Portal vein thrombosis | Radiology Reference Article …
In chronic cases, cavernous transformation of the portal vein may be seen, with numerous periportal veins replacing the normal single channel of the portal vein. Ultrasound. Acute thrombosis may be difficult to detect with grey-scale imaging alone, as the thrombus may be hypoechoic. With time, it becomes more echogenic and easier to identify 3. Color Doppler should be able to demonstrate absent flow in the portal vein and even to detect partial thrombosis, but attention to the Doppler gain …

Ultrasound of Portal Vein Thrombosis | SIFSOF
As cited in Portal vein thrombosis: Ultrasound imaging “the improvement of imaging procedures the number of patients with diagnosed portal vein thrombosis is increasingly growing. With a negative predictive value of 98% color Doppler ultrasound is considered as imaging modality of choice in detecting portal vein thrombosis.”

Portal Vein Thrombosis: Imaging the Spectrum of Disease …
Acute and Chronic Portal Vein Thrombosis PVT is an obstruction in the trunk of the PV. It is considered acute when symptoms such as transient abdominal pain, fever, nausea, and diarrhea develop less than 60 days before medical assessment [ 1 ]. However, acute PVT may also be asymptomatic when there is partial PVT obstruction.

Portal vein thrombosis – WikEM
Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, leading to increased pressure in the portal vein system and reduced blood supply to the liver.

Ultrasound is also an excellent means of evaluating patients for portal vein (PV) thrombosis and Budd-Chiari syndrome (BCS), which may precipitate acute deterioration of liver function in patients with cirrhosis and HCC. In addition, duplex Doppler ultrasound has an important clinical role in monitoring patients following placement of transjugular intrahepatic portosystemic shunts (TIPS), which may serve as an adjunct to medical therapy for the treatment of GE varices or refractory ascites.
Portal vein thrombosis in cirrhosis – PubMed
Portal vein thrombosis (PVT) is being increasingly recognized in patients with advanced cirrhosis and in those undergoing liver transplantation. Reduced flow in the portal vein is probably responsible for clotting in the spleno-porto-mesenteric venous system. There is also increasing evidence that hypercoagulability occurs in advanced liver disease and contributes to the risk of PVT. Ultrasound based studies have reported a prevalence of PVT in 10-25% of cirrhotic patients without …
