Abstract
Interventions for portal hypertension are continuously evolving and expanding beyond the realm of medical management. When complications such as varices and ascites persist despite conservative interventions, procedures including transjugular intrahepatic portosystemic shunt creation, transvenous obliteration, portal vein recanalization, splenic artery embolization, surgical shunt creation, and devascularization are all potential interventions detailed in this article. Selection of the optimal procedure to address the underlying cause, treat symptoms, and, in some cases, bridge to liver transplantation depends on the specific etiology of portal hypertension and the patient's comorbidities.

Abstract
Patients with cirrhosis develop complex alterations in primary hemostasis that include both hypocoagulable and hypercoagulable features. This includes thrombocytopenia, multiple alterations of platelet function, and increased plasma levels of von Willebrand factor. Contrary to the historical view that platelet dysfunction in cirrhosis might be responsible for an increased bleeding tendency, the current theory posits a rebalanced hemostasis in patients with cirrhosis. Severe thrombocytopenia is not indicative of the bleeding risk in patients undergoing invasive procedures and does not dictate per se the need for pre-procedural prophylaxis. A more comprehensive and individualized risk assessment should combine hemostatic impairment, the severity of decompensation and systemic inflammation, and the presence of additional factors that may impair platelet function, such as acute kidney injury and bacterial infections. Although there are multiple, complex alterations of platelet function in cirrhosis, their net effect is not yet fully understood. More investigations evaluating the association between alterations of platelet function and bleeding/thrombosis may improve risk stratification in patients with decompensated cirrhosis. Besides hemostasis, the assessment of von Willebrand factor Ag and ADP-induced, whole-blood platelet aggregation normalized by platelet count (VITRO score and PLT ratio) are promising biomarkers to predict the risk of hepatic decompensation and survival in both compensated and decompensated patients. Further investigations into the in vivo interplay between platelets, circulating blood elements, and endothelial cells may help advance our understanding of cirrhotic coagulopathy. Here, we review the complex changes in platelets and primary hemostasis in cirrhosis and their potential clinical implications.

Abstract
Ectopic variceal bleeding is a rare cause of gastrointestinal bleeding that can occur in settings of cirrhotic and non-cirrhotic portal hypertension and is characterised by its development at locations remote from the oesophagus and stomach. Ectopic varices can be difficult to identify and access, and, although a relatively uncommon cause of portal hypertensive bleeding, can represent a difficult diagnostic and therapeutic challenge associated with considerable mortality. Low incidence and variance in variceal anatomy preclude large randomised controlled trials, and clinical practice is based on experience from case reports, case series, and specialist centre expertise. Optimisation of survival outcomes relies on understanding a patient's portal venous anatomy and functional hepatic reserve to guide timely and targeted endoscopic and endovascular interventions to facilitate the rapid control of ectopic variceal bleeding.

Abstract
Cirrhosis is a complex diffuse process whereby the architecture of the liver is replaced by abnormal nodules because of the presence of fibrosis. Several pediatric diseases such as extrahepatic portal vein obstruction, biliary atresia, alpha-1-antitrypsin deficit and autoimmune hepatitis can lead to cirrhosis and portal hypertension in children. In this article the authors describe interventional radiology procedures that can facilitate the diagnosis and treatment of diseases associated with liver cirrhosis and portal hypertension in the pediatric population. These procedures include image-guided liver biopsy, mesenteric-intrahepatic left portal vein shunts, balloon-occluded retrograde transvenous obliteration, transjugular intrahepatic portosystemic shunts and splenic embolization.

