Major vascular traumatic injuries have a higher pre-hospital and in-hospital mortality rate. The different mechanisms of injury and anatomy of the aorta and inferior vena cava (IVC) make the management a constant challenge to surgeons and clinicians. Blunt traumatic aortic injury (BTAI) can occur at the thoracic or abdominal level, each of which possesses different considerations. Blunt traumatic inferior vena cava injury (BTIVCI) also has important diagnostic challenges since the lesion may not be as evident in the IVC as compared to the aorta, possibly due to lower caval pressures or the ability to self-tamponade from adjacent structures. Endovascular management has significantly increased in the past years, and despite an improvement in mortality, the approach to aortic and IVC injuries is not well standardized. Diagnostic imaging helps to classify the extent of the lesions and guide towards the best therapeutic options for each case. Conservative management, in some cases, has shown to reduce mortality, and close follow-up has proven good outcomes. Future research will provide more evidence to determine the best approach to BTAI and BTIVCI for better long-term outcomes. This article aims to provide an updated review of the current literature regarding diagnosis, classification, and management of BTAI and BTIVCI.
