Abstract
BACKGROUND Biliary atresia (BA) is the most common indication for pediatric liver trans plantation, although portoenterostomy is usually performed first. However, due to the high failure rate of portoenterostomy, liver transplantation has been advocated as the primary procedure for patients with BA. It is still unclear if a previous portoenterostomy has a negative impact on liver transplantation outcomes. AIM To investigate the effect of prior portoenterostomy in infants un dergoing liver transplantation for BA. METHODS This was a retrospective cohort study of 42 pediatric patients with BA who underwent primary liver transplantation from 2013 to 2023 at a single tertiary center in Brazil. Patients with BA were divided into two groups: Those under going primary liver transplantation without portoenterostomy and those undergoing liver transplantation with prior portoenterostomy. Continuous variables were compared using the Student's t-test or the Kruskal-Wallis test, and categorical variables were compared using the χ2 or Fisher's exact test, as appropriate. Multivariable Cox regression analysis was performed to determine risk factors for portal vein thrombosis. Patient and graft survival analyses were conducted with the Kaplan-Meier product-limit estimator, and patient subgroups were compared using the two-sided log-rank test. RESULTS Forty-two patients were included in the study (25 [60%] girls), 23 undergoing liver transplantation without prior portoenterostomy, and 19 undergoing liver transplantation with prior portoenterostomy. Patients with prior portoenterostomy were older (12 vs 8 months; P = 0.02) at the time of liver transplantation and had lower Pediatric End-Stage Liver Disease scores (13.2 vs 21.4; P = 0.01). The majority of the patients (35/42, 83%) underwent living-donor liver transplantation. The group of patients without prior portoenterostomy appeared to have a higher incidence of portal vein thrombosis (39 vs 11%), but this result did not reach statistical significance. Prior portoenterostomy was not a protective factor against portal vein thrombosis in the multivariable analysis after adjusting for age at liver transplantation, graft-to-recipient weight ratio, and use of vascular grafts. Finally, the groups did not significantly differ in terms of post-transplant survival. CONCLUSION In our study, prior portoenterostomy did not significantly affect the outcomes of liver transplantation.

Abstract
AIM To identify age-matched healthy volunteers, non-cirrhotic chronic liver disease (CLD) and cirrhotic patients based on portal hemodynamic parameters using 4D flow MRI. METHODS A total of 10 age-matched healthy volunteers and 69 CLD patients were enrolled and underwent 4D flow MRI prospectively. 4D flow MR images were processed by an MD in biomedical engineering working on the GTFlow platform. Portal hemodynamic parameters include net flow (mL/cycle), flow volume per second through the lumen (mL/sec), average flow velocity (cm/sec), and maximum flow velocity (cm/sec). The difference in portal hemodynamic parameters of 4D flow MRI was compared among healthy volunteers, non-cirrhotic CLD patients and patients with cirrhosis by one-way ANOVA or Kruskal-Wallis nonparametric test and post hoc tests. RESULTS 10 CLD patients without cirrhosis and 56 patients with cirrhosis were eventually included, along with 10 healthy volunteers who were divided into three groups. 3 patients with cirrhosis whose image quality did not meet the requirements were excluded. There were no significant differences in portal hemodynamic parameters among the three groups except portal average velocity (P > 0.05). There was no statistical difference in all portal hemodynamic parameters of 4D flow MRI between healthy volunteers and patients with cirrhosis (P > 0.05). There were significant differences in portal average velocity between non-cirrhotic CLD patients, healthy volunteers and patients with cirrhosis, respectively (11.44±3.93 vs 8.10±2.66, P=0.013; 11.44±3.93 vs 8.60±2.22, P=0.007). CONCLUSION Portal average velocity obtained by 4D flow MRI can be an auxiliary means to identify cirrhosis in patients with CLD.

Abstract
BACKGROUND It is known that there are varying frequencies of hepatic portal vein branching patterns found in the literature. Studies use different methods and classifications to evaluate the anatomy of the portal vein, which limits accurate comparison between studies and the determination of true frequency of branching patterns in different populations. The aim of the present study was to investigate the intrahepatic branching of the portal vein in corrosive samples using different methods - somatoscopic and computed tomography (CT) and compare with similar studies as well as compare the reclassified data according to the most popular classifications used in the literature. METHODS A total of 105 liver corrosion specimens from the 1960-1980 period (51 male and 54 female individuals; min-max age variation - 21-90 y., M=59,46 y.) were investigated. The branching patterns of the hepatic portal vein (HPV), left (HPV-LB) and right branch of hepatic portal vein (HPV-RB), and their segmental branches were examined and scanned by CT. Standard HPV ramification was considered, when HPV divided into HPV-LB and HPV-RB, HPV-RB bifurcated to the anterior and posterior branches, and further segmental ramification into the superior and inferior branches was considered standard. We compared the HPV main branch length and diameter measurements between manual and CT method. A review of the literature was performed on portal vein branching variations. RESULTS The standard HPV ramification pattern was detected in 85.7% of the cases in both somatoscopic and CT evaluation. Variations related to the main branches were HPV trifurcation - 7.6%, posterior branch of right branch of hepatic portal vein from HPV - 4.8% and 5.7%, HPV quadrifurcation 1.9% and 1% respectively, in somatoscopic and CT evaluation. There was a significant difference between HPV-LB length and diameter in CT and manual measurements. According to the literature, more variations are seen using the CT method versus somatoscopic corrosion cast evaluation. The varying frequency in studies may be explained by a lack of one unanimous classification of branching patterns (some authors do not consider segmental variations as standard HPV ramification) and different evaluation methods. CONCLUSION Somatoscopic evaluation of the branching patterns of the hepatic portal vein in corroded specimens and their CT reconstructions did not differ significantly (which allows relatively accurate comparison of old specimens with newer data). However, the ability to evaluate the reconstructed 3D images of the specimens allowed a more accurate assessment of segmental branching and measurements of lengths and diameters. Standard HPV branching (according to a self-developed classification) in this study was 85.7%. Depending on the classification, the rate of standard branching in the same corrosive samples varied from 63.8% to 84.8% of all cases, indicating that the lack of a unified and stable classification makes it difficult to compare the results of different studies. Deviations from standard branching are very important in surgical procedures and liver transplantation.

Abstract
Splanchnic vein thrombosis includes Budd-Chiari syndrome and portal vein thrombosis. These diseases share common features: (i) they are rare diseases and (ii) they can lead to portal hypertension and its complications. Budd-Chiari syndrome and portal vein thrombosis in the absence of underlying liver disease share many risk factors, the most common being myeloproliferative neoplasms. A rapid and comprehensive workup for thrombosis risk factors is necessary in these patients. Long-term anticoagulation is indicated in most patients. Portal vein thrombosis can also develop in patients with cirrhosis, and is associated with a worse course of cirrhosis. Indications for anticoagulation in patients with cirrhosis are increasing. Transjugular intrahepatic portosystemic shunt is a second-line procedure in this setting. Because of the rarity of these diseases, high-level evidence studies are rare. However, collaborative studies have provided a better understanding of their natural history and allowed to improve the management of these patients. This review focuses on the causes, diagnosis, and management of patients with Budd-Chiari syndrome, patients with portal vein thrombosis without underlying liver disease, and patients with cirrhosis and portal vein thrombosis.

Abstract
BACKGROUND In two-stage hepatectomy for bilobar liver metastases from colorectal cancer, future liver remnant (FLR) growth can be achieved using several techniques, such as right portal vein ligation (RPVL) or right portal vein embolization (RPVE). A few heterogeneous studies have compared these two techniques with contradictory results concerning FLR growth. The objective of this study was to compare FLR hypertrophy of the left hemi-liver after RPVL and RPVE. STUDY DESIGN This was a retrospective comparative study using a propensity score of patients who underwent RPVL or RPVE prior to major hepatectomy between January 2010 and December 2020. The endpoints were FLR growth (%) after weighting using the propensity score, which included FLR prior to surgery and the number of chemotherapy cycles. Secondary endpoints were the percentage of patients undergoing simultaneous procedures, the morbidity and mortality, the recourse to other liver hypertrophy procedures, and the number of invasive procedures for the entire oncologic program in intention-to-treat analysis. RESULTS Fifty-four consecutive patients were retrospectively included and analyzed, 18 in the RPVL group, and 36 in the RPVE group. The demographic characteristics were similar between the groups. After weighting, there was no significant difference between the RPVL and RPVE groups for FLR growth (%), respectively 32.5% [19.3-56.0%] and 34.5% [20.5-47.3%] (p = 0.221). There was no significant difference regarding the secondary outcomes except for the lower number of invasive procedures in RPVL group (median of 2 [2.0, 3.0] in RPVL group and 3 [3.0, 3.0] in RPVE group, p = 0.001)). CONCLUSION RPVL and RPVE are both effective to provide required left hemi-liver hypertrophy before right hepatectomy. RPVL should be considered for the simultaneous treatment of liver metastases and the primary tumor.

