The spleen preservation by distal pancreatic resection can be performed either with spleen vessels preservation or with the ligation of the least. The experiment evolved ligation of all gastric arteries but the short gastric arteries in 20 cadaveric organocomplexes, followed by ink perfusion through the left gastric and left gastro-epiploic arteries. The study was amplified with the intraoperative dopplerography of portal arteries of the spleen after crossclamping of the left gastro-epiploic and short gastric arteries. Ten patients after distal pancreatic resection with spleen preservation and splenic vessels ligation had the CT-angiography before and after the surgery. All the conducted studies demonstrated the incapability of short gastric arteries to supply the satisfactory spleen perfusion. The left gastro-epiploic artery proved to be the main source of splenic blood supply after splenic vessels ligation.