Abstract
Background and Aim Balloon‐occluded retrograde transvenous obliteration (BRTO) has been widely adopted for the management of gastric fundal varices (GVs). There are a few reports that BRTO leads to the improvement of mid‐term and long‐term hepatic functional reserve (HFR). We retrospectively investigated the long‐term effect on HFR and prognosis among patients who had undergone BRTO for GVs. Methods This single‐center, retrospective study included 57successful patients out of 60 patients who underwent BRTO for GVs from December 2005 to September 2018. We examined the indicators of HFR (e.g., encephalopathy and ascites statuses, serum total bilirubin and albumin levels, % prothrombin time, and Child–Pugh and albumin–bilirubin [ALBI] scores) during 3 years of follow‐up after BRTO. We analyzed survival using the Kaplan–Meier method and identified the independent prognostic factors via multivariate analyses. Results GVs disappeared in all patients who were successfully treated by BRTO. At 3 years after BRTO, serum albumin levels were significantly elevated (from 3.3 to 4.0 g/dL, P = 0.008), while Child–Pugh and ALBI scores were significantly decreased (from 7.0 to 5.7, P = 0.043, and from −1.94 to −2.60, P = 0.006, respectively). The median survival time among all patients was 2207 days; the survival rates after BRTO were 87.0% at 1 year, 81.8% at 3 years, 67.3% at 5 years, and 44.1% at 10 years. Multivariate analyses revealed that ascites, hepatic encephalopathy, and malignant neoplasms were independently associated with poor prognosis. Conclusion BRTO for GVs has a favorable effect on long‐term HFR.

[PMID: 34706678 PMCID: PMC8555096 DOI: 10.1186/s12876-021-01991-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 10/25/2021] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND To investigate the safety and efficacy of 8Spheres in partial splenic embolization. To explore the possibility of accurate control of splenic embolic volume by quantifying the number of microspheres used during PSE. METHOD The data of 179 patients who underwent PSE were collected. The patients were divided into two groups: 300-500 um microsphere group (N = 83) and 500-700 um microsphere group (N = 96). The spleen volume before PSE, infarct volume and infarct rate of the spleen after PSE, changes in peripheral blood cells after PSE, postoperative adverse events and incidence of infection were compared between the two groups. RESULTS 300-500 um group vs 500-700 um group: postoperative spleen volume (cm3): 753.82 ± 325.41 vs 568.65 ± 298.16 (P = 0.008); spleen embolization volume (cm3): 525.93 ± 118.29 vs 630.26 ± 109.71 (P = 0.014); spleen embolization rate: 41.1 ± 12.3% vs 52.4 ± 10.1% (P = 0.021). Leukocytes and platelets were significantly increased after PSE in both groups; leukocyte, 1 month: 4.13 ± 0.91 vs 5.08 ± 1.16 (P = 0.026); 3 months: 4.08 ± 1.25 vs 4.83 ± 0.98 (P = 0.022); platelet, 1 month: 125.6 ± 20.3 vs 138.7 ± 18.4 (P = 0.019); 3 months: 121.8 ± 16.9 vs 134.3 ± 20.1 (P = 0.017). Incidence of abdominal pain after PSE, 72 (86.7%) vs 69 (71.9%), P = 0.027. The incidence of other adverse events and infections after PSE was not statistically different. CONCLUSION PSE with 8Spheres is safe and effective. The use of 500-700 um microsphere for PSE can make the increase of peripheral blood cells more stable. Each vial of 8Spheres corresponds to a certain volume of splenic embolization, so it is possible to achieve quantitative embolization in PSE.

Abstract
Abstract
Objectives Sinistral portal hypertension (SPH) is caused by increased pressure on the left portal system secondary to splenic vein stenosis or occlusion and may lead to gastric varices. The definitive management of SPH is splenectomy, but this is associated with significant mortality and morbidity in the acute setting. In this systematic review, we investigated the efficacy and safety of splenic artery embolisation (SAE) in managing refractory variceal bleeding in patients with SPH.
Methods A comprehensive literature search was conducted using MEDLINE and Embase databases. A qualitative analysis was chosen due to heterogeneity of the studies.
Results Our search yielded 339 articles, 278 of which were unique. After initial screening, 16 articles relevant to our search remained for full text review. Of these, 7 were included in the systematic review. All 7 papers were observational, 6 were retrospective. Between them they described 29 SAE procedures to control variceal bleeding. The technical success rate was 100% and there were no cases of rebleeding during follow up. The most common complication was post-embolisation syndrome. Four major complications occurred, two resulting in death. These deaths were the only 30-day mortalities recorded and were in patients with extensive comorbidities.
Conclusions Although there is a distinct lack of randomized controlled studies comparing SAE to other treatment modalities, it appears to be safe and effective in treating hemorrhage secondary to SPH.

