A 70-year-old man with diabetic triopathy was hospitalized with left l
ower quadrant abdominal pain and tenderness, muscle guarding and absen
t bowel sounds. Three hours after admission, creatine phosphokinase (C
PK) was elevated and an abdominal plain film X-ray showed intestinal g
as retention, indicating paralytic ileus due to inferior mesenteric ar
tery occlusion, Urokinase (60,000 units/day) and heparin (10,000 units
/day) were administered. Angiography showed no occlusion in the mesent
eric artery. On the 16th day, the abdominal signs had disappeared and
CPK was normalized. We diagnosed this case as nonocclusive colonic isc
hemia because of the hemorheological abnormalities due to diabetic tri
opathy and the hypercoagulable state.
