Study of the vascular segmentation of the spleen

An experimental study of the spleen segmentary vascularisation was conducted by the "injection-corrosion" technique. Most often was found the well known existence of two lobes, each being divided into two segments, separated by asvascular planes. However we stress the possibility of deviation from this schema, either by the existence of supernumerary polar arteries, or by anomalies in the distribution of segmental arteries.
