In excising the spleen it is important to remember that the splenic vessels lie 

 between the two layers of the lieno-renal ligament, and not in the gastro-lienal 

 ligament, which contains the short gastric vessels. In a floating spleen these two

 little above the inferior basal angle of the spleen.
