolated lung tissue is enclosed in the same visceral pleura as the normal lobes and is called intralobular pulmonary isolation. The isolated lung tissue has its own independent visceral pleura, which is called extra-leaf lung isolation. A few lung isolations are not compatible with normal lung leaves. Most lung isolations communicate with normal lungs through Kohn and/or bronchioles, but No respiratory function, no charcoal or a very small amount of charcoal. The columnar ciliated epithelium is visible under the microscope, with an irregular bronchial-like structure containing mucus. There are abnormal vascular systems regardless of intralobular or leafy appearance. Arterial supply can come from the thoracic aorta, the abdominal aorta and its branches, and venous return to the normal pulmonary vein is the most common type of intralobular pulmonary isolation. The leaf shape can be supplied by the body artery and the body vein is refluxed. Very few are provided by dual arterial blood supply and/or double vein drainage. In some cases, there is no arterial blood supply or venous drainage, and only local small blood vessels supply blood. About 14% of lung isolation also incorporate other abnormalities. Lung sequestration is mostly intralobular. Although intralobular pulmonary isolation may involve only one segment of the lung, lobectomy is often required because of inflammation and anatomical difficulties in the lung segment. Treatment of diseases: pulmonary isolation Indication 1. People with symptoms. 2. The patient is asymptomatic, but the intrapulmonary shadow is difficult to distinguish from diseases requiring lung cancer such as lung cancer and pulmonary cysts. Surgical procedure 1. The standard posterolateral incision is generally used to open the chest. The affected lung leaves often have an inflammatory reaction accompanied by local lymphadenopathy. 2. Show left lung lobe leaf type lung isolation. The collapsed left lower lobe is retracted forward, and the adventitia of the descending aorta is dissected, and the abnormal blood vessels that are emitted to the isolated lung are dissected and separated. Carefully separate from the diaphragm, and sometimes there may be several abnormal arteries that pass through the diaphragm to separate the lung tissue for blood supply. These blood vessels must be ligated and sewed before cutting. 3. After the abnormal blood vessels that have been sent to the isolated lungs are dissected, ligated, and cut, the oblique cracks are dissected. The pulmonary artery and vein were dissected, ligated, sutured and severed according to the usual steps of lobectomy. The bronchi is then treated. 3. After the abnormal blood vessels that have been sent to the isolated lungs are dissected, ligated, and cut, the oblique cracks are dissected. The pulmonary artery and vein were dissected, ligated, sutured and severed according to the usual steps of lobectomy. The bronchi is then treated. 4. The right lesion should be behind the heart, the mediastinal pleura is cut outside the inferior vena cava, and the abnormal artery is dissected in front of the esophagus. As with the left side, there may be one or more abnormal arteries that pass through the diaphragm to supply blood to the isolated lung tissue. After anatomical separation, ligation, and cutting off all abnormal blood vessels, the lobectomy was performed in the normal order. 5. Exogenous lung isolation can only be used to remove lung tissue.