Abstract
Purpose To compare effectiveness of three widely used embolic agents in partial splenic embolization (PSE) by analyzing their clinical, laboratory, and radiological outcomes within one year of follow-up. Materials and methods This retrospective study examined 179 patients who underwent PSE to manage hypersplenism secondary to cirrhosis. Patients were divided into 3 groups according to embolic agent used. Group 1 (gelatin sponge) included 65 patients, group 2 (embospheres) included 58 patients, and group 3 (PVA) included 56 patients. Clinical, laboratory, and radiological outcomes were compared between groups. Results The technical success rate was 100% in all groups. Pain as a major complication was lower in the gelatin sponge group (20%) compared to the embosphere group (31%) and PVA group (32.3%). Major complications other than pain were found in 20.1%; 24.6% in gelatin sponge group, 15.5% in embosphere group and 19.6% in PVA group (p = 0.045). WBCs and platelet counts showed a significant increase after PSE in all groups. Entire splenic volume as measured by computed tomography after PSE showed no significant difference among the 3 groups; however, the volume of infarcted spleen was significantly lower in the gelatin sponge group compared to other two groups (p = 0.001). The splenic span was significantly reduced one-year post-procedure in three groups (p = 0.006), and it was significantly less in embosphere and PVA groups compared to gelatin sponge group (p < 0.05). Recurrent bleeding was higher in gelatin sponge group (p < 0.05). Conclusions Permanent embolic materials achieved better laboratory and radiological outcomes than gelatin sponge particles in PSE of cirrhotic hypersplenism patients. However, permanent particles were associated with greater abdominal pain.

Abstract
Portal hypertension is a clinical syndrome characterized by an increase in the portal pressure gradient, defined as the gradient between the portal vein at the site downstream of the site of obstruction and the inferior vena cava. The most frequent cause of portal hypertension is cirrhosis. In patients with cirrhosis, portal hypertension is the main driver of cirrhosis progression and development of hepatic decompensation (ascites, variceal hemorrhage and hepatic encephalopathy), which defines the transition from compensated to decompensated stage. In decompensated patients, treatments aim at lowering the risk of death by preventing further decompensation and/or development of acute-on-chronic liver failure. Decompensated patients often pose a complex challenge which typically requires a multidisciplinary approach. The aims of the present review were to discuss the current knowledge regarding interventional treatments for patients with portal hypertension complications as well as to highlight useful information to aid hepatologists in their clinical practice. Specifically, we discussed the indications and contraindications of transjugular intra-hepatic portosystemic shunt and for the treatment of gastro-esophageal variceal hemorrhage in patients with decompensated cirrhosis (first section); we reviewed the use of interventional treatments in patients with hepatic vein obstruction (Budd-Chiari Syndrome) and in those with portal vein thrombosis (second section); and we briefly comment on the most frequent applications of selective splenic embolization in patients with and without underlying cirrhosis (third section).

Abstract
Primary liver cancer often occurs in patients with hepatitis and cirrhosis. Some patients have portal hypertension due to cirrhosis, and present with varying degrees of collateral circulation, splenomegaly and hypersplenism, ascites, and liver dysfunction. It often interferes with the treatment of tumors and affects the disease prognosis. There are internationally recognized guidelines for interventional treatment of liver cancer and portal hypertension which will not be repeated in this paper. This paper focuses on how to treat portal hypertension and intervene with tumors in the treatment of liver cancer to optimize the management of patients with liver cancer and portal hypertension. We propose that the Interventional Management Mode of Liver Cancer with Portal Hypertension can improve the treatment of liver cancer patients with portal hypertension.

