A study was done in 50 superior mesenteric arteries for finding its different pattern of origin and colic branches.
The observatory findings are more or less coinciding with that of the observations of the eminent scientists in the field.
The following findings have been observed:
• Superior mesenteric artery and Splenic artery arising as a common trunk from the abdominal aorta.
• Superior mesenteric artery and hepatic artery arising as a common trunk from the abdominal aorta.
• Superior mesenteric artery and inferior pancreatico duodenal artery arising as a common trunk from the abdominal aorta.
• Distance between the origin of coeliac trunk and superior mesenteric artery, ranged from 2mm to 20mm.
• Inferior pancreatico duodenal artery arising from the posterior surface of superior mesenteric artery and also from the 1st jejunal branch.
• Middle colic artery and right colic artery arising as a common trunk from superior mesenteric artery.
• Double middle colic arteries, both from the superior mesenteric artery or one from superior mesenteric artery and the other from the right colic artery.
• Double right colic artery.
• Right colic artery and ileocolic artery arise as a common trunk from superior mesenteric artery.
• Right colic artery arising from the ileocolic artery.
• Ileocolic artery and right colic artery had a common trunk from superior mesenteric artery.
• Ileocolic artery arising from the right colic artery.
• Appendicular artery arising from inferior division of ileocolic artery.
• Double appendicular arteries, one from ileocolic artery before division and other from inferior division of the ileocolic artery or one from the ileocolic artery and other from anterior or posterior caecal artery.
With the knowledge about the aberrant vessels by their origin or by their branches and termination, the surgeon can take adequate precautions against the bleeding vessels in the operating field.
The anatomists can stress these variant occurrence and their clinical importance while teaching and guiding the medical students.
Hereby I hope this analysis of mine about the variational and surgical anatomy of the superior mesenteric artery will be of definite use and guide to the operating surgeons, radiologists and anatomists in the medical field
