[The Efficacy of CT angiography using the IVR-CT/angio system for surgical treatment of spinal hemangioblastoma].
We performed 3D-CT angiography (3D-CTA) with contrast injection to a feeding artery through a selectively introduced catheter into the intercostal artery in a patient with spinal hemangioblastoma. It revealed a relative three-dimensional (3D) anatomy between a tumor body, feeding arteries, draining veins, and surrounding vertebrae with superior resolution to 3D-CTA with intravenous contrast injection. This observation was used for preoperative planning facilitating tumor removal, through reconstructed 3D fly-through animation providing intraoperative identification and obliteration of feeding arteries. This examination was carried out without difficulty by utilizing IVR-CT/angio system (IVR: interventional radiology) which combines angiographic and CT equipment with a single fluoroscopy table, because it does not require a room-to-room transfer of the patient with the catheter left cannulated. DSA detection for any spinal lesions, neoplastic or vascular ones, is always better assisted by 3D-CTA with the IVR-CT/angio system (IVR-CTA).
