AIM:To evaluate the role of three-dimensional contrastenhanced magnetic resonance angiography (3D CE MRA) in the diagnosis of Budd-Chiari syndrome (BCS).METHODS: Twenty-three patients with BCS underwent 3D CE MRA examination, in which 13 cases were secondary to either hepatocellular carcinoma (11 cases), right adrenal carcinoma (1 case) or thrombophlebitis (1 case) and 10suffered from primary BCS. The patency of the inferior vena cava (IVC), hepatic and portal veins as well as the presence of intra- and extrahepatic collaterals, liver parenchymal abnormalities and porto-systemic varices were evaluated. Inferior vena cavography was performed in 10 cases. The diagnosis of IVC obstruction by 3D CE MRA was compared with that demonstrated by inferior vena ***: The major features of BCS could be clearly displayed on 3D CE MRA. Positive hepatic venous signs included tumor thrombosis (9 cases), tumor compression (2 cases), nonvisualization (4 cases) and focal stenosis (2 cases). Positive IVC findings were noted as severe stenosis or occlusion (10 cases), tumor invasion (2 cases), thrombosis (3 cases), thrombophlebitis (1 case) and septum formation (3 cases). Intrahepatic collaterals were shown in 9 patients,2 of them with 'spider web' sign. The displayed extrahepatic collaterals included dilated azygos and hemi-azygos veins (13 cases) and left renal-inferior phrenic-pericardiophrenic veins (2 cases). The occlusion of the left intrahepatic portal veins was found in 2 cases. Porto-systemic varices were detected in 10 patients. Liver parenchymal abnormalities displayed by 3D CE MRA were enlargement of the caudate lobe (7 cases), heterogenous enhancement (18 cases) and complicated tumors (13 cases). Compared with the inferior vena cavography performed in 10 cases, the accuracy of 3D CE MRA was 100% in the diagnosis of IVC ***: 3D CE MRA can display the major features of BCS and provide an accurate diagnosis.

Two pairs of Pt(Ⅱ) enantiomers((RR)/(SS)-Py Pt,((RR)/(SS)-Py: N,N’-(1,2-diphenylethane-1,2-diyl)dipicolinamide;(RR)-P/M-QPt,((RR)/(SS)-Q: N,N’-((1R,2R)-1,2-diphenylethane-1,2-diyl)bis(quinoline-2-carboxamide)) were synthesized, respectively, with good circularly polarized luminescence(CPL) and tunable dissymmetry factors(g) by molecular self-induction with(RR)/(SS)-1,2-diphenylethane-1,2-diamine as carbon chiral sources. In the(RR)-P-QPt and(SS)-M-QPt, specific P-and M-configurations were effectively induced from intrinsic chiral carbon centres(R or S), ingeniously avoiding the racemic mixture formation and chiral separation. Furthermore, the chirality originating from both chiral carbon centres and helicene-like structure improves the g factor significantly, which provides a new molecular design strategy for chiral Pt(II) enantiomers with good CPL properties.

Liver function, blood ammonia leveland portosystemic gradient (PSG) were compared beforeand after the procedure. Patency of shunt was followed byportography every 7 days after ***: DIPS was successfully established in all 10 swinewithout any complications. One day alter procedure thealanine aminotransferase (ALT), aspartate aminotransferase(AST), and blood ammonia level (BAL) of swine rose from5.40±0.69, 16.00+0.79 and 35.66+4.10 to 34.20±3.46,59.70±2.22 and 66.94±3.44 respectively. (P＜0.05). The PSGdecreased from 0.59±0.20 kPa to 0.24±0.11 kPa after DIPS(P＜0.05). The shunt of 10 swine was kept patent from 7-28days (median patency time was 14 days).CONCLUSION: This initial experience demonstrated thatcreating intrahepatic portacaval shunt from retrohepaticsegment of IVC to portal vein with puncture undersonographic guidance in swine is safe and feasible. Furtherstudies are necessary to perform DIPS in cirrhosis patients.

AIM To evaluate the safety and efficacy of combined endovascular brachytherapy(EVBT),transarterial chemoembolization(TACE),and sorafenib to treat hepatocellular carcinoma(HCC) patients with main portal vein tumor thrombus(MPVTT).METHODS This single-center retrospective study involved 68 patients with unresectable HCC or those who were unfit for liver transplantation and percutaneous frequency ablation according to the BCLC classification. All patients had Child-Pugh classification grade A or B,Eastern Cooperative Oncology Group(ECOG)performance status of 0-2,and MPVTT. The patients received either EVBT with stent placement,TACE,and sorafenib(group A,n = 37),or TACE with sorafenib(group B,n = 31). The time to progression(TTP) and overall survival(OS) were evaluated by propensity score *** In the entire cohort,the 6-,12-,and 24-mo survival rates were 88.9%,54.3%,and 14.1% in group A,and 45.8%,0%,and 0% in group B,respectively(P < 0.001). The median TTP and OS were significantly longer in group A than group B(TTP: 9.0 mo vs 3.4 mo,P < 0.001; OS: 12.3 mo vs 5.2 mo,P < 0.001). In the propensity score-matched cohort,the median OS was longer in group A than in group B(10.3 mo vs 6.0 mo,P < 0.001). Similarly,the median TTP was longer in group A than in group B(9.0 mo vs 3.4 mo,P < 0.001). Multivariate Cox analysis revealed that the EVBT combined with stent placement,TACE,and sorafenib strategy was an independent predictor of favorable OS(HR = 0.18,P < 0.001). CONCLUSION EVBT combined with stent placement,TACE,and sorafenib might be a safe and effective palliative treatment option for MPVTT.

AIM: Clinical application and potential complication of percutaneous transsplenic varices embolization (PTSVE) of esophageal or gastrio-fundal varices in patients with hepatocellular carcinoma (HCC) complicated with portal vein cancerous thrombosis (PVCT).METHODS: 18 patients with HCC complicated with PVCT and esophageal or gastrio-fundal varices who underwent PTSVE were collected. The rate of success, complication, mortality of the procedure and postoperative complication were recorded and analyzed.RESULTS: PTSVE were successfully performed in 16 of 18cases, and the rate of success was 89%. After therapy erythrocyte counts decreased in all of the natunts. 5 of patients needed blood transfusion, 2 patients requiredsurgical intervention because of and 11 patients with ascites were alleviated by diuresis. Among these 18patients, the procedure-related mortality was 11% (2/18),one died of acute hepatic failure on the forth day after procedure, another died of acute renal failure on the fifth day. The patients were follow up for 112 mon exceptone. 13of them died of their tumors but none of them experienced variceal bleeding.CONCLUSION: PTSVE is a relatively safe and effective method to treat esophageal or gastrio-fundal varices in HCCpatients with PVCT when percutaneous transhepatic varices embolization (PTHVE) of varices is impossible.