Abstract
BACKGROUND Iatrogenic portal vein (PV) injuries following pleural drainage catheter (PDC) insertion are rare but life-threatening. This case report emphasizes the importance of prompt recognition and effective interventional radiology (IR) management. CASE PRESENTATION A 38-year-old Asian male, admitted for a non-ST-segment elevation myocardial infarction, suffered a critical PV injury during PDC insertion, leading to rapid clinical deterioration. The IR team conducted a portogram, retrieved the catheter, and successfully executed an embolization procedure. The patient's recovery, confirmed through imaging and improving liver function tests, enabled discharge with follow-up instructions. CONCLUSIONS This case highlights the clinical significance of promptly recognizing and effectively managing iatrogenic PV injuries during PDC insertion, with the pivotal role of IR. Collaboration between IR and surgical teams is crucial for optimizing patient outcomes.

Abstract
BACKGROUND Pancreatic cancer in contact with the superior mesenteric vein/portal vein is classified as resectable pancreatic cancer; however, the biological malignancy and treatment strategy have not been clarified. METHODS Data from 186 patients who underwent pancreatectomy for pancreatic cancer were evaluated using a prospectively maintained database. The patients were classified as having resectable tumors without superior mesenteric vein/portal vein contact and with superior mesenteric vein/portal vein contact of ≤180°. Disease-free survival, overall survival, and prognostic factors were analyzed. RESULTS In the univariate analysis, superior mesenteric vein/portal vein contact in resectable pancreatic cancer was a significant prognostic index for disease-free survival and overall survival. In the multivariate analysis for poor disease-free survival, the superior mesenteric vein/portal vein contact remained significant (hazard ratio = 2.13, 95% confidence interval: 1.29-3.51; p < 0.01). In the multivariate analysis, superior mesenteric vein/portal vein contact was a significant independent prognostic index for overall survival (hazard ratio = 2.17, 95% confidence interval: 1.27-3.70; p < 0.01), along with sex, tumor differentiation, nodal involvement, and adjuvant chemotherapy. Portal vein resection for superior mesenteric vein/portal vein contact did not improve the overall survival (p = 0.86). CONCLUSIONS Superior mesenteric vein/portal vein contact in resectable pancreatic cancer was found to be an independent predictor of disease-free survival and overall survival after elective resection. Thus, pancreatic cancer in contact with the superior mesenteric vein/portal vein may be considered as borderline resectable pancreatic cancer.

Abstract
Duplication of the portal vein is a rare variation, and reports of this condition are quite limited. The present report describes a woman of advanced age who was incidentally diagnosed with duplicated portal veins. The portal vein from the splenic vein distributed to the left lobe of the liver, and that from the superior mesenteric vein ran between the pancreas and duodenum to distribute to the right lobe. The former portal vein connected with the round ligament, and its presumptive origin was the left vitelline vein. The latter was presumably from the right vitelline vein. Between the 2 portal veins, 2 anastomotic veins were identified; one anastomosis was posterior to the pancreatic head, and the other was intrahepatic. The common bile duct was located posterolateral to the portal veins. The relationships of these veins to the round ligament and common bile duct support the reverse rotation hypothesis of the duodenum in the development of portal vein variations.

Abstract
BACKGROUND Heart failure (HF) causes extracardiac organ congestion, including in the hepatic portal system. Reducing venous congestion is essential for HF treatment, but evaluating venous congestion is sometimes difficult in patients with chronic HF. The portal vein (PV) flow pattern can be influenced by right atrial pressure. Ultrasound images of the PV are quite easy to obtain and are reproducible among sonographers. However, the association between PV pulsatility and the condition of HF remains unclear. We hypothesize that PV pulsatility at discharge reflects the condition of HF. AIM To evaluate the usefulness of PV pulsatility as a prognostic marker for hospitalized patients with acute HF. METHODS This observational study was conducted from April 2016 to January 2017 and April 2018 to April 2019 at Shinko Hospital. We enrolled 56 patients with acute HF, and 17 patients without HF served as controls. PV flow velocity was measured by ultrasonography on admission and at discharge. We calculated the PV pulsatility ratio (PVPR) as the ratio of the difference between the peak and minimum velocity to the peak velocity. The primary endpoint was cardiac death and HF re-hospitalization. The observation period was 1 year from the first hospitalization. The Kaplan-Meier method was used to determine the stratified composite event-free rates, and the log-rank test was used for comparisons between groups. RESULTS On admission, the PVPR was significantly higher in patients with acute HF than controls (HF: 0.29 ± 0.20 vs controls: 0.08 ± 0.07, P < 0.01). However, the PVPR was significantly decreased after the improvement in HF (admission: 0.29 ± 0.20 vs discharge: 0.18 ± 0.15, P < 0.01) due to the increase in minimum velocity (admission: 12.6 ± 4.5 vs discharge: 14.6 ± 4.6 cm/s, P = 0.03). To elucidate the association between the PVPR and cardiovascular outcomes, the patients were divided into three groups according to the PVPR tertile at discharge (PVPR-T1: 0 ≤ PVPR ≤ 0.08, PVPR-T2: 0.08 < PVPR ≤ 0.21, PVPR-T3: PVPR > 0.21). The Kaplan-Meier analysis showed that patients with a higher PVPR at discharge had the worst prognosis among the groups. CONCLUSION PVPR at discharge reflects the condition of HF. It is also a novel prognostic marker for hospitalized patients with acute HF.

Abstract
BACKGROUND Left-sided portal hypertension including gastric venous congestion may be caused by ligating the splenic vein during pancreaticoduodenectomy with portal vein resection or total pancreatectomy. The usefulness of reconstruction with the splenic vein has been reported in such cases. However, depending on the site of the tumor and other factors, it may be impossible to leave sufficient length of the splenic vein, making anastomosis difficult. We report two patterns of reconstruction with the right gastroepiploic vein during pancreaticoduodenectomy and total pancreatectomy to prevent left-sided portal hypertension. CASE PRESENTATION The first patient was a 79-year-old man who underwent pancreaticoduodenectomy for pancreatic cancer. The root of the splenic vein was infiltrated by the tumor, and we resected this vein at the confluence of the portal vein. Closure of the portal vein was performed without reconstruction of the splenic vein. To prevent left-sided portal hypertension, we anastomosed the right gastroepiploic vein to the middle colic vein. Postoperatively, there was no suggestion of left-sided portal hypertension, such as splenomegaly, varices, and thrombocytosis. The second case was a 63-year-old woman who underwent total pancreatectomy for pancreatic cancer. The splenic vein-superior mesenteric vein confluence was infiltrated by the tumor, and we resected the portal vein, including the confluence. End-to-end anastomosis was performed without reconstruction of the splenic vein. We also divided the left gastric vein, left gastroepiploic vein, right gastroepiploic vein, and right gastric vein, which resulted in a lack of drainage veins from the stomach and severe gastric vein congestion. We anastomosed the right gastroepiploic vein to the left renal vein, which improved the gastric vein congestion. Postoperatively, imaging confirmed short-term patency of the anastomosis site. Although the patient died because of tumor progression 8 months after the surgery, no findings suggested left-sided portal hypertension, such as varices. Reconstruction with the right gastroepiploic vein during pancreaticoduodenectomy and total pancreatectomy is useful to prevent left-sided portal hypertension.

Abstract
BACKGROUND Right ventricle dysfunction is common after corrective surgery for tetralogy of Fallot and is associated with significant morbidity and mortality. We aimed to determine whether an increased portal vein pulsatility fraction (PVPF) was associated with worse clinical outcomes. METHODS In a prospective, observational, single-centre study, PVPF and other commonly used parameters of right ventricle function were assessed in patients of all ages undergoing corrective surgery for tetralogy of Fallot intraoperatively, with transesophageal echocardiography, before and after bypass, and post-operatively, with transthoracic echocardiography, at days 1, 2, at extubation, and at ICU discharge. The correlation was tested between PVPF and mechanical ventilation duration, prolonged ICU stay, mortality, and right ventricle function. RESULTS The study included 52 patients, and mortality was in 3 patients. PVPF measurement was feasible in 96% of the examinations. PVPF in the immediate post-operative period had sensitivity of 73.3% and a specificity of 74.3% in predicting the occurrence of the composite outcome of prolonged mechanical ventilation, ICU stay, or mortality. There was a moderate negative correlation of PVPF with right ventricle fractional area change and right ventricle global longitudinal strain (r = -0.577, p < 0.001 and r = 0.465, p < 0.001, respectively) and a strong positive correlation with abnormal hepatic vein waveform (rho = 0.749, p < 0.001). CONCLUSION PVPF is an easily obtainable bedside parameter to assess right ventricular dysfunction and predict prolonged mechanical ventilation, prolonged ICU stay, and mortality.

