43. Surgical Approach
Zone-1: Access to Mediastinum
Zone-2 : Standard Carotid exposure
Zone-3: High carotid exposure:
Division of Posterior belly of digastric
Divide Veins that run with hypoglossal
Divide Ansa Cervicalis
Divide occipital branch of external carotid artery
Sublux the temporo-mandibular joint

49. Blunt thoracic aortic injury
80-90% die prior to hospital arrival
Cxr: Normal in 44%
Subtle abnormalities:
Widened mediastinum,
Left pleural effusion,
Loss of aorto-pulmonary window,
Depression of the left main stem bronchus,
Deviation of the trachea to the right,
Widening of the right paratracheal stripe
64. Introduction
Combined vascular and skeletal injury
Challenging combination
Rare: 0.2% of all injuries1
0.5%-1.7% of all fractures and dislocations2
10 fold increase in amputation rates
3 Fold increase in failed revascularisation rates
66. Hard Signs
Observed pulsatile bleeding
Arterial thrill by manual palpation
Bruit over or near the artery by auscultation
Signs of distal ischaemia
Visible expanding haematoma
67. Soft Signs
Significant haemorrhage on history
Decreased pulse compared to contra-lateral side
Bony injury
Proximity penetrating wound
Neurologic abnormality

84. Limb Salvage scoring Systems
Predictive Salvage Index (PSI) - HOWE 1987
MESS Mangled Extremity Severity Score
NISSSA Nerve Injury, Ischemia, Soft-Tissue, Skeletal Injury, Shock, Age
score
Limb Salvage Index (LSI) - Russell 1991
85. Risk Factors for Limb Loss/ Severe Dysfunction
Patient
• Shock and life-threatening associated injuries
• Elderly with medical co-morbidity
Vascular
• Prolonged ischemia (> 6-12 hours)
• Below-knee arterial injury
Injury
• Neurotemesis 2 or more extremity nerves
• Extensive soft tissue loss
• Crush injury
• Multiple fractures
• Severe contamination
• Patient preference (cultural sensitivities)
