Endoscopic ultrasound of the colon is performed when a malignant tumor of the intestine is suspected, it is prescribed after chemotherapy and radiation therapy to assess the effectiveness of the treatment of the oncological process. An echoendoscope with a light source and an ultrasound sensor is inserted into the intestine through the anus. The technique allows…
Endoscopic ultrasound of the pancreas is an ultrasound examination of the parenchyma and ducts of the pancreas, the zone of regional blood and lymph flow, performed endoscopically. It is performed through the wall of the stomach and the duodenum using a special device – an echoendoscope equipped with lateral optics and a high-frequency ultrasound sensor. Endoscopic…
Esophagus endoscopic ultrasound is the study of the structure of the esophageal tube using endoscopic (intraluminal) ultrasound. Allows for clarifying diagnostics for varicose veins, diverticula, tumors, strictures, extraorgan compression of the esophagus. Endoscopic ultrasound is indispensable in determining the depth of tumor invasion, conducting differential diagnosis between benign and malignant neoplasms, and assessing regional metastasis. Various…
Bile ducts endoscopic ultrasound is a method of visualization of the bile ducts using endoscopic ultrasound. It can be performed antegrade (through cholangiostomy) or retrograde (through the large duodenal papilla during retrograde cholangiopancreatography). Endobiliary ultrasonography is an effective method of diagnosing the pathology of the ductal system: developmental abnormalities, choledocholithiasis, papillitis, tumors of the gallbladder,…
Stomach endoscopic ultrasound is a study of the walls of an organ using a combined technology that combines endoscopic access and ultrasound scanning. It has diagnostic significance in the detection of submucosal tumors, polyps, erosive and ulcerative defects, deformations of the gastric wall from the outside. Endoscopic ultrasound allows you to clearly examine each of…
Many people know that blood type is an innate characteristic and it does not change throughout a person’s life. Nevertheless, on Internet forums you can often see the stories of people who at some point found out that their blood type is not the same as it was before. Is this possible, and if so,…
Abdominal aorta ultrasound are ultrasound methods that allow for qualitative and quantitative analysis of blood flow and determine the causes of its disorders in the abdominal aorta and the parietal and visceral branches extending from it. It includes Doppler and duplex scanning modes. Ultrasound of the aorta is informative for detecting aneurysmal, occlusive, stenosing and…
Inferior vena cava ultrasound is a method of non-invasive examination of the inferior vena cava and its main branches using ultrasound waves and special sensors. Allows you to assess the diameter of the venous trunk, the lumen of the veins and the condition of the valves, gives an idea of the existing venous thrombi, which…
Leg vein ultrasound – echographic methods for assessing the anatomy of blood vessels and regional blood flow along venous highways. In vascular surgery, three types of angioscanning are used, which complement each other: Dopplerography, duplex and triplex modes. The methods are used in the diagnosis of vascular pathology (vasculitis, varicose veins, thrombophlebitis). During the ultrasound…
Arterial ultrasound of the lower extremities is a method of recording and evaluating arterial blood flow in the vessels of the legs in real time. It can be performed using Dopplerography, duplex or triplex scanning. Allows quantitative measurement of blood circulation parameters, to identify pathological processes in the arteries of the extremities (occlusion, atherosclerotic narrowing,…
