Acute mesenteric venous thrombosis causes impaired mesenteric blood supply which may lead to bowel infarction and, in a longer perspective, severe portal hypertension. Early diagnosis, immediate anticoagulation, and active expectancy are critical for the outcome. The patients should be evaluated and treated in a multidisciplinary context, involving gastroenterologists, interventional radiologists, vascular and colorectal surgeons, and consultants in clinical coagulation. Percutaneous thrombectomy, including transjugular intrahepatic portosystemic shunt (TIPS), should be considered in cases with imminent bowel necrosis despite adequate anticoagulation, but can also serve as a complement to surgery. Here we provide a clinical overview of acute mesenteric venous thrombosis, exemplified with authentic patient cases, especially discussing the role for interventional radiology.

CiThroModel Improves Prediction of Symptomatic Venous Thromboembolism in Hospitalized Patients With Cirrhosis Without Hepatocellular Carcinoma.
United European Gastroenterol J

Department of Surgery, Oncology and Gastroenterology, University of Padova, Padova, Italy.
Background & Aims: Venous thromboembolism (VTE) is a recognized complication of acutely ill patients, but its incidence and risk factors in those with cirrhosis are uncertain.
Methods: We retrospectively studied a consecutive cohort of cirrhosis patients non-electively admitted to our medical unit to determine the rates of symptomatic VTE during hospitalization. Firstly, we explored associations with baseline, clinical and laboratory characteristics using logistic regression.

Aims: Childhood cancer is a risk factor for cardiovascular diseases in later life. Retinal examination allows to non-invasively observe the vasculature of an end-organ. We observe alterations in long-term childhood cancer survivors (CCS).

Background: Thromboembolic events are a common cause of morbidity and mortality in patients with cancer. While direct-acting oral anticoagulants (DOACs) have been established as the preferred agents of anticoagulation in most patients with cancer, data in resource-limited settings is limited.
Aims: The study aims to assess the comparative efficacy and safety of warfarin and rivaroxaban for cancer-associated thrombosis (CAT) in a resource-limited setting.
A Rare Case of Linear Phlebolith: Foreign Body Discovered in the Femoral Vein.

Division of Vascular Surgery, Department of Surgery, College of Medicine, King Saud University, Riyadh 11322, Saudi Arabia.
Phlebolith is a term that refers to round-shaped calcified thrombi commonly located in the pelvic region. The occurrence of dense, linear calcifications or phlebolith-like formations within the soft tissues of the lower extremities, particularly in the superficial femoral, greater saphenous, or popliteal veins, is rare. This study presents the case of a 73-year-old woman who was being evaluated for postmenopausal bleeding.

Introduction: A common complication of arteriovenous fistula (AVF) is thrombosis in the venous segment, which can impair vascular access unless a successful thrombectomy is performed.
Case Presentation: In this manuscript, we describe the case of a diabetic patient who had primary AVF in a snuff-box with subsequent superficialization of the medial vein of the forearm. Unfortunately, this section of the vein was occluded, although the fistula was patent through the cephalic vein (CV).
