Mesenteric venous thrombosis.

Area of Science:

• Gastroenterology
• Vascular Surgery
• Hematology

Background:

• Mesenteric vein thrombosis (MVT) is an increasingly recognized cause of acute mesenteric ischemia.
• Acute MVT often presents with abdominal pain, while chronic MVT may manifest with portal hypertension.
• Predisposing factors include prothrombotic states, hematological malignancies, and abdominal inflammation.

Purpose of the Study:

• To review the diagnosis, predisposing conditions, and management of mesenteric vein thrombosis.
• To highlight the role of Janus kinase 2 (JAK-2) mutation in identifying myeloproliferative neoplasms as a cause of MVT.
• To discuss the evolving treatment strategies and their impact on patient outcomes.

Main Methods:

• Review of current literature on mesenteric vein thrombosis.
• Emphasis on diagnostic accuracy of contrast-enhanced CT scans.
• Discussion of predisposing conditions, including JAK-2 mutation associated myeloproliferative neoplasms.

Main Results:

• Contrast-enhanced CT is highly accurate for diagnosing and differentiating MVT types.
• JAK-2 mutation is a significant biomarker for myeloproliferative neoplasms, a common MVT cause.
• Anticoagulation is the mainstay treatment for acute MVT, with thrombolysis as an alternative.

Conclusions:

• Early recognition and anticoagulation have reduced the need for surgery in MVT patients.
• Improved survival rates are observed with current management strategies for MVT.
• Understanding predisposing factors like JAK-2 mutations is crucial for effective MVT management.
