Color Doppler of Portal and Splenic Venous Systems

Color Doppler of the portal and splenic venous systems is an advanced ultrasound method that provides detailed assessment of blood flow through the portal vein, its branches, as well as the splenic and gastroomental veins. The examination utilizes high-frequency ultrasound waves and color display techniques to clearly demonstrate the direction and velocity of blood flow, as well as any potential narrowing, thrombosis, or reflux. The procedure is completely non-invasive, painless, and safe, with no radiation exposure.

When Is Color Doppler of Portal and Splenic Venous Systems Recommended?

The examination is indicated for patients with suspected portal hypertension, portal vein thrombosis, liver damage, cirrhosis, ascites, or splenomegaly (enlarged spleen). It is also used for monitoring patients following liver transplantation or those with chronic liver and spleen conditions, enabling timely detection of blood flow changes and prevention of complications.

What Can Color Doppler Detect?

Color Doppler precisely visualizes the status of portal and splenic blood flow, identifying venous narrowing, presence of thrombi, reflux or reversed blood flow, as well as flow anomalies resulting from cirrhosis, inflammation, or postoperative changes. The examination provides information on flow velocity and vascular resistance, aiding in the diagnosis of portal hypertension and assessment of liver and spleen function.

How Is the Examination Performed?

The procedure takes approximately 15–20 minutes. The patient lies in a comfortable position while the radiologist applies gel to the abdominal area. The probe systematically examines the portal vein, its branches, splenic veins, and splenic venous drainage. Color Doppler imaging enables real-time visualization of blood flow direction and velocity, with immediate results and recommendations for further therapy or follow-up examinations.

Advantages of Color Doppler of Portal and Splenic Venous Systems

The primary advantages of this method include high accuracy in detecting vascular changes, painlessness, safety, and immediate insight into blood flow status. The examination is repeatable and suitable for monitoring disease progression in liver and spleen conditions, evaluating treatment effectiveness, and preventing complications such as thrombosis or portal hypertension.
