Abstract
Hepatic sinusoidal obstruction syndrome (HSOS) is a hepatic vascular disease histologically characterized by edema, necrosis, detachment of endothelial cells in small sinusoidal hepatic and interlobular veins and intrahepatic congestion, which leads to portal hypertension and liver dysfunction. In the Western world, most HSOS cases are associated with myeloablative pretreatment in a hematopoietic stem cell transplantation setting. Here we report a case of a 54 years old female patient, otherwise healthy, with no history of alcoholic ingestion, who presented with jaundice and signs of portal hypertension, including ascites and bilateral pleural effusion. She had no history of liver disease and denied any other risk factor for liver injury, except Senecio brasiliensis ingestion as a tea, prescribed as a therapy for menopause. Acute viral hepatitis and thrombosis of the portal system were excluded in complementary investigation, as well as sepsis, metastatic malignancy and other liver diseases, setting a RUCAM score of 6. Computed tomography demonstrated a diffuse liver parenchymal heterogeneity (in mosaic) and an extensive portosystemic collateral venous circulation, in the absence of any noticeable venous obstruction. HSOS diagnosis was confirmed through a liver biopsy. During the following-up period, patient developed refractory pleural effusion, requiring hemodialysis. Right before starting anticoagulation, she presented with abdominal pain and distention, with findings compatible of mesenteric ischemia by computed tomography. A laparotomy was performed, showing an 80cm segment of small bowel ischemia, and resection was done. She died one day after as a result from a septic shock refractory to treatment. The presented case was related to oral intake of S. brasiliensis, a plant containing pyrrolidine alkaloids, which are one of the main causes of HSOS in the East, highlighting the risk of liver injury with herbs intake.

Abstract
Hepatic veno-occlusive disease (VOD) is a significant cause of morbidity and mortality in captive cheetahs (Acinonyx jubatus), and the appearance of this disease in humans by computed tomography (CT) has been well described. Contrast-enhanced CT abdominal scans of cheetahs without evidence of hepatic disease (n = 5) were reviewed retrospectively to describe the normal appearance of cheetah livers as an aid to antemortem VOD diagnosis. Despite having no clinical signs, clinical pathology abnormalities, or hepatic biopsy histopathology supportive of VOD, all five cheetahs had at least one VOD consistent finding on CT. The results of this study suggest that given the progressive and potentially subclinical nature of VOD, CT could serve as a noninvasive screening tool and be used to monitor disease progression.

Abstract
Sinusoidal obstruction syndrome (SOS) is a rare liver disorder due to hepatic vascular injury. Its rapid and accurate diagnosis is crucial for patient survival. SOS is often established clinically, based on Baltimore, modified Seattle, or European Society for Blood and Marrow Transplantation (EBMT) criteria. Unfortunately, such criteria are not highly specificity and fail to provide a timely, reliable differential diagnosis. The use of noninvasive imaging techniques, such as ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI), and fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT), has recently grown in this setting, some key imaging features offering diagnostic improvement. This review provides a synopsis of current noninvasive imaging techniques used for this purpose, summarizing accurate and reliable diagnostic features of SOS.

Abstract
Veno-occlusive-disease (VOD), known also as sinusoidal-obstruction-syndrome (SOS), is one of the main complications of haematopoietic stem cell transplantation and is related to the treatment with pyrrolizidine alkaloids or other toxic agents (chemotherapy for liver-metastasis). Clinical diagnosis using the recent criteria from the European Society for Blood and Marrow Transplantation, is the reference for VOD/SOS diagnosis. However, increasing evidence suggests the emerging role of several imaging methods that could help the clinician in VOD/SOS assessment. Areas covered: This review evaluates the current literature on the various imaging techniques used in VOD/SOS diagnosis in several clinical scenarios. Literature searches were performed using several keywords on MEDLINE/Ovid/In-Process/Cochrane Library/EMBASE and PubMed up to July 2018. Expert commentary: Hepatic-gradient-measurement (HVPG) and contextual transjugular-liver-biopsy are invasive and should always be considered in unclear cases. The main studies revolve around ultrasound with Doppler evaluation, identifying numerous findings suggestive of VOD/SOS. However, their accuracy and validation are still suboptimal and controversial. CT-Scan and MRI have shown encouraging data in other contexts in which VOD/SOS can develop, but studies on the post-HSCT patient are lacking. Elastography techniques measuring liver stiffness (LSM) represent the most recent and promising approach for an accurate and early diagnosis of VOD/SOS. In our view, a multidisciplinary approach to the VOD/SOS diagnosis should be highly encouraged.

