Our objective was to detail imaging and clinical course of celiac and or SMA dissections. Methods We conducted a retrospective search from 2004 to 2010 using “celiac and/or SMA dissection” keywords. Analysis of medical record and imaging at diagnosis and follow-up was performed. Dissections for any reason without aortic dissection were included. Results Twenty-four celiac and 18 SMA dissections were detected in 38 patients. One third of the dissections diagnosed with interactive multiplanar reconstruction/maximum intensity projection (MIP)/3-dimensional (3D) rendering were missed on standard imaging planes. No patients had bowel ischemia or died. Eighty-four percent of the patients were observed, 2 patients received anticoagulation, 2 patients received surgical repair, and 3 patients received stenting. Twenty-three of 25 cases treated with observation exhibited no change or improvement/resolution (2/25) with 20.9-month mean follow-up. Conclusion Most isolated celiac and SMA dissections were asymptomatic/incidental, supporting observation and surveillance with intervention reserved for vascular compromise. Interactive multiplanar reconstruction/maximum intensity projection/3D rendering can increase diagnostic sensitivity. From the Russell H.
