A free full text review is available from Mayo Clinic Proceedings.
Just a few points of interest:
Think of it when the patient's pain “seems real” and is out of proportion to physical findings.
Pain reaches maximum intensity relatively slowly whereas in acute mesenteric arterial occlusion maximum intensity occurs within minutes or even seconds.
Risk factors for arterial occlusion are cardiovascular---atrial fibrillation and atherosclerosis, whereas for MVT a structural or inflammatory abdominal process is often the underlying cause. Absent that, and in many cases, MVT is a disease of thrombophilia, We are taught to think thrombophilia when clots occur in unusual places. In MVT myeloproliferative disorders, with JAK2 mutation as a marker, stand out.
More about the JAK2 mutation can be found here.
Early anticoagulation improves outcomes. The degree of GI bleeding typically associated with MVT is seldom a contraindication.
Indications for surgical intervention are discussed.
