37) In supine patients, pleural air tends to collect in the non-dependent portion of the pleural space
, namely the anteromedial and subpulmonic recesses.
What accounts for the negative pressure within the pleural space
is the opposition of the elastic recoil of the lungs and that of the chest wall.
Malignant pleural effusion: accumulation of fluid in the pleural space
with malignant cells within it; may cause severe dyspnea, chest tightness, pleuritic pain, and cough
Moreover, blood oozing from the thorax wall will be collected in the pleural space
and as a consequence, there will be pressure on the lungs which will facilitate atelectasis.
A contrast-enhanced computed tomographic (CT) scan of the neck and chest showed cervical subcutaneous emphysema, pneumomediastinum, and multiple pockets of accumulated turbid fluid over the neck, superior mediastinum, and bilateral pleural spaces
It will be used in the management of patients with lung disease, predominantly involving the area between the lung and chest wall, called the pleural space
The potential space between the lungs and the inside of the chest cavity is called the pleural space
or pleural cavity.
Several attempts at thoracentesis have failed, however, suggesting that either there is very little fluid in the pleural space
or that it is inaccessible due to the large amount of tumor in the patient's chest.
Length-dependent retention of fibres in the pleural space
For example, as the lungs inflate and deflate, the serous fluid in the pleural space
enables the lungs to move freely against the chest wall throughout the respiratory cycle.
We believe that by excluding the transverse process from the image used for needle placement, one avoids the dropout deep to the transverse process at the critical point where needle placement close to the pleura, but not in the pleural space
, is so important.
23) Non-dependent crescentic lucency in the pleural space
is seen on CT (deep sulcus sign).