Abstract
PURPOSE Portal vein (PV) reconstruction is a key factor for successful living-donor liver transplantation (LDLT). Anatomical variations of right PV (RPV) are encountered among potential donors. METHODS To evaluate a single center experience of reconstruction techniques for the right hemi-liver grafts with PV variations during the period between May 2004 and 2022. RESULTS A total of 915 recipients underwent LDLT, among them 52 (5.8%) had RPV anatomical variations. Type II PV was found in 7 cases (13.5%), which were reconstructed by direct venoplasty. Type III PV was found in 27 cases (51.9%). They were reconstructed by direct venoplasty in 2 cases (3.8%), Y graft interposition in 2 cases (3.8%), and in situ double PV anastomoses in 23 cases (44.2%). Type IV PV was found in 18 cases (34.6%) and was reconstructed by Y graft interposition in 9 cases (17.3%), and in situ double PV anastomoses in 9 cases (17.3%). Early right posterior PV stenosis occurred in 2 recipients (3.8%). Early PV thrombosis occurred in 3 recipients (5.8%). The median follow-up duration was 54.5 months (4 - 185). The 1-, 3-, and 5-years survival rates were 91.9%, 86%, and 81.2%, respectively. Late PV stenosis occurred in 2 recipients (3.8%) and was managed conservatively. CONCLUSION Utilization of potential living donors with RPV anatomic variations may help to expand the donor pool. We found that direct venoplasty and in situ dual PV anastomoses techniques were safe, feasible, and associated with successful outcomes.

Abstract
In dairy cows, the liver supports the increased nutrient demands of the udder for milk production. Blood flow is key for the transport of these nutrients. This study investigated portal vein blood flow volume (PVBFVol) in relation to daily milk yield (DMY), milk vein blood flow volume (MVBFVol) and body condition parameters of high-producing dairy cows, starting from late lactation, throughout dry period, and consecutive early lactation. Seventeen repeated examinations were performed on 19 Holstein cows and 313 measurement days were finally included. Vein morphology and blood flow were examined via B-mode and spectral Doppler (triplex) ultrasonography, respectively. Body condition parameters recorded were body condition score (BCS), backfat thickness (BFT) measurement with ultrasonography, heart girth circumference (HG) and withers height (WH). Longitudinal relationship of PVBFVol with MVBFVol, DMY, BCS, BFT, HG and WH was analyzed with linear mixed models, with random intercept effects, using restricted cubic splines. A significant increase of 8.28% (p < 0.01) in PVBFVol appeared for every 1 L/min increase in MVBFVol in the univariable model. PVBFVol presented a significant negative association with BCS (p < 0.01) and BFT (p = 0.02), while interaction with production stage was significant, too. PVBFVol significantly increased by 0.38% (p = 0.04) for every 1 kg increase in DMY in the multivariable model. In conclusion, the increased PVBFVol during lactation accompanies the escalation in metabolic activity of the liver and the increased blood circulation through the udder, coping with the udder's escalating nutrient demands for milk synthesis.

Abstract
BACKGROUND Porto-mesenteric vein (PMV) infiltration of pancreatic cancer is classified as borderline resectable cancer. For en-bloc resectability, the probability of PMV resection and reconstruction is the most decisive factor. The purpose of this study was to compare and analyze PMV resection and reconstruction during pancreatic cancer surgery using end-to-end anastomosis (EA) and a cryopreserved allograft (AG) and to verify the effectiveness of reconstruction using an AG. METHODS Between May 2012 and June 2021, 84 patients (65 underwent EA, and 19 received AG reconstruction) underwent pancreatic cancer surgery with PMV reconstruction. An AG is a cadaveric graft with a diameter of 8-12 mm and is obtained from a liver transplant donor. Patency after reconstruction, disease recurrence, overall survival, and perioperative factors were assessed. RESULTS The median age was higher in EA patients (p = .022) and neoadjuvant therapy (p = .02) was more in AG patients. Upon histopathological examination, the R0 resection margin did not show a significant difference by reconstruction method. During a 36-month survival analysis, primary patency was significantly superior in EA patients (p = .004), and there was no significant difference in recurrence-free survival (p = .628) or overall survival (p = .638) rates. CONCLUSION Compared with EA, AG reconstruction after PMV resection during pancreatic cancer surgery showed a lower primary patency, but there was no difference in recurrence-free or overall survival rates. Therefore, the use of AG can be a viable option for borderline resectable pancreatic cancer surgery if the patient is properly followed-up postoperatively.

Abstract
OBJECTIVE To develop and evaluate task-based radiomic features extracted from the mesenteric-portal axis for prediction of survival and response to neoadjuvant therapy in patients with pancreatic ductal adenocarcinoma (PDAC). METHODS Consecutive patients with PDAC who underwent surgery after neoadjuvant therapy from two academic hospitals between December 2012 and June 2018 were retrospectively included. Two radiologists performed a volumetric segmentation of PDAC and mesenteric-portal axis (MPA) using a segmentation software on CT scans before (CTtp0) and after (CTtp1) neoadjuvant therapy. Segmentation masks were resampled into uniform 0.625-mm voxels to develop task-based morphologic features (n = 57). These features aimed to assess MPA shape, MPA narrowing, changes in shape and diameter between CTtp0 and CTtp1, and length of MPA segment affected by the tumor. A Kaplan-Meier curve was generated to estimate the survival function. To identify reliable radiomic features associated with survival, a Cox proportional hazards model was used. Features with an ICC ≥ 0.80 were used as candidate variables, with clinical features included a priori. RESULTS In total, 107 patients (60 men) were included. The median survival time was 895 days (95% CI: 717, 1061). Three task-based shape radiomic features (Eccentricity mean tp0, Area minimum value tp1, and Ratio 2 minor tp1) were selected. The model showed an integrated AUC of 0.72 for prediction of survival. The hazard ratio for the Area minimum value tp1 feature was 1.78 (p = 0.02) and 0.48 for the Ratio 2 minor tp1 feature (p = 0.002). CONCLUSION Preliminary results suggest that task-based shape radiomic features can predict survival in PDAC patients. KEY POINTS • In a retrospective study of 107 patients who underwent neoadjuvant therapy followed by surgery for PDAC, task-based shape radiomic features were extracted and analyzed from the mesenteric-portal axis. • A Cox proportional hazards model that included three selected radiomic features plus clinical information showed an integrated AUC of 0.72 for prediction of survival, and a better fit compared to the model with only clinical information.

Abstract
PURPOSE To evaluate the safety and efficacy of percutaneous interventional treatment of portal vein stenosis in children. MATERIAL AND METHODS A retrospective analysis of all interventional treatments for portal vein stenosis in pediatric patients at a single institution from 2010 to 2021 was conducted. Platelet count, spleen size and portal vein flow velocity were assessed during the follow-up period. Primary and primary assisted patency time were determined. RESULTS A total of ten children (median age 28.5 months, interquartile range (IQR): 2.75-52.5 months) with portal vein stenosis after Mesorex-Shunt (n = 4), liver transplantation (n = 3) and other etiologies (n = 3) underwent 15 interventional procedures. There were five reinterventions and one discontinued intervention. The technical success rate was 93.3% (14/15) and clinical success of treated patients was 100% (14/14). Median follow-up was 18 months (IQR: 13.5-81 months). The median primary patency time for stent placement was 70 months (IQR: 13.5-127.25 months). For balloon angioplasty, the median primary patency time was 9 months (IQR 7.25-11.5 months), while the median assisted primary patency time was 14 months (IQR: 12 to 15 months). Platelet count, spleen size and portal vein flow velocity reliably corresponded to recurrence of portal vein stenosis in asymptomatic patients during follow-up. CONCLUSION Interventional treatment is a safe and efficient method to treat portal vein stenosis with long patency times, regardless of etiology. Primary stent placement shows a higher primary patency time than balloon angioplasty. Implementation of stent placement as the primary interventional method may improve patency times and reduce the need for repeat reinterventions in pediatric patients.

Abstract
Double portal veins are a duplication of the portal vein and normal portal vein with an accessory portal vein. We report a case of a 63-year-old asymptomatic female with double portal veins. There was fat accumulation observed in the area which was supplied by the first portal vein in normal position, and fatty sparing of the liver was observed in the area which was supplied by the second portal vein in the preduodenal position. The 2 portal veins were equal in size. Furthermore, the patient presented with multiple congenital anomalies, including double inferior vena cava, splenic lobulation, and accessory liver lobe. Therefore, double portal veins in our case were thought to be an incomplete duplication of the portal vein with multiple congenital anomalies.