Abstract
Introduction Upper gastrointestinal bleeding (UGIB) is a severe and life-threatening complication among patients with portal hypertension (PH). Covered transjugular intrahepatic portosystemic shunt (TIPS) is the treatment of choice for patients with refractory or recurrent UGIB despite pharmacological and endoscopic therapy. In some patients, TIPS implantation is not possible due to co-morbidity or vascular disorders. Spleen embolization (SE) may be a promising alternative in this setting. Materials and methods We retrospectively analyzed 9 patients with PH-induced UGIB who underwent partial SE between 2012 and 2016. All patients met the following criteria: (i) upper gastrointestinal hemorrhage with primary or secondary failure of endoscopic interventions and (ii) TIPS implantation not possible. Each patient was followed for at least 6 months after embolization. Results Five patients (56%) suffered from cirrhotic PH, 4 patients (44%) from non-cirrhotic PH. UGIB occured in terms of refractory hemorrhage from gastric varices (3/9; 33%), hemorrhage from esophageal varices (3/9; 33%), and finally, hemorrhage from portal-hypertensive gastropathy (3/9; 33%). None of the patients treated with partial SE experienced re-bleeding episodes or required blood transfusions during a total follow-up time of 159 months, including both patients with cirrhotic- and non-cirrhotic PH. Discussion Partial SE, as a minimally invasive intervention with low procedure-associated complications, may be a valuable alternative for patients with recurrent PH-induced UGIB refractory to standard therapy.

Abstract
BACKGROUND/AIMS Partial splenic embolization (PSE) is used in the management of gastroesophageal variceal hemorrhage (GEVH). However, it is uncertain whether it has beneficial effects for GEVH patients in preventing variceal recurrence and variceal hemorrhage, as well as promoting overall survival (OS), when it is combined with conventional therapies. MATERIALS AND METHODS The databases including PubMed, EMBASE, Web of Science, Google scholar, and Cochrane Central Register of Controlled Trials were searched up to 11th of November, 2015. Meta-analyses were performed by using Review Manager 5.3 software for analyzing the risk of bias, Newcastle-Ottawa Scale for assessing the bias of cohort studies, and GRADEprofiler software for assessing outcomes obtained from the meta-analyses. RESULTS A total of 1505 articles were reviewed, and 1 randomized controlled trial and 5 cohort studies with 244 participants were eligible for inclusion. The pooled hazard ratio (HR) of variceal recurrence is 0.50 (95% confidence interval (CI) 0.37, 0.68; P< 0.00001; I2 = 0%). The pooled HR of variceal hemorrhage is 0.24 (95% CI 0.15, 0.39; P< 0.00001; I2 = 0%). The pooled HR of OS is 0.50 (95% CI 0.33, 0.67; P< 0.00001; I2 = 0%). Meta-analyses demonstrated statistically significant superiority of combinational therapies over conventional therapies in preventing variceal recurrence and variceal hemorrhage and prolonging OS. The complications related to PSE were mild or moderate and nonfatal. CONCLUSIONS The results indicate that PSE has beneficial effects for GEVH patients, however, future investigation with a larger number of subjects in clinical trials is warranted.

Abstract
BACKGROUND Partial splenic artery embolization (PSE) is an effective treatment modality for patients with hypersplenism. It is less invasive and has a quicker recovery compared with surgical procedures. PSE is usually performed using a femoral artery approach that requires bedrest for a few hours, which is rarely the case for transradial PSE. PURPOSE To compare the transradial and transfemoral approaches for embolization of spleen in patients with hypersplenism. MATERIAL AND METHODS In all, 84 patients with hypersplenism who required PSE were recruited. They were randomly divided into two groups on the basis of the procedure followed: the transradial approach (R-PSE, n = 39) or transfemoral approach (F-PSE, n = 45). Technical success, puncture rate, total procedure time, X-ray exposure time, length of stay in hospital (LOS), and complications of the two groups were recorded. RESULTS The procedure time, X-ray exposure time, and LOS were found to be lower in the R-PSE group than in the F-PSE. However, this difference was not statistically significant. CONCLUSION The transradial artery approach for PSE in patients with hypersplenism is feasible with no major complications as compared to the femoral approach.

