What does a color Doppler ultrasound of the portal venous system examine?

Color Doppler ultrasound of the portal venous system is used to detect conditions such as cavernous transformation of the portal vein and portal hypertension. Patients are advised to promptly visit a reputable hospital for examination.

The portal venous system refers collectively to the functional blood vessels of the liver, formed by the confluence of the superior mesenteric vein and the splenic vein. Color Doppler ultrasound of the portal system is a type of color imaging technique primarily used to evaluate the portal vein and the veins of various internal organs that contribute to it. Generally, this ultrasound examination has a relatively high diagnostic accuracy and can effectively detect diseases such as cavernous transformation of the portal vein, portal hypertension, portal vein thrombosis, portal vein tumor thrombus, and hepatic arterio-portal fistula. If a patient requires a portal venous system ultrasound, it is recommended to undergo the test at a正规 medical institution to improve diagnostic accuracy and reduce the risk of missed or incorrect diagnoses.

Patients are also advised to maintain healthy daily habits, keep a calm and balanced mindset, and avoid excessive tension or anxiety. They should go to bed early and rise early, ensure sufficient sleep, engage in appropriate physical activity, but avoid strenuous exercise.
