摘　　要：目的评价DSA三维重建技术在椎体成形术中的应用价值。方法重建32例共48个胸椎(T_1～T_6),其中骨质疏松所致椎体压缩性骨折10例,转移瘤21例,骨髓瘤1例,在椎体成形术术前、进针过程中及注入骨水泥后分别行三维旋转采集并作三维重建,术前观察椎弓根、椎体形态及骨皮质的完整程度,术中观察进针针尖的方向和位置,术后观察骨水泥在椎体内的分布情况以及骨水泥的渗漏情况。结果术后椎体三维重建发现骨水泥渗漏8处(其中椎旁及椎间盘5处,椎管内3处)。所有病例均未引起严重的并发症。结论 DSA三维重建技术在上段胸椎椎体成形术中是预防骨水泥渗漏的一种切实可行的方法。Objective To evaluate the apphcation value of DSA three-dimensional reconstruction in percutaneous vertebroplasty （PVP）. Methods There were 32 patients with 48 upper thoracic vertebrae （T1-T6）. Of which, 10 were compression fracture of vertabral body, 21 were metastatic tumors, 1 was myeloma. Three-dimensional rotary acquisition and three-dimensional reconstruction were carried out before operation, in the course of inserting the needles and after injecting the bone cement. Before the operation, the shape of pedicle and centrum and integrity of bone cortex were observed. During the operation, the direction and location of the needles were all observed. While the distribution of the bone cement in vertebral bodies and leakage of bone cement were observed after the operation. Results By three-dimensional reconstruction after the operation, leakage of bone cement was found in 8 thoracic vertebrae, 5 of which were leaked into paravertebral space and intervertebral disc, 3 of which were leaked into the spinal canal. There were no severe complications in all patients. Conclusion Three-dimensional reconstruction of vertebral bodies is a practical way to prevent leakage of bone cement during percutaneous vertebroplasty （PVP） of upper thoracic vertebra.
