[Nonobstructive intestinal ischemia].
Acute or chronic intestinal ischaemia can be the consequence of either intrinsic vascular disease, systemic disease, drugs or surgical procedures. In one quarter of the patients with intestinal ischemia, no major vascular obstructions can be detected. Very rarely, the cause of ischaemia is splanchnic vasoconstriction due to cardiac arrhythmias or sepsis. The bowel becomes ischaemic as a result of underperfusion. The clinical picture resembles the one of occlusive intestinal ischaemia. From the pathological standpoint, the ischaemia is more intense on the antimesenteric border of the bowel and the lesions are more advanced in the mucosal than in the serosal layer. Often, the ischaemia involves other organs too: liver, spleen or gallbladder. The reconstructive vascular procedures are inefficient, the only therapeutical options remains the resection of the infarcted bowel, together with other organs involved in the ischaemic process. The mortality rate approaches 90%.
