Clinical significance of inferior right
hepatic vein. Am.
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 (Figure 1).
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 [4].
In these studies, portal vein and
hepatic vein diameters are combined, their waveform changes, and the transient time is estimated using contrast-enhanced ultrasonography.
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.
Caption: FIGURE 1: Triple phase CT scan notable for a near water attenuating cyst occupying the central sections of the liver with involvement of the middle
hepatic vein. There are few clustered microcalcifications in the cyst.
Hepatic vein wedge pressure was only available for 15 of the 46 patients (33%) and was therefore not included in the comparative analysis.
