Abstract:
Objective:To investigate the value of 64-slice spiral computed tomography (64SCT) in preoperative evaluation of spinal vascular intervention.Methods: Seventeen patients with spinal vascular malformations(SVM) scheduled for spinal vascular interventional therapy in our hospital between January 2012-December 2014 were collected, all received 64-detector spiral CT angiography (64-MDCTA) before surgery, image postprocessing technologies such as volume rendering (VR), maximum intensity projection(MIP) and multiplanar reconstruction(MPR) were applied to conduct three-dimensional reconstruction, the traveling case of spinal cord feeding artery was analyzed and were compared with DSA test results.Results: All of the 17 patients clearly showed the abnormality of spinal cord blood vessels and lesions scope, the SVM classification and lesions scope were exactly the same as that of DSA and intraoperative performance, the coincidence rate was 100%;1 case of patient was not shown fistula, the rest of the patients clearly shown the draining veins around the spinal cord, open position and flow tendency of radiculomedullary artery, the coincidence rates were 100.00%, 94.12%%, 100.00%.Conclusion: 64-MDCTA is important for SVM patients to preoperative evaluation of spinal vascular intervention, for it can fully and accurately reflect the open position and flow tendency of radiculomedullary artery, spatial relationship with the surrounding vessels, spinal cord and vertebral situation, should be widely applied.
