Operation method and procedure of renal arteriography

1. Using Seldinger technique, puncture femoral artery or brachial artery and intubate.

2. Abdominal aortography was performed first, then selective renal arteriography was performed, and superselective renal segmental arteriography was performed when necessary. In selective angiography, the catheter should not be too deep to avoid the illusion of kidney deficiency.

3. The injection parameters include the dose of contrast agent for renal angiography 10~ 15ml/ time, and the injection flow rate is 5 ~ 7ml/s; The dosage of contrast agent for renal segmental arteriography is 4~6ml/ time, and the injection flow rate is 2 ~ 3 ml/s.

4. The shooting position is positive, and if necessary, it is inclined. The image intensifier is inclined to the same side by 7 ~ 15.

5. The imaging procedure is 3~6 frames per second, and the injection delay is 0.5s. Breath-holding exposure to microvascular phase and early venous phase.

6. After angiography, pull out the catheter, apply local pressure 10 ~ 15 minutes, and then apply pressure to bandage.

7. Photographers should carefully fill in the relevant items and technical parameters of the inspection application form and sign it.