Abstract
Hepatic sinusoidal obstruction syndrome (HSOS) is a hepatic vascular disease presenting with abdominal distension, pain in the hepatic region, ascites, jaundice, and hepatomegaly. In China, this disease is often associated with the oral intake of plants that contain pyrrolidine alkaloids. The existing guidelines are limited to HSOS associated with hematopoietic stem cell transplantation in Western countries. The Hepatobiliary Diseases Committee of the Chinese Society of Gastroenterology convened an expert consensus conference on the diagnosis and treatment of PA-HSOS to evaluate current research in China and abroad. The "Nanjing criteria" developed by the committee to diagnose PA-HSOS include a confirmed history of PA-containing plant use and (i) abdominal distention and/or pain in the hepatic region, hepatomegaly, and ascites; (ii) elevation of serum total bilirubin or abnormal laboratory liver tests; (iii) evidence on enhanced computed tomography or magnetic resonance imaging; or (iv) pathological evidence that rules out other known causes of liver injury. Supportive symptomatic treatment, anticoagulant therapy, and placement of a transjugular intrahepatic portosystemic shunt for patients who do not respond to medical treatment are effective for the treatment of PA-HSOS. The benefits of glucocorticoids and prostaglandin E1 in PA-HSOS are not clear.

Abstract
This study evaluated hepatic lesion volumes on contrast-enhanced computed tomography (CT) images in patients with pyrrolizidine alkaloid-induced sinusoidal obstruction syndrome (PA-SOS) and the association of lesion volume with the clinical severity and prognosis of the disease. Twenty-five patients with PA-SOS were included in this study, and all patients were subjected to a complete CT imaging series. The imaging results were quantitatively analyzed by a threshold-based region growing algorithm. The liver volumes and hepatic lesion volumes of the patients were estimated. Based on clinical presentations, PA-SOS was classified into three categories: mild, moderate and severe. The associations of hepatic lesion volumes with liver function test parameters and the clinical severity and prognosis of the disease were analyzed. Based on estimations using the threshold-based region growing algorithm, hepatic lesion volumes in patients with mild PA-SOS were significantly lower than those in patients with moderate and severe PA-SOS (P < 0.05). The ratio of hepatic lesion volume to liver volume (Ratio) varied based on alanine aminotransferase (ALT), aspartate aminotransferase (AST) and serum total bilirubine levels; clinical severity; and disease prognosis, and the differences were statistically significant (P < 0.05). In conclusion, the threshold-based region growing algorithm can be employed to quantitatively analyze enhanced CT images of PA-SOS patients. And the ratio of hepatic lesion volume to liver volume in patients with PA-SOS is associated with a more serious clinical course and a poorer outcome.

Abstract
Hepatic sinusoidal obstruction syndrome (HSOS), previously known as hepatic veno-occlusive disease, is a kind of vascular disorder of the liver. HSOS is caused by toxic destruction of hepatic sinusoidal endothelial cells. Major etiologies of HSOS include hematopoietic stem cell transplantation, oxaliplatin-containing chemotherapy, intake of pyrrolizidine alkaloid-containing herbal remedies, etc. There have been many studies on the imaging manifestations of HSOS in recent years. This paper summarizes the imaging manifestations of HSOS by reviewing the latest literature and our work.

Abstract
Background Hepatic veno-occlusive disease (HVOD) caused by Gynura segetum has been increasingly reported in China in recent years. The aim of this retrospective study was to identify independent prognostic markers for survival in patients with Gynura segetum-induced HVOD and to evaluate the effect of anticoagulants and transjugular intrahepatic portosystemic shunt (TIPS) on survival rate. Methods Clinical data including symptoms, signs, imaging characteristics, laboratory test results, results of liver tissue biopsies, type of treatment during follow-up and clinical outcomes were collected. Univariate, multivariate and time-dependent Cox regression analyses were performed. Results Survival rates were 91% (95% confidence interval [CI], 82–95%), 64% (95% CI, 53–69%) and 57% (95% CI, 51–65%) at 1, 3 and 60 months, respectively. Total bilirubin, albumin and hepatic encephalopathy were independent prognostic markers of survival. Anticoagulants were administered to 76% of the patients. Among 75 patients treated with anticoagulants, 49 patients (65.3%) were cured, whereas 26 patients (34.7%) died; the cure rate in anticoagulant-treated patients was higher than that of those not treated with anticoagulants (χ2 = 9.129, P = 0.004). Cure rate of the anticoagulation + TIPS treatment group was 64.3%, which was also higher than that of the non-anticoagulation group; however, this was not significantly different (χ2 = 3.938, P = 0.096). Conclusions The presence of hepatic encephalopathy, serum bilirubin and albumin levels were major prognostic factors for Gynura segetum-induced HVOD. Anticoagulation therapy significantly increased the cure rate; however, TIPS treatment did not have a beneficial effect on the cure rate.

