Topographic location and branching pattern of the superior mesenteric artery with its clinical relevance: a cadaveric study.

The most common topography of origin of the SMA was opposite the lower third of L1. The celiac-superior mesenteric relationship was most consistent than between any other two points on the abdominal aorta; 85% of the SMAs were concentrated within a space of 1.00 cm (0.60-1.50 cm) from the CT. Type A branching pattern was most commonly seen in our study population.
