Iliac Artery Injury During Lumbar Disc Hernia Surgery

Background: Vascular injury complications during lumbar discectomy are rare but potentially life-threatening. Therefore, an early diagnosis and effective treatment management is required for these complications. Case Description: A 50-year-old female patient was admitted to our outpatient clinic with severe back and right leg pain. She underwent surgery for right L4-5 extruded disc herniation with general anesthesia. Sudden arterial hemorrhage occurred during discectomy performed with straight disc forceps and was controlled using hemostatic materials, with no significant decrease in blood pressure. However, the patient became hypotensive near the end of the operation. The incision was quickly closed, and she was turned to supine position. Emergency abdominal ultrasound, computed tomography, and computed tomography angiography revealed an injury of the left main iliac artery, which was repaired by endovascular stenting. Laparotomy and Bogota bag were applied because of increased intrabdominal pressure at 3 hours postoperative. In addition, a retroperitoneal catheter was placed into the area of the right retroperitoneal hematoma on the first postoperative day. Tissue plasminogen activator was administered through the catheter. On postoperative day 3, the Bogota bag was removed, and the abdomen was closed. The patient was discharged without neurodeficit on day 27. Her abdominal fascial defect was closed with a synthetic graft after 5 months. Conclusions: Although lumbar discectomy is one of the most commonly performed neurosurgical procedures, the routine rules of discectomy should not be neglected. Early detection and a multidisciplinary approach can help prevent mortality in the event of vascular injury.
