In "retrograde" flow, the flow would reverse (e.g. veins flow away from heart or arteries flow towards the heart). However, "retrograde" flow can be both abnormal or normal. For example, in portal hypertension , there is an abnormal portal venous flow where it flows away from the liver (hepatofugal flow) instead of the normal flow towards liver ...
Doppler ultrasound of the liver is typically utilized to confirm or suggest the diagnosis. Common findings on liver doppler ultrasound include increased phasicity of portal veins with eventual development of portal flow reversal. The liver is usually enlarged but maintained normal echogenicity. A liver biopsy is required for a definitive diagnosis.
Color Doppler Ultrasound is the most useful imaging tool used to identify aneurysms, thrombosis, and branching patterns of the portal venous system, and to determine if treatment or surgery will be necessary. [5]
Approximately 75% of hepatic blood flow is derived from the portal vein, while the remainder is from the hepatic arteries. [4] Unlike most veins, the portal vein does not drain into the heart. Rather, it is part of a portal venous system that delivers venous blood into another capillary system, the hepatic sinusoids of the liver.
Caudate lobe hypertrophy on ultrasound due to cirrhosis Hepatofugal (non-forward) flow in portal vein. The diagnosis of cirrhosis in an individual is based on multiple factors. [32] Cirrhosis may be suspected from laboratory findings, physical exam, and the person's medical history. Imaging is generally obtained to evaluate the liver. [32]

Combined with Doppler imaging, nearby blood vessels can also be evaluated. Endoscopic ultrasonography is most commonly used in the upper digestive tract and in the respiratory system. The procedure is performed by gastroenterologists or pulmonologists who have had extensive training.
