Abstract

Objective: To determine the efficacy of 64-slices computed tomography in the evaluation of anterior spinal anatomy in patients undergoing anterior lumbar spine surgery. Methods: Cross-sectional description study of 56 patients undergoing CT 64 slines of abdominal arrays with an image construction of the vascular anatomy at Viet Duc Hospital. Results: Of the 56 patients, 29 were female and 37 male, with a median age of 41,3 years. The common division in the artery is at the level of the L4 vertebral body, accounting for 42,8%, while the common division of the vein is at the level of the L45 disc, accounting for 57,1%. Distance from the included angle vertex of the iliac vascular space to the inferior boundary of L5 is 2.01 ± 1.06 and Distance between the left and right iliac vessels on the inferior boundary of L5 is 3.11 ± 2.14. The anatomic parameters of the iliac vascular space classifcation system, there were 19.6 of Type A, 40.4% of Type B, and 50% of Type C. Conclusion: MSCT 64 slide is highly valuable in evaluating anatomy, variants, arterial abnormalities, 3-host renal veins. It plays an important role in anterior lumbar spine surgery, helping surgeons plan ahead of surgery for the incision and prepare materials that can be needed during surgery for prompt actions.