Abstract
PURPOSE The purpose of this work was to establish normal reference values for 4D flow MRI-derived flow, velocity, and vessel diameters, and to define characteristic flow patterns in the portal venous system of healthy adult subjects. METHODS For this retrospective study, we screened all available 4D flow MRI exams of the upper abdomen in healthy adults acquired at our institution between 2012 and 2022 at either 1.5 T or 3.0 T MRI after ≥ 5 h fasting. Flow, velocity, and effective diameter were quantified in the 8 planes in the portal venous system (splenic vein, superior mesenteric vein, main, right, and left portal veins). Vessel delineation was manually adjusted over time. Reference ranges for were defined as the mean ± 2 standard deviations. Three readers noted helical and vortical flow on time-resolved pathline visualizations. Conservation of mass flow analysis was performed for quality assurance. RESULTS We included 44 healthy subjects (26 female, 18-74 years) in the analysis. We report reference values for mean and peak flow, mean velocity, and vessel diameter in the healthy portal vein using 4D flow MRI. Normal flow patterns in the portal vein included faint helical (66%) or linear flow (34%). Conservation of mass analysis demonstrated a relative error of 1.1 ± 4.6% standard deviation (SD) at the splenomesenteric confluence and - 1.4 ± 4.1% SD at the portal bifurcation. CONCLUSION We have reported normal hemodynamic values that are necessary baseline data for emerging clinical applications of 4D flow MRI in the portal venous system. Results are consistent with previously published values from smaller cohorts.

Abstract
BACKGROUND The hypereosinophilic syndrome (HES) is a group of rare blood disorders characterized by persistent eosinophilia and damage to multiple organs. HES can be either primary, secondary or idiopathic. Secondary HES are commonly caused by parasitic infections, allergic reactions or cancer. We described a pediatric case of HES associated with liver damage and multiple thrombi. A 12-year-old boy with eosinophilia was complicated with severe thrombocytopenia, liver damage, portal vein, splenic vein, and superior mesenteric vein thromboses. The thrombi recanalized after treatment with methylprednisolone succinate and low molecular weight heparin. No side effects appeared after 1-month. CONCLUSIONS Corticosteroids should be used at an early stage of HES to prevent further damage to vital organs. Anticoagulants should be recommended only in cases with thrombosis which should be actively screened as a part of evaluation of end organ damage.

Abstract
BACKGROUND Some patients with liver cancer lose the chance to have surgical treatment due to insufficient future remnant liver. To address this problem, individual or occlusion of both the portal vein and the bile duct was used to achieve quick hypertrophy. This is the first study reported in which simultaneous ligation of the portal vein and the bile duct was applied as the first step of planned hepatectomy of primary liver cancer. CASE PRESENTATION Here we report a case of a 38-year-old Asian male patient with hepatocellular carcinoma with tumor thrombus in the right anterior branch of the portal vein. Right hemihepatectomy can be curative, but patients face a high risk of liver failure because of the small volume of the remaining left liver lobe. Hence we developed a two-step liver resection strategy in which the patient underwent laparoscopic simultaneous bile duct and portal vein ligation of the right hepatic lobe prior to right hemihepatectomy under laparoscopy. Using this procedure, we achieved fast hypertrophy of the left liver lobe and successfully reversed the primary unresectability. CONCLUSION This case report demonstrates that simultaneous bile duct and portal vein ligation may be a feasible option for those patients with liver cancer who cannot get surgical treatment due to insufficient future remnant liver.

Abstract
Inferior mesenteric vein thrombophlebitis is an uncommon condition. Most cases of portal-mesenteric thrombophlebitis affect either the portal vein or superior mesenteric vein; it is not known why the inferior mesenteric vein is less affected. Thrombophlebitis typically occurs following inflammatory intra-abdominal processes, such as diverticulitis. Diverticulitis is a common condition in the Western world, with several common complications, such as fistula formation and bowel wall perforation. However, although diverticulitis is a common cause of portal-mesenteric thrombophlebitis, thrombophlebitis is still a rare complication of diverticulitis. We present a case of diverticulitis complicated with interior mesenteric vein thrombophlebitis with gas extension into the portal vein.

Abstract
BACKGROUND AND AIMS The aim was to establish a liver venous deprivation (LVD) model in rats, compare hepatic hypertrophy between LVD and associated liver partition and portal vein ligation for staged hepatectomy (ALPPS), and explore the underlying mechanisms. METHODS The LVD or extended-LVD (e-LVD) group received portal vein ligation (PVL) combined with hepatic vein ligation (HVL). The ALPPS or e-ALPPS group received PVL plus parenchyma ligation. Liver regeneration was assessed by measuring the liver weight and performing pathological analysis. Liver functions and the sphingosine kinase 1 (SPHK1)/sphingosine-1-phosphate (S1P)/sphingosine-1-phosphate receptor 1 (S1PR1) pathway were also investigated. RESULTS All future liver remnants (FLRs) in the ALPPS, e-ALPPS, LVD, and e-LVD groups exhibited significant hypertrophy compared with the control group. The LVD and e-LVD procedures induced similar liver hypertrophy than that in the corresponding ALPPS groups. Furthermore, the LVD and e-LVD methods led to obvious cytolysis in the venous-deprived lobes as well as a noticeable increase in serum transaminase levels, while no necrosis was observed in the ALPPS and e-ALPPS groups. SPHK1/S1P/S1PR1 pathway were distinctly activated after operation, especially in congestive/ischemic livers. CONCLUSIONS We describe the first rat model of LVD and e-LVD with simultaneously associated HVL and PVL. Compared with the ALPPS technique, the LVD or e-LVD procedure had a comparable overall effect on the hypertrophy response and a stronger effect on liver function. The SPHK1/S1P/S1PR1 pathway was involved in the LVD- or ALPPS-induced liver remodeling.

Abstract
BACKGROUND Pancreaticoduodenectomy combined with portal vein (PV) and/or superior mesenteric vein (SMV) resection in patients with pancreaticobiliary malignancy has become a common surgical procedure. There are various grafts currently used for PV and/or SMV reconstruction, but each of these grafts have certain limitations. Therefore, it is necessary to explore novel grafts that have an extensive resource pool, are low cost with good clinical application, and are without immune response rejection or additional damage to patients.
AIM To observe the anatomical and histological characteristics of the ligamentum teres hepatis (LTH) and evaluate PV/SMV reconstruction using an autologous LTH graft in pancreaticobiliary malignancy patients.
METHODS In 107 patients, the post-dilated length and diameter in resected LTH specimens were measured. The general structure of the LTH specimens was observed by hematoxylin and eosin (HE) staining. Collagen fibers (CFs), elastic fibers (EFs), and smooth muscle (SM) were visualized by Verhoeff-Van Gieson staining, and the expression of CD34, factor VIII-related antigen (FVIIIAg), endothelial nitric oxide synthase (eNOS), and tissue type plasminogen activator (t-PA) were detected using immunohistochemistry in LTH and PV (control) endothelial cells. PV and/or SMV reconstruction using the autologous LTH was conducted in 26 patients with pancreaticobiliary malignancies, and the outcomes were retrospectively analyzed.
RESULTS The post-dilated length of LTH was 9.67 ± 1.43 cm, and the diameter at a pressure of 30 cm H2O was 12.82 ± 1.32 mm at the cranial end and 7.06 ± 1.88 mm at the caudal end. Residual cavities with smooth tunica intima covered by endothelial cells were found in HE-stained LTH specimens. The relative amounts of EFs, CFs and SM in the LTH were similar to those in the PV [EF (%): 11.23 ± 3.40 vs 11.57 ± 2.80, P = 0.62; CF (%): 33.51 ± 7.71 vs 32.11 ± 4.82, P = 0.33; SM (%): 15.61 ± 5.26 vs 16.74 ± 4.83, P = 0.32]. CD34, FVIIIAg, eNOS, and t-PA were expressed in both LTH and PV endothelial cells. The PV and/or SMV reconstructions were successfully completed in all patients. The overall morbidity and mortality rates were 38.46% and 7.69%, respectively. There were no graft-related complications. The postoperative vein stenosis rates at 2 wk, 1 mo, 3 mo and 1 year were 7.69%, 11.54%, 15.38% and 19.23%, respectively. In all 5 patients affected, the degree of vascular stenosis was less than half of the reconstructed vein lumen diameter (mild stenosis), and the vessels remained patent.
CONCLUSION The anatomical and histological characteristics of LTH were similar to the PV and SMV. As such, the LTH can be used as an autologous graft for PV and/or SMV reconstruction in pancreaticobiliary malignancy patients who require PV and/or SMV resection.

