Angiography is an x-ray technique of viewing the blood vessels of heart after injecting with a radiopaque dye into the chambers or arteries leading to heart. This procedure is also used by the doctors to carefully examine the arteries in to rule out any blockage and analyse the blood flow and blood pressure in the heart. The procedure is also Angiogram
Before angiography, certain details and standard tests will be conducted:
Medication being taken, you might be asked to stop all medication one day prior to the procedure.
Blood tests to check the overall health
Before the procedure sedatives may be given and it is advised not to eat anything for few hours before the procedure.
The first and foremost local anesthesia in given
The next process involves insertion of an intravenous (IV) line into the arm vein of the patient. Through this IV line, sedatives or any other medication will be injected.
A dye (contrast agent) is injected through the catheter to view any blockage.
Series of X-rays are taken as the dye moves through the blood vessels.
while the test is going on , Electrodes will be placed on the patient’s chest to monitor heartbeat. A blood pressure too shall be monitored.
This is not a painful procedure. it will approximately take from 30 minutes to 2 hours depending on the case to case basis.
In some conditions, other procedures, such as angioplasty can also be carried out at the same time, which includes inserting a balloon or a small tube termed a stent through the catheter to open a narrowed artery.
Post procedure, the catheter is removed. One is asked to rest and lie still for few hours to prevent bleeding from the cut.
Mostly, patients recover enough to leave the hospital on the same day of the procedure. but in some cases patient stays over night in the hospital.
The patient can eat or drink soon after the procedure.
Analysis of the test can be obtained the same day.
One can resume to normal activities the next day.
Angiography is a safe procedure and there could be minor complications:
Bruising or bleeding in the area where the incision was performed
Infection in the area of incision
Mild or moderate allergic reactions due to the contrast agent
