Abstract
INTRODUCTION Spontaneous portosystemic shunts (SPSS) are frequent in liver cirrhosis and their prevalence increases as liver function deteriorates, probably as a consequence of worsening portal hypertension, but without achieving an effective protection against cirrhosis complications. This study was conducted to detect the prevalence of portosystemic shunts in liver cirrhosis patients and analyze its prognostic role. METHOD We conducted a prospective observational study, where 92 patients with decompensated cirrhosis were evaluated based on history, physical examination, biochemical tests and abdominal computed tomography (CT) angiography findings. A follow-up was done after six months for the development of cirrhosis-related complications. RESULTS Of the 92 cirrhotic patients, 57.6% had SPSS (large SPSS + small SPSS) detected by multi-detector computed tomographic angiography. Overall, we found large SPSS in 24 (26.1%) patients, small SPSS in 29 (31.5%) patients and no shunt in 39 (42.4%) patients. Among the shunts, the splenorenal shunt is the most frequent type (25, 27.2%) followed by the paraumbilical shunt (20.7%). Previous decompensating events, including hepatic encephalopathy, ascites, spontaneous bacterial peritonitis and gastrointestinal bleed, were experienced more frequently by the large SPSS group followed by the small SPSS and without SPSS groups. Regarding follow-up, decompensating episodes of hepatic encephalopathy developed more frequently in patients with large SPSS (41.7%) than in patients with small SPSS (24.1%) followed by patients without SPSS (12.8%). CONCLUSION In summary, all cirrhotic patients should be studied with radiological imaging to detect the presence of portosystemic shunts. In several cases, patients with large SPSS had a more impaired liver function and more frequent complications of portal hypertension. So, these patients would probably benefit from a closer surveillance and more intensive therapy.

Abstract
BACKGROUND Spontaneous portosystemic shunt (SPSS) other than esophago-gastric varices is one of the consequences of cirrhosis-induced portal hypertension (PHT), but its role is not fully understood. Therefore, we conducted a systematic review and meta-analysis to determine the prevalence and clinical characteristics of SPSS (excluding esophago-gastric varices) and its impact on mortality in patients with cirrhosis. METHODS Eligible studies were identified from MedLine, PubMed, Embase, Web of Science, and Cochrane Library between Jan 1, 1980 and Sep 30, 2022. Outcome indicators were SPSS prevalence, liver function, decompensated events, and overall survival (OS). RESULTS Totally, 2015 studies were reviewed, of which 19 studies recruiting 6884 patients were included. On pooled analysis, the prevalence of SPSS was 34.2% (26.6%∼42.1%). SPSS patients had significantly higher Child-Pugh scores and grades and Model for End-stage Liver Disease scores (all P<0.05). Moreover, SPSS patients experienced a higher incidence of decompensated events, including hepatic encephalopathy, portal vein thrombosis, and hepatorenal syndrome (all P<0.05). Additionally, SPSS patients had significantly shorter OS than the non-SPSS group (P<0.05). CONCLUSIONS In patients with cirrhosis, SPSS outside the esophago-gastric region is common, characterized by severe impairment of liver function, high rates of decompensated events, including HE, PVT, and hepatorenal syndrome, as well as a high mortality rate.

Friend or Foe? Spontaneous Portosystemic Shunts in Cirrhosis-Current Understanding and Future Prospects. Can J Gastroenterol Hepatol 2021; 2021:8795115.

Abstract
Portal hypertension (PHT) in cirrhosis results from increased resistance to splanchnic blood flow secondary to parenchymal and vascular changes within the liver. In an attempt to counteract the increased portal pressure, two mechanisms simultaneously occur: splanchnic vasodilatation and formation of spontaneous portosystemic shunts (SPSS). Long considered to be a compensatory mechanism to decompress the portal venous system, it is now well established that SPSS are not only inefficient in decreasing the portal pressure but also contribute to reduced hepatocyte perfusion and increased splanchnic blood flow and resistance, associated with worsening PHT. Recent studies have described a high prevalence of SPSS in cirrhosis patients, increasing with liver dysfunction, and observed an association between the presence of SPSS and worse clinical outcomes. In cirrhosis patients with preserved liver functions, the presence of SPSS independently increases the risk of hepatic encephalopathy, variceal bleeding, and ascites, and reduces transplant-free survival. Moreover, the presence of SPSS in patients undergoing transjugular intrahepatic portosystemic shunting and liver transplant has been shown to variably affect the postprocedural outcome. This article provides an overview of the current understanding of the role of SPSS in the natural history of liver cirrhosis and their status as a therapeutic target and an imaging biomarker to identify patients at higher risk of developing complications of PHT.

