Isolated superior mesenteric artery (SMA) dissection without involvement of the aorta and the SMA origin is unusual. We present a case of an elderly gentleman who had chronic abdominal pain, worse after meals. CT angiography, performed on a 64-slice CT scanner, revealed SMA dissection with a thrombus. A large artery of Drummond was also seen. The patient was managed conservatively.

Response was better in the study group but statistically insignificant, acute reactions were manageable, and there was decrease in drop outs due to completion of treatment at a stretch, but larger number of patients and longer follow-up are required to arrive at concrete conclusions.
