头颈部旋转DSA技术探讨

Investigation on the technique of rotational DSA in head and neck

目的探讨旋转ＤＳＡ技术在头颈部的应用。方法使用ＳＩＥＭＥＮＳＭｕｌｔｉｓｔａｒＴ．Ｏ．Ｐ数字减影血管造影系统，对疑有血管病变的４２例患者首先分别进行头颈部常规正侧位ＤＳＡ检查，而后选择合适的技术参数，对其中１７例进行旋转ＤＳＡ检查。结果所有１７例患者病变血管的位置和大小清晰可见，１４例病变血管的供血和分支动脉避开造影剂的重叠。结论旋转ＤＳＡ技术是对常规ＤＳＡ的重要补充，对头颈部血管病变的诊断和治疗有很大价值。

Objective To investigate the application of rotational DSA in head and neck. Methods At first, the convenional anteroposterior view and lateral view of DSA were taken separately using SIEMENS Multistar T.O.P DSA system in 42 patients with suspected abnormal vessels followed by rotational DSA in 17 cases with optimum technical parameters. Results The localization and size of abnormal vessels were clearly visualized in all 17 cases, with the branches and feeding arteries of the abnormal vessels can be shown clearly without contrast medium overlapping. Conclusions Rotational DSA is an important supplement to the conventional DSA, providing great value in diagnosing and treating of blood vessel in head and neck.
