What do you think of coronary angiography

summary

Some time ago, my body was not very comfortable, so I went to the hospital for a coronary angiography operation. I believe many people don't know much about coronary angiography. Next, I'd like to share with you how to see coronary angiography.

What do you think of coronary angiography

First of all, the puncture needle will be inserted into the femoral artery of the lower extremity or the radial artery of the upper extremity, the special catheter will be sent retrogradely along the descending aorta to the root of the ascending aorta, and the catheter will be placed at the left and right coronary artery respectively. Then the contrast agent was injected, and the X-ray cine or tape recording was turned on at the same time. Soon, the doctor can clearly see the whole picture of the left and right coronary arteries and their branches on the display screen, so as to know whether there is stenosis in the coronary artery, and make a clear judgment on the location, scope, severity of the lesion, as well as the condition of the vessel wall.

Secondly, coronary angiography is to insert a special catheter through the femoral artery in the thigh or the radial artery in the upper limb into the coronary artery opening, selectively inject the contrast agent into the coronary artery, and record the development process, so as to judge whether the coronary artery has lesions.

Finally, anesthesia is used during coronary angiography to make people unconscious, so that they do not feel special pain.

matters needing attention

Before the operation of coronary angiography, we must check the liver function and renal function. During coronary angiography, we must not have too much emotional fluctuation, because it will affect the effect of coronary angiography.
