Abstract
Purpose Traumatic thoraco-lumbar spine fracture spine with a concomitant blunt aortic injury is uncommon but potentially
a fatal association. Our aim was to clarify: morphology of spinal fractures related to vascular damages and vice versa, diag-
nostic procedures and decision-making process for the best treatment options for spine and vessels.
Methods We enrolled 42 cases culled from the literature and fve personal ones, reviewing in detail by AO Spine Classifca-
tion, Society of Vascular Surgery classifcation and Abbreviated Injury Scale for neurological evaluation.
Results Most fractures were at T11–L2 (29 cases; 62%) and type C (17; 70%). 17 (38%) were neurological. Most common
vascular damage was the rupture (20; 43%), followed by intimal tear (13; 28%) and pseudoaneurysm (9; 19%). Vascular
injury often required open or endovascular repair before spinal fxation. Distraction developed aortic intimal damage until
rupture, while fexion–distraction lumbar artery pseudoaneurysm and rotation–torsion full laceration of collateral branches.
CT and angio-CT were investigations of choice, followed by angiography. Neurological condition remained unchanged in
28 cases (90%). Overall mortality was 30%, but it was higher in AIS A.
Conclusion Relationship between thoraco-lumbar fracture and vascular lesion is rare, but potentially fatal. Comprehension of
spinal biomechanics and vascular damages could be crucial to avoid poor results or decrease mortality. Frequently, traction of
the aorta and its vessels is realized by C-dislocated fractures. CT and angio-CT are recommended. Spine stabilization should
always follow the vascular repair. Early severe defcits worse the prognosis related to neurological recovery and survival.

1. Traumac thoraco-lumbar spine fracture spine with a concomitant blunt
aorc injury is uncommon but potenally a fatal associaon.
2. C-fracture in flexion-distracon, with dislocaon and/or rotaon, affecng
vicms of traffic accidents or high-energy traumazed paents, may be
related to abdominal aorta injury or laceraon of its collateral branches due
to their common damaging biomechanics.
3. Early and postoperave mortality is high, as greater as more severe is the
inial neurological status. However, prompt recognion, classificaon and
treatment of the vertebro-vascular damage can likely reduce this fatal event.

Introduction
Blunt vascular injuries of the aorta and/or its collateral
branches (blunt traumatic aortic injury or BTAI) associated
with thoraco-lumbar spine fractures are rare [1, 2]. Their
occurrence may be asymptomatic or very serious and deadly,
with mortality rate of 85–90% during vascular full laceration
