Wrist Angiography and Stent Application

Coronary aniography is a method frequently used by cardiologists to detect occlusion and stenosis in the heart vessels. If necessary during the procedure and the patient’s kidney functions are suitable, angioplasty, that is, vascular opening, is also performed. Thin tube to the inguinal artery (femoral artery) or wrist artery (radial artery). inserting is the start of the procedure.

Although inguinal vein angiography is the traditional method used for many years, complications such as bleeding during and after the procedure, damage to the leg nerve, pseudoaneurysm, arterial fistula may occur. After the procedure, patients should lie down for at least four hours and ten hours after the angioplasty procedure. poses a problem for elderly patients and patients with back problems.

The inguinal artery is not the only way to reach the heart. The wrist artery is also used very frequently in recent years to reach the heart. The radial artery is thinner than the femoral artery. Complications such as bleeding and nerve damage are much less. Most importantly, the sheath (thin) used during the procedure plastic tube) is withdrawn immediately after the procedure and the patient can stand up immediately. Patients do not need to lie in bed for a long time.

Is every patient suitable for wrist angiography?

Because the radial artery is thin, it can sometimes be occluded after the procedure. Therefore, it is necessary to make sure that the ulnar artery, which is the other vessel that supplies clean blood to the hand, is open. Your doctor will perform the Allen test. The radial artery is on the thumb side of the wrist, and the ulnar artery is on the little finger side. In the Allen test, your doctor will ask you to open and close your hand while pressing on the radial and ulnar arteries. During this time, your hand will turn pale. Your hand should turn pink in less than 8 seconds when the pressure on the ulnar artery is removed. If it does not turn pink, it means there is a problem in the ulnar artery and radial angiography is not suitable.

Angiography preparations made from the wrist are similar to angiography performed in the groin. Electrocardiogram, lung film, blood tests, especially kidney function and bleeding tests are required. You must be fasting for at least 6 hours before the procedure. A sedative drug is given before the procedure. Local anesthesia on the radial artery in the wrist After the puncture is made and the tube is placed, the procedure is continued. Sometimes a very serious spasm (shrinkage) develops in the radial artery; in this case, the procedure is continued from the inguinal vein.

Wrist angiography is an alternative to inguinal angiography, especially for patients who have low back problems due to the problem of lying on their back for a long time, and those who are worried about bleeding.
