Mesenteric ischaemia topics for General Physicians
How mesenteric ischemia is tested
Written for DHA, SMLE, DOH, QCHP, OMSB, MOH, NHRA and Kuwait MOH — the same GP licensing mix, not a mesenteric ischemia specialist paper.
The classic stem is severe pain with a soft abdomen, atrial fibrillation, and a lactate that does not match how “well” the tummy looks.
Early mesenteric ischaemia is a CT angiogram and a vascular/surgical call, not a second analgesic while you wait for a white-cell rise.
Occlusive embolic disease vs non-occlusive low-flow in the ICU are different pathways. Late peritonitis means dead bowel and laparotomy.
Why is the abdomen soft in the stem?
Mucosal ischaemia hurts before peritoneal inflammation. Waiting for rigidity is waiting for infarction.
Best first imaging if stable enough?
CT angiography. Plain films are too late if you already suspect the diagnosis.
AF in the history — why is it there?
Cardiac embolus to the SMA is the story they are telling. Anticoagulation comes after you have saved the bowel, not instead of imaging.
