Quantification of Mesenteric Blood Flow by Magnetic Resonance Flow Imaging in Patients with Arterial Dissection

: Mesenteric ischemia is an infrequent, but potentially dangerous, complication of aortic or mesenteric artery dissection. Severe mesenteric ischemia presenting as a malperfusion syndrome, caused by aortic dissection or isolated mesenteric dissection, should be treated immediately by central aortic repair or angioplasty. However, treatment of non-critical, symptomatic mesenteric ischemia without narrowing true lumen of the aorta or localized mesenteric artery dissection was difficult. We treated two distinctly different cases of non-critical, symptomatic mesenteric ischemia superior mesenteric artery ischemia needing intensive care and mesenteric blood flow was determined by quantification with cine-phase contrast magnetic resonance imaging.
