Background: Iatrogenic vascular injury during lumbar discectomy is a rare but serious and life threatening complication. The pituitary rongeur is the usual cause of injury during the disc surgery. A deep bite can injure the major vessels, especially the abdominal aorta or the common iliac arteries. Case Presentation: We present a 33-year-old female patient with complaints of continuous abdominal pain and difficulty in walking. Her complaints began a couple of days before her admittance to our clinic. In the medical history, the patient had undergone a lumbar discectomy operation due to L4-L5 disc hernia 4 months ago. Her follow-up physical examinations were uneventfully in the first and third month of the lumbar disc surgery. The patient had no any chronic diseases in her medical history. Computed tomographical angiography revealed a 57 × 42 mm pseudoaneurysm formation from the abdominal aorta arising closely from the abdominal aortic bifurcation level. A primary repair for the posterior abdominal aortic defect and a patchplasty for the aortotomy was performed. Conclusion: Clinician should suspect of vascular complications in terms of ongoing complaints, such as abdominal pain or a pulsatile mass in the abdominal region after lumbar disc surgery. In such cases, the clinical evaluation and imaging procedures must be done carefully.
Key words: Surgery complications, disc surgery, pseudoaneurysm, treatment.
