Mesenteric Ischemia - Differential Diagnostic Schema
Chronic: ASCVD, Venous, Vasculitides 5% (PAN, [E]GPA, IgA, MPA)
Acute
 - Venous (least common): Thrombus, 1° clotting disorder, Malignancy, Hyperviscosity, Local inflammation (e.g. pancreatitis)
 - Arterial
    - Thrombus / Embolism: Cardiac (AF, LV hypo-/akinesis), ASCVD, Antiphospholipid syndrome, Endovasc surg/prosthesis, Vasculitides (inflammation → clot)
    - Hypoperfusion: Lumen (Bowel strangulation), Heart/Vessels (Heart failure, Dissection, ASCVD, True hypovolemia), Meds/Treatments (Pressors, Cardiotoxic, Hemodialysis)
