Clinical significance of inferior right hepatic vein
In our case, we discussed a malpositioned functioning permanent catheter in the hepatic vein
. A catheter malposition may end up in the hepatic vein
as was the case in our study.
The inferior right hepatic vein
: ultrasonic demonstration.
As part of hepatitis work-up, the patient underwent liver ultrasound, which revealed dilated IVC and hepatic veins
Five diagnostic criteria must be met to diagnose INCPH: (1) clinical evidence of portal hypertension, (2) absence of cirrhosis or advanced fibrosis on liver biopsy, (3) intrahepatic etiologies of liver disease such as viral hepatitis and fatty liver disease, (4) Sarcoidosis, Schistosomiasis, and congenital hepatic fibrosis, and (5) patent portal and hepatic veins
Only a proper bending angle can ensure the needle to move toward portal vein after puncturing outside hepatic vein
and then puncture into the branch of portal vein.
In these studies, portal vein and hepatic vein
diameters are combined, their waveform changes, and the transient time is estimated using contrast-enhanced ultrasonography.
Right hepatic vein
was selectively cannulated and catheter position confirmed by vein angiogram.
As we can see from Table 1 the most commonly reported location of thrombosis is in the hepatic veins
(6/19) followed by DVT (5/19).
An abdominal ultrasound with Doppler revealed patent TIPS and patent hepatic vasculature including the hepatic vein

. There are few clustered microcalcifications in the cyst.
wedge pressure was only available for 15 of the 46 patients (33%) and was therefore not included in the comparative analysis.