Abstract
The Japanese Society of Gastroenterology revised the evidence-based clinical practice guidelines for liver cirrhosis in 2015. Eighty-three clinical questions were selected, and a literature search was performed for the clinical questions with use of the MEDLINE, Cochrane, and Igaku Chuo Zasshi databases for the period between 1983 and June 2012. Manual searching of the latest important literature was added until August 2015. The guidelines were developed with use of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. This digest version in English introduces selected clinical questions and statements related to the management of liver cirrhosis and its complications. Branched-chain amino acids relieve hypoalbuminemia and hepatic encephalopathy and improve quality of life. Nucleoside analogues and peginterferon plus ribavirin combination therapy improve the prognosis of patients with hepatitis B virus related liver cirrhosis and hepatitis C related compensated liver cirrhosis, respectively, although the latter therapy may be replaced by direct-acting antivirals. For liver cirrhosis caused by primary biliary cirrhosis and active autoimmune hepatitis, urosodeoxycholic acid and steroid are recommended, respectively. The most adequate modalities for the management of variceal bleeding are the endoscopic injection sclerotherapy for esophageal varices and the balloon-occluded retrograde transvenous obliteration following endoscopic obturation with cyanoacrylate for gastric varices. Beta-blockers are useful for primary prophylaxis of esophageal variceal bleeding. The V2 receptor antagonist tolvaptan is a useful add-on therapy in careful diuretic therapy for ascites. Albumin infusion is useful for the prevention of paracentesis-induced circulatory disturbance and renal failure. In addition to disaccharides, the nonabsorbable antibiotic rifaximin is useful for the management of encephalopathy. Anticoagulation therapy is proposed for patients with acute-onset or progressive portal vein thrombosis.

Abstract
The aim of this study is to explore the clinical application value of preoperative selective partial splenic embolization before splenectomy plus portal-azygous disconnection. 158 cases of liver cirrhosis combined with upper gastrointestinal hemorrhage patients were selected, which were randomly divided into splenic embolization group (S, n=77) and the non-splenic embolization group (U, n=81). Group S patients were firstly performed partial splenic embolization (PSE), and then underwent splenectomy plus portal-azygous disconnection, and the group U patients were directly performed splenectomy plus portal-azygous disconnection. Statistical analysis was used SAS8.0 statistical analysis software. One week after partial splenic embolization, the platelet of group S returned to normal, and the rise of white blood cells and hemoglobin, and shorten of prothrombin time in group S were much better than that in group U (P<0.01, P<0.05); the indexes, such as the intraoperative blood loss, the blood transfusion amount, the amount of platelet infusion, and the incidence of complications in group S were more superior than that in group U (P<0.05). Preoperative selective splenic artery embolization before splenectomy plus portal-azygous disconnection can restore the spleen function, and reduce the risk of surgery and incidence of complications.

Abstract
The portal vein is formed at the confluence of the splenic and superior mesenteric vein behind the head of the pancreas. Normal blood pressure within the portal system varies between 5 and 10 mmHg. Portal hypertension is defined when the gradient between the portal and systemic venous blood pressure exceeds 5 mmHg. The most common cause of portal hypertension is cirrhosis. In cirrhosis, portal hypertension develops due to extensive fibrosis within the liver parenchyma causing increased vascular resistance. In addition, the inability of the liver to metabolise certain vasodilators leads to hyperdynamic splanchnic circulation resulting in increased portal blood flow. Decompression of the portal pressure is achieved by formation of portosystemic collaterals. In this review, we will discuss the pathophysiology, anatomy, and imaging findings of spontaneous portosystemic collaterals and clinical manifestations of portal hypertension with emphasis on the role of interventional radiology in the management of complications related to portal hypertension.

