Computed Tomography
A highly accurate diagnostic imaging method that allows obtaining detailed cross-sectional images of internal organs and blood vessels for precise assessment of their structure and pathological changes.
Procedure Description
Computed tomography (CT) is an integral part of modern diagnostic medicine. It is a diagnostic examination that provides detailed cross-sectional visualization of all anatomical structures and organs. When considering the use of CT in cardiac surgery, its high diagnostic value should be emphasized first and foremost.
This method allows surgeons to assess the size of the heart chambers and blood vessels, as well as the presence of atherosclerotic processes, which are often accompanied by vascular wall calcification and pose a significant risk during surgical interventions.
In addition to standard CT imaging, CT angiography is also used in diagnostic practice. This method involves the administration of a radiopaque contrast agent into the bloodstream during the examination (the contrast is usually injected intravenously). It is used in the following clinical cases: detection of narrowing (stenosis) or blockage (occlusion) of the coronary arteries in coronary artery disease. CT angiography clearly visualizes atherosclerotic plaques that narrow the arterial lumen, as well as calcium deposits; aneurysm or dissection of the aorta; detection of lesions in the renal arteries, carotid arteries, arteries of the lower extremities, aneurysms of cerebral and visceral arteries; diagnosis of pulmonary embolism; congenital anomalies or malformations of blood vessels, as well as vascular tumors.
Indications for CT examinations, and especially CT angiography, are determined by a cardiologist or cardiovascular surgeon, as the area of investigation is selected based on the diagnosis and other clinical data.
