Overview
Symptoms of chronic mesenteric ischemia caused by atherosclerosis include abdominal pain after eating and diarrhea. Symptoms of acute mesenteric artery ischemia due to an embolus include diarrhea, sudden severe abdominal pain, and vomiting.
History
Three progressive phases of ischemic colitis have been described:[1][2]
- A hyperactive phase occurs first, in which the primary symptoms are severe abdominal pain and the passage of bloody stools. Many patients get better and do not progress beyond this phase.
- A paralytic phase can follow if ischemia continues; in this phase, the abdominal pain becomes more widespread, the belly becomes more tender to the touch, and bowel motility decreases, resulting in abdominal bloating, no further bloody stools, and absent bowel sounds on exam.
- Finally, a shock phase can develop as fluids start to leak through the damaged colon lining. This can result in shock and metabolic acidosis with dehydration, low blood pressure, rapid heart rate, and confusion. Patients who progress to this phase are often critically ill and require intensive care.
Symptoms
Symptoms of mesenteric ischemia vary and can be acute (especially if embolic)[3], subacute, or chronic[4].
Case series report prevalence of clinical findings and provide the best available, yet biased, estimate of the sensitivity of clinical findings[5][6]. In a series of 58 patients with mesenteric ischemia due to mixed causes[6]:
- Abdominal pain was present in 95% (median of 24 hours duration). The other three patients presented with shock and metabolic acidosis.
- Nausea in 44%
- Vomiting in 35%
- Diarrhea in 35%
- Heart rate > 100 in 33%
- 'Blood per rectum' in 16% (not stated if this number also included occult blood - presumably not)
- Constipation 7%