Abstract
Ligation of splenic artery (LSA) is used for the treatment of liver cirrhosis with hypersplenism. However, hypersplenism is not significantly improved following LSA treatment in some cases, and there are few reports of retreatment of hypersplenism after LSA. We report the case of a 47-year-old man with liver cirrhosis and hypersplenism who underwent LSA treatment, but did not significantly improve. Laboratory tests revealed severe leukocytopenia and thrombocytopenia. Celiac computed tomography arteriogram and digital subtraction angiography revealed two compensatory arteries connected to the hilar splenic artery from the left gastro-epiploic artery and from the dorsal pancreatic artery. Partial splenic embolization (PSE) was performed through the compensatory arteries. As a result, the patient achieved partial splenic ischemic infarction, and white blood cell and platelet counts rose and remained in the normal range. PSE is an effective therapeutic modality for the retreatment of hypersplenism when other modalities have failed.

Abstract
BACKGROUND The effect of splenomegaly in patients with liver cirrhosis and portal hypertension is not fully understood. This study was designed to determine the effect of laparoscopic splenectomy on portal haemodynamics in these patients. METHODS Patients with liver cirrhosis and portal hypertension who underwent laparoscopic splenectomy in Kyushu University Hospital from January 2006 to March 2009 were evaluated retrospectively. Correlations between splenic size and portal haemodynamics, and changes in portal haemodynamics and in levels of the vasoactive agents endothelin (ET) 1 and nitric oxide metabolites (NOx) before and 7-10 days after laparoscopic splenectomy were analysed. RESULTS Portal venous (PV) blood flow, PV cross-sectional area and PV congestion index correlated significantly with splenic size (P < 0·050). All three were significantly reduced following splenectomy in 59 patients. The hepatic venous pressure gradient, measured in 18 patients, decreased by 25 per cent after splenectomy (P < 0·001). Portal vascular resistance was also reduced, by 21 per cent (P = 0·009). The peripheral blood concentration of ET-1 decreased from 2·95 to 2·11 pg/ml (P < 0·001), and that of NOx tended to decrease (from 29·2 to 25·0 pg/ml; P = 0·068). In hepatic venous blood, the level of ET-1 decreased from 2·37 to 1·83 pg/ml (P = 0·006), whereas NOx concentration tended to increase (from 24·5 to 30·9 pg/ml; P = 0·067). CONCLUSION In patients with liver cirrhosis and portal hypertension, splenectomy reduced portal venous pressure. A decrease in splanchnic blood flow, by eliminating splenic blood flow, and reduction in intrahepatic vascular resistance, by normalizing hepatic concentrations of ET-1 and NOx, may both have contributed.

Abstract
Splenomegaly is a common sequela of cirrhosis, and is frequently associated with decreased hematologic indices including thrombocytopenia and leukopenia. Partial splenic artery embolization (PSE) has been demonstrated to effectively increase hematologic indices in cirrhotic patients with splenomegaly. This is particularly valuable amongst those cirrhotic patients who are not viable candidates for splenectomy. Although PSE was originally developed decades ago, it has recently received increased attention. Presently, PSE is being utilized to address a number of clinical concerns in the setting of cirrhosis, including: decreased hematologic indices, portal hypertension and its associated sequela, and splenic artery steal syndrome. Following PSE patients demonstrate significant increases in platelets and leukocytes. Though progressive decline of hematologic indices occur following PSE, they remain improved as compared to pre-procedural values over long-term follow-up. PSE, however, is not without risk and complications of the procedure may occur. The most common complication of PSE is post-embolization syndrome, which involves a constellation of symptoms including fever, pain, and nausea/vomiting. The rate of complications has been shown to increase as the percent of total splenic volume embolized increases. The purpose of this review is to explore the current literature in regards to PSE in cirrhotic patients and to highlight their techniques, and statistically summarize their results and associated complications.
