Contemporary Strategies for Mesenteric Malperfusion in Acute Aortic Dissection

Mesenteric malperfusion is a rare complication of aortic dissection associated with high mortality. Diagnosis requires a high degree of suspicion as treatment is time-sensitive, necessitating early revascularization to prevent bowel necrosis, sepsis, and multi-organ failure. Advances in endovascular techniques have improved outcomes and survival over traditional approaches. Management of type A aortic dissection with mesenteric malperfusion has shifted from central aortic repair first to a two-stage approach with revascularization and delayed aortic repair. Thoracic endovascular aortic repair has become the standard treatment for type B aortic dissection with mesenteric malperfusion. However, finding the balance between aortic repair and treating mesenteric malperfusion remains a challenge. This review highlights current strategies and promising research into new endovascular techniques and refining treatment pathways.
