[Duplex sonography in gastroenterology]

Area of Science:

• Vascular imaging
• Medical diagnostics
• Ultrasound technology

Background:

• Noninvasive assessment of blood flow is crucial for diagnosing various vascular and organ conditions.
• Conventional and colour-coded duplex sonography offer practical methods for evaluating blood flow.
• Existing methods are effective in identifying specific pathologies like portal hypertension and arterial stenosis.

Purpose of the Study:

• To evaluate the utility of duplex sonography in examining blood flow within vessels and organs.
• To highlight the practicability of duplex sonography in diagnosing specific clinical conditions.
• To explore the potential future applications of duplex sonography in medical diagnostics.

Main Methods:

• Utilizing conventional duplex sonography for blood flow assessment.
• Employing colour-coded duplex sonography for enhanced visualization.
• Applying these noninvasive techniques to examine portal hypertension, portal thrombosis, Budd-Chiari syndrome, and mesenteric artery stenosis/occlusion.

Main Results:

• Duplex sonography effectively examines blood flow in vessels and organs noninvasively.
• The method is highly practicable for diagnosing portal hypertension, portal thrombosis, and Budd-Chiari syndrome.
• Stenosis and occlusion of the coeliac trunk and superior mesenteric artery can be reliably detected.

Conclusions:

• Duplex sonography is a valuable noninvasive tool for vascular and organ blood flow assessment.
• Its practicability is demonstrated in managing conditions such as portal hypertension and mesenteric artery diseases.
• Future applications may include the differential diagnosis of space-occupying lesions, though quantitative measurements are primarily for research.