Abstract
BACKGROUND Recently, stem cell therapy has been extensively studied as a promising treatment for decompensated liver cirrhosis (DLC). Technological advances in endoscopic ultrasonography (EUS) have facilitated EUS-guided portal vein (PV) access, through which stem cells can be precisely infused.
AIM To investigate the feasibility and safety of fresh autologous bone marrow injection into the PV under EUS guidance in patients with DLC.
METHODS Five patients with DLC were enrolled in this study after they provided written informed consent. EUS-guided intraportal bone marrow injection with a 22G FNA needle was performed using a transgastric, transhepatic approach. Several parameters were assessed before and after the procedure for a follow-up period of 12 mo.
RESULTS Four males and one female with a mean age of 51 years old participated in this study. All patients had hepatitis B virus-related DLC. EUS-guided intraportal bone marrow injection was performed in all patients successfully without any complications such as hemorrhage. The clinical outcomes of the patients revealed improvements in clinical symptoms, serum albumin, ascites, and Child-Pugh scores throughout the 12-mo follow-up.
CONCLUSION The use of EUS-guided fine needle injection for intraportal delivery of bone marrow was feasible and safe and appeared effective in patients with DLC. This treatment may thus be a safe, effective, non-radioactive, and minimally invasive treatment for DLC.

Abstract
BACKGROUND Portal vein thrombosis (PVT) is a rare complication of acute pancreatitis (AP) and might be associated with worse outcomes. We aimed to study trends, outcomes, and predictors of PVT in AP patients. METHODS The National Inpatient Sample database was utilized to identify the adult patients (≥ 18 years) with primary diagnosis of AP from 2004 to 2013 using International Classification of Disease, Ninth Revision. Patients with and without PVT were entered into propensity matching model based on baseline variables. Outcomes were compared between both groups and predictors of PVT in AP were identified. RESULTS Among the total of 2,389,337 AP cases, 7046 (0.3%) had associated PVT. The overall mortality of AP decreased throughout the study period (p trend ≤ 0.0001), whereas mortality of AP with PVT remained stable (1-5.7%, p trend = 0.3). After propensity matching, AP patients with PVT patients had significantly higher in-hospital mortality (3.3% vs. 1.2%), AKI (13.4% vs. 7.7%), shock (6.9% vs. 2.5%), and need for mechanical ventilation (9.2% vs. 2.5%) along with mean higher cost of hospitalization and length of stay (p < 0.001 for all). Lower age (Odd ratio [OR] 0.99), female (OR 0.75), and gallstone pancreatitis (OR 0.79) were negative predictors, whereas alcoholic pancreatitis (OR 1.51), cirrhosis (OR 2.19), CCI > 2 (OR 1.81), and chronic pancreatitis (OR 2.28) were positive predictors of PVT (p < 0.001 for all) in AP patients. CONCLUSION PVT in AP is associated with significantly higher risk of death, AKI, shock, and need for mechanical ventilation. Chronic and alcoholic pancreatitis is associated with higher risk of PVT in AP.

Abstract
Endoscopic ultrasound (EUS) has expanded its arena from a mere diagnostic modality to an essential therapeutic tool in managing gastrointestinal (GI) diseases. The proximity of the GI tract to the vascular structures in the mediastinum and the abdomen has facilitated the growth of EUS in the field of vascular interventions. EUS provides important clinical and anatomical information related to the vessels' size, appearance and location. Its excellent spatial resolution, use of colour doppler with or without contrast enhancement and ability to provide images “real-time” helps in precision while intervening vascular structures. Additionally, structures such as venous collaterals or varices can be dealt with optimally using EUS. EUS-guided vascular therapy with coil and glue combination has revolutionized the management of portal hypertension. It also helps to avoid radiation exposure in addition to being minimally invasive. These advantages have led EUS to become an upcoming modality to complement traditional interventional radiology in the field of vascular interventions. EUS-guided portal vein (PV) access and therapy is a new kid on the block. EUS-guided portal pressure gradient measurement, injecting chemotherapy in PV and intrahepatic portosystemic shunt has expanded the horizons of endo-hepatology. Lastly, EUS has also forayed into cardiac interventions allowing pericardial fluid aspiration and tumour biopsy with experimental data on access to valvular apparatus. Herein, we provide a comprehensive review of the expanding paradigm of EUS-guided vascular interventions in GI bleeding, portal vein access and its related therapeutic interventions, cardiac access, and therapy. A synopsis of all the technical details involving each procedure and the available data has been tabulated, and the future trends in this area have been highlighted.

Abstract
Despite recent improvements in the diagnosis and treatment of pancreatic cancer (PC), clinical outcomes remain dismal. Moreover, there are no effective prognostic or predictive biomarkers or options beyond carbohydrate antigen 19-9 for personalized and precise treatment. Circulating tumor cells (CTCs), as a member of the liquid biopsy family, could be a promising biomarker; however, the rarity of CTCs in peripheral venous blood limits their clinical use. Because the first venous drainage of PC is portal circulation, the portal vein can be a more suitable location for the detection of CTCs. Endoscopic ultrasound-guided portal venous sampling of CTCs is both feasible and safe. Several studies have suggested that the detection rate and number of CTCs may be higher in the portal blood than in the peripheral blood. CTC counts in the portal blood are highly associated with hepatic metastasis, recurrence after surgery, and survival. The phenotypic and genotypic properties measured in the captured portal CTCs can help us to understand tumor heterogeneity and predict the prognosis of PC. Small sample sizes and heterogeneous CTC detection methods limit the studies to date. Therefore, a large number of prospective studies are needed to corroborate portal CTCs as a valid biomarker in PC.

Abstract
A 56-year-old man presented to our hospital for close examination of a mass in the portal vein. CT showed a homogeneously enhanced mass occupying the portal vein. No other lesions suggestive of a primary tumor were detected. Endoscopic ultrasound-guided fine-needle aspiration revealed that the tumor was pathologically acinar cell carcinoma (ACC) based on the positive staining for both BCL-10 and trypsin. He was diagnosed with an ectopic ACC developed in the portal vein. Because the tumor invaded secondary branches of the right intrahepatic portal vein and the superior mesenteric vein, it was considered surgically un-resectable. Therefore, chemotherapy with gemcitabine plus nab-paclitaxel (GEM + nab-PTX) was started. After 2 courses, CT showed progressive disease, so the regimen was switched to FOLFIRINOX. After starting treatment with FOLFIRINOX, the tumor shrank gradually. After 29 courses, CT scan eventually showed disappearance of the tumor and complete response was achieved. After 34 courses, the chemotherapy was discontinued. Since then, the patient has been recurrence-free for 5 years. Our English literature review yielded 6 cases, including this case, of un-resectable ACC in which complete response was achieved by chemotherapy. Our case suggest that platinum-based regimen might be an effective therapy for un-resectable ACC, including ectopic ACC.

Abstract
Estrogens and their metabolites (EMs) are involved in chronic liver disease and gut microbiota regulates estrogen metabolism, whereas the role of enterogenous EMs in liver disease is still elusive. Because of the extremely low level of EMs in portal serum and the EMs contain multiple pairs of isomers, an accurate determination of portal serum EMs is urgently needed. This study established a quantitative detection method for portal serum EMs and applied to non-alcoholic fatty liver disease (NAFLD) related hepatic fibrosis mice model. The serum was derived with a novel derivatization reagent 4-acetyl aminobenzene sulfonyl chloride, and a UPLC-ESI-MS system was used for quantification of 15 EMs in 120 min. Compared with normal group, the concentrations of E1, E2 in model group were significantly decreased by 4-8 times, all the C2 and C4 substitution products (2-OHE1, 2-OHE2, 2-MeOE1, 4-OHE1, 4-MeOE1, 4-OHE2, 4-MeOE2, 2-MeOE2) were significantly decreased by 2-22 times. However, the C16 and C17 substitution products (E3, 16-epiE3, 17-epiE3, 16-ketoE2) levels were increased by 3-5 times (P < 0.01). This study elucidated the changes of enterogenous EMs which entered the liver via portal vein in NAFLD - related hepatic fibrosis and provided methodological platform for other related studies on estrogen metabolism.

