[Role of noninvasive vascular function tests before arterial vascular surgery]

Area of Science:

• Vascular Medicine
• Diagnostic Imaging
• Cardiovascular Physiology

Background:

• Noninvasive functional tests are crucial for evaluating arterial circulation.
• These tests primarily utilize Doppler ultrasound to measure systolic blood pressures and blood flow pulsatility in the extremities.
• Objective data from these tests are essential for surgical indications and treatment outcome analysis.

Purpose of the Study:

• To highlight the indispensable role of noninvasive functional vascular testing in specific clinical scenarios.
• To define the utility and limitations of these tests in various arterial diseases.
• To identify areas requiring further research in hemodynamic examinations.

Main Methods:

• Doppler ultrasound analysis of arterial blood flow.
• Measurement of systolic blood pressures in the extremities.
• Assessment of blood flow pulsatility.

Main Results:

• Noninvasive testing is indispensable for chronic arterial obstructive disease of the lower extremities and carotid artery pathology.
• Hemodynamic tests are of limited value in aneurysmatic disease, vascular trauma, and arterial entrapment syndromes.
• Hemodynamic examinations for renal and visceral arterial abnormalities require further development and validation.

Conclusions:

• Noninvasive functional tests are essential for diagnosing and managing specific arterial conditions, particularly obstructive diseases.
• The clinical utility of hemodynamic tests varies significantly across different vascular pathologies.
• Further research is needed to establish the role of hemodynamic examinations in renal and visceral arterial abnormalities.
