IGIRI, Oyono; EKONG, Moses Bassey; EGEMBA, Geoffrey Okechukwu  e  ASUQUO, Olaitan Ruth. The Pattern of Arrangements and Distributions of the Superior Mesenteric Artery in a Nigerian Population. Int. J. Morphol. [online]. 2010, vol.28, n.1, pp.33-36. ISSN 0717-9502.

This study was to ascertain the pattern of arrangements and distributions of the superior mesenteric artery (SMA) in a Nigerian population. Seventy-five cadavers certified as Nigerians were obtained from the dissecting room of the Department of Anatomy, University of Calabar after ethical approval from the Institution's Ethics Committee. Their abdomens and their contents were excise to expose the vessels. Based on the pattern of arrangements of the SMA, the cadavers were grouped into three (A, B, and C). Group A had 45 cadavers and this constituted 60% which were similar to the commonly documented patterns. Groups B and C had 20 and 10 cadavers respectively constituting 26.7% and 13.3% pattern of arrangement, some of which have not been documented before. In conclusion these peculiar patterns in this population are to be noted in surgical procedure, since damage to these variant vessels may result in severe haemorrhage that may lead to other complications.
