Isolated dissection of the main trunk of the superior mesenteric artery

A 47-year-old male with sudden onset of abdominal pain was diagnosed as having a tight stenosis and a long irregular narrowing of the main trunk of the superior mesenteric artery (SMA), which induced transient ileus. The patient was successfully treated by a patch angioplasty using an autologous saphenous vein. An intraoperative finding revealed the isolated dissection of the SMA, and a histological examination confirmed the dissection of the SMA, in which false lumen was thrombosed.
