How to manage chronic mesenteric ischemia? A deliberated strategy.

Chronic mesenteric ischemia is a rare and challenging clinical entity with non-specific complaints. It concerns mainly elderly patients with a diffuse atherosclerotic burden affecting other vascular beds. Most surgeons have limited experience with the management of symptomatic occlusive disease of the superior mesenteric artery or coeliac trunk. Last decades, the mesenteric revascularisation debate has also been implicated by the endovascular vogue. An endovascular-first strategy has been adopted in most centres, considering its less invasive character, with lower peri-procedural morbidity and mortality and more rapid recovery. The volume of mesenteric artery stenting has steadily increased over time. However, the long-term results of percutaneous mesenteric angioplasty and stenting are worse than those obtained with open surgery. Currently, many centres reserve open repair for cases in whom PTA failed. This extensive literature review aims to orientate decision-making and choice of revascularisation modality for chronic mesenteric ischemia, considering a significant patient heterogeneity.