Abstract
BACKGROUND Open pancreaticoduodenectomy (OPD) with portal or superior mesenteric vein resection and reconstruction has been applied in pancreatic cancer patients with tumor infiltration or adherence. However, it is controversial whether laparoscopic pancreaticoduodenectomy (LPD) with major vascular resection and reconstruction is feasible. This study aimed to evaluate the safety and feasibility of LPD with major vascular resection compared with OPD with major vascular resection. METHODS We reviewed data for all pancreatic cancer patients undergoing LPD or OPD with vascular resection at Department of Pancreatic Surgery, Fudan University Shanghai Cancer Center, between February 2018 and May 2022. We compared the preoperative, intraoperative, and postoperative clinicopathological data of the two groups to conduct a comprehensive evaluation of LPD with major vascular resection. RESULTS A total of 63 patients underwent pancreaticoduodenectomy (PD) with portal or superior mesenteric vein resection and reconstruction, including 25 LPDs and 38 OPDs. The LPD group had less intraoperative blood loss (200 vs. 400 mL, P < 0.001), lower proportion of intraoperative blood transfusion (16.0% vs. 39.5%, P = 0.047), longer operation time (390 vs. 334 min, P = 0.004) and shorter postoperative hospital stay (11 vs. 14 days, P = 0.005). There was no perioperative death in all patients. There was no significant difference in the incidence of total postoperative complications, grade B/C postoperative pancreatic fistula, delayed gastric emptying and abdominal infection between the two groups. No postpancreatectomy hemorrhage nor bile leakage occurred during perioperative period. There was no significant difference in R0 resection rate and number of lymph nodes harvested between the two groups. Patency of reconstructed vessels in the two groups were 96.0% and 92.1%, respectively (P = 0.927). CONCLUSIONS LPD with portal or superior mesenteric vein resection and reconstruction was safe, feasible and oncologically acceptable for selected patients with pancreatic cancer, and it can achieve similar or even better perioperative results compared to open approach.

Abstract
OBJECTIVES To investigate the value of contrast-enhanced portal vein imaging at the hepatobiliary phase obtained with gadobenate dimeglumine for predicting clinical outcomes in patients with chronic liver disease (CLD). METHODS Three hundred and fourteen CLD patients who underwent gadobenate dimeglumine-enhanced hepatic magnetic resonance imaging were stratified into three groups: nonadvanced CLD (n = 116), compensated advanced CLD (n = 120), and decompensated advanced CLD (n = 78) groups. The liver-to-portal vein contrast ratio (LPC) and liver-spleen contrast ratio (LSC) at the hepatobiliary phase were measured. The value of LPC for predicting hepatic decompensation and transplant-free survival was assessed using Cox regression analysis and Kaplan-Meier analysis. RESULTS The diagnostic performance of LPC was significantly better than LSC in evaluating the severity of CLD. During a median follow-up period of 53.0 months, the LPC was a significant predictor for hepatic decompensation (p < 0.001) in patients with compensated advanced CLD. The predictive performance of LPC was higher than that of the model for end-stage liver disease score (p = 0.006). With the optimal cut-off value, patients with LPC ≤ 0.98 had a higher cumulative incidence of hepatic decompensation than patients with LPC > 0.98 (p < 0.001). The LPC was also a significant predictive factor for transplant-free survival in patients with compensated advanced CLD (p = 0.007) and those with decompensated advanced CLD (p = 0.002). CONCLUSIONS Contrast-enhanced portal vein imaging at the hepatobiliary phase obtained with gadobenate dimeglumine is a valuable imaging biomarker for predicting hepatic decompensation and transplant-free survival in CLD patients. KEY POINTS • The liver-to-portal vein contrast ratio (LPC) significantly outperformed liver-spleen contrast ratio in evaluating the severity of chronic liver disease. • The LPC was a significant predictor for hepatic decompensation in patients with compensated advanced chronic liver disease. • The LPC was a significant predictor for transplant-free survival in patients with compensated and those with decompensated advanced chronic liver disease.

Abstract
Background/Aim To evaluate the applicability of transarterial chemoembolization (TACE) treatment with doxorubicin drug-eluting beads (DEBs) in advanced hepatocellular carcinoma (HCC) patients with portal vein invasion (PVI). Methods This prospective study was approved by the institutional review board and informed consent was obtained from all participants. A total of 30 HCC patients with PVI received DEB-TACE between 2015 and 2018. The following parameters were evaluated: complications during DEB-TACE, abdominal pain, fever, and laboratory outcomes, including liver function change. Overall survival (OS), time to progression (TTP), and adverse events were also analyzed and assessed. Results DEBs measuring 100-300 μm in diameter were loaded with doxorubicin (150 mg per procedure). There were no complications during DEB-TACE and no significant differences in the levels of prothrombin time, serum albumin, or total bilirubin at follow-up compared to baseline. The median TTP was 102 days (95% confidence interval [CI], 42-207 days) and the median OS was 216 days (95% CI, 160-336 days). Three patients (10%) had severe adverse reactions, including transient acute cholangitis (n=1), cerebellar infarction (n=1), and pulmonary embolism (n=1), but no treatment-related death occurred. Conclusions DEB-TACE may be a therapeutic option for advanced HCC patients with PVI.

Abstract
COVID-19 infection has been associated, particularly in severely ill patients requiring hospitalization, with a hypercoagulable state. The case presented herein was a 66-year-old man with SARS-CoV-2 infection who did not have any respiratory symptoms. He presented with the following clinical manifestations: portal vein and hepatic artery thrombosis, liver infarction, and a superimposed abscess of the liver. In this case, early detection and the administration of anticoagulants and antibiotics led to a significant improvement within weeks of the diagnosis. We encourage physicians to be aware of COVID-19-associated hypercoagulable state and its potential complications, regardless of the acuity of the presentation or the absence of respiratory symptoms.

Abstract
Portal vein aneurysm (PVA) is a rare vascular abnormality, representing 3% of all venous aneurysms in the human body, and is not well understood. It can be congenital or acquired, located mainly at the level of confluence, main trunk, branches and bifurcation. A PVA as an abnormality of the portal venous system was first reported in 1956 by Barzilai and Kleckner. A review from 2015 entitled “Portal vein aneurysm: What to know” considered fewer than 200 cases. In the last seven years, there has been an increase in the number of PVAs diagnosed thanks to routine abdominal imaging. The aim of this review is to provide a comprehensive update of PVA, including aetiology, epidemiology, and clinical assessment, along with an evaluation of advanced multimodal imaging features of aneurysm and management approaches.

Abstract
OBJECTIVE To develop a novel logistic regression model based on liver/spleen volumes and portal vein diameter measured on magnetic resonance imaging (MRI) for predicting oesophagogastric variceal bleeding (OVB) secondary to HBV cirrhosis. METHODS One hundred eighty-five consecutive cirrhotic patients with hepatitis B undergoing abdominal contrast-enhanced MRI were randomly divided into training cohort (n = 130) and validation cohort (n = 55). Spleen volume, total liver volume, four liver lobe volumes, and diameters of portal venous system were measured on MRI. Ratios of spleen volume to total liver and to individual liver lobe volumes were calculated. In training cohort, univariate analyses and binary logistic regression analyses were to determine independent predictors. Performance of the model for predicting OVB constructed based on independent predictors from training cohort was evaluated by receiver operating characteristic (ROC) analysis, and was validated by Kappa test in validation cohort. RESULTS OVB occurred in 42 and 18 individuals in training and validation cohorts during the 2 years' follow-up, respectively. An OVB prediction model was constructed based on the independent predictors including right liver lobe volume (RV), left gastric vein diameter (LGVD) and portal vein diameter (PVD) (odds ratio = 0.993, 2.202 and 1.613, respectively; p-values < 0.001 for all). The logistic regression model equation (-0.007 × RV + 0.79 × LGVD + 0.478 × PVD-6.73) for predicting OVB obtained excellent performance with an area under ROC curve of 0.907. The excellent performance was confirmed by Kappa test with K-value of 0.802 in validation cohort. CONCLUSION The novel logistic regression model can be reliable for predicting OVB. KEY POINTS • Patients with oesophagogastric variceal bleeding are mainly characterized by decreased right lobe volume, and increased spleen volume and diameters of portal vein system. • The right liver lobe volume, left gastric vein diameter and portal vein diameter are the independent predictors of oesophagogastric variceal bleeding. • The novel model developed based on the independent predictors performed well in predicting oesophagogastric variceal bleeding with an area under the receiver operating characteristic curve of 0.907.

Abstract
BACKGROUND Portal vein tumor thrombosis (PVTT) secondary to primary liver carcinoma (PLC) is commonly associated with poor prognosis and poses great challenge. This study was to evaluate the efficacy and safety of percutaneous endovascular radiofrequency ablation (RFA) in treatment of PVTT. METHODS Consecutive patients who were performed endovascular RFA because of PVTT in single-institution in recent 8 years were retrospectively reviewed, compared with patients who underwent only sequential transcatheter arterial chemoembolization (TACE) during the contemporary period. Patency of portal vein, complications, and overall survival (OS) were investigated. RESULTS One hundred and 20 patients who underwent endovascular RFA and 96 patients who underwent only sequential TACE were included. No severe complications happened in both groups. Except the higher rates of severe fever and moderate pain in the study group, no difference was found in the incidence of side effects and complications. The effective rate in the study group was (78.3%, 94/120) significantly higher than the comparison group (35.4%, 34/96). The median survival time and 1-3 years cumulative survival rates in the study group were 15.7 months and 42.5%, 21.7%, 2.5%, respectively, and 11.3 months, 21.9%, 9.4%, 0 correspondingly in the comparison group, without significant difference. Type of PVTT and Child-Pugh classification of liver function were independent risk factors, and OS was significantly improved by endovascular RFA and subsequent therapy. CONCLUSION Endovascular RFA is technically safe and feasible for unresectable PLC and PVTT to improve the prognosis and quality of life.

