Diagnosis and management of splanchnic ischemia

Figure 4 Imminent ASS and normal gastric and jejunal PCO₂ pattern. A: Normal 24 h PCO₂ pattern in the stomach (squares) and jejunum (diamonds) with variation in PCO₂, but no peaks above 11 kPa following meals; B: Imminent bowel infarction in a patient with severe 3 vessel CSS. After her evening meal she had pain for almost 6 h, and extreme ischemia with PCO₂ > 16 kPa for 7 h. She was treated with endovascular stent placement the day after this measurement, with immediate relief of complaints. She is still doing well, over 3 years later.
