MainUltrasound Diagnostics Department

Ultrasound Diagnostics Department

The main task of the Department is performing of ultrasound diagnosis. Priority works are echocardiography (EchoCG, ultrasound of the heart) and duplex scanning of vessels (duplex sonography, DS). In addition, the Department performs a wide range of other ultrasound, such as: ultrasound of the abdominal cavity, kidneys, prostate and bladder, uterus and appendages, thyroid gland, pleural cavities, etc.

The Department also carries out specialized ultrasound of the heart, such as: echocontrast study, pharmacological stress EchoCG, transesophageal EchoCG.

Echocontrast study:

As a contrast, a 0.2% hydrogen peroxide solution is used which, upon contact with blood (when injected into the ulnar vein), decomposes into oxygen bubbles and water. The formed oxygen bubbles are clearly visible with the help of ultrasound, and the doctor can trace their distribution in the heart cavities. The capillary barrier of the lungs does not overcome this contrast and does not enter the systemic circulation.

Indications for echocontrast study are:

  1. Suspected defects of the septum (atrial septal defect - ASD, ventricular septal defect - VSD, functioning oval window) in the case that the results of conventional echocardiography leave doubts in presence or absence of a defect.
  2. Clarification of the anatomy of the superior vena cava (SVC) to confirm the fact of additional (persistent) left SVC, the entrance of SVC into the left atrium or coronary sinus.
  3. Clarification of the anatomy of congenital heart disease (CHD) in the case of combined CHD.

The procedure does not require special preparation. At the moment it is held on Fridays from 11.00 on the pre-appointment, phones 491783, 491814.

The duration of the procedure does not exceed 30 minutes.

The patient is referred to the study by the doctors of the dispensary or inpatient departments of the "Gomel Regional Clinical Cardiology Center".

Pharmacological stress EchoCG:

The basis is identification of indirect signs of ischemic heart disease (IHD), such as violations of movement of individual parts of the myocardium of the left ventricle (zones of hypokinesia, akinesia, dyskinesia). The occurrence of ischemia, characteristic for IHD, can be caused by administration of the dobutamine in increasing doses. The dobutamine, when administered intravenously with a dispenser, causes occurrence of rapid heartbeat (tachycardia), which provokes occurrence of ischemia.

The diagnostic accuracy of stress EchoCG is higher than that of the usual ECG loading test (bicycle ergometry, treadmill test).

Indications for study are:

  1. For chronic ischemic heart disease (clarification of diagnosis of angina pectoris in cardialgia of unclear etiology; assessment of the state of coronary arteries in the cases when traditional loading tests can not be performed; determination of angiographically significant (> 50%) stricture formation of coronary arteries; assessment of the severity of ischemia and presumed basin of lesion of coronary channel).
  2. Myocardial syndrome, "stunned" by acute ischemia, without development of necrotic changes.
  3. Before and after revascularization operations (preoperative risk assessment in cases of shunting operations; assessment of effectiveness of revascularization; determination of restenosis of coronary arteries after angioplasty procedure, stenting and shunting operations).
  4. Stratification of risk groups after myocardial infarction.
  5. Assessment of effectiveness of thrombolytic therapy.
  6. Diffuse cardiosclerotic (nonspecific) lesions of the cardiac muscle.
  7. When deciding the necessity and expediency of heart transplantation.

In terms of preparation, it is necessary to fill out an informed consent form for performing the procedure (the form is to be filled out by the attending physician), to have on hand the outpatient card or the case history in which the attending physician has formulated the study purpose, and to have results of EchoCG, ECG.

The duration of the procedure does not exceed 1 h 40 min.

The patient is sent to the clinical study by the doctors of the dispensary or inpatient departments of the "Gomel Regional Clinical Cardiology Center".

Transesophageal echocardiography (TEE):

TEE is used for a more detailed examination of the heart with the help of a sensor resembling an endoscope when placed in the esophagus, which is closely attached to the heart.

Indications for examination:

  1. Uninformative traditional ECG.
  2. Assessment of condition of the prosthetic and natural valves.
  3. Search for vegetation in infective endocarditis.
  4. Search for sources and ways of embolization of blood vessels of the greater and lesser circulations (thrombosis, including one of the left atrial appendage, space-occupying lesions, vegetations, functioning oval window, phenomenon of spontaneous contrasting).
  5. Interatrial septum fenestrations (defects, functioning oval window).
  6. Pathology of thoracic aorta (aneurysms, wall dissection, intramural hematomas).
  7. Complications of acute myocardial infarction (cardiac break, including acquired VSD and papillary muscle tear, left ventricle cavity thrombosis, left ventricle aneurysm including a false one).
  8. Congenital heart defects (CHD) to clarify their anatomy.
  9. Tumors of the heart.

In terms of preparation, it is necessary to fill out an informed consent form for performing the procedure (the form is to be filled out by the attending physician), to have on hand the outpatient card or the case history in which the attending physician has formulated the study purpose, and to have results of EchoCG, ECG, fiberoptic gastroduodenoscopy or results of fluoroscopy of the esophagus with barium.

The test is performed on an empty stomach or after 6 hours after the last meal. Removable dentures must be removed before the procedure.

The duration of the procedure does not exceed 60 min.

The patient is sent to the clinical study by the doctors of the dispensary or inpatient departments of the "Gomel Regional Clinical Cardiology Center".

You can make an appointment for the study at our website or by phone 49-17-63 on weekdays from 11.00 to 16.00 (lunch from 12.00 to 12.30).
