MORPHOMETRIC STUDY OF SPLEEN
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2019, Vol 8, Issue 18
Abstract
BACKGROUND Spleen is the largest lymphoid organ playing a vital role in the defense mechanism of the body and performs a unique function of filtration of blood by phagocytes. We wanted to study the morphological variations and to compare the results with previous findings and to unearth the so far unnoticed features of the spleen. METHODS This is a descriptive study. 60 human cadaveric normal spleens were studied. The morphological features of the spleen such as shape, surfaces, poles, and measurements of borders, weight, thickness, notches, fissures, lobes, lobules, hilum and accessory spleens have been studied. RESULTS Spleens showed many shapes and they were classified into 15 forms. Most of the spleens were wedge shaped [31.66%, ], followed by triangular [11.6%], rounded [10%], tetrahedral [8.3%], irregular [8.3%], oval [5%], bilobed [5%], trilobed [5%], heart shaped [3.3 %], cone shaped [1.6%], tent shaped [1.6%], orange peel [1.6%], foot shaped [1.6%], fork shaped [1.6%] and lobulated [3.3%]. Length, breadth, thickness and weight, varied between 6 cm-15 cm, 4.5 cm-11.5 cm, 1.5 cm-3.5 cm and 70-180 grams respectively. Medial and lateral ends, surfaces, borders, notches, lobes and lobules and fissures were noted in most of the spleens. In circular, irregular conical, tent shaped spleens, the borders could not be identified properly. 96.6% of spleens showed notches on their superior border. 3.4% of spleens were without notches. Notches were absolutely absent in inferior border. Fissures were noticed on both the surfaces in 11.6% of spleens. Two accessory spleens were noticed out of 60 spleens. One accessory spleen was found near the hilum. It was pea shaped and pea sized. Another accessory spleen was oval in shape situated on a deep depression on the visceral surface of the spleen connected to it by a bridge of splenic tissue and supplied by small branches of splenic artery. It measured about 3 cms. in diameter. CONCLUSIONS The knowledge of different shapes of the spleen, variations in dimensions, absence/presence of notches in unusual sites, occasional presence of fissures on the surfaces, lobes and lobules and presence/absence of accessory spleens is important for physicians, surgeons, radiologists and anatomists.
