CT Imaging Results and Surgical Outcomes in Patients with Acute Mesenteric Ischemia
Overview
This study evaluates the relationship between CT imaging findings and surgical outcomes in patients with acute mesenteric ischemia (AMI).
Background
Acute mesenteric ischemia is a critical condition characterized by a sudden reduction in blood supply to the intestines, leading to severe complications such as bowel necrosis.
Data Highlights
Finding
Frequency
Arterial occlusive AMI
57.8%
NOMI
22.5%
Secondary/mechanical ischemia
14.7%
Venous AMI
4.9%
In-hospital mortality
41.2%
30-day mortality
46.5%
Intraoperative infarction or necrosis
81.5%
Key Findings
Arterial occlusive AMI was the most common subtype, accounting for 57.8% of cases.
In-hospital mortality was reported at 41.2%, with a 30-day mortality rate of 46.5%.
Intraoperative evidence of bowel infarction or necrosis was found in 81.5% of surgically explored patients.
No individual CT finding demonstrated strong standalone discriminatory performance for intraoperative infarction or necrosis.
Pneumatosis intestinalis showed the strongest descriptive performance for the primary endpoint.
Acute kidney injury was independently associated with increased 30-day mortality.
Clinical Implications
CT imaging is essential for diagnosing AMI and guiding treatment.
Conclusion
CT imaging remains a vital tool for diagnosis and treatment planning.
