The procedure is usually performed when the lung is covered by a thick, inelastic pleural peel restricting lung expansion. In a non-medical aspect, decortication is the removal of the bark, husk, or outer layer, or peel of an object. [1] It may also be done in the treatment of chronic laryngitis.
A lung biopsy is an interventional procedure performed to diagnose lung pathology by obtaining a small piece of lung which is examined under a microscope. [ 1 ] [ 2 ] Beyond microscopic examination for cellular morphology and architecture, special stains and cultures can be performed on the tissue obtained.
A variety of sizes of needles can collect tissue in the lumen (core biopsy). Smaller diameter needles collect cells and cell clusters, fine needle aspiration biopsy. [6] Pathologic examination of a biopsy can determine whether a lesion is benign or malignant, and can help differentiate between different types of cancer. In contrast to a biopsy ...
To confirm the diagnosis, a doctor may perform a lung biopsy using a bronchoscope. Many times, a larger specimen is needed and must be removed surgically. Plain chest radiography shows normal lung volumes, with characteristic patchy unilateral or bilateral consolidation. Small nodular opacities occur in up to 50% of patients and large nodules ...
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.

In some lung diseases, especially emphysema, it is possible for abnormal lung areas such as bullae (large air-filled sacs) to have the same appearance as a pneumothorax on chest X-ray, and it may not be safe to apply any treatment before the distinction is made and before the exact location and size of the pneumothorax is determined. [15]
Specimen of lung tissue (transbronchial biopsy) may be sampled using a real-time X-ray (fluoroscopy) or an electromagnetic tracking system. [12] Flexible bronchoscopy can also be performed on intubated patients, such as patients in intensive care. In this case, the instrument is inserted through an adapter connected to the tracheal tube.
Despite the medical advances of detection, diagnosis and treatment methods throughout the past 50 years, lung cancer causes more deaths than any other cancer in both men and women. [5] Currently, lung cancer is the most common form of cancer diagnosed in the United States and a major cause of death, accounting for 14% of all cancers. [6]
