Portal venous system thrombosis (PVST), a common complication of liver cirrhosis, is closely associated with thrombophilia. To explore the association of homocysteine (Hcy), anticardiolipin antibody (aCL), and anti-β2 glycoprotein I antibody (aβ2GPI), which are possible thrombophilic factors, with PVST in liver cirrhosis. Overall, 654 non-malignant patients (219 with and 435 without liver cirrhosis) admitted between January 2016 and June 2020 were retrospectively evaluated. Presence of PVST, degree of main portal vein (MPV) thrombosis, and clinically significant PVST were identified. Hcy level, hyperhomocysteinemia (HHcy), aCL positivity, and aβ2GPI positivity were compared according to the presence of liver cirrhosis and PVST. Positive aβ2GPI was significantly more frequent in patients with liver cirrhosis than those without, but Hcy level and proportions of HHcy and positive aCL were not significantly different between them. PVST could be evaluated in 136 cirrhotic patients. Hcy level [10.57 μmol/L (2.71-56.82) versus 9.97 μmol/L (2.05-53.44); P = 0.796] and proportions of HHcy [4/44 (9.1%) versus 13/81 (16.0%); P = 0.413] and positive aCL [1/23 (4.3%) versus 10/52 (19.2%); P = 0.185] and aβ2GPI [9/23 (39.1%) versus 21/52 (40.4%); P = 0.919] were not significantly different between cirrhotic patients with and without PVST. There was still no significant association of Hcy level, HHcy, aCL, or aβ2GPI with PVST based on Child-Pugh classification, MPV thrombosis >50%, and clinically significant PVST. Hcy, aCL, and aβ2GPI may not be associated with PVST in liver cirrhosis, suggesting that routine screening for Hcy, aCL, and aβ2GPI should be unnecessary in such patients.

Clinical Differential Diagnosis

Portal vein thrombosis (PVT) can be chronic or acute in nature; it is characterized by a thrombus formation in the main portal vein and/or its right or left branches. Herein, we present a 36-year-old woman with asymptomatic noncirrhotic chronic PVT who developed preeclampsia in the later stage of pregnancy. This report will emphasize the clinical differential diagnosis, outcome, and management of pregnancies complicated by noncirrhotic PVT.

INTRODUCTION: There is no study relating magnetic resonance imaging (MRI) to ultrasound (US) findings in patients with Schistosomiasis mansoni. Our aim was to describe MRI findings inpatients with schistosomal liver disease identified by US. METHODS: Fifty-four patients (mean age 41.6±13.5years) from an area endemic for Schistosomiasis mansoni were selected for this study.All had US indicating liver schistosomal fibrosis and were evaluated with MRI performed witha 1.5-T superconducting magnet unit (Sigma). RESULTS: Forty-seven (87%) of the 54 patientsshowing signs of periportal fibrosis identified through US investigation had confirmed diagnosesby MRI. In the seven discordant cases (13%), MRI revealed fat tissue filling in the hilar periportalspace where US indicated isolated thickening around the main portal vein at its point of entryto the liver. We named this the fatty hilum sign. One of the 47 patients with MRI evidence ofperiportal fibrosis had had his gallbladder removed previously. Thirty-five (76.1%) of the other46 patients had an expanded gallbladder fossa filled with fat tissue, whereas MRI of the remainingeleven showed pericholecystic signs of fibrosis. CONCLUSIONS: Echogenic thickening of thegallbladder wall and of the main portal vein wall heretofore attributed to fibrosis were frequentlyidentified as fat tissue in MRI. However, the gallbladder wall thickening shown in US (expandedgallbladder fossa in MRI) is probably secondary to combined hepatic morphologic changes inschistosomiasis, representing severe liver involvement.

Background: Spontaneous portosystemic shunts (SPSS) are one of the hallmarks of Budd-Chiari syndrome (BCS). Ultrasound can accurately show the location and type of portosystemic collaterals. Objectives: To study the sonographic feature of SPSS in patients with BCS and to evaluate differences in the main portal vein diameter among multiple types of portosystemic shunts. Patients and Methods: Ultrasonographies of 44 patients with SPSS among 352 BCS patients between June 2000 and November 2015 were reviewed retrospectively. The SPSS in 44 BCS patients were first detected by ultrasound and then confirmed via digital subtraction angiography (DSA), computed tomography angiography (CTA) or magnetic resonance venography (MRV). The location, course, diameter and hemodynamics of the spontaneous portosystemic shunts were observed by ultrasound. In addition, one-way analysis of variance (ANOVA) was performed to evaluate the difference in the main portal vein diameter between the different shunt types. Results: The blood drainage patterns of SPSS in 44 of 352 patients with BCS were classified as the following five types: portal-umbilical shunts (15/44), portal-hepatic shunts (11/44), portal-accessory hepatic shunts (6/44) (the accessory hepatic veins included the inferior right hepatic vein and the caudate lobe vein), splenorenal shunts (8/44) and main portal vein-inferior vena cava shunts (4/44). The corresponding hemodynamics of the five types mentioned above were obtained. Main portal vein-inferior vena cava shunts had a significantly larger mean portal trunk diameter compared with all other types (P < 0.05 for all comparisons). In addition, the mean portal trunk diameters in portal-umbilical shunts and portal-hepatic shunts were obviously larger than that of splenorenal shunts (P < 0.05), while there were no statistically significant differences between the other types. Conclusion: Spontaneous portosystemic shunts are not rare in patients with BCS. Ultrasound is a reliable means for their diagnosis and it offers substantial information for use in clinical treatment.

Critical Portion

Perhaps the most critical portion of the transjugular intrahepatic portosystemic shunt procedure involves obtaining secure portal venous access. An acute angle of entry into the portal venous system during intrahepatic portosystemic shunt creation can make retrograde advancement of a guidewire into the splenic or superior mesenteric vein difficult. However, securing access from the jugular access site to the portal system with a reliable guidewire is of critical importance during the procedure. This chapter presents a technique to advance a flexible-tip guidewire antegrade into right portal vein branches prior to prolapsing the guidewire into the main portal vein to secure transjugular portal venous access.
