The study was conducted between 29 January to 25 April 2000. Participants were 30 healthy people, 15 males and 15 females, with age ranged from 15 to 45 years. It was found that the diameter of portal vein and spleen vein increases during deep-to-stop breathing test, in comparison with that during normal breathing. After eating, the diameter, blood rate and flow of portal vein are increase, blood stagnant index of portal vein decreases, rate of portal vein to spleen vein blood flow decreases. The portal vein blood flow is higher in men than in women. There is not any difference in diameter and rate of portal vein and spleen vein, portal vein blood flow, rate of portal vein to spleen vein blood flow and blood stagnant index of portal vein between two genders

A portal vein aneurysm is divided into two groups; an extrahepatic portal vein aneurysm and an intrahepatic portal vein aneurysm. The morphology of an aneurysm can be divided into types such as fusiform, bilobulated and saccular. A saccular aneurysm that arises from the intrahepatic portal branch is extremely rare. We report here a case of a saccular aneurysm of the intrahepatic portal branch mimicking an intrahepatic hypervascular mass, as seen on a dynamic CT scan, with the radiological findings.

Liver have complex functions with a high workload. Various liver diseases are the result of the interaction of diverse genetic and environmental factors. Moreover, other systemic diseases may also affect liver, producing corresponding manifestations, such as abnormal liver function tests, portal vein or hepatic vein thrombosis, portal hypertension, hepatosplenomegaly and liver space-occupying lesions. Therefore, it is extremely important for hepatologists to have an in-depth understanding of other systemic diseases of hepatic manifestations, especially hematologic, connective tissue, endocrine, and circulatory, in order to improve the level of clinical diagnosis and treatment.

PURPOSE: To describe the CT findings of portal vein aneurysm in eight patients. MATERIALS AND METHODS: Allpatients included in this study (two men and six women) under went CT examinations between October 1996 and June1998. Of these eight, three were suffering from hepatic disease and portal hypertension. We determined thelocation, shape, size, and characteristics of the lesions, and the presence or ab-sence of portal vein anomaly. RESULTS: S even patients had intrahepatic portal vein aneurysm (at the umbilical por-tion of the left portal veinin five patients, between the transverse and umbilical por-tion of the left portal vein in one, and at thebifurcation of the anterior and posterior branch of the right portal vein in one), while extrahepatic portal veinaneurysm, at the confluence of the superior mesenteric and splenic vein was found in only one. Lesions werecyst-shaped in seven cases and saccular in one, and showed well - circum scribed, markedly enhanced mass, whichcommunicated with the portal vein and/or gives off major branches. Portal vein anomaly, in which the rightanterior segmental portal vein originated from the umbilical portion of the left portal vein, was seen in threepatients. In all three, intrahepatic portal vein aneurysm was present at the umbilical portion of the left portalvein, and in one, the umbilical portion of the left portal vein was located to the right of the Cantlie line. CONCLUSION: CT examination can help reveal portal vein aneurysm by detectinga well - circumscribed, markedlyenhanced mass which communicates with the portal vein and/or gives off major branches.

Left-sided gallbladder, a rare congenital anomaly, is defined as a gallbladder located to the left of the round ligament. Rarer is the definitely diseased left-sided gallbladder in the literature. The authors experienced two true type cases of the left-sided gallbladder. One case was associated with portal vein anomaly.

We compared 87 portographic filling defects detected by portal CT in 64 patients were compared with those obtained by indirect portography. The indirect portography could visualize portogram only in anterior-posterior view. But the portal portal CT could visualize both portogram and hepatogram. We examined the portal CT and indirect portography and compared the accuracy of the both methods to evaluate the limitation and significance of the indirect protography. The mass shape lesions were seen on the portal CT which means portal flow defects of the mass lesions only could not depict totally in indirect portography (0%, 0/41). And the larger defects than real mass lesion were seen in portal CT means mass with associated portal flow defect and find portal vein invasion around the mass in 52% (24/46) of the indirect portography. Among them, only 66% of mass were detected correctly in the indirect portography comparing with mass lesion in portal CT. In summary, indirect portogram could not detect small filling defects which detected in portal CT and could not depict the extent of large filling defects. It also could not visualize correctly the protal flow in non-lesion side of the liver parenchyma.

Twenty cases of hepatocelluar carcinoma were examined by selective celiac and superior mesentericarteriography. Obstruction of the main portal vein due to tumor thrombus was revealed in 7 cases and 3 of thesecases had carvenous transformation of the protal vein(CTPV). The authors intended in this study to evaluate CTPVgroup and non-CTPV group clinically and radiologically. The results obtained are as follows; 1. The duration ofillness was shorter in CTPV group than non-CTPV group. 2. There was no significant difference in tumor sizebetween two groups, and main portion of tumor was located in the right lobe in both groups. 3. Arterioportal shuntwas present in 2 of 4 cases in non-CTPV group, but was no present at all in CTPV group. 4. Hepatofugal collateralsof portal vein were developed in all but one in both groups. 5. There was no significant difference in bloodchemistry between two groups. 6. CTPV may play an important role maintain the hepatic blood flow.
