Diagnosis and Treatment of Thoracic Conditions: A Comprehensive Review
I- Dx and T of Spontaneous Pnthorax:
^DX :
I- Dyspnea, pleuritic chest
Pain / ↓ Breath Sounds/Hyperesonance!
Pain / ↓ Breath Sounds/Hyperesonance!
II-XRay on Inspiration:
-Radiolucent air & absence of MAaking between
a shrunken lobe or lung
&the parietal pleura are diagnositc of Pneumothorax!
-Tracheal deviation ,
III- Pnthroax Defined:% of empty hemithorax
^^Tension Pn thorax :
if there is suden & unexplained :
-hypotension
-Dyspnea
-+ve Pressure ventilation
^^Tx:
I-”TENSION Pn TRX=Needle Decompresion
– ER —-> cannot wait for XRay
– Needle —–> 2nd IC space at mid-clavicular level!
II-‘1o Spont Pnthorax”=Catheter Aspiration
-Small bore IV —-> 2nd IC space ,mid lcaviular
-Air is withdawn from pleural space
-Process is repeated until Lung Re-expands or 4 L of air remvoed
III-”2nd & Traumatic Pnthorax”=Tube thoraccostomy:
-1/2 HEmotact/ Kelly Clamps
-Inserted Tube—-> 4th IC space , midaxillary line
-Using advanging Hemosat or kelly lamp the Pleura is dissected,
pleura is then pergorated
-clamp is inseeed through the tract and directly apical to Pnthoax
IV- Thoracosoy:
-Rigid telescope & insturment inserted into the pleiral space ,
through the trocar under local anasthesia
-1/2 tubes are left in the pleural space
V- VATS (Video assisted thoracic surgery):
-Under general ansthesia
– operated side should be isolated & its bronchial tree exposed
to outside atmopsere
-VATS beigns with insertion of a trocar camera and exploraton fo hemithrax later
-Principles of Surgery is :Resecting blebs, nbullae,
Obliteration of pleural space
(2)*** Surgical Approach in Tx of pleural empysema : irrigatie -aspirativ drainage ….:
Blood in pleura Sac
Primary Pleural empyema |
– bacterial contamination of pleural space due to chest Trauma |
Secondary pleural empyema |
-Direct contamination from organs adjacent to pleural surface -direct bacteria spread across the visceral or parietal pleura 90 |
^^Bacterial Classication:
-non speicif/pyogenic
-Specific
-Mixed
Complicated, Lined with bronchopleual/alvoelar fistula
Non complicated
^^Surgical proceudre foe empyema:
I-Irrigation & Drainage:– Acute & chronic Non compicated Pleural empyema to facilitation elimation of peural content-Caution is adviced in presence of Bronchopleural Fistula de to possible aspiration with washing Fluid |
II-Decortication and pleuretony -In Case of chronic pleural empyema! -Decortication:-—–>removal of constricting Peel from the Lung -Pleurectomy—->excision of thickened parietal pleura -Goal: of these procedure is Lungreexpansion |
III-Pleurostoma:-in patient whose lung can re-expand and his condition is stable-Pulmonary Decortication alternative-Involves resecting 6-20 cm of 2-4 ribs —–>creating large defect in patient chest |
(3) *** Classification of Chest Trauma :
Penetrating ChT(Isolated /Polytrauma) |
-Superficial Wound (Chest Wall) -Involving the parietal pleura & intrathoracic viscera |
Blunt ChT(Isolated/Polytrauma) |
-Non complicated chest wall injury ( Contusion / hematoma/ Chest bone fracture) -Complicated Facture of chest Bone -Blunt Injuries of intrathoracic viscera (Pleruopulmonary/CVS.Rupture of esophagus/Diaphragm rupture) |
(4) *** Syndrome of Chest Trauma :
^^Gaseous Syndrome (air —-> into soft tissue of Chest Wall ,mediastinum & Pleural Space) I-Subcutaneous EmphysemaII-Pneumothorax-Air in pleural cavity -minimal= no lung compression -Moderate=Lung collapse -Total= compression and displacement of Mediastinum III-Pneumomediastinum-Maybe due to esophageal perforation -Degree caries with location -Air reaches Visceral pleura IV- Intersitial Pulmonary emphysema-Air penetrates into pulmonary parenchyma dissecting into along the vessel and small bronchi -blebs occur when air reaches Pleura |
^^Open Pneumothorax:-Penetrating Wound /Defect in chest wall -Result : intrapleural = atm |
^^Flail chest:-2 pint fracture of Several Ribs or sternum -paradoxical movement of segment of chest -Alters ventilation and result in hypoxemia or Hypercapnia |
^^Traumatic Asphyxia-Cause: Crush injury or sidden compression -Rise n intrathoacic pressre,intrathoracic Venous Pressure , stopping or reversing venous Drainage(head and neck) |
^^Pulmonary contusion & hematoma: |
^^Hemothroax (Blood accumilation in pleural cavity ) |

