Stent graft placement for traumatic lumbar artery injury in which coil embolization is not feasible

Lumber artery injuries are anatomically difficult to treat surgically, and coil embolization is a first-line treatment option for them. In some cases, however, there is not enough space for coil embolization, for which stent graft placement can be an alternative therapy. We report a case of traumatic lumbar artery injury in which stent graft placement was performed due to lack of space for coil embolization.

Thoracic aortic and great vessel trauma and its management

Interventional radiologists (IRs) now play a major role in the management of thoracic aortic and great vessel trauma. The recent availability of a wide range of stent grafts able to treat vessels from 3 to 46 mm in diameter is clearly a significant contributor to this change. Stent grafts can now treat the majority of incomplete aortic injuries with much lower morbidity and mortality than open surgery. Short- to medium-term follow-up is encouraging, but the long-term durability is unknown, and close monitoring of these patients must continue. In great vessel trauma, stent grafts are a useful adjunct to balloon tamponade, embolization, and bare stents. As a result, a wide range of head neck and upper limb vascular injuries can be managed with less local trauma, blood loss, and physiological stress. The increased involvement of IR in the management of vascular trauma is not simply the result of technological advances. IRs have increasingly made themselves available to carry out these emergency procedures. IRs should assist in the development of trauma protocols and management algorithms that involve endovascular expertise early in the assessment of the major trauma patient.