Abstract
The portal vein is the largest vessel supplying the liver. A number of radiological interventions are performed through the portal vein, namely for primary pathologies of the portal vein, for inducing liver hypertrophy or to treat the sequelae of portal hypertension among others. The routes used include direct transhepatic, transjugular, and, uncommonly, trans-splenic and through subcutaneous varices. Portal vein embolization and transjugular intrahepatic portosystemic shunt are among the most common portal vein interventions that are performed to induce hypertrophy of the future liver remnant and to treat complications of portal hypertension, respectively. Other interventions include transhepatic obliteration of varices and shunts, portal vein thrombolysis, portal vein recanalization, pancreatic islet cell transplantation, and embolization of portal vein injuries. We present a detailed illustrative review of the various radiological portal vein interventions.

Abstract
Congenital intrahepatic portosystemic venous shunt (CPSVS), a rare vascular malformation, has been described in both children and adults and can lead to severe neurophysiological complications. However, a standard therapeutic protocol for CPSVS has not been elucidated. With the advantage of minimally invasive techniques, transcatheter embolization has been used to treat CPSVS. The condition is challenging to manage, especially in patients with large or multiple shunts, through which rapid blood flow can cause ectopic embolism. Here, we describe a case of CPSVS with a large shunt that was successfully treated with balloon-occluded retrograde transvenous obliteration with interlocking detachable coils.

Abstract
The liver has a complex vascular anatomy with a unique dual blood supply. Clinical conditions of the liver vary widely and include disorders originating in the vascular and biliary systems as well as the parenchyma. In most vascular disorders, the effects on the liver are generally subclinical because of its abundant blood supply. However, early diagnosis of such vascular diseases can significantly reduce patient morbidity and mortality. Because imaging findings of vascular disease are not always readily apparent, diagnosis can be difficult. Computed tomography angiography is an excellent imaging modality for visualizing the vascular anatomy of patients for treatment planning. In this review article, we focus on the vascular anatomy of the liver and the imaging findings in some acute hepatic vascular diseases.

Abstract
PURPOSE Completely occlusive acute-subacute portal and mesenteric vein thrombosis (PVMVT) with severe complications is fatal. Endovascular treatments (EVTs) of acute-subacute PVMVT are not standardized. Thrombectomy combined with continuous catheter-directed thrombolysis is considered an effective treatment. Here, we aimed to evaluate the outcome of EVTs of completely occlusive acute-subacute PVMVT with severe complications in patients without cirrhosis. MATERIALS AND METHODS Nineteen patients (nine men and 10 women; age, 60.1 ± 16.8 years) with completely occlusive acute-subacute PVMVT were retrospectively assessed. Acute-subacute PVMVT was defined as symptom onset within 40 days, with no cavernous transformation observed on contrast-enhanced computed tomography. The patients were treated with EVTs, a combination of thrombectomy (including aspiration thrombectomy, plain old balloon angioplasty, single injection of thrombolytic agents, and stent placement) and continuous catheter-directed thrombolysis. Kaplan-Meier analyses were performed to assess all-cause mortality, acute-subacute PVMVT-related mortality, and portal vein (PV) patency. The degree of recanalization and patency of PV, complications, factors related to acute-subacute PVMVT-related mortality, and factors related to patency of PV were also evaluated. RESULTS The all-cause and acute-subacute PVMVT-related mortality rates were 36.8% (7/19) and 31.6% (6/19), respectively. Seven (36.8%) and 11 (57.9%) patients achieved complete and partial recanalization, respectively. Among the 18 patients who achieved recanalization, follow-up images after 608.7 ± 889.5 days confirmed recanalization in 83.3% (15/18) patients, and 53.3% (8/15) of these patients achieved patency of PV. Seven patients (36.8%) developed complications, and two (10.5%) required interventional treatment for complications. Deterioration of liver function significantly worsened the prognosis (P = 0.046), while anticoagulation therapy significantly maintained portal patency (P = 0.03). CONCLUSION This endovascular method for acute-subacute PVMVT, which combines thrombectomy and continuous catheter-directed thrombolysis EVT approach was effective for thrombus resolution. However, further studies must define conditions that improve patient prognosis.

Abstract
Coronavirus disease 2019 (COVID-19) and COVID-19 vaccination may cause splanchnic vein thrombosis (SVT), which is potentially fatal. The present study aims to pool the incidence and outcomes of SVT patients with COVID-19 or having received COVID-19 vaccines. The PubMed, EMBASE, and Cochrane databases were searched. Based on the data from cohort studies, meta-analyses were performed to evaluate the incidence of SVT in COVID-19 patients or people having received COVID-19 vaccines. Pooled proportions were calculated. Based on the individual data from case reports, logistic regression analyses were performed to identify factors associated with death in SVT patients. Odds ratios (ORs) were calculated. Among 654 papers initially identified, 135 were included. Based on 12 cohort studies, the pooled incidence of SVT in COVID-19 patients was 0.6%. Data were insufficient to estimate the incidence of SVT after COVID-19 vaccination. Based on 123 case reports, the mortality was 14% (9/64) in SVT patients with COVID-19 and 25% (15/59) in those who received COVID-19 vaccines. Univariate analyses demonstrated that age (OR = 1.061; p = 0.017), diabetes mellitus (OR = 14.00; p = 0.002), anticoagulation (OR = 0.098; p = 0.004), and bowel resection (OR = 16.00; p = 0.001) were significantly associated with death in SVT patients with COVID-19; and anticoagulation (OR = 0.025; p = 0.003) and intravenous immunoglobulin (OR = 0.175; p = 0.046) were significantly associated with death in SVT patients who received COVID-19 vaccines. Multivariate analyses did not identify any independent factor for death in both patients. SVT in COVID-19 patients and in subjects who received COVID-19 vaccines carries a high mortality, but may be improved by anticoagulation. PROSPERO Identifier CRD42022315254.

Abstract
OBJECTIVE Organ transplantation is the last therapeutic choice for end-stage liver failure, which is limited by the lack of sufficient donors. Decellularized liver can be used as a suitable matrix for liver tissue engineering with clinical application potential. Optimizing the decellularization procedure would obtain a biological matrix with completely removed cellular components and preserved 3-dimensional structure. This study aimed to evaluate the decellularization efficacy through three anatomical routes. MATERIALS AND METHODS In this experimental study, rat liver decellularization was performed through biliary duct (BD), portal vein (PV), and hepatic vein (HV); using chemical detergents and enzymes. The decellularization efficacy was evaluated by measurement of DNA content, extracellular matrix (ECM) total proteins, and glycosaminoglycans (GAGs). ECM preservation was examined by histological and immunohistochemical (IHC) staining and scanning electron microscopy (SEM). Scaffold biocompatibility was tested by the MTT assay for HepG2 and HUVEC cell lines. RESULTS Decellularization through HV and PV resulted in a transparent scaffold by complete cell removal, while the BD route produced an opaque scaffold with incomplete decellularization. H and E staining confirmed these results. Maximum DNA loss was obtained using 1% and 0.5% sodium dodecyl sulfate (SDS) in the PV and HV groups and the DNA content decreased faster in the HV group. At the final stages, the proteins excreted in the HV and PV groups were significantly less than the BD group. The GAGs level was diminished after decellularization, especially in the PV and HV groups. In the HV and PV groups the collagen amount was significantly more than the BD group. The IHC and SEM images showed that the ECM structure was preserved and cellular components were entirely removed. MTT assay showed the biocompatibility of the decellularized scaffold. CONCLUSION The results revealed that the HV is a more suitable route for liver decellularization than the PV and BD.

Abstract
PURPOSE Portal vein thrombus (PVT) can worsen portal hypertension and hepatic decompensation in patients with cirrhosis and impact liver transplant outcomes. This retrospective case series describes large bore mechanical thrombectomy of PVT with the Inari FlowTriever device during, or remotely after, transjugular intrahepatic portosystemic shunt (TIPS) placement. MATERIALS AND METHODS Ten patients with PVT were treated with large bore thrombectomy. All patients had underlying cirrhosis, complicated by portal hypertension with acute/subacute PVT. Thrombectomy was performed either with TIPS placement, or via a previously placed thrombosed shunt. Median time from TIPS placement to thrombectomy was 3 years. RESULTS Thrombectomy was technically successful in all patients with a majority achieving complete resolution of PVT in a single session. During mean follow-up of 13.3 months, all patients achieved complete resolution of PVT without recurrence. CONCLUSION Large bore mechanical thrombectomy together with TIPS is a feasible and effective treatment of acute/subacute PVT in cirrhotic patients with portal hypertension, often with complete resolution in a single session.

