Abstract:
Objective To discuss the problems about needle path in the procedure of CT guided percutaneous biopsy of cervical spine, and to analyze different approaches related with different lesions. Method Seventy eight cases with cervical vertebral lesions underwent CT guided percutaneous biopsy. There were 45 males and 33 females, and the age ranged from 2 to 73 years. The lesions located in C1～7 involving all parts of cervical spine. Precise needle paths were designed according to different locations of lesions. Results Seventy one of 78 cases have definite histological diagnosis, and the accuracy of biopsy was 91%. The detailed approach pathways were as follows: the pathway between vertebral artery and carotid sheath; the pathway between carotid sheath and trachea; the pathway posterior to the vertebral artery and carotid sheath. Conclusion The main principles of needle paths are as follows: the pathway should be parallel to spinal cord so as to avoid injuring the cord; avoid large vessels and important structures and pass through the interspace of them.
