Eligibility
Inclusion criteria
Inclusion criteria: - Patients >= 18 years - Patients with a clinical suspicion of CMI referred to the hospital
Exclusion criteria
Exclusion criteria: - Patients who are unable to give informed consent - No available CT imaging and contraindications for CT imaging (e.g. pregnancy) - Patients with previous mesenteric artery revascularization - Common origin of the celiac artery and superior mesenteric artery - Known delayed gastric emptying - Known and untreated small intestinal bacterial overgrowth
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1) MACS: An existing abdominal CT is used to calculate the MACS of the celiac artery and superior mesenteric artery. 2) Butyrate breath testing: Patients will receive 13C-butyrate dissolved in a high caloric drink (Nutridrink). Multiple test tubes filled with expired air of 13CO2 will be collected during a period of 2 hours. | — |
Secondary
| Measure | Time frame |
|---|---|
| - To determine cut of values for the MACS with high specificity and high negative predictive value. - To validate the symptom and CT based MACS score chart for early risk stratification of patients with suspected CMI. - To investigate how CMI affects the gut microbioma and which specific microbial DNA fragments in blood can indicate ischemic damage to the intestinal tissue measured before and after stentplacement - To assess if specific DNA fragments in blood, associated with cell death due to ischemia, could serve as potential biomarkers for the severity and presence of CMI - To investigate the difference of cytokeratin fragments in blood before and after stent placement, and which fragments can serve as diagnostic markers for the type and location of cell death in intestinal ischemia? | — |
