| Summary: | Background: Polytrauma is understood as significant injuries, occurring at the same time, to two or more anatomical regions (the ISS regions) or organ systems, with at least one of the injuries considered as posing a threat to life. Trauma is the main cause of unexpected demise in individuals below the age of 44 years and represents a huge burden on society. Vascular injury is highly morbid; it can lead to rapid exsanguination and death, posing a threat to both life and the limb. Independent predictors of outcome include mechanism of injury, associated injuries, and time from injury to definitive care. The mechanisms of vascular injury in the setting of polytrauma are either blunt, penetrating or a combination of the two. Methods: Comprehensive literature review of current diagnostic approaches to traumatic vascular injury in the context of polytrauma. The factors influencing the diagnostic approach are highlighted. The focus is the epidemiology of vascular injury and diagnostic approaches to it in the context of polytrauma. Results: Traumatic vascular injuries are associated with limb loss or even death. They are characterised by multiple injuries, the dilemma of the diagnostic approach, timing of intervention and higher risk of limb loss or death. The systematic approach in terms of clinical diagnosis and imaging is crucial in order save life and preserve the limb. The various diagnostic tools to individualise the investigation are discussed. Conclusion: This paper highlights the significance of timely and appropriate use of diagnostic tools for traumatic vascular trauma to save life and to preserve the limb. The associated injury also plays a crucial role in deciding the imaging modalities. At times, more than one investigation may be required.
