Coronary angiography enables the detection and subsequent treatment of clogged vessels in the diagnosis of heart problems seen in patients. Small tubes (catheters) are inserted into the circulatory system under x-ray guidance to obtain information about blood flow and pressure within the heart and to determine whether there are blockages in the blood vessels feeding the heart muscle. In traditional angiography performed through the femoral artery in the groin area, a catheter is inserted into the femoral artery from the groin area, and then the catheters are placed into the cardiac vessel and contrast material is injected. Thus, thanks to the X-ray, the heart vessels are clearly seen on the screen. In radial angiography, the catheter is placed through the radial artery in the wrist and the same images are obtained.
It is a preferred diagnostic method due to the ease and comfort radial angiography provides to the patient. In the traditional femoral method, after the cannula is removed from the groin, patients must not move their leg for 2 to 6 hours and keep a sandbag on it to prevent bleeding. In some cases, internal bleeding may occur despite the sandbag and long periods of immobility, and this bleeding may even require blood transfusion or repair with open surgery in the operating room. These complications can be prevented with radial angiography. The radial artery is smaller and closer to the surface of the skin. Therefore, the risk of internal bleeding is eliminated and in case of any external bleeding, it can be easily stopped. After coronary vessel images are obtained, the catheter is removed and bleeding is easily stopped with a bandage that prevents bleeding from the catheter entry site. There is no need to be immobile during radial angiograms and patients can immediately return to their daily activities. In general, patients find radial catheterization more convenient and comfortable than femoral catheterization. Because they can sit, walk and eat right away. This is a particular advantage especially for patients with back problems. Because there is no need for the heavy pressure of the sandbag on the leg and long-term immobility. This also provides an economic advantage for the patient by shortening the hospital stay. ''