Abstract
RATIONALE Hepatic vein occlusive disease (HVOD) is a rare complication after liver transplantation, which is characterized by nonthrombotic, fibrous obliteration of the small centrilobular hepatic veins by connective tissue and centrilobular necrosis in zone 3 of the acini. HVOD after solid organ transplantation has been reported; recently, most of these reports with limited cases have documented that acute cell rejection and immunosuppressive agents are the major causative factors. HVOD is relatively a rare complication of liver transplantation with the incidence of approximately 2%. PATIENT CONCERNS A 59-year-old male patient with alcoholic liver cirrhosis underwent liver transplantation in our center. He suffered ascites, renal impairment 3 months after the surgery while liver enzymes were in normal range. DIAGNOSES Imagining and pathology showed no evidence of rejection or vessels complications. HVOD was diagnosed with pathology biopsy. INTERVENTIONS Tacrolimus was withdrawn and the progression of HVOD was reversed. OUTCOMES Now, this patient has been followed up for 6 months after discharge with normal liver graft function. LESSONS The use of tacrolimus in patients after liver transplantation may cause HVOD. Patients with jaundice, body weight gain, and refractory ascites should be strongly suspected of tacrolimus related HVOD.

Abstract
RATIONALE AND OBJECTIVE The computed tomography (CT) features of hepatic veno-occlusive disease (HVOD) could play a role in its diagnosis. We aimed to perform a meta-analysis of studies examining the CT features of HVOD. METHODS Relevant studies published up to May 3, 2017 were searched in major electronic databases. The extracted data included the proportion of various CT features in patients with HVOD. The meta-analysis was conducted using R 3.3.3 with the "meta" package. RESULTS Eleven studies were included. The studies involved 326 patients with a mean age range of 50.2-58.9 years, and the proportion of female patients ranged from 20% to 57.5%. The meta-analysis showed the pooled proportion of CT features: hepatic parenchyma with heterogeneous hypoattenuation (81.05%, 95% confidence interval [CI]: 56.97%-93.25%), patchy enhancement in the portal venous phase (87.09%, 95% CI: 75.15%-93.77%) with or without a narrow or invisible hepatic vein (71.02% 95% CI: 42.09%-89.20%), gallbladder wall edema (65.51%, 95% CI: 28.98%-89.84%), and patchy heterogeneous enhancement in the arterial phase (44.36%, 95% CI: 29.98%-59.76%) with or without slightly enlarged hepatic artery (56.61%, 95% CI: 40.62%-71.33%). CONCLUSION Hepatic parenchyma with heterogeneous hypoattenuation and patchy enhancement with or without narrowing or an invisible hepatic vein in the portal venous or equilibrium phase may be the most important CT feature for diagnosing HVOD.

Abstract
The aim of this study was to determine usefulness of measurements of maximal systolic velocity of the hepatic artery with Doppler ultrasonography in the diagnosis of venoocclusive disease (VOD) after hematopoietic stem cell transplantation. We prospectively obtained 5 sonograms per patient: pretransplantation, day +1, +7, +14, and +28 on 36 nonconsecutive children who underwent hematopoietic stem cell transplantation. We examined the hepatic artery, the portal, hepatic and splenic veins, the thickness of the gallbladder wall, the presence of ascites, and the liver and spleen size. The diagnosis of VOD was based on clinical and laboratory data. Patients were divided into 2 groups: those with VOD (n=18) and those without VOD (n=18). The variance of 2 groups was analyzed. Vmax of the hepatic artery had a strong correlation with clinical VOD diagnosis (P<0.001). There was no statistically significant difference in the other Doppler parameters. The results of our study showed that the measurement of Vmax of the hepatic artery can provide important support in the diagnosis of VOD and can be useful in the follow-up of treatment response.

Abstract
Hepatic sinusoidal obstruction syndrome (SOS), a serious complication that mainly occurs after hematopoietic-stem cell transplantation (HSCT), is caused by damage to the sinusoidal endothelial cells after the obstruction of the sinusoid. Recently, hepatic SOS was reported to occur after non-HSCT chemotherapies. This report describes a patient who experienced hepatic SOS after non-HSCT chemotherapy for non-Hodgkin lymphoma. A liver biopsy showed the slight dilatation of the hepatic sinusoid, which may be indicative of hepatic SOS. Hepatic SOS should be included in the differential diagnosis of patients with severe liver injury following the administration of chemotherapy regimens that are toxic to the vascular endothelial cells.
