左右肘静脉注射对比剂对高血压患者CT增强效果的影响

Different Quality of Enhanced CT Image by Right or Left Side Ulnar Vein Injection in Hypertension Patients

目的对比有无高血压患者在行头颈部CT增强检查时,选择经左或右肘静脉注射对比剂时颈静脉逆流的发生率,探讨其中差异的影响因素.方法对531例无颈部及上纵膈占位性病变患者按照对比随机分组法,根据有无高血压进行分组,并随机选择左、右肘静脉注射对比剂行头颈部CT增强检查,记录颈部静脉逆流情况,对比有无高血压所致颈静脉逆流发生率的关系.结果选择左肘静脉注射对比剂产生颈部静脉逆流发生率较选择右肘静脉侧高,且与高血压有明显关系.结论在高血压患者中选择以右肘静脉注射对比剂,在头颈部CT增强扫描时可以明显减少颈部静脉逆流的发生.

Objective To explore the different infulencing factors for the incidence rate of jugular vein reverse current by comparing with hypertension patients and controls after use left or right side ulnar vein injection. Methods According to blood pressure, 531 patients without space occupying disease of neck and mediastinum were randomly derided into 2 groups： hypertension patients group and controls group. Each patients was performed CT enhanced examination with left or right side ulnar vein injection, and the incidence rate of jugular vein reverse current was recorded, in order to compare the incidence rate of vein reverse current between hypertension patients and controls. Result The incidence rate of jugular vein reverse current had more preferential in left side ulnar vein injection than right side injection, and it was obviously associated with blood pressure. Conclusion Using left side ulnar vein injection, the incidence rate of jugular vein reverse current will be reduced significantly in hypertension patients underging CT enhance examination.
