Learning objectives Provide a comprehensive overview of mesenteric ischemia, highlighting both acute and chronic forms. Describe the clinical and imaging features of different types of acute mesenteric ischemia, including arterial occlusive (embolic, thrombotic), non-occlusive, and veno-occlusive ischemia. Discuss chronic mesenteric ischemia and its diagnostic challenges. Illustrate the imaging findings through case studies from our hospital.
Read more Background Mesenteric ischemia, characterized by insufficient blood flow to the intestines, can present in acute or chronic forms, with acute mesenteric ischemia (AMI) often representing a life-threatening emergency. A thorough review of literature and imaging data was performed, focusing on both acute (arterial occlusive, embolic, thrombotic, non-occlusive, venous) and chronic mesenteric ischemia (CMI).
Read more Findings and procedure details DEFINITIONSMesenteric ischemia, characterized by insufficient blood flow to the intestines, can present in acute or chronic forms, with acute mesenteric ischemia often representing a life-threatening emergency.The spectrum includes: Acute mesenteric ischemia (AMI): Thrombotic AMI, Embolic AMI, Non-occlusive mesenteric ischemia (NOMI), Venous AMI. Chronic mesenteric ischemia (CMI). ANATOMYThe small and large bowel receive blood supply from three primary arteries: the celiac trunk, superior mesenteric artery (SMA), and inferior mesenteric artery (IMA) (Fig. 1). The celiac trunk supplies blood from the distal esophagus to the...
Read more Conclusion Acute mesenteric ischemia is a radiologic emergency with a wide spectrum of imaging findings. Early identification is vital to guide prompt treatment. Chronic mesenteric ischemia requires detailed vascular imaging for diagnosis. Familiarity with the imaging patterns is essential for radiologists to improve diagnostic accuracy and patient outcomes.
