Portal vein thrombosis (PVT) is a frequent complication of cirrhosis. Benefit, safety, and duration of anticoagulant treatment in this setting are controversial issues. The aim of this study was to ...analyze the course of PVT in a large cohort of cirrhotic patients undergoing or not anticoagulation therapy.
The data of 182 patients who presented between January 2008 and March 2016 with cirrhosis and PVT with at least 3 months of follow-up after the first PVT detection were analyzed. Eighty-one patients received anticoagulants and 101 were untreated per physician discretion.
The extension of the thrombosis decreased by >50% in 46 (56.8%, with complete recanalization in 31/46) patients under anticoagulation and in 26 (25.7%) untreated patients. Of the 46 patients who underwent recanalization, 17 (36%) suffered recurrent thrombosis after stopping anticoagulation therapy. Kaplan-Meier analysis showed a higher survival rate in the treated group (p = 0.010). At multivariate analysis, anticoagulation was an independent factor associated with longer survival (HR:0.30, CI:0.10-0.91, p = 0.014). The Child-Turcotte-Pugh classes B/C negatively influenced survival (hazard ratio, (HR):3.09, confidence interval (CI):1.14-8.36, p = 0.027 for Child-Turcotte-Pugh B and HR:9.27, CI:2.67-32.23, p < 0.001 for Child-Turcotte-Pugh C). Bleeding complications occurred in 22 (21.8%) untreated and 16 (19.7%) treated patients, but in only four cases was it judged to be related to the anticoagulant treatment. No death was reported as a consequence of the bleeding events.
Anticoagulant treatment is a safe and effective treatment leading to partial or complete recanalization of the portal venous system in 56.8% of cases, improving the survival of patients with cirrhosis and PVT. Discontinuation of the therapy is associated with a high rate of PVT recurrence.
Malignancies are generally considered a risk factor for deep vein thrombosis and may hamper the recanalisation of thrombosed veins.
We investigate whether the natural course and response to ...anticoagulant treatment of bland portal vein thrombosis (PVT) in patients with cirrhosis complicated by hepatocellular carcinoma (HCC) differ from those without HCC.
Retrospective study in two hepatology referral centres, in Italy and Romania where patients with a diagnosis of PVT on cirrhosis and follow-up of at least 3 months with repeated imaging were included.
A total of 162 patients with PVT and matching inclusion and exclusion criteria were identified: 30 with HCC were compared to 132 without HCC. Etiologies, Child-Pugh Score (7 vs 7) and MELD scores (11 vs 12, p=0.3679) did not differ. Anticoagulation was administered to 43% HCC vs 42% nonHCC. The extension of PVT in the main portal trunk was similar: partial/total involvement was 73.3/6.7% in HCC vs 67.4/6.1% in nonHCC, p=0.760. The remainder had intrahepatic PVT. The recanalization rate was 61.5% and 60.7% in HCC/nonHCC in anticoagulated patients (p=1). Overall PVT recanalisation, including treated and untreated patients, was observed in 30% of HCC vs 37.9% of nonHCC, p=0.530. Major bleeding incidence was almost identical (3.3% vs 3.8%, p=1). Progression of PVT after stopping anticoagulation did not differ (10% vs 15.9%, respectively, HCC/nHCC, p=0.109).
The course of bland non-malignant PVT in cirrhosis is not affected by the presence of active HCC. Treatment with anticoagulation in patients with active HCC is safe and as effective as in nonHCC patients, this can potentially allow us to use otherwise contraindicated therapies (ie TACE) if a complete recanalization is achieved with anticoagulation.
Purpose
Different shear wave elastography (SWE) machines able to quantify liver stiffness (LS) have been recently introduced by various companies. The aim of this study was to investigate the ...agreement between point SWE with Esaote MyLab Twice (pSWE.ESA) and 2D SWE with Aixplorer SuperSonic (2D SWE.SSI). Moreover, we assessed the correlation of these machines with Fibroscan in a subgroup of patients.
Methods
A total of 81 liver disease patients and 27 subjects without liver disease accessing the ultrasound lab were considered. Exclusion criteria were liver nodules, BMI >35, and severe comorbidities. LS was sampled from the same intercostal space with both pSWE.ESA and 2D SWE.SSI and values were tested with Lin’s analysis and Bland–Altman analysis (B&A). Agreement between each SWE machine and Fibroscan was assessed in 26 liver disease patients with Spearman correlation.
Results
Precision and accuracy between pSWE.ESA and 2D SWE.SSI were, respectively, 0.839 and 0.999. B&A showed a mean of only −0.2 kPa, with no systematic deviation between the techniques and limits of agreement at −11.6 and 11.3 kPa. Spearman’s rho correlation versus Fibroscan was 0.849 for pSWE.ESA and 0.878 for 2D SWE.SSI. The relationship became less strict in the higher range of LS (≥15.2 kPa), corresponding to cirrhosis.
Conclusion
The overall degree of concordance of pSWE.ESA and 2D SWE.SSI in measuring LS resulted remarkable, also when compared with Fibroscan. The less strict correlation for patients with LS in the higher range would not affect the staging of disease as such patients are anyhow classified as cirrhotic.
