Abstract
Spontaneous isolated dissection of the superior mesenteric artery (SMAD) is not still well known. We retrospectively analyzed our 30 patients with SMAD to elucidate the treatment strategy and long-term follow-up outcomes. Due to severe abdominal symptom we performed a stents deployment and surgical reconstructive surgery for each one case. Anerysmectomy and bypass surgery was performed for a patient with aneurysmal change. Other 27 patients were managed conservatively. SMAD patients had only two vascular events (renal infarction and graft occlusion), and showed good prognosis for 6–146 (mean 69) months follow-up. We found that there is a few SMAD patients necessary of invasive management at acute phase and that most patients are safely conservatively treated with good prognosis.
