Lumbar Artery injury from which the Adamkiewicz Artery originated associated with Lumbar spine injury: successfully treated by transcatheter arterial embolization.
European spine journal : official publication of the European Spine Society the European Spinal Deformity Society and the European Section of the Cerv, 2015Co-Authors: Tomoaki Koakutsu, Toshimi Aizawa, Hironao Yuzawa, Eiji Itoi, Shigeki KushimotoAbstract:Lumbar Artery injury associated with Lumbar spine injury can be a cause of shock leading to life-threatening condition. The Adamkiewicz Artery often bifurcates from a Lumbar spine or an intercostal Artery at the thoracoLumbar junction, where spine injury most commonly occurs. However, in emergency transcatheter arterial embolization for Lumbar Artery injury, hemostasis has priority and blood supply to the Adamkiewicz Artery is not frequently confirmed. The aim of this report is to present the case of Lumbar spine injury with Lumbar Artery injury from which the Adamkiewicz Artery bifurcated. Retrospective description of a case. A 58-year-old man was pinned under about 300-kg steel container that fell on his back. He was transported to our hospital presented with hemorrhagic shock. Contrast-enhanced computed tomography demonstrated L1-2 flexion-distraction injury and the left psoas major muscle swelling with extravasation of contrast medium, which suspected Lumbar Artery injury. Emergency angiography demonstrated the bilateral 2nd Lumbar Artery injury. Likewise, the Adamkiewicz Artery originated from the distal part of the left 2nd Lumbar Artery. Fortunately, selective angiography of the left 1st Lumbar Artery depicted collateral circulation to the Adamkiewicz Artery. Embolization of the bilateral 2nd Lumbar Artery was performed and massive hemorrhage was controlled successfully without spinal cord ischemia. Close attention must be paid to Lumbar Artery injury in the management of patients with Lumbar spine injury. Once Lumbar Artery injury is found, transcatheter arterial embolization can be the choice of the treatment with careful attention to the Adamkiewicz Artery.

Management of Complicated Lumbar Artery Injury After Blunt Trauma
Annals of Emergency Medicine, 2011Co-Authors: Kuo-ching Yuan, Jen-feng Fang, Yon-cheong Wong, Huan-wu ChenAbstract:Study objective Lumbar Artery injury after blunt trauma is not frequently discussed. We review our experience with blunt Lumbar Artery injury management, especially alternative treatments in which embolization is not feasible. Methods We reviewed our trauma registry for 8 years 8 months. We sought all patients who sustained blunt torso trauma and had Lumbar Artery injury detected by angiography. Variables collected included demographic data, trauma mechanism, vital signs in triage, Injury Severity Score, associated injuries, computed tomography results, angiography results, embolizations, and outcome. Results Sixteen of the 3,436 patients in the trauma registry system had a blunt Lumbar Artery injury verified by angiography. For patients with Lumbar Artery injury, the mean Injury Severity Score was 38.6 (SD 12), and 10 (63%) of these 16 patients were in shock and 12 patients (75%) had closed head injuries. Angioembolization caused bleeding cessation in 11 patients but failed in 5 patients, who were treated conservatively. The overall mortality rate of patients with Lumbar Artery injury was 50%. Conclusion Lumbar Artery injury in multiply injured patients with blunt trauma leads to a high mortality rate, especially if accompanied by head injury. Embolization often stops bleeding, but, if embolization is not feasible, conservative treatment without retroperitoneal surgery can be successful.

transcatheter arterial embolization of traumatic Lumbar Artery injury experience in one institution
Journal of Radiological Science, 2011Co-Authors: Shengche Hung, Huan-wu Chen, Jen-feng Fang, Yon-cheong Wong, Lijen Wang, Beingchuan LinAbstract:Transcatheter arterial embolization has been well recognized and popular for the management of traumatic Lumbar Artery injury (TLAI). Current evidence regarding the management of TLAI is still based on case reports and a few small series of studies. The purpose of the study is to evaluate the efficacy and results of embolotherapy in the management of Lumbar Artery trauma in our hospital, a 3000-bed tertiary hospital in the Northern Taiwan.We retrospectively recruited all patients who underwent angiography and transcatheter arterial embolization (TAE) for Lumbar Artery injury from April 2004 to December 2008. Angiographic images and procedural reports were reviewed to assess immediate results. Trauma mechanism, associated trauma, injury severity score, clinical outcomes and post-embolization complications were obtained by chart review.Of seventeen patients with Lumbar Artery injury who underwent angiography, selective embolization was performed in fourteen patients. AII fourteen patients exhibited immediate angiographic success. The overall mortality was 36% (5/14). However, there was only one suspected TLAI-related death. Two patients had minor neurological complaints in the follow-up period. No patient exhibited major neurological deficits or soft tissue complications.Traumatic Lumbar arterial injury is an uncommon condition that requires a high index of clinical suspicion in the patients of retroperitoneal hemorrhage. According to the literature and our experience, TAE is a safe and effective method to achieve hemostasis.

Lumbar Artery pseudoaneurysm in a patient with inferior vena cava filter and history of strenuous physical exercise.
Journal of vascular surgery, 2013Co-Authors: Nikolaos S. Tsekouras, Ralph C. Whalen, Anthony J. ComerotaAbstract:Lumbar Artery pseudoaneurysms (LAPs) are a rare complication of inferior vena cava (IVC) filters. The few reports in the literature describe treatment of patients presenting with ruptured LAPs. This case report describes the successful management of a symptomatic LAP because of an IVC filter, which initially presented as a retroperitoneal hematoma resulting from Lumbar Artery laceration by a filter strut. We hypothesize that the strenuous abdominal exercises performed by the patient may have facilitated IVC penetration by the filter, leading to development of a retroperitoneal hematoma and subsequent LAP. This case suggests that patients with IVC filters should avoid strenuous exercise and underscores the importance of timely retrieval of nonpermanent IVC filters.

Lumbar Artery compression by the diaphragmatic crus: a new etiology for spinal cord ischemia.
Annals of neurology, 2000Co-Authors: André Rogopoulos, Daniel Benchimol, Ph. Paquis, M. H. Mahagne, A. BourgeonAbstract:We describe a new cause of spinal cord ischemia illustrated by two cases--compression by the diaphragmatic crus of a Lumbar Artery giving rise to a spinal Artery. The diagnosis has been established by dynamic spinal angiography, showing complete occlusion of the Lumbar Artery. Surgical section of the diaphragmatic crus prevents irreversible infarction.
