Abstract
Background: Acute obstruction of the mesenteric artery induced by aortic dissection frequently causes life-threatening visceral organ ischemia. We report a case of emergency endovascular stent graft placement with Stanford type A dissection with visceral ischemia. Case: A 66-year-old man with severe chest and back pain of sudden onset was transported to our hospital. After admission, he had abdominal pain and repeated vomiting. Arterial blood gas analysis showed progressive acidosis. Contrast-enhanced computed tomography indicated that the true lumen was severely compressed by the false lumen, and occlusion of the origins of the celiac artery and the superior mesenteric artery. Since the entry was located at the proximal descending aorta, we performed emergency endovascular stent graft placement for entry closure. Results: After the procedure, the mesenteric ischemia improved rapidly, and the postoperative course was uneventful. Conclusion: Our experience suggests that emergency endovascular stent graft placement can provide an option that is less invasive, more prompt and effective treatment for patients with mesenteric ischemia resulting from acute aortic dissection.
