Challenging Conventional Treatment: Retrograde Implantation of a Covered Stent in Superior Mensenteric Artery Occlusion Case.

This case report describes a novel endovascular technique for treating superior mesenteric artery (SMA) occlusion, a condition leading to chronic mesenteric ischemia (CMI). Traditional treatment methods for CMI, primarily due to SMA stenosis, are often complex and risky, particularly for patients unsuitable for conventional surgery. This study details the application of retrograde recanalization followed by the deployment of a VIABAHN covered stent in a patient with complete SMA ostium occlusion. The procedure's success in re-establishing mesenteric blood flow demonstrates its potential as a less invasive, safer alternative to traditional surgical approaches. This technique's innovation lies in its retrograde approach, allowing for effective treatment in cases where antegrade access is unfeasible. The patient showed significant symptom improvement without procedural complications, underscoring the method's efficacy and safety. : These findings suggest that retrograde stent implantation can be a viable option for managing SMA occlusions, especially in high-risk surgical cases. The successful application of this technique in this case contributes to the evolving landscape of endovascular interventions in vascular surgery and offers a promising direction for future research and clinical practice in treating SMA-related conditions.
