What harm does angiography have?

First of all, we need to make sure that there is not too much pain for brain angiography, but when injecting contrast agent, we may feel head pain or burning. When doing the examination, we must overcome psychological fear and tension, and relax to cooperate with the examination.

Before the examination, we need to do the contrast agent and anesthetic allergy test for the patient. If the patient has discomfort, we must respond to the doctor. Only the negative experimenter can do the contrast examination, and we also need to do the clotting time test. It is also worth noting that fasting is required 6 hours before the examination.

And after doing contrast examination, the patient should rest in bed, and closely observe the development of the disease and whether there is bleeding or hematoma in the puncture site.
