Types of pleura

Visceral pleura

Parietal pleura

1

Adheres to ALL surface of the lung

Reflected at the root of the lung & continues as parietal pleura

Visceral pleura

2

Adheres to crest wall, diaphragm & pericardial sac

Parietal pleura

3

Associated with the internal surface of sternum, corporal cartilages, ribs & sides of the thoracic vertebrae

Costal

4

Forms the pulmonary ligament (inferior to the root of the lung) which supports the lung

Mediastinal

5

Associated with root of the neck

Cervical

6

Parietal pleura has

Costal

Mediastinal

Diaphragmatic

Cervical

7

R & L costodiaphragmatic recesses
- normally sharp in PA radiograph
- blunted angle --> pathology of pleural space (excess fluid, blood, tumor, scar tissue)

R & L costomediastinal recesses
- slit-like

Pleural recesses

8

Lung base

Midclavicular line: 6th rib

Midaxillary line: 8th rib

Paravertebral line: 10th rib

9

Pleural base

Midclavicular line: 8th rib

Midaxillary line: 10th rib

Paravertebral line: 12th rib

10

Visceral pleura only --> no pain

Parietal pleura --> sharp local pain & referred pain to thoracic wall (intercostal nerve) & root of the neck (phrenic nerve C3-5)

Pleuritis

11

Most serious pleural neoplasm

Asbestos

Asbestos exposure

Malignant mesothelioma

12

Ruptured bleb (bulla) --> loss of neg

Intrapleural pressure --> collapsed lung

SSX: chest pain, cough, dyspnea

Spontaneous pneumothorax

13

Pleural cavity is opened to outside atmosphere

On inspiration --> air is sucked into the pleural cavity--> lung collapses

Causes: knife wound, thoracocentesis, transthoracic lung biopsy, mechanical ventilation, central line insertion

Open pneumothorax

14

Inspired air can't leave the pleural cavity on expiration (check valve mechanism) --> collapsed lung on wound side, compressed lung on the opposite side

SSX: absent breath sounds, chest pain, dyspnea, hypotension (mediastinal shift compresses SVC & IVC

Tension pneumothorax
