Comparing stent treatments for chronic mesenteric ischemia

Copenhagen Mesenteric Stent Study - A Randomized Trial of Stent Versus Covered Stent Treatment for Chronic Mesenteric Ischemia

Not applicable Interventional Rigshospitalet, Denmark · NCT05244629

This study is testing whether covered stents work better than bare metal stents for people with chronic mesenteric ischemia to see which one helps them more after a year.

What this trial studies

This trial evaluates the effectiveness of bare metal stents (BMS) versus covered stents (CS) in treating chronic mesenteric ischemia (CMI), a condition caused by narrowed arteries supplying blood to the intestines. Patients with significant stenosis of the superior mesenteric artery will be randomly assigned to receive either type of stent. The primary outcome measured will be stent patency one year after placement, along with assessments of complications, reoperation rates, quality of life, and mortality reasons. The study aims to provide clearer evidence on the benefits of using covered stents over bare stents.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with symptomatic chronic mesenteric ischemia due to significant atherosclerotic stenosis.

Not a fit: Patients with non-atherosclerotic causes of mesenteric ischemia or those experiencing acute mesenteric ischemia will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with chronic mesenteric ischemia, potentially reducing symptoms and recurrence rates.

How similar studies have performed: While the use of covered stents is increasingly supported, the level of evidence is limited, indicating that this approach is still being evaluated.
