Overview
If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
OR
Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
OR
Prognosis is generally excellent/good/poor, and the 1/5/10-year mortality/survival rate of patients with [disease name] is approximately [#]%.
Natural History
- If left untreated, 90% of patients with mesenteric ischemia may progress to develop intestinal gangrene, bowel infarction, and ultimately septic shock.
- It can be divided into three phases:
- Hyperactive phase
- Paralytic phase
- Shock
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.
Prognosis
- Mesenteric ischemia is difficult to diagnose.
- The prognosis mostly depends on prompt diagnosis and timely medical/surgical intervention depending on the underlying etiology.[3]
- Generally, the prognosis is poor when there is delay in the treatment, ranging from 0% to 40%.[4]
- In case of occlusive type of acute mesenteric ischemia, mortality can be upto 90% without surgical intervention.[5]
- In embolic type of mesenteric arterial occlusion, there is improved outcome after surgical intervention, which is not the case in thrombotic and non-occlusive type of mesenteric ischemia.
| Type of mesenteric ischemia | Survival rate | Mortality rate |
|---|---|---|
| Arterial embolism | 41% | 54% |
| Arterial thrombosis | 38% | 77% |
| Venous thrombosis | 87% | 32% |
- Venous thrombosis - 32% mortality
- Arterial embolism - 54% mortality
- Arterial thrombosis - 77% mortality
- Non-occlusive ischemia - 70-90% mortality[6]

Prognostic indicators of mesenteric ischemia:[7]
- Mannheim Peritonitis Index (MPI)
- Platelet to lymphocyte ratio
Complications
- Common complications of mesenteric ischemia include:
- Bowel infarction
- Perforation
- Sepsis
- Septic shock
- Multiorgan failure
