PURPOSE
To investigate changes in blood pressure during intracarotid injection of contrast material.
METHODS
Two catheters were inserted into the ipsilateral common carotid artery of dogs. The proximal catheter was used for injection of contrast material and the other was positioned distally to monitor blood pressure.
RESULTS
Distal intracarotid pressure rose significantly during injection of contrast material at all rates (5, 7, and 10 mL/s) and at all doses (0.2, 0.5, 0.7, and 1.0 mL/kg). In addition, these blood pressure elevations were shown to be correlated with injection rates and doses. Even when the pressure-monitoring coaxial catheter was advanced into smaller arteries, no decline in the impact of injection was observed.
CONCLUSION
Intracarotid injection of contrast material causes a temporal elevation of cerebral blood pressure in dogs.
目的
研究颈动脉内注射造影剂期间血压的变化。
方法
将两根导管插入犬的同侧颈总动脉。近端导管用于注射造影剂，另一根置于远端以监测血压。
结果
在所有注射速率（5、7和10 mL/s）和所有剂量（0.2、0.5、0.7和1.0 mL/kg）下注射造影剂时，颈动脉远端压力均显著升高。此外，这些血压升高与注射速率和剂量相关。即使将压力监测同轴导管推进到较小的动脉中，也未观察到注射影响的下降。
结论
颈动脉内注射造影剂会导致犬脑血压暂时升高。
