Pancreatic blood circulation system and surgical procedure. (a) The visceral contents were externalized after a Balb/c mouse was killed. The photo was taken under a dissecting microscope, and was processed with Photoshop to remove the reflected light. The lieno-pancreatic artery and pancreatic vein (dotted white lines) were invisible under the microscope. (b) Schematic illustration of the pancreatic blood circulation and surgical procedure. The celiac trunk was clamped with a hemostatic forceps (arrowhead) before placing ligations sequentially on illustrated vessels (dotted lines). The arrow indicated the injection site on the celiac trunk. 1, Celiac trunk; 2, lieno-gastric artery; 3, common hepatic artery; 4, lieno-pancreatic artery; 5, hepatic portal vein; 6, pancreatic vein.
