Abstract
An 80-year-old man was admitted with an L5 compression fracture, L4/5 spondylolisthesis, and L5 radiculopathy and underwent a TLIF procedure. Refractory hypotension occurred, though it indicated a possible great vessel injury with vasopressor and fluid infusion. Emergent intraoperative angiography was performed, which showed extravasation at the right common iliac artery. Resuscitative endovascular balloon occlusion of the aorta followed by right common iliac artery stenting was successfully performed to arrest the bleeding. The iatrogenic right common iliac artery laceration was complicated with abdomen compartment syndrome and acute kidney injury. The patient received supportive care, including continuous venovenous hemofiltration (CVVH) for a week, after which the patient's condition improved. The patient did not have any residual complications at the one-month follow-up. Great vessel injury during the TLIF procedure is rare but fatal. Refractory hypotension is indicative of a great vessel injury. Endovascular intervention is a fast and promising method to diagnose and treat arterial injury.
