Chronic mesenteric ischemia

Area of Science:

• Vascular Surgery
• Gastroenterology
• Radiology

Background:

• Chronic mesenteric ischemia (CMI) is an uncommon but significant cause of abdominal pain, accounting for 5% of intestinal ischemic events.
• Atherosclerotic occlusion or stenosis of splanchnic arteries is the most frequent etiology, leading to collateral vascular formation.
• Symptoms manifest when at least two of the three major splanchnic vessels are compromised.

Purpose of the Study:

• To review the clinical features, diagnostic modalities, and therapeutic options for chronic mesenteric ischemia.
• To emphasize the importance of early recognition and intervention in managing this condition.

Main Methods:

• Review of noninvasive diagnostic methods including computerised axial tomographic angiography (CCTA), magnetic resonance angiography (MRA), and duplex ultrasonography.
• Inclusion of invasive catheter angiography as a diagnostic tool.
• Discussion of therapeutic alternatives such as embolectomy, thrombolysis, and percutaneous angioplasty with stenting.

Main Results:

• Intestinal angina, weight loss, and sitophobia are characteristic clinical presentations.
• Noninvasive and invasive imaging techniques aid in diagnosis.
• Treatment strategies vary based on disease extent and location, with endovascular interventions gaining prominence.

Conclusions:

• CMI, though rare, can lead to debilitating symptoms and potentially life-threatening acute mesenteric ischemia.
• Prompt diagnosis and management are vital for preventing bowel infarction and mortality.
• Significant asymptomatic mesenteric vascular disease carries an 86% risk of symptom development and a 40% mortality rate.
