Overview
Contrast enhanced ultrasonography (CEUS) may be helpful in the diagnosis of portal vein thrombosis. Findings on CEUS suggestive of portal vein thrombosis include pulsatile flow in a portal vein thrombus, absence of enhancement of the portal vein thrombus in the arterial phase, and differentiate between benign and malignant portal vein thrombosis.
Other Imaging Findings
Endoscopic Ultrasound (US)
- Endoscopic US may be helpful in the diagnosis of portal vein thrombosis. Findings on an endoscopic US suggestive of portal vein thrombosis include:[1][2][3]
- Detecting small and non-occluding thrombi
- Discovering portal invasion by tumors
MR angiography
- MR angiography may be helpful in the diagnosis of portal vein thrombosis. Findings on MR angiography suggestive of portal vein thrombosis include:[4]
- Flow direction in the portal venous system and its patency
- Identify a cavernomatous transformation
- Presence of varices
- Correct function of surgical shunts
Contrast-enhanced ultrasound (CEUS)
- Contrast-enhanced ultrasound may be helpful in the diagnosis of portal vein thrombosis. Findings on CEUS suggestive of portal vein thrombosis include:[5][6]
- Pulsatile flow in a portal vein thrombus
- Absence of enhancement of the portal vein thrombus in the arterial phase
- Differentiate between benign and malignant portal vein thrombosis
