颈内动脉虹吸部应用解剖与数字减影血管造影对照研究及应用

The correlation study of the applied anatomy of internal carotid artery with brain DSA.

目的 对 35具成人头颅颈内动脉虹吸部进行血管的走行方向、成角、开口方位的观察 ,与5 0例全脑数字减影血管造影 (DSA)对照分析 ,为指导颅内动脉插管提供解剖学依据。方法 甲醛固定成人头颅标本 35具 ;依次分离 ,充分暴露颈内动脉虹吸部 ,仔细观察和测量颈内动脉虹吸部 ;5 0例全脑血管DSA检查阴性的血管情况作参照分析。结果 颈内动脉虹吸部血管走行成角 ,可分为 3个角度和1个弯度 ,两侧差异无显著性 ,与DSA资料对照分析差异无显著性。结论 颈内动脉虹吸部血管走行角度及开口方向 ,对插管具有重要意义。

Objective To provide the exact anatomic basis for guidance of inserting catheter promptly.Methods Thirty five cases of adult crania were fixed by 10% liquor formaldehyde. In turn with precise discection of surrounding tissues and exposing carotid C 5～C 1 segments, paid attention to observe and measure vessel's trend, angulations, and direction of routes. Analysis of 50 cases of negative result of normal brain DSA is then taken as the basis for further application. Results Angulations of siphon were divided into 3 kinds of angulation and 1 characteristic curve but, the difference with the counter part is insignificant. Conclusions Mastering the applied anatomy of carotid could improve catheter maneuver and the rate of success.