-Sometimes needs Esophageal replacement
5- Diaphragmatic Injury :
-Laparscopy & thoracoscopy can be used in Dx & Tx
-injuries require Heavy , non absorbable sutures, mesh closure
6- thoracic Great Vessel Injury :
-emergency thoracotomy in case of hemodynamic deterioration !
7- Cardiac injury :

(8)***Aspirative Punture of pleural cavity :Indication , technique, possible complication
^^Thoracentesis:—-> puncture through chest wall to aspirate pleural Fluid |
^^Indication :-determination of pleural effusion etiology(Dx)-relieve dyapnea caused by pleural effusion(Tx)-Pleurodesis |
^^Technique:-Find the location of Fluid using physical exam , or imaging-Patient is sitting upright-leaning slightly forward with arms supported-In sterile condition 1-2% lidocain is injected with 25-gauge needle-then larger needle with anasethetic is inserted at upper border of the rib one intercostal space below the Fluid level-needle is advanced with periodic aspiration-Anathetic is progressively injected deeper -Needle is advanced beyond parietal pleura until pleural fluid is aspirated!-thoracentses needle is passed thrugh skin & Subcutanous tissue Along the upper border of the Rib into effusion -the catheter is inserted through the needle, the needle is withdrawn to decrease the Risk on Pn thorax |
^^ Complication :Pnthorax-Heoptysis-Hemothorax -Vasovagal syncope |
(9) ***Methods of Pleural Cavity Drainage, indication ,
‘Tube Thoractomy:-Tube Into Pleural Sapce-Promote air or Fluid evacuation-Lung Re-exanapsion-Restoration of intrapleural -ve pressure |

^Gx:-caused due to placement of a tracheostomy Tube-injury of trachea-Chronic inflammation |
Px: inspiratory stridor & dyspnea |
^^Dx: -CT -CT-3D image to ID the location of Stricture& determine size -Bronchoscopy |
Tx:-”Resection of stenosedtracheal part” is the Procedure of choice -we use tracheostomy to bypass intubation |
(12) ***Mediastinal Disease^^^Mediastinal Tumours
Dx:1-CXR- to ID abnormality2-CT :Can asses the mediastinal widening , Diff Cystic & Solid MassesLocalize Masses wrt other structures3-Biopsy & distopathology :-Tisse confirmation prior to therpy -Fine needle percutanous biopsy to excisional biopsy |
^^TX :-depends on location h& histological Type of Tumor-All Tumours & Mases should be surgically removed-Non resectable malignant tumours should undergo Chemo therapy & or Radiotherapy! |
^^ Bacterial Medistinitis:
^^Dx: -CF : chest pain ,dyaphgia , Cervical & mediastinum emphysema-CXR : normal ( early) —–> Widnd mediatinal tumour (Later) -Contrast Esophagogtraphy—–> esiphageal perforation is suspected |
^^ Surgical Tx:-early & aggressively-In case of Esopahgeal Perforation do Surgery directly! ( closure of esophageal wall defect / Debridment irrigation & drainage) -Ax therpay after Surgery |
