Clinical Pearl

Occasionally an abdominal ultrasound reads: no flow seen in portal vein (PV), and you are left with the impression of a new portal vein thrombosis.  Before starting anticoagulation, you should confirm the presence of thrombosis with CT or MRI.  Sometimes, with cirrhosis and portal hypertension (ie. high resistance to flow), flow within the PV is sluggish (and can even be reversed) and it may appear to Doppler as “no flow” when in fact it could be static blood without actual thrombosis.  CT and MRI will parse these possibilities apart.
