Pleurisy Paramediastinal

Paramediastinum (pleura mediastinum) is irritation or inflammation of the mediastinum. The pleura is left and right, and the pleura is divided into mediastinal pleura and costal pleura. The pleural pleura has septa that divide the pleural cavity into 2/3 large and 1/3 small. Divided into diaphragmatic and mediastinal halves. The mediastinal half can pass into the posterior part of the pleura of the diaphragm and the costal part. Half of the pleura, divided by the connecting isthmus, can become a cardiac pedicle, that is, connect to the superior vena cava. The junction of both pleurae forms the costal and diaphragmatic junction.

The pleurae can change into a simpler circle shape. There are three main round shapes known - the Garland triangle, the trapezoidal shape (deep pleura) and the semicircular angle (pyramidal angle).

The shape of a triangle has 3 angles, one acute (front) and 2 obtuse - lateral (large angle at the top). Medially, the angles are supplied by the middle lobe of the pulmonary artery. The pressure in this angle is reduced relative to the pneumothorax. The lower parts of the transverse and vertical diaphragms are attached to the middle lobe. The lateral upper corner has the upper left and lower right legs of the heart. The lower position of the right middle respiratory opening (lower indented). There is a posterior pleural and anterior subclavicular region. They originate from the venous flattened veins of the superior and inferodistal junction. Bitch
