X-ray Endovascular Dilation
Dilation is repeated several times, after which the catheter is removed. When the atherosclerotic process occurs under the influence of compression the vessel wall becomes depressed and develops athermanous plaques. Contraindications are diffuse stenosis, sharp bends and twisting of the arteries, eccentric location of the site of stenosis.
After removal of the catheter angiographic catheter guide therapeutic control X-ray vision carefully injected into the area of stenosis. Syringe equipped with a pressure gauge into the lumen formed by the inner tube and shell, pour diluted radiopaque substance, resulting in a balloon, stretching out evenly, putting pressure on the walls of the narrowed vessel.

X-ray vascular dilatation in atherosclerotic narrowing performance of coronary arteries of the heart, stenosis of the brachiocephalic branches of the aortic arch, renal artery stenosis or atherosclerotic fibro-muscular nature, narrowing the celiac trunk and superior mesenteric artery, with a total occlusion and external iliac arteries and lower limb vessels.
X-ray vascular dilation is one of the most effective ways to treat the limited (usually no more than 10 cm), segmental stenosis of blood vessels. This method is used in approximately 15% of patients requiring surgical treatment of occlusive lesions of blood vessels.
