Beschreibung

Pleural diseases are frequently managed in primary care, but specialist knowledge is required to understand the full variety of presentations and available treatments in this rapidly developing field. ABC of Pleural Diseases is a brand new addition to the ABC Series which takes a unique approach to these conditions by dealing with them as a related group as well as in their individual manifestations.

The book provides a unique and comprehensive overview of pleural disease, beginning with the anatomy and physiology of the pleura. It then covers a wide range of specific conditions in greater detail, including pneumothorax, pleural effusions, pleural infections, as well as chapters on radiology and pathology. Full coverage is given of mesothelioma, the most common pleural cancer.

Written by a team of specialists, this reference guide to pleural diseases is a practical guide for General Practitioners, Junior Doctors, Specialist Nurses, Radiologists and all Healthcare Professionals working within chest medicine.

CHAPTER 1Anatomy and Physiology of the Pleura

John P. Corcoran and Najib M. Rahman

Oxford Centre for Respiratory Medicine, Churchill Hospital, Oxford, UK

OVERVIEW

The pleural space is a real rather than potential space, containing a small amount (<20 mL) of pleural fluid.

Mesothelial cells line the visceral and parietal pleura, with size and shape varying according to position. They are metabolically active and can perform a variety of functions.

The parietal pleura is innervated whereas the visceral pleura has no nerve supply (and hence does not produce pain in pathological conditions).

The pleural space is normally under negative pressure.

Pleural fluid is secreted from the systemic vessels of the parietal pleura, and is drained through lymphatic channels in the parietal pleura. The normal drainage capacity is very large compared to the secretion capacity.

The pleural cavity is a real rather than potential space, containing a thin layer of fluid and lined with a double‐layered membrane covering the thoracic cavity (parietal pleura) and outer lung surface (visceral pleura) whose precise purpose and structure are incompletely understood. The gaps in our knowledge are best illustrated by the unexplained anatomical variations among different mammals. In humans, the left and right pleural cavities are separated by the mediastinum, but in species as diverse as the mouse and bison there is a single pleural cavity, allowing free communication of fluid and air between right and left. The elephant has evolved to have no cavity at all – instead having loose connective tissue between the two pleural membranes. In time, it may be that describing how and why these differences have evolved will help us to understand the role the pleural cavity has in humans. This chapter focuses on the key features of human pleural anatomy and physiology.

Embryology

The human body contains three mesothelium‐lined cavities – two large (pleural, peritoneal) and one small (pericardial) – derived from a continuous mesodermal structure called the intra‐embryonic coelom as it is partitioned at 4–7 weeks’ gestation. Arising from a medially placed foregut structure that will ultimately form the mediastinum, primordial lung buds grow out into the laterally placed pericardio‐peritoneal canals, taking a layer of lining mesothelium that will become the visceral pleura in the process. As the lungs rapidly enlarge, they enclose the heart and widen the pericardio‐peritoneal canals to form the pleural cavities. These are separated from the pericardial space by the pleuro‐pericardial membranes, whilst the septum transversum (an early partial diaphragm) joins the pleuro‐peritoneal membranes to partition each pleural cavity from the peritoneal space. The mesothelium lining the pericardio‐peritoneal canals as they become the pleural cavities goes on to form the parietal pleura.

Macroscopic anatomy

The pleura is a double‐layered serous membrane overlying the inner surface of the thoracic cage (diaphragm, mediastinum and rib cage) and outer surface of the lung, with an estimated total area of 2000 cm2 in the average adult male. Between lies the pleural cavity, a sealed space maintained 10–20 micrometres across and filled with a thin layer of fluid to maintain apposition and provide lubrication during respiratory movement. The left and right pleural cavities are completely separated by the mediastinum.

The visceral pleura is tightly adherent to the entire lung surface, not only where it is in contact with chest wall, mediastinum and diaphragm, but also into the interlobar fissures. The parietal pleura is subdivided into four sections according to the associated intrathoracic structures: costal (overlying ribs, intercostal muscles, costal cartilage and sternum); cervical (extending above the first rib over the medial end of the clavicle); mediastinal; and diaphragmatic. Inferiorly, the parietal pleura mirrors the lower border of the thoracic cage but may extend beyond the costal margin, notably at the right lower sternal edge and posterior costovertebral junctions.
