Endovascular therapy for chronic mesenteric ischemia

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Gastroenterology

Background:

• Chronic mesenteric ischemia (CMI) results from obstructive disease of the superior mesenteric artery (SMA) and celiac trunk.
• Endovascular therapy presents a minimally invasive alternative to traditional surgical interventions for CMI.

Purpose of the Study:

• To evaluate the effectiveness and durability of endovascular treatment for obstructive disease affecting the SMA and celiac trunk.
• To assess technical and clinical success rates, complication incidence, and long-term outcomes in patients with CMI.

Main Methods:

• Retrospective analysis of nine patients (15 lesions) treated for CMI.
• Data collection included technical/clinical success, complications, patency rates, and patient survival.
• Mean follow-up duration was 31 months.

Main Results:

• 100% primary technical and clinical success with no perioperative mortality.
• Two patients experienced major complications (pseudoaneurysms).
• Midterm patency rate was 78% at 2 and 5 years, with survival estimates of 85% and 68%, respectively. All patients reported symptom relief.

Conclusions:

• Endovascular treatment is a feasible option for chronic mesenteric arterial obstructive disease.
• The procedure demonstrates a low complication rate and acceptable midterm results.
• Sustained clinical benefit and patency support endovascular therapy for CMI.
