ICD-11 code : DD31.0;
Preferred Label : Non-occlusive mesenteric ischaemia;
ICD-11 definition : Non-occlusive mesenteric ischaemia causes 20% to 30% of acute mesenteric ischaemia
episodes. Mesenteric ischaemia without anatomic arterial or venous obstruction is
due to mesenteric vasospasm, which can occur during periods of relatively low mesenteric
flow, especially if there is underlying arterial atherosclerotic disease. Such low-flow
state can result from heart failure, hypotension, or hypovolemia.;
ICD-11 synonym : NOMI - [non-occlusive mesenteric ischaemia];

ICD-11 inclusion : chronic mesenteric ischaemia; mesenteric artery insufficiency; SMAS - [superior mesenteric artery syndrome]; mesenteric ischaemia; mesenteric angina; mesenteric artery syndrome; vascular insufficiency of the mesentery; mesenteric vascular insufficiency syndrome; mesenteric arteriosclerosis; CMI - [chronic mesenteric ischaemia]; mesenteric arterial syndrome; mesenteric arterial insufficiency;
