The price of carotid arteriography is still relatively expensive, the price is almost around 5,000 yuan, due to regional variability or different hospital levels, the price slightly fluctuates up and down. Carotid arteriogram is able to see the specific situation of the patient’s carotid artery very clearly, including the specific location of the carotid artery stenosis, the specific length of the stenosis, the degree of stenosis, as well as blood flow and other conditions. It is done mainly under X-ray, and usually requires the injection of a contrast agent called iodine contrast into the artery in order to fill the artery and measure the carotid artery more clearly. Although carotid arteriograms are very expensive, patients with health insurance are reimbursed for about half of the cost, leaving them to pay between$2,000 and$3,000 on their own.