Abstract
PURPOSE The aim of this study was to explore the improved image quality of the portal vein using the contrast-enhancement boost (CE-boost) technique for the improved visibility of abdominal-enhanced computed tomography (CT) scans in clinical practice. METHODS This retrospective study included 50 patients in Group A who underwent routine abdominal-enhanced CT and 50 patients in Group B who underwent abdominal computed tomography angiography (CTA) with matched body mass index, age, and sex. Images in Group A were postprocessed with the CE-boost technique for further enhanced visibility of the portal vein. Both subjective and objective assessments of different branches of the portal vein in three types of images (i.e., Group A with CE-boost and without CE-boost, Group B) were statistically analyzed. RESULTS The subjective scores of two experienced radiologists showed good consistency (kappa value > 0.624, p < 0.001), and the score of Group A with CE-boost (mean, 4.64) was significantly higher than that of the others (p < 0.001). The liver parenchyma and most target veins in Group A with CE-boost showed the highest CT, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) values and the lowest standard deviation (SD), while the CNR of most portal veins in Group A without CE-boost had the lowest CNR (p < 0.001). There were no differences in the SNR of the portal vein in Group A without CE-Boost and Group B (p > 0.05). CONCLUSION CE-boost can significantly improve image quality in portal vein imaging without any additional scanning settings or changes in the clinical workflow.

Abstract
OBJECTIVES Porto-sinusoidal vascular disorder (PSVD) is a recently defined vascular liver disease. Since diagnosis remains challenging, we aimed to evaluate radiological features that are distinct between PSVD and cirrhosis. METHODS Clinical, laboratory, and radiological parameters (CT/MRI) of patients with histologically-confirmed PSVD vs. cirrhosis vs. non-cirrhotic parenchymal liver disease were retrospectively evaluated. RESULTS Sixty-three PSVD, 155 cirrhosis, and 41 non-cirrhotic patients were included. As compared to cirrhosis, PSVD patients were younger and had lower HVPG, liver stiffness, and MELD. Routine clinical and imaging findings indicative of portal hypertension were similarly common. Intrahepatic portal tract abnormalities (49% vs. 15%; p < 0.001), FNH-like lesions (30% vs. 1%; p < 0.001), and abnormal liver morphology defined as peripheral parenchymal atrophy and compensatory hypertrophy of central segments (32% vs. 7%; p < 0.001) were significantly more common in PSVD patients. Hypertrophy of segment I (70% vs. 84%; p = 0.019), atrophy of segment IV (24% vs. 47%; p = 0.001), and nodular liver surface (22% vs. 89%; p < 0.001) were more common in patients with cirrhosis. In patients with gadoxetic acid-enhanced MRI, we identified the distinct imaging feature of "periportal hyperintensity" in the hepatobiliary phase (HBP) in 42% of patients with PSVD (14/33) vs. 1% in cirrhosis (1/95) vs. 0% in non-cirrhotic controls (0/41); p < 0.001). CONCLUSIONS Diagnosis of PSVD must be considered in younger patients presenting with clinical features of portal hypertension, portal tract abnormalities, and FNH-like lesions on CT/MRI. 'Periportal hyperintensity' in the HBP of gadoxetic acid-enhanced MRI was identified as a specific radiological feature of PSVD. KEY POINTS • Cross-sectional imaging can provide essential information to identify patients with porto-sinusoidal vascular disorder (PSVD). • Intrahepatic portal tract abnormalities, FNH-like lesions, and abnormal liver morphology are common in PSVD patients. • Periportal hyperintensity on the hepatobiliary phase of gadoxetic acid-enhanced MRI seems to be specific for patients with PSVD.

Abstract
Portal vein anatomic variations are common in living donor liver transplantation. Portal vein fenestration, in which a segment of a vessel divides into at least two channels that reunite into a single distal lumen, has not yet been reported in the literature. Failure to identify this anomaly can lead to catastrophic events in donor liver hepatectomy. Herein, we report an unusual portal vein anomaly that was detected intraoperatively in a living liver donor.

Abstract
PURPOSE Vascular resection (VR) is extended surgery to attain a negative radial margin (RM) for distal cholangiocarcinoma (DCC). The present study explored the significance of VR for DCC, focusing on VR, RM, and findings suggestive of vascular invasion on multidetector-row computed tomography (MDCT). METHODS Patients with DCC who underwent resection between 2002 and 2019 were reviewed. RESULTS Among 230 patients, 25 received VR. The overall survival (OS) in the VR group was significantly worse than in the non-VR group (16.7% vs. 50.7% at 5 years, P < 0.001). Patients who underwent VR with a negative RM failed to show a better OS than those who did not undergo VR with a positive RM (19.7% vs. 35.7% at 5 years, P = 0.178). Of the 30 patients who were suspected of having vascular invasion on MDCT, 11 did not receive VR because the vessels were freed from the tumor; these patients had a significantly better OS (57.9% at 5 years) than those who underwent VR. CONCLUSIONS VR for DCC was associated with a poor prognosis, even if a negative RM was obtained. VR is not necessary for DCC when the vessels are detachable from the tumor.

Abstract
Background/aim Portal vein system thrombosis (PVST) is a serious complication after splenectomy, and many researches focus on how to prevent PVST these years. The current study aimed to explore an effectively method to prevent PVST occur after splenectomy. Methods Records of patients performed with splenectomy from January 2018 to December 2020 were reviewed. Clinical parameters, including patient history, physical examination, and the results of laboratory investigations, were analyzed. Results One hundred and eighty patients (127 females) were included. Twenty-four patients were confirmed PVST by Color Doppler ultrasonography and CTA (thrombus group) and the others were not (non-thrombus group). One hundred and twenty patients were performed with laparoscopic splenectomy (LS) and 53 were open splenectomy (OS). Seventeen PVST were found in LS patients and 7 PVST were found in OS patients (P = 0.974). The average time of thrombosis was 4.48 ± 2.9 days after operation. The proportion of postoperative preventive use of low molecular weight heparin (LMWH) in non-thrombus group was higher than that in thrombus group (27.6% vs. 8.3%, P = 0.045). Compared with the non-thrombus group, the thrombus group showed significantly higher serum alanine transaminase (ALT) and aspartate transaminase (AST) 7 days after splenectomy (79.67 ± 39.1 U/L vs. 29.34 ± 2.5 U/L, P = 0.001; 192.4 ± 145.8 U/L vs. 30.54 ± 3.0 U/L, P < 0.001). Conclusion Laparoscopic splenectomy does not seem to increase the occurrence of PVST in patients without portal hypertension. Early postoperative preventive use of LMWH after splenectomy may prevent the formation of PVST.

Abstract
Backgrounds/Aims Although body surface area (BSA)-based standard liver volume (SLV) formulae have been used for living donor liver transplantation and hepatic resection, hemi-liver volume (HLV) is needed more frequently. HLV can be assessed using right or left portal vein diameter (RPVD or LPVD). The aim of this study was to validate the reliability of using portal vein diameter ratio (PVDR) for assessing HLV in living liver donors. Methods This study included 92 living liver donors (59 males and 33 females) who underwent surgery between January 2020 and December 2020. Computed tomography (CT) images were used for measurements. Results Mean age of donors was 35.5 ± 7.2 years. CT volumetry-measured total liver volume (TLV), right HLV, left HLV, and percentage of right HLV in TLV were 1,442.9 ± 314.2 mL, 931.5 ± 206.4 mL, 551.4 ± 126.5 mL, and 64.6% ± 3.6%, respectively. RPVD, LPVD, and main portal vein diameter were 12.2 ± 1.5 mm, 10.0 ± 1.3 mm, and 15.3 ± 1.7 mm, respectively (corresponding square values: 149.9 ± 36.9 mm2, 101.5 ± 25.2 mm2, and 237.2 ± 52.2 mm2, respectively). The sum of RPVD2 and LPVD2 was 251.1 ± 56.9 mm2. BSA-based SLV was 1,279.5 ± 188.7 mL (error rate: 9.1% ± 14.4%). SLV formula- and PVDR-based right HLV was 760.0 ± 130.7 mL (error rate: 16.2% ± 13.3%). Conclusions Combining BSA-based SLV and PVDR appears to be a simple method to predict right or left HLV in living donors or split liver transplantation.