Abstract
BACKGROUND AND AIM Spontaneous splenorenal shunt (SSRS) is one of the manifestations of portal hypertension in liver cirrhosis. However, the impact of SSRS on long-term survival of cirrhotic patients remains unclear. We hypothesize that SSRS may worsen liver dysfunction and deteriorate prognosis in liver cirrhosis by decreasing hepatic perfusion. METHODS Patients with liver cirrhosis who were admitted to our department between December 2014 and August 2019 and underwent contrast-enhanced computed tomography or magnetic resonance imaging scans were prospectively collected. The maximum diameters of SSRS and portal vein system vessels were retrospectively measured. Liver-to-abdominal area ratio, Child-Pugh, and model for end-stage liver disease scores were calculated. RESULTS Overall, 122 cirrhotic patients were included. The prevalence of SSRS was 30.3% (37/122). Median diameter of SSRS was 13.5 mm. Patients with SSRS had significantly thinner diameters of right portal vein (9 mm vs 11.2 mm, P = 0.001) and main portal vein (15.3 mm vs 16.8 mm, P = 0.017) than those without SSRS. Patients with SSRS had significantly lower liver-to-abdominal area ratio score (25.39 vs 31.58, P < 0.001) and higher Child-Pugh (7 vs 6, P = 0.046) and model for end-stage liver disease (12.17 vs 9.79, P < 0.006) scores than those without SSRS. Patients with SSRS had a significantly lower cumulative survival rate than those without SSRS (P = 0.014). Cox regression analysis also showed that SSRS was a risk factor of death of cirrhotic patients (hazard ratio = 4.161, 95% confidence interval = 1.215-14.255, P = 0.023). CONCLUSIONS Spontaneous splenorenal shunt may narrow portal vein diameter and shrink liver volume, thereby worsening liver function and increasing mortality in liver cirrhosis.

Abstract
Portal hypertension is the main consequence of liver cirrhosis, leading to severe complications such as variceal hemorrhage, ascites or hepatic encephalopathy. As an attempt to decompress the portal venous system, portal flow is derived into the systemic venous system through spontaneous portosystemic shunts (SPSSs), bypassing the liver. In this review, we aim to provide an overview of the published reports in relation to the prevalence and physiopathology behind the appearance of SPSS in liver cirrhosis, as well as the complications derived from its formation and its management. The role of SPSS embolization is specifically discussed, as SPSSs have been assessed as a therapeutic target, mainly for patients with recurrent/persistent hepatic encephalopathy and preserved liver function. Furthermore, different aspects of the role of SPSS in liver transplantation, as well as in candidates for transjugular intrahepatic portosystemic shunt are reviewed. In these settings, SPSS occlusion has been proposed to minimize possible deleterious effects, but results are so far inconclusive.

Abstract
Vascular diseases of the spleen are relatively uncommon in the clinical practice. However, the reported incidence has been progressively increasing, probably due to advances in the imaging modalities used to detect them. This disease condition often presents with non-specific clinical manifestations, but can be associated with significant morbidity and mortality. This review article aims to provide updated clinical information on the different vascular diseases of the splenic vasculature-splenic vein thrombosis, splenic vein aneurysm, splenic artery aneurysm, splenic arteriovenous fistula, and spontaneous splenorenal shunt-in order to aid clinicians in early diagnosis and management.

Abstract
OBJECTIVE To examine the clinical effect of splenorenal shunt (SRS) on the long-term outcomes in patients with cirrhosis. METHODS The study consisted of 162 cirrhosis patients (male 85, female 77; 62.6 ± 11.7 years). The clinical findings and prognosis were examined with respect to portal hemodynamics including collateral vessel patterns, with or without the presence of SRS or short gastric vein (SGV). Median observation period was 30 months. RESULTS The incidence was 18.5% for SRS and 10.5% for SGV. Decompensated cirrhosis was significantly more frequent in patients with SRS (22/30) than those with SGV (5/17, p = 0.0034), and in patients with SRS >5.5 mm (14/15) or >95 ml/min (14/15) (both, median values) than those with SRS <5.5 mm (8/15, p = 0.013) or <95 ml/min (8/15, p = 0.013). Cumulative overall survival rate was 87.4% at 1 year, 73.4% at 3 years, and 59.1% at 5 years. There was no significant difference in the cumulative survival rate according to the development of SRS: 80% at 1 year, 66.6% at 3 years, and 58.3% at 5 years in patients with SRS; 94.1% at 1 year, 87.4% at 3 years, and 72.8% at 5 years in patients with SGV; 88.3% at 1 year, 73.1% at 3 years, and 58% at 5 years in patients without SGV/SRS; 94.1% at 1 year, 87.4% at 3 years, and 72.8% at 5 years in patients with SGV (overall, p = 0.2). CONCLUSION In spite of no significant effect on the prognosis in cirrhosis, careful management may be necessary for the patients with SRS because of potential poor liver function demonstrated by the close linkage between the presence of SRS and decompensation.
