[Ultrasound scanning and invasive methods of examination of the celiac trunk and superior mesenteric artery in the diagnosis and evaluation of results of the surgical treatment of their stenotic lesions].

The ultrasound duplex scanning with colored pictures of blood flow in the celiac trunk and superior mesenteric artery with occlusive lesion of them by atherosclerosis or compression by the diaphragm is a highly sensitive and sufficiently accurate research method. It allows to detect disturbances in patency of these vessels, the state of blood flow in them and to assess the results of operative treatment. A comparison of the data of preoperative ultrasound duplex scanning and aortic-arteriography has shown coincidence of the localization and, in most cases, the degree of stenosis of the celiac trunk and superior mesenteric artery. The results of direct electromanometry proved to be similar to those of dopplerography in 88% of cases before the operation and in all the cases after decompression of the celiac trunk.
