RESUMO
The paper gives a detailed characterization and describes the importance of instrumental methods for examination of patients in the diagnosis of thoracic and thoracoabdominal aortic aneurysms. Provides a differentiated protocol of the examination of patients as dependent on the clinical course, disease stage and nemodynamic stability of the patient's status. Delineates the tactics of the examination of patients with acute and chronic dissection of the proximal and distal segments of the aorta as dependent on hemodynamic stability. Emphasis is laid on the key role of computed tomography and magnetic resonance tomography in the diagnosis of aortic aneurysms.

Eighty-seven autovenous shunts were examined using ultrasonic dopplerography to assess the patency of aorto-coronary shunts in 32 patients. B-scan was used to visualize the shunts and measure their inner diameter. Liner blood flow rate was measured with a Doppler adapter distinguishing the direction of the flow. Methodologic aspects of the application of this method to the assessment of the patency and function of aorto-coronary shunts are outlined. To verify the method, selective angiography was performed in 18 patients. A significant correlation was demonstrated between the two techniques. Ultrasonic Doppler scanning measuring linear blood flow rate is a safe, non-invasive and reliable method for the assessment of patency of aorto-coronary shunts. It can be used on an out-patient basis.
