Acute primary mesenteric venous thrombosis: A case report and literature review

Introduction and importance

Mesenteric vein thrombosis (MVT) is a pathological condition characterized by the obstruction of blood flow caused by the formation of new thrombi in the mesenteric veins, resulting in the development of intestinal ischemia due to the absence of collateral circulation. The insidious onset, clinical manifestations and lack of specificity of laboratory tests are significant factors that impede the timely diagnosis of MVT in clinical setting.

Case presentation

This article critically examined the pathogenesis, diagnosis and treatment of a 60-year-old male patient with MVT, while also exploring the etiology, clinical manifestations, diagnostic approaches and management advancement with MVT.

Clinical discussion

We determined that CT angiography serves as a pivotal method for early detection of MVT. Proactive anticoagulation strategy utilizing unfractionated heparin or low molecular weight heparin can notably decrease the mortality rate of patients afflicted with MVT and enhance the clinical outcome.

Conclusion

Surgery is generally not endorsed as the preferential therapeutic intervention for mesenteric venous thrombosis, barring patients with concurrent intestinal necrosis or perforation.
