Background: Introduction of laparoscopic surgical methods requires exact knowledge of the topography of the spleen and its surrounding. Further advances in splenic conservative surgery are dependent on better knowledge of vascular anatomy of the spleen. Hence segmental arteries of spleen are of great surgical importance and their early identification in splenic trauma will lead to enhanced splenic conservation. Materials and methods: Present study carried out on 50 human spleen by dissection, silicon injection and radiological methods. We found different types of variations in hilar and segmental branching pattern of splenic artery. Observations and Results: in present study splenic artery divided in two primary branches in 86% and in three primary branches in14% of the spleens. superior polar branches were found in 44% while inferior polar branches were in 52% of the spleens. Two segmental branches found in 24%, three segmental found in 50%, four segmental in 18% and five segmental in 8% of the specimens. Intersegmental anastomosis found in 2% of spleens. Discussion: These segmental resection of spleen and further advances in splenic conservation are dependant on better understanding of vascular anatomy of the spleen.
