Double inferior polar arteries of human spleen – A case study

Spleen is the largest lyruphoid organ in the body. Its supplied by splenic artery which divides into 2–3 divisions at the hilumn. These divisions give rise to a number of segmental branches which enter the spleen through the hilum. The present study was undertaken in Department of Anatomy J.J.M.M.C. Davangere where 40 spleens were studied from formalin dried cadavers. Superior and inferior polar arteries supply the superior and inferior poles of spleen, the origin of superior and inferior polar arteries are highly variable.

The aim of the present study is to know the origin of inferior polar arteries which are highly variable in origin and size. Hence the knowledge of vascular segments of spleen is needed at the time of operation when splenic conservation is considered.
