“…Portal vein system thrombosis (PVST) refers to the blood clots in the portal vein, splenic and superior mesenteric veins, or intrahepatic portal vein branches because they form an interactive vascular system without valves (1). PVST was first reported in 1895 by Beeckman Delatour (2), and its clinical manifestations include asymptomatic to symptomatic fever, abdominal pain, nausea, vomiting, and ileus (3).…”

Background/Aims: This study aimed to investigate the incidence and risk factors of portal vein system thrombosis (PVST) in patients with liver cirrhosis after splenectomy and pericardial devascularization. Materials and Methods: We retrospectively analyzed 71 patients who underwent splenectomy with pericardial devascularization for portal hypertension due to cirrhosis. Patients were categorized into Group A (n=23): early prophylactic anticoagulants therapy; Group B (n=29): late prophylactic anticoagulants therapy; and Group C (n=19): no anticoagulation therapy. Univariate and multivariate analyses of the risk factors of PVST were performed. The incidence of PVST and the effect of thrombolytic therapy were evaluated. Results: Multivariate analysis revealed a wider preoperative splenic vein diameter (≥8 mm), and lower preoperative platelet counts (<50×10

“…Many of these disorders are associated with specific, acquired risk factors such as nephrotic syndrome in renal vein thrombosis [15], myeloproliferative disorders in Budd-Chiari syndrome [16], liver cirrhosis or hepatocarcinoma in portal vein thrombosis [17], cancer and central venous catheters in vena cava thrombosis [18] and head injury, mastoiditis or otitis in cerebral vein thrombosis [19]. The most well-known example of a rare form of VTE is Trousseau's syndrome.…”

Zöller B, Li X, Sundquist J, Sundquist K. (Center for Primary Health Care Research, Lund University, Malmö, Sweden; Stanford Prevention Research Center, Stanford University School of Medicine, Stanford, CA, USA). Familial risks of unusual forms of venous thrombosis: a nationwide epidemiological study in Sweden. J Intern Med 2011; 270: 158–165. Abstract. Objective. This is the first nationwide study to determine familial risks of unusual forms of venous thrombosis amongst offspring of affected parents and amongst siblings. Design and settings. The Swedish Multigeneration Register of 0‐ to 75‐year‐old subjects was linked to the Hospital Discharge Register for the period 1987–2007. Standardized incidence ratios (SIRs) were calculated for individuals whose relatives were hospitalized for venous thromboembolism (VTE), as determined by the International Classification of Diseases, compared to those whose relatives were not affected by VTE. Results. The total number of hospitalized patients with VTE was 45 362, of which 1824 (4.0%) were affected by a rare thrombotic condition. The familial SIRs in cases with a history of VTE in parents or siblings were significantly increased for migrating thrombophlebitis (1.81; 95% confidence interval (CI) 1.40–2.31), portal vein thrombosis (2.35; 95% CI 1.77–3.06), vena cava thrombosis (1.96; 95% CI 1.42–2.64) and cerebral venous thrombosis (1.74; 95% CI 1.30–2.28). Budd–Chiari syndrome (SIR, 0.92; 95% CI 0.24–2.38) and renal vein thrombosis (SIR, 1.72; 95% CI 0.62–3.77) were not significantly associated with parental or sibling history of VTE; however, these two conditions were very rare, and therefore, we cannot draw any definite conclusions from this finding. Conclusions. Family history is an important risk factor for most unusual forms of VTE. Moreover, even the paraneoplastic phenomenon, migrating thrombophlebitis (Trousseau’s syndrome), is associated with a family history of VTE. Thus, our data suggest that most rare forms of VTE have a familial background.

Portal vein thrombosis with contrast‐enhanced ultrasound in a patient with hepatocellular carcinoma: a case study

Portal vein thrombosis (PVT) is the presence of thrombus in the portal vein that causes partial or complete occlusion. It is prevalent in hepatocellular carcinoma (HCC), where it can be either bland or malignant depending on the presence of invasion. Recent studies have identified contrast‐enhanced ultrasound (CEUS) as the most reliable method of imaging to make this distinction. The arterial neovascularisation that is evident in a neoplastic thrombus can be visualised on CEUS with enhancement and pulsation, witnessed in real‐time. This case study describes the use of contrast‐enhanced ultrasound used as a non‐invasive method to define the bland and malignant components of portal vein thrombosis in a 76‐year‐old male with hepatocellular carcinoma and cirrhosis.
