Axillary to Superior Mesenteric Artery Bypass as a Viable Solution for Chronic Mesenteric Ischemia.

Chronic mesenteric ischemia (CMI) is a progressive condition that primarily affects the elderly, causing chronic abdominal pain and malnutrition. Timely treatment is essential to prevent further deconditioning or bowel ischemia. Surgical repair options include both endovascular and open procedures. We present the case of a patient with CMI and diffuse atherosclerotic disease of the aorta, treated with a left axillary-to-superior mesenteric artery (SMA) bypass. This case highlights axillary-to-SMA bypass as a novel and effective solution for CMI in patients with complex vascular anatomy and diffuse vascular disease, providing a viable alternative when traditional methods are contraindicated. Following the procedure, the patient experienced resolution of abdominal symptoms, and a six-month abdominal CT scan confirmed a widely patent bypass.
