Background and Aim:The spleen is the largest lymphoid organ in the human body. It is highly vascular andfriable.It is affected in various clinical conditions like infections and storage functions. The aim of the study isto find out the morphological variations of spleen.The present study is undertaken to report the prevalence ofvariations involving weight, length, breadth, width (thickness) and the number of notches of spleen in thecadavers of South India population.Materials and Methods: The study was done in 50 human adult cadaveric spleens of both sexes preserved in 10%formalin. The weight, length, breadth, thickness were measured and the number of notches present were noted.Results:The weight of fifty spleens studied varied from 80- 200gm in 43(86%), 201-300gm in 6 (12%) and above300gm in 1(2%) , the length of the spleen on the visceral surface measured from upper pole to lower pole variedfrom 6-9cm in 25(50%) and 10-15 cm in 25 (50%) .The breadth of the spleen varied from 2-5 cm in 16 (32%)specimen, 6-9 cm in 32 (64%) specimen and 10-13 cm in 2 (4%) specimen respectively. The width (thickness) takenat the midpoint of the spleen varied from 2-4 cm in 48 (96%) specimen and 5-6 cm in 2 (48%) specimenrespectively.In the present study the number of notches varied from zero to six, but in most of the specimens therewere one or two notches.However accessory spleen was not found at the hilum of thespleen.Conclusion:The findings of the present study will be of fundamental importance to the physicians,surgeons andradiologists.It also furnishes much insights on clinical utility and significance of spleen.

Background: In the medical field, the trend of the surgical branches has moved towards minimal invasivesurgeries for reasons of decreased morbidity and mortality. To achieve this is thorough knowledge of the anatomy,with the variations of the concerned structure is required. Hence for a structure like superior mesenteric artery,the anatomic variations of its origin and branching pattern is important for accurate interpretation in diagnosticimaging, as well as in deciding the optimum elective procedure in surgical radiological, and interventionalmanagement.Materials and methods: The study was carried out in 50 well embalmed cadavers of South Indian origin irrespectiveof age and sex. Variations in the branches of superior mesenteric artery were noted.Results: Inferior pancreaticoduodenal artery arose from the first jejunal artery. Middle colic and right colicarteries arose as common trunk. The right colic artery was absent. Ileocolic artery arose as common trunk withright colic artery.Conclusion: A thorough knowledge of the anatomy of colonic mesenteric arteries is necessary to accomplishsuccessful uncomplicated abdominal operations, especially laparoscopic colonic resection for cancer usingproximal vascular ligation and wide-en-block resection in which the mesenteric vessels cannot be palpated.
