摘要：Background and Aims: Spleen is supplied principally by splenic artery. In some spleens, additional arteriessupply the superior or inferior pole of the spleen. The presence of such polar arteries in addition to the mainsplenic artery provides a firm base for the preservation of spleen during partial splenectomy and splenic arteryembolization procedures. The aim of the present study is to observe the incidence of inferior polar artery and itsorigin in adult human spleens.Materials and Methods: After obtaining ethical committee clearance, this observational study was done inGovernment Stanley Medical College and Hospital. Fifty adult human spleens were dissected out along with theentire course of splenic artery from the embalmed cadavers (35 males and 15 females). The spleen artery and itsbranches was traced by piecemeal dissection. Inferior polar branches, if present were dissected and traced.Results: In the present study, Inferior polar artery was found in 72% of the splenic specimens. The inferior polarartery was originating from splenic artery in 55.56 %, left gastoepiploic artery in 25% and inferior terminalbranch of splenic artery in 19.44% of splenic specimens.Conclusion: Inferior polar artery originates from the splenic artery directly or inferior terminal branch of splenicartery or from the left gastroepiploic artery. The knowledge of the presence of inferior polar artery and itsvariations in origin is important for Surgeons, Interventional Radiologists and Surgical Gastroenterologists forperforming surgical procedures involving the spleen.
