Morphometric Analysis of the Human Spleen

Abstract

BACKGROUND With respect to its size, shape, weight, notches & fissures, spleen is a highly variable organ. It is otherwise very difficult to analyse whether the spleen is normal or abnormal on the basis of its shape; therefore this study has been undertaken to find out percentage of various shapes and other morphometrical parameters of spleen. Accurate knowledge of splenic morphology is essential prior to performing any surgical procedure or making any radiological interpretation with regard to spleen as it reveals many variations in shape, size, notches & fissures. MATERIALS AND METHODS The present study is a descriptive study conducted in the Department of Anatomy, K. D. Medical College, Mathura, U.P. 60 adult human cadaveric spleens were included. Sexual dimorphism was excluded from the research. The spleens were dissected from the abdominal cavity and a morphometric analysis was done with the help of digital sliding calipers. Data obtained was compared with data available from previous studies after its tabulation and statistical analysis. RESULTS 60 human spleens were morphologically analysed in detail. Wedge-shaped spleens were most commonly noted. Mean length was calculated to be about 10.5 cm. Mean breadth was calculated to be about 7.5 cm. Mean width was calculated to be about 4.25 cm. CONCLUSION Studies on the morphometry of spleen will be of interest not only from academic point of view but also for operating surgeons and interventional radiologists. Detailed knowledge on spleen is important to avoid and prevent any complications and to obtain a good operative, as well as diagnostic intervention.
