Management of splanchnic vein thrombosis.

ABSTRACT: The expression splanchnic vein thrombosis encompasses Budd-Chiari syndrome and portal vein thrombosis. These disorders have common characteristics: they are both rare diseases which can cause portal hypertension and its complications. Budd-Chiari syndrome and portal vein thrombosis in the absence of underlying liver disease share many risk factors, among which myeloproliferative neoplasms represent the most common; a rapid comprehensive work-up for risk factors of thrombosis is needed in these patients. Long-term anticoagulation is indicated in most patients. Portal vein thrombosis can also develop in patients with cirrhosis and in those with porto-sinusoidal vascular liver disease. The presence and nature of underlying liver disease impacts the management of portal vein thrombosis. Indications for anticoagulation in patients with cirrhosis are growing, while transjugular intrahepatic portosystemic shunt is now a second-line option. Due to the rarity of these diseases, studies yielding high-grade evidence are scarce. However, collaborative studies have provided new insight into the management of these patients. This article focuses on the causes, diagnosis, and management of patients with Budd-Chiari syndrome, portal vein thrombosis without underlying liver disease, or cirrhosis with non-malignant portal vein thrombosis.

Project description:Background & aimsWhether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is a risk factor for splanchnic vein thrombosis (SVT) is unknown. This study aims to assess the impact of SARS-CoV-2 infection on the presentation and prognosis of recent SVT and to identify specific characteristics of SARS-CoV-2-associated SVT.MethodsThis is a retrospective study collecting health-related data of 27 patients presenting with recent SVT in the context of SARS-CoV-2 infection in 12 Vascular Liver Disease Group (VALDIG) centres and in comparison with 494 patients with recent SVT before the SARS-CoV-2 pandemic.ResultsTwenty-one patients with SARS-CoV-2 had portal vein thrombosis with or without thrombosis of another splanchnic vein, two had superior mesenteric vein thrombosis, one had splenic vein thrombosis, and three had hepatic vein thrombosis. Diagnosis of SVT was made 10 days (95% CI 0-24 days) after the diagnosis of SARS-CoV-2 infection. Fever (52 vs. 15%; p <0.001) and respiratory symptoms (44 vs. 0%; p <0.001) were more frequent, and median lymphocyte count was lower (1.1 × 103/mm3vs. 1.6 × 103/mm3; p = 0.043) in patients with infection than in those without SARS-CoV-2 infection. A prothrombotic condition was identified in 44 and 52% of patients with and without SARS-CoV-2 infection, respectively (p = 0.5). All patients with SARS-CoV-2 received anticoagulation therapy. During a median follow-up of 250 days, three SARS-CoV-2-infected patients (11%) required intestinal resection for infarction 1 to 3 months after diagnosis of SVT compared with 13 (2.6%) controls (p = 0.044). Partial or complete recanalisation of the thrombosed splanchnic vein was performed in 33% of patients with SARS-CoV-2.ConclusionsSARS-CoV-2 infection can be associated with recent SVT. Intestinal infarction leading to intestinal resection might be more frequent in patients with SARS-CoV-2.Impact and implicationsSARS-CoV-2 infection can be associated with recent SVT. SVT occurring during SARS-CoV-2 infection is characterised by a higher frequency of respiratory symptoms and a lower lymphocyte count. Intestinal infarction leading to intestinal resection appears to occur more frequently in patients with SARS-CoV-2.

Project description:Splanchnic vein thrombosis (SVT) is not rare in patients with acute pancreatitis. It remains unclear about whether anticoagulation should be given for acute pancreatitis-associated SVT. The PubMed, EMBASE, and Cochrane Library databases were searched. Rates of SVT recanalization, any bleeding, death, intestinal ischemia, portal cavernoma, and gastroesophageal varices were pooled and compared between patients with acute pancreatitis-associated SVT who received and did not receive therapeutic anticoagulation. Pooled rates and risk ratios (RRs) with 95% confidence intervals (CIs) were calculated. Heterogeneity among studies was evaluated. Overall, 16 studies including 698 patients with acute pancreatitis-associated SVT were eligible. After therapeutic anticoagulation, the pooled rates of SVT recanalization, any bleeding, death, intestinal ischemia, portal cavernoma, and gastroesophageal varices were 44.3% (95%CI = 32.3%-56.6%), 10.7% (95%CI = 4.9%-18.5%), 13.3% (95%CI = 6.9%-21.4%), 16.8% (95%CI = 6.9%-29.9%), 21.2% (95%CI = 7.5%-39.5%), and 29.1% (95%CI = 16.1%-44.1%), respectively. Anticoagulation therapy significantly increased the rate of SVT recanalization (RR = 1.69; 95%CI = 1.29-2.19; P < .01), and marginally increased the risk of bleeding (RR = 1.98; 95%CI = 0.93-4.22; P = .07). The rates of death (RR = 1.42; 95%CI = 0.62-3.25; P = .40), intestinal ischemia (RR = 2.55; 95%CI = 0.23-28.16; P = .45), portal cavernoma (RR = 0.51; 95%CI = 0.21-1.22; P = .13), and gastroesophageal varices (RR = 0.71; 95%CI = 0.38-1.32; P = .28) were not significantly different between patients who received and did not receive anticoagulation therapy. Heterogeneity was statistically significant in the meta-analysis of intestinal ischemia, but not in those of SVT recanalization, any bleeding, death, portal cavernoma, or gastroesophageal varices. Anticoagulation may be effective for recanalization of acute pancreatitis-associated SVT, but cannot improve the survival. Randomized controlled trials are warranted to further investigate the clinical significance of anticoagulation therapy in such patients.
