Mesentric ischemia vessels

 Q: Mesenteric ischemia is more common in which bed of the vessels? (select one) 

A) arterial 

B) venous

Answer: A

Abdominal angina was first described more than a century ago. Logic may argue that passive velocity may be the major cause of mesenteric ischemia but actually, it is arterial embolism which is responsible half of the time (50 percent) for mesenteric ischemia, followed by nonocclusive mesenteric ischemia (20 percent). Arterial and venous thrombosis are equally responsible (15 percent each) for mesenteric ischemia. In fact, mesenteric venous thrombosis has a slower course and lower mortality. The rate of the flow itself doesn't make any difference but the underlying systemic diseases are more responsible for this pathology. It includes age, atherosclerosis, low cardiac output (CHF), atrial fibrillation), cardiac valvular pathologies, and intraabdominal malignancy.
