Figure 1 Sonogram and conceptual diagram of relationships between spleen vessels and pancreas. A: All spleen artery segments were located at the antero-superior border of pancreas (Type I); B: One-fourth of the distal spleen artery segments were located at the antero-superior border of pancreas (Type II); C: Two-fourths of the distal spleen artery segments were located behind or in the pancreas (Type III); D: Three-fourths of the distal spleen artery segments were located behind or in the pancreas (Type IV).
